Endless fucking V

Richard didn't hold back any bit of himself as he grasped her legs open as far as he could, taking a moment to look at how wet she was, before he leaned forward and pressed his lips against hers. She trembled at the touch of his lips and then opened her mouth to welcome his tongue into her mouth. Gone was any semblance of understanding, of being able to think coherently or make any sense of words into a sentence. All her brain could do was process the feeling of the young man's cock pressing against, and then easily into, her pussy. Vivian moaned again as she felt him slide into her without any sort of hesitation. "Oh fuck..."

He pushed as far as he could go into her, noticing with some degree of pride that there was still a few inches left out of her, before he just pulled his hips back until just about to pop out, causing her to look at him wantingly, before he slammed back into her as deep as he could go. Any complaint or beg was lost to the winds as her eyes rolled and her mouth ceased all function, just mouthing the letter "o" and "fuck". He gripped her hips as tightly as he could as he pounded into her, all control lost except in pushing his cock as deeply as it could go into the woman's body. It wasn't going to last for long as the sensations were too much to bear and he pumped deeply as possible before he felt his cock twitch and he came in her. The first several splurts of cum caused Vivian to cum and cum hard for him, her body shaking before she passed out.

Richard continued to push in and pump in more and more until he felt as empty as possible and slid out, collapsing next to the **** woman laying splayed on the floor. He looked down between her legs as the white tell-tale signs of his very young and very potent cum seeped out between her pussy lips and lay in a puddle on the floor. Each time he brushed against her reddish lips, brushed against her clit, he caused a shudder to go through her body but she lay completely still and in shock. "Holy fuck..." he whispered before he too fell asleep next to Vivian.

"And then...?"

Richard brushed his hair to the side and looked down at his phone. That had been quite the morning and after taking an hour long nap, he had gotten up and looked down at the sleeping blonde, her body still looking as youthful as ever, and he couldn't help but give her a long deep kiss. Even in her slumber, though, Vivian reacted and she moaned before he just left her there, tucked under a blanket he had found in the closet, and then left for home. He barely got back in before the parents got up and he managed to play off the rest of the morning with doing some chores around the house. It wasn't as easy as he would've liked, though, especially since a lot of the chores were physical in nature (never again would he ever complain about doing dishes, he mused, though he figured it was a small price to pay for the feelings he got through sex, that was for sure.)

"I just couldn't help it...I had to..."

His aunt's laughing on the opposite end caused him to stop. "No, I meant how do you feel? The **** you're taking impact you permanently, Richard. You took 3 already."

Richard blinked at that before he nodded and slowly sank back down to the bed. "Oh...didn't think about that. I mean...well..."

"Are you alone?"

He nodded and quickly, and quietly, closed and locked his bedroom door. Downstairs, the parents were fast asleep as he spoke but he didn't want to disturb them with any sort of call. Or the embarrassment of them walking in. That would be hard to say. "Yes..."

"You took 3 pills, leaving you with 27. You gave 4 to Vivian and she looks like a 21 year-old model, right?"

"Yeah...if that," Richard replied, the images of this morning and the sound of her moaning causing him to grow hard again. "What does that mean?"

"It means the medicine alters the state of Xchange users, namely by regressing the age of those who are physically older than you, while making them susceptible to you and you alone. I told you that they were coded for you genetically. Meant it, too. They're going to bind these women to you and their changes will fit you and your image for them."

Richard paused for a moment and looked down at his throbbing cock. "What about the pills I took?"

"Super sperm. Congrats, kid, you're living every 18-year old boy's dream."

He felt his body react to that and his cock began to throb again. "Um...Aunty..."

"Don't go and fuck anyone, Richard. You took the pills. Your sperm right now could knock out any girl who wasn't prepped to receive it. Hell, you'd get a reputation as a great fuck, that's true, but your body wouldn't be satisfied." She paused for a second. "I'm going to send you more pink pills, they should get there tomorrow morning. Don't give more than 2 pink pills to any woman who has taken XChange, okay?"

"Right...but what do I do now? It fucking hurts..."

She paused for a moment. "Go back to Vivian. She'll need you now. Give her one more pink pill, take it to 5. This will cause her to change and she'll no longer be able to function without you...but at least she'll be stable." Just as he was about to hang up, she caught him. "Oh, and Richard?"

"Yes?"

"She'll have changed again. Be ready for it, okay?"

Richard hung up and after making sure that he was dressed again and checked downstairs to make sure his parents were still asleep, quietly crept out of the house and made his way down the few houses until he got to Vivian's. The lights were off as he approached but he just pulled out his phone and sent her a text with the simple "Outside." A few moments later, the door unlocked and the light came on.
