"Stiles what are you doing? Are you crazy? Your mom is right there?" Derek stressed as he glanced over to his stepson, standing by the side of the bed with his hand under the covers, rubbing his cock, awakening the sleeping beast.

"I need your cock, Daddy," Stiles replied eagerly, with desire in his eyes and a playful smile on his face.

"Fuck." Derek gasped, before glancing back at his sleeping wife and then back to her son, tossing the covers to the side, letting his growing cock breathe.

"Get up here and be quiet about it."

Stiles who was palming his own growing problem, quickly slid his boxers off and got on top of his stepfather's lap, spitting down on his cock, getting it nice and wet before guiding it into his needy hole.

"Ohh." He moaned out, as he slowly slid down on Derek's monster length, letting it fill him up and stretch him out.

"Shush, quiet. You don't want to wake up your mom, do you?" Derek whispered, glancing between the two, worried about making any wrong moves that might awaken her.

"No, but uhh, it feels soo good." Stiles voiced, as he rode his stepfather's lap, moving his hips up and down with his hands resting on Derek's hairy, built chest in support.

"I know baby. Fuck, I know," Derek replied, unable to hide his desires as he closed his eyes and grabbed onto Stiles's ass, giving it a squeeze, and began thrusting upwards.

"Fuck me harder Daddy. I want to feel you deep inside, rubbing my insides so good." The teen moaned as he sped up, overtaken by pleasure.

"Fuck Stiles, your mouth is so dirty. I can't control myself when you talk like that." Derek confessed, reopening his eyes, and watching his stepson ride him. He grabbed onto his slender hips and began to thrust deeper, harder up into his ass.

"Ohh yeah, like that Daddy. Don't stop," Stiles stressed, biting his lower lip.

"Not so loud, do I have to cover your mouth?" Derek teased.

"Mmm, Derek, do you feel that shaking?" Claudia asked groggily through closed eyes, still asleep.

"Wha uh, babe, I was just uhh, getting water. Go back to sleep." Derek stressed, trying to lighten his thrusts, and even out his breaths to hide the action taking place on the bed.

"Ok, dear. Love you." She replied sleepily, before drifting off to a deeper sleep.

"Ohh, umm, love you too," Derek claimed before returning his attention to Stiles who was completely unphased by what had occurred, still moving on his stepfather's hard and now wet with precum cock.

"We can't do this here," Derek whispered.

"Don't stop Daddy. Please, I'm close."

"Uhh, fuck." Derek groaned out as Stiles picked up speed.

"Babe?" Claudia voiced, moving around in bed before opening her eyes, and seeing the sight of her son riding her new husband.

"STILES?! DEREK?! What the hell is going on?!" She shouted, sitting up in bed and turning the lights on in horror.

"Fuck!" Derek exclaimed in surprise.

"Uh, we were just horsing around." Stiles lied.

Derek rolled his eyes at his stepson's lame explanation.

Seriously Stiles, horsing around, naked with my dick buried in your ass?"

Claudia gasped.

"Well, I don't see you coming up with anything," Stiles argued.

Suddenly a heavy thud filled the room.

"Mom?" Stiles questioned, seeing his mother passed out on the floor.

"Ah, fuck it." He voiced before starting to bounce on Derek's cock again.

"We are so going to hell," Derek claimed as he picked up speed and started slamming his stepson down roughly on his achy cock.

"I'm too close not to get off. We'll deal with the repercussions later. Fuck Daddy, right there!" Stiles replied, leaning back, and rolling his eyes into the back of his head.

"Uhh, I'm cumming!" Derek stressed, holding onto the teen tightly as he pumped his cum deep inside.

"Me too! Ah!" Stiles exclaimed before collapsing onto his stepfather's form, exhausted.
