House arrest: it's not fun as you have found out. Being confined to your own home by choice is one thing but when you don't have that choice considering you have an unstable amount of demonic power inside you which is slowly killing you is a completely different case. Sure, it had only been a day since the ambush that left you in this situation but the fact that you were a prisoner in your own home really made it feel longer.
You couldn't go out due to the circumstances and the extra knowledge that death was a high probability was not comforting either. And then there was the fact that there was no known way to drain the demonic inside you which only made things worse.
At least there were visitors during the day.
Asia paid a visit to see how you were holding up and if you were in need of healing due to the demonic energy being detrimental to a fully human body. She stayed for a bit after a quick healing just to make sure you were healthy enough before bidding you goodbye. Then Rias arrived and she had good news, kinda. She said that she had an idea of how to decrease the pent up demonic power trapped inside you, draining it to more stable levels so that you have more time to find a way to fully drain it.
Of course you were eager to know what she had in mind but when asked, Rias didn't give a verbal response straight away. Instead, what she did was take a hold of your hand and lead the way to the stairs where she pulled you up towards your bedroom.
Upon arrival, you quickly found yourself shoved onto your bed as Rias stood before you. "Let me drain it, let out as much of it as you can on me, Y/n" she said in a seductive voice before straddling your lap and pushing you onto your back which left you staring up into Rias' eyes. "What are you talking about?" You asked, obviously having a very clear idea but you just needed the confirmation.
Rias smiled down at you and replied; "I've come up with the idea of absorbing as much of the demonic energy within me, drain it from you to bide you more time". That didn't fully confirm your idea of what she had in mind but what Rias did next definitely did as she leaned close, her lips turned up as she breathed gently against your cheek. Her fingers grazed your cheek as she spoke quietly; "let me drain the energy within you, let as much of it out on me as possible, Y/n, we need to have sex" she said and your face went blank; how was you supposed to respond to such a statement?
Rias kept her fingers tracing over your cheek before whispering that she wanted to help you. "Let me help you, let me at least try to save you" she spoke softly before kissing you. You really didn't know how to respond to this, however, your body definitely seemed to as you leaned in to the kiss; you returned it as she pushed to deepen it before finally parting back to smile down at you again.
"I'd be lying if I said coming to this conclusion didn't excite me a little" Rias admitted with a smile on her lips as she leaned close again, voice soft as she confessed that for so long now she has wished for the two of you to be together. She wished for you to have her intimately; and here was that chance. "Even if it's to keep the demonic energy inside you stable, I'm happy to do this" she spoke softly but you didn't respond, you couldn't. Seriously, what could you say in response to such a proposition?
All you could do was just look into Rias' eyes as she sat atop you before your faces grew closer again; but you weren't really sure who was closing the distance. What you did know however was the feel of Rias' lips against yours, soft and gentle which was surprising considering she was a devil herself and the way her hips ground down in your lap to excite you definitely caused a stir. Your hands reached to her hips, Rias staring down gently as your lips parted so she could sit upright in your lap,
You could then only watch as Rias stripped of her Kuoh uniform top, her bra being the only thing remaining to conceal her bust from view and you couldn't help as your hands reached upwards to remove it too. There was no opposition to this from Rias as she happily let you free her chest and watched with amusement as you stared in awe of her bountiful bust that was tantalising to touch; she even urged you to touch them by pulling your hands to grope her. Then her voice whispered for you to touch her and you responded by curling your fingers into claw shapes and dug them into Rias' chest which made her moan at how you felt her body.
Rias smiled as you touched her before you sat up and leaned your head to take her nipple into her mouth, sucking on it as Rias hugged your head and ground down in your lap again. This caused even more stirring in your pants as you were growing an erection that was begging for freedom.
This led to the devil atop you to slide back and reach down into your lap to palm your crotch as she leaned to your ear. "I'll do my best for you, Y/n, I just ask that in return you do the same for me" she whispered before unzipping your pants, Rias' blue eyes locked onto yours as she crawled back and knelt before you. Her hand was wrapped around your erect penis, her touch exciting it before you watched her lean down and kiss the tip whilst gazing up at you.
Rias parted her lips around the tip and lowered her head down onto your shaft, her mouth enveloping its length before rising back up once more to again kiss the tip. This is the pattern which she steadily repeated: envelop your cock, swirl her tongue around it before coming back up to purse her lips to the top.
The feeling this created was amazing and you couldn't help but lean your head back to just enjoy the blowjob you were receiving from the red headed devil as she bobbed along your shaft. Then you heard her moan, feeling the vibrations of her voice as it rumbled around your cock. Rias' eyes stared up into yours as she lifted her head back to run her tongue along the underside of your shaft before brushing her crimson hair aside as she again took your cock into her mouth and started bobbing at a more rapid pace. The result of this was even more pleasure and you moaned from the feeling rushing over you.
The moist warmth around your shaft felt incredible and then the pace in which Rias was bobbing her head, combined with her voice rumbling around you, only added to it. All this was taking place as her eyes gazed up at you, staring intently yet almost lovingly into your own as she blew you.
Then Rias again lifted her head back to kiss the tip of your cock. "You're really big, Y/n" she spoke in a seductive voice before applying attention to just the head of your shaft, Rias' lips sucking on it as a means to coax you to a climax while her hand wrapped around its length to pump along your shaft. And with all her efforts she was succeeding. Rias was bringing you close to your release with her ministrations and so you gave a word of warning to the devil servicing you, but even with that warning she was surprised when you came.
Rias never expected you to release so much as a thick load of cum shot from your cock into her mouth. Rias' cheeks puffed out as she lifted her head back to try and swallow what landed in her mouth as the rest of your cum landed on her face and chest.
"There's so much" she breathed as she wiped your load off her face before looking at you. Your expression was sheepish as you apologised but Rias shook her head and said it was fine. "I can sense the demonic energy in your essence, it's best to release a lot so let me have as much as you can" she said as she stripped out of the remained of her clothes so you could eye the full naked beauty of the daughter of the Gremory house as she stood before you.
Rias then again climbed to sit astride in your lap, her pussy lips rubbing against your cock as she leaned to your ear to whisper; "release as much as you can, I want to help you but forgive me if I lose focus on that as I've been wanting this for a while". Rias then kissed your cheek as she began to descend herself, taking you inside of her as she lowered down into your lap.
Your hands took a firm grip on Rias' hips as she penetrated herself on you, her vaginal walls wrapping around you tight yet snugly at the same time as she accommodated your size with a long moan. Her hands also reached to hold onto your shoulders with a tight grip as you felt yourself push through a barrier; Rias' hymen which signalled this to be her first time. Her body stiffened at this as she pushed against you, her breasts to your chest as she laid atop you with shaking breaths,
"Are you ok?" You asked with concern to which Rias lifted her head to look at you with a smile and tears in her eyes. Her fingers traced across your cheek in such a tender notion, one too tender for a devil, as she replied; "I'm more than ok, it's you who needs to be satisfied".
With that being said, she pecked your lips before slowly rolling her hips, gyrating them as you held her steady. The feeling of her body gripping on you so snugly felt incredible but your thoughts still remained on Rias as you wrapped your arms around her, whispering that she needed to enjoy it as well to which she kissed you. "I will, don't worry, I've been wanting this for a long time so I'll enjoy it, but you are a priority, draining the demonic energy from you is my task above all pleasure" she said before pushing her hands to your chest so you laid flat.
"Let me drain it, let me save you" she breathed before sitting upright and entwining your fingers as she rolled her hips in your lap. Your eyes gazed up at the beauty that was Rias, her body a marvellous display with her chest catching your eyes as her breasts reacted to her gyrations. Soft moans were leaving her lips, crimson locks cascading down her back as she closed her eyes. For a devil, Rias Gremory had an ironically divine looking body. And there you were with a front row seat of her beauty as she started to ride your lap with fervid efforts to satisfy you and bring you to climax.
Her hips started to rise and fall as her pussy gripped around your cock, the friction of your bodies rubbing together bringing pleasure to both of you which made the both of you moan. Then you dropped Rias' hands to grab her hips to steady her as you pushed yours upwards, your cock pushing deeper inside of her which made Rias open her eyes wide with a louder moan than before as you began thrusting upwards.
Her body jolted, breaths gasping as you had an intense pace that pushed you deep into her depths; neither of you expected your capacity but that didn't mean either of you tried to stop. Rias did insist you to relax a little more, to let her do the moving but you didn't listen like you normally would to her word. Your body moved on its own accord as you thrusted upwards into Rias, her pussy enticing you more and more with how she was clenching down around you. Her body was calling for pleasure as much as yours, neither of you could deny it and you resigned to it. Your bodies opted to move together as a compromise and its reward was of sweet pleasure.
Rias was only provoking you anyway. Her, with no pun intended, devilish beauty and the way she moaned and pushed her bouncing bosom out before you spurred you on more. It wasn't intentional but she couldn't ignore the pleasure of the fact the two of you were intimately connected, even if it was to save your life, Rias couldn't ignore the feeling in her chest as she rode against your thrusts.
"Keep going, don't stop now" she moaned as if you needed to be told. You responded by reaching up and grabbing one of her teasing boobs, squeezing it as your hips started becoming more aggressive as they thrusted upwards. The daughter of the Gremory family responded to this by not warning you to know your place, but instead by surrendering to your touch and encouraging you more. This was mutually beneficial after all: not only do you release some of the demonic energy within you, but the both of you get to feel amazing sensations from the methods.
Rias made sure to keep movements on her end as well as she received those thrusts into her, she kept her hips bouncing which of course resulted in her chest heaving as you groped her. Rias' voice kept reaching your ears as she moaned louder and louder; "does it feel good?" She asked and you nodded. Your hips then suddenly began to speed up which caught Rias off guard and she was pulled over the edge of pleasure as she arched her back with a cry of release.
The way she gripped down on you, the way her juices bombarded your embedded cock; there was no way to hold yourself back and so you pulled Rias down against your chest. Your hands held her close as your hips gave a deep thrust upwards as you again came, the two of you joined in release as blissful as it was mutual.
Rias laid there atop you, relishing in the afterglow of orgasm before she gasped as you suddenly flipped your positions. You were now on top of her, your inhibitions cut short as you began thrusting again and Rias was laying unprepared and vulnerable to the pleasure. "Y/n...so soon?, I don't think I can handle it" Rias gasped but your thrusts never ceased, they only built up with aggression as your lips pushed against hers in a deep kiss.
Rias moaned into the lock, feeling your tongue invading her mouth and she surrendered to it. She was a high class devil, her power was beyond anything that you, a simple human, could understand; but there she was surrendering to the pleasure that you were making her feel as her arms wrapped around you.
Your hips kept colliding with hers, wet sounds of your bodies meeting as Rias' pussy sucked you back in every time you pulled back. Both of you had your eyes closed during the kiss but Rias' shot open as you began grunting from how rough you were thrusting. "Y/n, Y/n" she gasped and moaned beneath you, clutching tightly to you, digging her nails into your shoulders as you relentlessly went down on her. Rias was a high class devil, how was she being turned into a moaning mess by you? You're just a human, a human, the human who has managed to capture her heart. "I...love you" she gasped before again climaxing which made Rias hold onto you even tighter as she tried to convey the feelings in her heart and the sensation that was vigorously pounding into her nether regions.
"Y/n, I love you" Rias repeated but you only grunted before latching your lips onto her neck. This resulted in a high pitched whine from Rias as you found her erogenous spot, the place where she was most sensitive to sexual stimulation. She responded with a show of weakness in her inability to contain her moans but that didn't stop you from exploiting her weakness.
Her voice was like music to your ears as you left a love bite; yet even then you continued sucking as her sensitivity was through the roof. This was demonstrated by the fact she climaxed again followed by you burying yourself deep inside her with your own orgasm. But this time you never halted, you kept thrusting with an almost carnal drive behind you as Rias was desperately clutching to you. Your thrusts became even more aggressive which caused the devil beneath you to start gasping for air as she called your name. "What's gotten into you so suddenly? Hah, you're so rough" she moaned before again whining as your lips attacked her neck.
"He's so deep, it feels so good but I'm losing focus, what's gotten into him?" Rias thought as she held your head in place even though you were attacking her weak spot. Her vision was becoming fuzzy but the way you were thrusting so aggressively, so deliberately intensely, Rias' eyes began to roll upwards.
But then, even if for a brief moment, Rias regained her focus as your lips again met hers. She moaned into the lock as she saw your eyes closed and she was about to close her own before yours opened. Red eyes, demonic, blood red irises stared back at her. It all made sense now, the demonic energy inside you was taking over, unleashing the carnal side to you and Rias was on the receiving end of something demonically yet blissfully motivated. Then you broke the kiss to kneel up between Rias' legs, hands on her waist as the slapping sounds of flesh filled the room.
There she laid, twisting and writhing from pleasure. Rias was trying to keep her focus but it all felt too good, she was meant to be prioritising the draining of the demonic energy that was driving you but suddenly there was a part of her that didn't want to. She knew it would be killing you and she felt guilty for enjoying this, "it just feels so good" she thought to herself before she reached another orgasm.
And still, you kept thrusting. "So intense!" Rias thought as your thrusts were pushing so aggressively against her as you grunted with effort. She could feel you so deep inside of her, your hand reached up and began groping and kneading her breast as the other bounced from your thrusts.
This was a far cry to what Rias expected her first time would be: even as a devil she had the mindset of her first time being of her making love with her partner, her hopes of it being you were realised, but here she was being fucked instead and she wasn't minding it one bit. "Cum inside me again, Y/n, release the demonic energy stored inside into me, I'll take it, I'll save you!" Rias moaned loudly as her back arched before she reached for you only to have her hands pinned to the bed as your lips crashed into hers. Your thrusts were so aggressive at this point, so intense and driven by lust and carnal desire that your bed actually began rocking against the wall.
"Y/n!" Rias gasped your name before her eyes widened as you gave one final deep and powerful thrust into her body. The pleasure was immense, mind numbing even as you shot another thick load of cum into Rias. Her thoughts were blank to everything but pleasure as she cried out in one final blissful orgasm of her own; euphoric even as she clutched you close.
Rias Gremory, daughter of the Gremory house, a high class devil. That's who she was; and yet she was laying there, sweaty and in the nude, exhausted and breathless from you, a simple human, having her in bed. There should be a sense of shame from allowing herself to end up like this but instead it was happiness filling her heart as she held you close. Rias had a smile on her lips at the fact that you were her first time and that fact she was to cherish even if you were driven by a demonic curse in the end.
"Ugh, Rias?" You spoke weakly as you lifted your head from the chasm between her fleshy mounds. Before you could continue speaking however, Rias pushed her lips against yours in a deep and passionate kiss as she held your face before parting back with a smile as she asked how you felt now. "I should be asking you that, did I go overboard? I couldn't hold myself back, something just took over" you said before being silenced with another kiss from the red haired devil.
"It's fine, I enjoyed it, I can't take anymore right now but if it's helpful to you then I'd be happy to do this again" she said as you pulled yourself from her depths and the result of your demonic ferocity poured out of Rias' satisfied pussy. "There's so much" she commented, still with a heaving chest as she held her folds apart which only caused more of your mixed cum to pour out. "Y/n, let's do this again sometime" she said and you nodded before collapsing to Rias' side as you suddenly felt drained of your energy.
As you rolled onto your back, Rias snuggled closer and kissed your cheek. "I love you, Y/n" she smiled as you met her gaze. "I...love you...too" you replied before feeling light headed and passing out as Rias smiled and snuggled close to you even more. "I'm so glad to hear that" she breathed as she closed her eyes to relish in the afterglow of such an amazing first time.
Considering the amount of energy exerted through your intercourse, the demonic energy within you had drained to some extent. However, there was still a lot stored up so more sessions would be needed to drain it.
Maybe house arrest won't be so bad after all.
