Play Stupid Games, Win Stupid Prizes (No, he doesn't)

He thought about what she said, rolling it over in his head, before coming to a decision. He promised he wouldn’t hurt her. He hadn’t expected what would have happened but… he had some changes to make now.

“One second, Bree. I’ll fix this” he said, pulling out his notebook from the aether and jotting down a few more rules.

She didn’t see him do it, of course, but she did notice when her belly felt immediately better, less strained like a tight balloon. It felt good, actually, a sigh escaping her lips at the released tension. But when Sam started rocking his hips again, she couldn’t hold back the shameful whimper from her sensitive insides.

“Sam, w-what are you–“

“I still need to cum one more time tonight, remember? Course, you did say I could do whatever I wanted, so I might just cum a few more times while I’m here. Gotta fill you up, Bree. You need to be ready to have a baby. My baby.” She hissed as he pulled out nearly all the way, before sloooowly hilting himself again.

Leaning down to whisper into her ear, Sam reminded her, “A whole month of this, every day. You’re gonna be draining my balls just like this and cumming on my cock every time. I’m pretty sure I won the bet too, so I get to decide how and when we do it from now on. Are you excited Bree? I know I am. I know my sister wants a big family, and we are twins, so maybe you’ll get lucky with twins of your own. Maybe even triplets. They’d be so cute Bree. So just lay there and take my cock while I fucking breed you for the next month.”

He started moving in earnest, not letting her form a response beyond more moans from the supernatural sensations he was giving her. No matter how hard he thrusted, she felt no pain, only more of the same pleasure as before.

Even more importantly, he didn’t feel the need to hold back for fear of climaxing anymore.

New rule: Male twins can control when they ejaculate.

Sam could go almost as long as he wanted now, taking all the time in the world to feel this woman be pushed past the brink underneath him. At one point, Sam pushed off of Bree, sitting up and tilting her ass up with his. Then he wrapped his hands around her waist and he savagely thrusted into her, watching as her tight pussy seemed to get dragged out by his girth (just a bit) every time he pulled back. Then he’d push back and he’d see his cock going as deep as it could possibly go. Then, at the end, he would feel his glans press on the final barrier to Bree’s womb. Seeing her toned, womanly, hot Latino body bent ass first on his cock, feeling himself fill her insides to the limit, and knowing he could do this as many times as he wanted now… it was the best feeling ever.

This position also had the benefit of letting Sam finally see Bree’s face as he fucked her, or at least the half of it that was turned to the side. Her eyes were shut tight, trying her best to hold back the tears. She still couldn’t hold back the noises, though, and they were what made it all worth it. She hated him, he knew, but seeing her unable to stop herself because his cock was too much for her to handle… it felt deeply satisfying to watch. Addicting, even.

He idly felt regret for not being able to see the moment when he’d first penetrated her, but there were other things he would be able to witness. Like how she would react to the last two rules he’d written down.

New rule: A male twin’s ejaculation will enter and stay inside a woman’s womb upon release for up to four hours after semen enters it, shooting past the cervix without causing pain or damage to it or her womb.

New rule: A woman’s womb will pleasurably and safely stretch to contain all of a male twin’s ejaculations.

Thinking about it after Bree’s pitiful pleading, Sam had realized cumming so much could be a problem, namely make an awful mess, so he decided to take care of it another way. He wanted Bree to take everything he had tonight, to never forget what he could do if she pushed him any further. Thinking of his sister, Sam at least promised himself he wouldn’t be quite so rough in the future… unless she deserved it. He was going to teach her respect if he had to fuck her brains out to do it. But before he really did that, Sam wanted to change positions again.

Taking advantage of Bree’s well-trained, flexible body, he took one of her limp, mocha legs and brought it up to his chest, twisting her to lay on her side. The change in position, amazingly, allowed him to get even deeper into Bree’s spasming cunt. He was practically scissoring her (ironically), his groin as close as it could possibly be to hers. The extra inch of cock inside her was almost too much, knocking the wind from her lungs as Sam rocked his hips against her battered sex. She couldn’t take much more and they both knew it, so Sam decided to finally end it.

As if pulling a hidden trigger in his mind, Sam allowed his building orgasm to come forth. It was just as good as the last time, better even. He angled as best he could to unload directly against Bree’s baby-maker, giving her everything he had and delighting in the shocked, mindless pleasure coursing silently across his lover’s beautiful face. She didn’t make a sound though, the room only filled with Sam’s grunts and groans. Apparently her voice was simply broken now.

Her body spasmed as she squirted again, this time splashing warmly against Sam’s clenching thighs and stomach. He watched her abs clench, her hands gripping anything in reach, and felt her strong thighs twitch against him. She was totally helpless while his cock pumped more and more semen inside her. Tears came down as the truth started to sink in. Somehow, her body was unable to control itself from whatever this was. She would cum on his cock every time he came into her, the shame coursing through her body as much as his semen was.

As he was finally petering out, however, Sam’s animalistic urges overtook him, begging him for more. For better or worse, he had given himself the ability to trigger his own orgasm whenever he wanted to… and was certainly convinced to do it again.

So he repeated the process, Bree’s barely relaxing body grew taut as a bow once again, as another overwhelming orgasm was **** onto her. This time she could only let out a weak trickle of fluids from between her legs, but the indescribable feelings remained as she endured both the climax and being packed full with even more of this horrible man’s impossibly thick cum.

It was different now, Bree could feel it, somewhere through the strange fog clouding her mind. Before, she’d felt incredibly uncomfortable in her insides, unnaturally filled as she’d been. Now, it felt… amazing, like her body had been made for this, to be filled again and again until… she was pregnant. That was her last thought before succumbing to the darkness, falling limp as Sam once again started coming down from his high. Without hesitating, he came again, emptying what was left in the tank till the end. She didn’t react this time. A single shudder perhaps, her dreams filled with haunting sensations, her belly growing from the child she imagined having with her one true love.

Back in reality, Sam was finally tapped out, his whole body shaking like a leaf in the wind. For a first time with a woman, that hadn’t been so bad. Looking down, he breathed in wonder at the bulge from Bree’s belly. He had done that. He had filled her to bursting and then gone a step beyond. He felt… good. At peace. Exhausted. With a weak huff, Sam dropped Bree’s toned leg that he’d been desperately clinging to, flopping down behind her **** body and positioning himself to spoon directly behind her. He debated pulling out of her, giving her some much needed rest. Then again, the idea of staying inside, all cozy and warm in her innermost depths, ready and waiting to fuck when he woke up tomorrow morning… it was almost too good to pass up.
