Chapter Text
Ben and Gwen had been in a trip with their parents. They had stayed in a nice hotel, with the parents having decided to have the cousins share a room.
With him being a reincarnation of a massive nerd from another Universe that masturbated several times to Gwen, and her having a massive crush on her cousin, the sexual tension was cranked up until it snapped and the two jumped eachother.
“This is so wrong.” Gwen softly mumbles, biting back a moan as Ben keeps kissing her neck while rubbing his fingers over her crotch.
“Do you want me to stop?” Asks Ben, whispering it on her ear, causing her body to shiver in response.
“...please don’t.” She begs, her face flushed red.
Ben smirks and begins pulling off her clothes, leaving her hyperdeveloped 10-year old body naked for his eyes.
His cock ached inside his pants, so he let humongous shaft out, making it fall on and slap against her pussy, earning a gasp.
God, you’re beautiful. You see this, Gwenny?” he asks, referring to the dick he was currently grinding against her pussy. “This is because your lewd body made me aroused. Isn’t it cool?” he asks, grinning.
“B-Ben, please...” Gwen whines, her pussy already dripping wet.
Hearing this, Ben wasted no time prodding his lower head on her entrance until it pierced through and penetrated her insides.
Gwen let out a brief loud moan before Ben covered her mouth.
“We don’t want anyone, especially our parents, stopping our fun, do we?” says Ben, slowly moving his hips back and forth.
Gwen’s moans are muffled, but she nods rapidly.
Smiling at her cute red face, Ben picks up the pace of his thrusts, intending on reshaping her pussy in his cock’s image.
Her tits bounce up and down from the force and speed of his thrusts, and Gwen couldn’t help but feel herself blanking out.
Ben, on the other hand, had foregone being delicate and was now fucking her like an animal, having moved the both of them into a mating press.
Time passes, and the only sound it could be heard from the room was the rapid clapping from his flesh meeting her's.
All good things must end, and Ben found himself getting closer.
“Oh, man! I’m close! Get ready, Gwen! I’m cumming!” he declares.
Giving out the last few quick thrusts, Ben sheathed himself fully into her and lets out an excessive amount of cum that you only see in porn.
Ben pulls out and lets his shaft burst it’s last load on her tits and face.
Falling to her side, Ben releases an exhaustes sigh.
“Man, i needed that. Was it good for you, Gwenny?” he asks her.
Earning himself no response, Ben looks at her to see that she fell unconscious from pleasure.
Sighing to himself again, Ben activates his Omnitrix and prepares to clean up the mess by himself.
“Hey, Ben? What are we?” Gwen asks Ben, the two laying naked on his bed, with her on top of him with her head on his chest.
“Cousins. I thought you knew that.” He jokes, earning him a slap to the chest.
“I’m serious, Ben! I...I like you. A lot. And i don’t want to just be....a memory.” Gwen confesses.
“I care about you, Gwen. Could even say that i like you as well. But i don’t really like the idea of...being stuck in a relationship. I like the idea of going around, meeting new girls and having fun.” Responds Ben.
“I don’t mind that. I don’t care how many girls you get with. I don’t care if you have a damned harem. I just....I want tonight to have meant something.” Says Gwen, tightening her embrace with you.
“All right then, deal. You are officially my first girlfriend, not that anyone is ever going to know that, but i’m allowed to date and have fun with other girls. In return, i promise to shower you with love, affection and pleasure.” Ben tells her.
“O-Ok! Girlfriend, huh? That...makes me happy.” She smiles brightly.
“Then you better get ready.” Says Ben, getting on top of her. “Every harem has it’s top girl. I expect no one else but you in that position. For that, i’m going to mold your body and mind to be the perfect match for myself.” Declares the boy.
“U-Um....Ben, are you-“ she is interrupted by his dick once again between her folds.
“This is non-negotiable, Gwen~” his eyes glow a dangerous green as he begins using her once more.
Neither of them slept that night. Despite the exhaustion the next day, neither minded.
