The first thing Stiles felt was the warm hand on his neck as Derek leaned in, kissing his lips and biting them as he pulled away, growling as he spoke: "Turn around..." Stiles whined softly as his body obeyed without thinking, his hips turned and now he was lying flat on his stomach with his ass high, this was easier for Derek to use his ass like he wants to, like he's going to, Stiles can already tell Derek won't go easy on him. He doesn't need lube anymore since his body decided that slicking was a good thing (And it is, since his Alpha likes it, seeing how he is pushing his finger down his ass slowly, to feel it) and he can't help hut blush as Derek inserted two other fingers, his ass alresdy loose enough to take the three fingers inside him without much trouble, which means his body really wants Derek's dick. "So hungry... So needy..." Stiles gasped for air when Derek pulled his fingers out in a single quick movement before pushing them down again, fucking Stiles'ass with his fingers as Stiles gasped. "Alpha-" Derek stopped, his eyes flashing red as he grasped Stiles' bubble butt with a firm hand, saying: "Moan louder, my little mate..."
"Alpha, please don't tease me..." Derek could hear the pout on Stiles' voice, he smiled warmly as his fingers traced up Stiles' back, touching his skin. He felt Stiles tense a little as his fingers brushed through some of his scars, but they were beautiful, they showed how strong he was, how he survived... "So adorable." Derek bit Stiles' cheeks, making the smaller man to moan and shiver, after all, his Alpha just bit him! "Baby, open wide..." Stiles couldn't help but blush when he felt the tongue of his beloved entering his body from behind, it was warm and albeit smaller than Derek's dick, it still felt good and felt even greater when Derek began stroke him slowly, rubbings his thumb on the head of his dick, the most sensitive part. "Alpha, I'm gonna-" It may seem to you that it was too early for Stiles to cum, but Derek was just too good, and their shared link also shared the pleasure and lust they had for each other, Stiles was just very influenced by it.
"No." Derek's eyes flashed red ss Stiles felt his dick being released from the tight grasp that Derek had, denying him of his sweet release. "You will only cum when I say so." It was definitely a command from his Alpha, so Stiles had to obey, but he wasn't so happy on doing so. Derel kept licking him, tasting him as his wet hole, he wonders if Derek is doing all this just to tease him after he pleaded him not to do. Stiled found himself actively pushing against Derek's tongue as the man growled and bit his ass again, only to hear Stiles moan in shameless response as he begged: "Alpha please..." Derek couldn't help but hear the desperation on Stiles' voice, his wolf slowly coming to the surface as his body began to shift and he had long teeth and red eyes. "Tell me baby, what do you want?" Derek's teasing voice made Stiles whine as his muscles throbbed and shivered with Derek's hot breath against his wet and now empty little hole that he wanted it filled so bad!
"Alpha, please, fuck me!" Stiles threw the sliver of shame he still had away as his voice broke into a big gasp as Derek pushed him down, pined him to the ground as he took the rest of his own clothes he still had on out and stood in there, completely naked, just like the man underneath him. His hand came crashing down on Stiles' little white bubble butt, making it look pink with the slap he gave, Stiles surprisingly moaned rather loudly, making Derek stop on his tracks and slap the other cheek the same way, earning another sharp and rather loud moan from his adorable little mate, who was completely red and embarrassed about his reaction at being spanked by the bigger man. "You like that huh?" Derek asked, more surprised than aroused by Stiles' reaction, who was shaking... Derek could feel and smell the arousal coming off of the tiny body of his mate, but he could also smell the salty, wet scent of tears.
Derek immediately stopped everything he was doing and took Stiles by his waist, turning hin around and asking: "What is it, baby?" He expected to see Stiles' sad or even angry face, all he saw was Stiles' absolutely bliss snd arousal as he cried, he could feel the happiness from their bond and apparently his doubts were seen on his face because Stiles just smiled st hin and whispered: "Hm... I just realized, i really fell for you huh? I used to hate pain, but I don't mind when its you, no, i like it more when I'm with you and it hurts." Derek couldn't contain the growl that escaped his lips, but Stiles could and did contain Derek's growls with his own lips, the kiss was more than passionate, it was hot, rough, their lips looked like hungry wolves that wanted to devour everything in its ways, teeth bit their lips in a carnal desperation, Derek couldn't help but whine when he saw the red blood dripping from Stiles' lips- where he had bitten him- thinking he hurt his mate. "Kiss me more, bite me more, be rough with me... I like it." The smile Stiles had, with the blood dripping down his lips, through his neck and on his chest was a view Derek never thought he would find hot, and yet, here he is.
"Stiles... Too late to take it back now." Derek's voice was but a growl, his wolf was completely on the surface and Derek liked it, both of them wanted to please their mate, so they would do so. Grabbing Stiles by the waist, Derek ignored his surprised yipp and without a hint of hesitation, pushed his throbbing penis down his gaping asshole, which made Stilws gasp and groan at the sudden intrusion, his heart was beating like crazy, the pain and pleasure he felt as Derek's penis pressed his prostate aggressively, taking the wind right out of his lungs with the strength behind the movement was... So good. Stiles practically fainted when he felt it move back and hit him hard once again, the same aggressiveness, the same wild and powerful way.
"Argh!" Stiles cried in both pain and pleasure, he didn't know what else but to cry as Derek moved hips with such intensity that he could feel and see Derek and his wolf moving at the same time, it was very sweet and strange to see the ethereal form of the wolf thrusting- It may seem very perverted, but he could see how Derek and his wolf were harmonizing together as the Rut started now. Derek's eyed were glowing red as he moved his hips, Stiles could hear the slapping of their bodies against each other, he could see how it was affecting Derek who kept making pleased noises. Stiled opened his mouth as the lips of his Alpha met his, the sharp teeth of his Beta Shift was clearly felt by Stiles' fragile lips, the rough tongue that pushed down his gaping mouth, rubbing against his own mouth and trading saliva between them. The low growls Derek would make whenever Stiles whimpered when hit in the prostate by Derek's huge dick was... Mesmerizing.
Stiles wanted to feel more.
And feel it he did, when Derek arched back before pushing it down him and cumming inside his little hole, completely filling it with his semen. "Hm... Now I'm curious if you can have puppies..." Derek's voice was still that grunting, husky, sexy deep voice he gets when he is in his Beta Shift, he whispered on Stiles' sensitive ears, making the man shiver as his arousal spiked again. "Well, let's find out."
This time they were on the kitchen of their pack house, Stiles was kneeling in front of Derek as he moved his dick siwn Stiles' sore little throat, its been three days and they only stop to eat and drink and sleep, well, Derek needs those things while Stiles has his magic constantly feeding him, he doesn't need to eat or drink, but he does need to go to sleep. Gagging a little when the dick pulled back, resting on his face, Stiles smiled to Derek who was completely naked as well as he was, his skin was completely clean due to Werewolf regeneration, but Stiles always made sure to mark him all of the time using his magic and willing it to stay longer. Derek had his hand on Stiles' head, pulling his hair as his dick was once again swallowed whole by the welcoming and hungry mouth of his... Stiles' ass is still full of cum, full of Derek's white liquids, a butt plug shoved on his ass to keep the cum there when Derek isn't knotting him, which is something Stiles learned he loved to be knotted by Derek and have him ride on the man's knot, making his gaping hole a gaping crater.
By the time he is done sucking Derek dry for the day, he feels the butt plug slowly leaving his ass and spilling all of the cum that was inside him even on the ground, this made Derek growl at him and say: "Look at all this... Wasted. I guess I'll have to punish you for spilling when i told to to hold it... I'll fill you up again, but if you cum once while I'm filling you up, I'll fuck you in full wolf form." This excited Stiles more than it should've, but he didn't have time to think as Derek took him and placed him on the kitchen table, dick in hand and looking at him with a smirk. "Open wide..." Stiles kept himself from moaning, but the angle was just hitting his prostate aggressively, making Stiles cum so fast he felt ashamed. "I didn't know you want my wolf cock so much..." Derek growled playfully as he pulled Stiles into a hug, dick still inside him, Stiles' legs still wrapped around his waist as he lowered himself to the kitchen floor and laid Stiles there: "Well, i told you, didn't i?"
Stiles gasped when he felt Derek's body shift, the white fur that grew on his body, the teeth that grew, the tail that barely appeared and was already wagging, and the dick- Oh my Gods, the dick- It felt so fucking good, it grew with his wolf body, the looong tongue that licked his face as he moved his waist, pushing the wolf dick further down his body, Stiles couldn't do anything but moan as his body instinctively adjusted to the ravaging, restless, throbbing dick that made him almost faint from so much pleasure- He couldn't cum anymore, he wws sure he was crying, but the knot entered his ass, pushing against his entrance as a thick liquid bursted inside his ass and the howl followed by the bite on his shoulder. The pain of the bite, the pleasure of the cum, the bulging of his stomach as it was filled with thick loads of cum, he couldn't help bur cry as he also cummed.
Or at least he felt the pleasure of cumming, of having an orgasm, but nothing came out.
He was confused by this, but the wolf did not stop because he knew Stiles was still not full, so he kept going, thrust after thrust, like a bitch in heat Stiles couldn't stop moaning: "Derek! Oh Gods, harder, faste-" but his cries were met with deaf wolf ears as the big bad wolf himself kept fucking him with gusto. He lost time of how many times he felt that rough thrust, but when he came back to himself he and Derek were on the bed, Derek still thrusting him, he was tired so he just laid there almost unconscious, driven mad by the dick his husband- of course he's gonna call him husband after all those thrusts, how could he not call him husband?- so eagerly used to please him, annaly, oraly, damn, he even fucked his thighs, hands, and even feet. He bit and marked every single part of Stiles' body, he was completely covered in Derek's overflowing cum, he smelled just like him.
And he loved it.
When it was the 8th day, one day after his Rut ended, Derek was groggy. He felt a painful throb on his dick, it felt so raw and hot, then he slowly and tiredly opened his eyes and looked at the man below him, Stiles was naked, in fact both were, but Stiles was completely full of bites and hickies, he could see how red and swollen Stiles' ass was, his eyes widened when he saw the claw marks on his Mate's body as well as the bulge he had, still inside his poor wrecked body was Derek's dick- "Ahn..." With a soft moan, Stiles moved his hips and Derek felt a tinge of pain and pleasure on his dick, he used it too much- Then, memories of how many times he fucked Stiles, when he fucked Stiles, where he fucked Stiles, and in which and how many positions he fucked Stiles, and even in which forms he fucked Stiles.
Human, Beta Shift, Alpha Shift, and even Full Wolf.
He winced when he smelled blood and saw dried blood on the sheets, he whined sadly as Stiles opens his eyes slowly, looking at him. "Mmm... G'day Sweetwolf... Wildwolf, Sexywolf, Roughwolf, Destroyerwolf, Killerwolf, i am just going to keep calling you wolf names until you say something to me." Derek cringed at the smile Stiles gave him, guilt overwhelmed him as he closed his eyes and said:" I'm sorry."
"Never." Derek opened his eyes and stared at Stiles, who just rolled his eyes at him, saying: "Never apologize for making me feel good. Okay? Never. Unless i ask you to stop, you don't need to stop, because i enjoy whatever you do to me." Derek gulped down as Stiles' stared intently at him, slowly but surely, a smile blossomed on Derek's lips as Stiles touched their foreheads together, saying: "I love you, dear."
"I'm love you too." Derek smiled weakly.
"Now... Get your dick out of me."
Derek chuckled, and he did so.
