Yuna had just pinned Asta down, winning their match. The position they were in and her outfit were arousing him. And it didn't help that she was sitting directly on his crotch. Yuna felt something grow and harden beneath her. She blushed immediately when she realized what it was.
"Yuna... I..." Asta started to say but trailed off as he averted his gaze to the side, too embarrassed to look her in the eye. Yuna let go of his wrists and turned his face towards hers. She cupped his face in her hands, looked him in the eyes then closed the distance between them, pressing her lips to his. Asta's eyes widened in surprise but then closed as he melted into the kiss. He then rolled over so he was on top, not breaking the kiss. He licked Yuna's bottom lip, asking for entrance. She parted her lips and Asta slipped his tongue into her mouth. His tongue swirled around inside, leaving no part of her wet cavern untouched. She let him explore the inside of her mouth for a little while more before countering him, their tongues dancing together. Asta pulled away, a silver strand of saliva connecting their tongues.
"Yuna... I've missed you so much. You have no idea how much I've been yearning for you." Asta said, staring lustfully into Yuna's teal eyes with his lime green ones. She reached up and placed her hand on Asta's cheek, caressing him with her thumb.
"I've missed you too Asta." Yuna said as Asta leaned down and kissed her passionately again. He then left a trail of kisses down her neck directly to her sweet spot at the base of her neck close to her shoulder. Asta made note of where it was when Izuku found it when they had a foursome with him and Natsu. He lightly bit down and sucked on the sweet spot on Yuna's neck, making her moan and arch her back out of pleasure. She wrapped her arms around him, one hand on his back and the other tangled in his hair. Asta's hands roamed up and down her body, stopping at her breasts. He slipped his hands underneath her sports bra and massaged her breasts directly.
"A-Asta~" Yuna moaned out as he lightly pinched the pert buds on her mounds of flesh. She autonomously pulled her legs in, her knee brushing against Asta's clothed erection. He pulled away from her neck, smirking contently at the mark he left behind. Yuna looked up at him with yearning.
"Asta please... I want you inside of me." Yuna said as she fiddled with his belt buckle. She didn't even care that they were outside and vulnerable to exposure. She just wanted to get swept away in the moment. Asta nodded and finished unbuckling his belt and took off his pants and boxers. His erection sprung up, freed from its restraints. Now that he was completely naked, he started to undress Yuna. She raised her arms so that he could pull her sports bra up off over her head. Then he grabbed her leggings and panties and pulled them off her legs in one swift movement. Yuna undid her ponytail, putting the hair tie around her wrist so she wouldn't lose it. Asta then nudged the tip of his penis against her folds and slowly began to slide himself inside. Both of them moaning as he entered her.
"So tight... feels so good just going inside you~" Asta breathed out as he went all the way in. He started to thrust at a medium pace, restraining himself. He remembered the first and only time they had done it, she was in quite a bit of pain at first and he didn't want to hurt her again. But in actuality, his pace was unsatisfactory. Yuna could tell he was holding himself back for her sake.
"Asta... you don't have to hold back. I'm fine. There's no pain." Yuna said as Asta nodded, increasing the speed and power of his thrusts. The change in his pace drastically increased the amount of pleasure both of them were feeling. Their moans of ecstasy rang throughout the open landscape around them as the sun set. Suddenly Asta pulled Yuna up so that she was sitting up in his lap, somehow managing to stay inside her. He continued to thrust as she locked her hands behind his neck. Their lips then met in a hot, passionate kiss as they made love under the stars. Asta pulled away from the kiss then latched onto one of her breasts, gently nipping and sucking on the pert bud. He massaged the other breast with his hand. Yuna's moans only grew louder as he pleasured her chest while thrusting into her. After a while, he switched breasts to give the other the same treatment. Asta loved how Yuna was becoming a moaning mess under his touch. He smirked against her supple flesh. He found her lewd voice and facial expressions so erotic.
"A-Asta... I'm close... Ah~" Yuna moaned out as she felt the tension in her abdomen building up, about to burst. Even without her announcing it, Asta could tell she was close to her climax. He could feel her walls pulsing around his member which was driving him towards his own orgasm.
"Ah~ Yuna... your body... it... it feels like it's trying to milk me of all my sperm. I... I'm cumming!" Asta announced as he thrust upwards one last time, hitting her g-spot hard. The tip of his penis kissed her cervix as he shot his hot seed deep inside her womb. Yuna released at the same time. They both called out each other's names as the came together. The two of them panted as they floated down from their orgasmic highs, leaning against one another's shoulders. Their bodies glimmered in the moonlight from the sweat on their skin from their intense love session. After they had cooled down, Asta and Yuna got dressed and headed back to the church together. When they got there, Yuno, Father, and Sister Lily were outside the church building waiting for them.
"There you are! We've been waiting for you guys to get back for hours!" Father said.
"We were starting to get worried." Sister Lily said as Yuno gave Asta and Yuna suspicious looks.
"What took you guys so long? And why is your hair more messed up than normal Yuna? Were you two...?" Yuno asked trailing off as both Asta and Yuna started to blush.
"W-we just lost track of time. We were really getting into our training. And Asta here just got a little too determined and ended up winning more matches than usual." Yuna lied to cover up the fact that they were actually having sex after their training matches.
"Y-yeah that's all that happened!" Asta said a little frantically. Yuno raised an eyebrow as he switched his gaze between Asta and Yuna.
"Then what was with that blush you two had on your faces when I questioned you." Yuno said as Yuna quickly responded.
"That was because of what you accused us of doing. Almost anyone would get flustered over thinking about that!" Yuna said as Asta nodded his head. Yuno sighed, realizing she had a point.
"I guess you're right. Shall we get you home Yuna?" Yuno said as Yuna nodded. He, Father, and Sister Lily got into position to help Yuna cast the spell to get her home.
"Compound Gargantuan Magic: Door of Fate!" Yuna said as she cast the spell. Asta approached her and grabbed her hand before she stepped through the large runic portal, causing her to look at him. He pulled her towards him and captured her lips with his. When he parted from her, he smiled softly.
"I may not have the ability to feel the presence of mana due to having no magic power, but tonight felt magical. I love you Yuna." Asta whispered into Yuna's ear, making her giggle.
"Oh Asta, I love you too." Yuna said as she reached up and caressed his cheek with her thumb. Asta placed his hand on top of hers, cherishing this moment.
"I'll see you tomorrow for more training." Yuna said as Asta removed his hand from hers as she let go of his face, her warmth quickly leaving his cheek. Yuna walked into the portal and stepped foot into her bedroom back at home. She changed into her pajamas, but before she crawled into bed, she checked her phone for any missed calls or text messages. She was surprised to find a missed call from Izuku. She listened to the voicemail he left her.
"Hey Yuna, it's Izuku. My internship had to end a little early since my mentor got his teaching license revoked for the next six months due to an incident that happened in Hosu City. I'll tell you all about it next time we speak. Anyways I just wanted to let you know I'm home now. I hope your training with Asta has been going well. I'll see you later, bye." Izuku's recorded voice sounded through the phone. Yuna smiled and held her phone to her chest.
"So Izuku is home now. I didn't realize how much I missed him until I heard his voicemail. I've been so busy sparring with Asta lately. Speaking of sparring, Natsu and I used to spar a lot back in the day. Man I miss him a lot too. Maybe I should pay him a visit soon." Yuna said to herself out loud. She plugged her phone in to charge then lay back down. Shortly after, her exhaustion from today's training and love session with Asta overcame her and she fell fast asleep.
