Finish what you started

From Torg Adventure

As much as you'd like to leave your sister the frustrated one for a change, you'd be left at least as bad off if you stopped now. So you just keep driving your cock in and out of her.

"That's it, Max," she coos, her anger fading to make room for more arousal. "Just keep fucking me... we're almost there."

You feel her pussy squeeze your cock rhythmically. "Yes, Max, fuck me good... fuck your slutty sister, and make her cum hard..." Her feet shift slightly on the slippery shower floor, as she adjusts her position against your thrusts as best she can in her current position. "I promise no more cock-teasing, just screwing like this." She chuckles a little bit. "Maybe I'll even skip the pill for a few days, and give you better odds the next time around. It just wouldn't be right if I let our amateurish sisters get preggers before me, would it?"

She moans loudly, and her wrists wriggle under your hand, but do not come loose. Maybe she was going to try to put them around you, or something like that, but for now you like her in this current position, as you still don't quite trust her.

"In fact, I'm not sure that I took my pill this morning," Lisa continues in a husky voice. "I'm horrible about remembering that kind of thing, which is why I usually use condoms anyway. I'm so terribly irresponsible, Max. Honestly, it may have been a couple of days since I took the pill..." She moans again. "Max, slow down lover, just for a little bit. It's like the idea of me not being protected makes you more excited." She says that with a straight face, but you know that, now that she's finally given you her pussy, she's found something new to tease you with. You slow down a little, working against the urges her words had just incited in you.

"Yeah, just like that, Max," Lisa says approvingly, her voice just above a murmur. "I won't talk any more about how I might be totally unprotected right now, because I don't want you to pull out until you fill me with your baby-makers. I've been making all my guys wear condoms lately, just because I've been screwing up taking my pills, and I really miss the feeling of cum filling me up...

"So please promise me that you won't pull out, Max, even though I am so fertile right now, and might not be protected." Lisa looks at you in feigned consternation. "You won't do that, will you Max? I don't want you to be scared by the risk of knocking up your sister with your incestuous baby..."

You know she's just playing mind games with you, but you can't help but be even more turned on about it. Her words are ensuring that the last thing you want to do is pull out before you fill her with your seed, even if you are pretty certain she's lying about not taking the pill. Just as always, she's leading you on, letting you think you're going to get what you desperately want, even if the stakes had radically changed. You were fucking her now, but now she was dangling the possibly of impregnating her as a lure.

"Okay, faster please, Max." Lisa begins bearing down on your cock harder with her pussy. "As much as I like getting fucked, I like cumming even more. I want you to fuck me harder and harder now, until you give me a big creamy load, as deep in my pussy as you can." She begins to breathe harder as you fulfill her request and increase the urgency of your motions. "I hope you still have some cum left after Amy and Sam, Max. You'd didn't use it all fucking them last night, did you? I'd be a little jealous if they were getting all of your sperm, because I know I must be a much better fuck than them."

Her body writhes against you again. "Yeah, even harder Max. I'm... almost there... But I'll try not to let it happen until I feel you start filling me up. Just don't make me wait too long, Max. I really need to cum... and feel your cum..."

Her talk about you cumming inside her was working to bring the moment even closer. You drive into her one more time, actually making her feet slide back a little on the shower floor, and almost jarring her wrists loose. It feels for a moment like the entirety of your essence is suddenly collapsing into a singularity centered in your groin, before suddenly being released into Lisa's twitching pussy.

"Fuck Max, that's it!" Lisa's voice wavers as she feels your cum shoot into her. She throws her head back, actually hitting it against the shower wall, but that doesn't seem to affect her rapture at all as her cunt spasms around your cock hungrily. "Cumming... so hard... ohhhh..." Her body slumps a little, but you keep holding her up by her wrists and by wrapping your free arm around her waist.

"Yes, don't let me fall," Lisa gasps. "Hold me here and keep cumming in me! It's so hot and I want more of it filling up my cunt, Max!" You erupt again, and feel her cum again as you do so. Or maybe it just turns on the intensity on her current orgasm. Either way, she seems to be having an extremely powerful orgasm, and the more cum you pump into her, the more powerful it seems to become. And the more you see of the effect your spunk is having on her, the more of it you seem to spill into her.

You finally let go of her wrists, taking her in your arms as she collapses weakly against you, her body still twitching as an aftershock hits her body. Her arms go around you, to help support her body, and to try to pull her closer to you.

"Damn, little brother..." Lisa struggles to catch her breath. "You didn't hold anything back. I don't think I've ever had this much cum in me ever. At least from just one guy. Our sisters aren't doing a good enough job of making sure your poor little balls are properly emptied." Apparently regaining some strength in her arms, she succeeds in pulling herself up against your body, her tits pressing against your chest. She puts her mouth against your ear, so that you can feel her hot breath on it. "Or is that just all the cum you've been saving up since I first started getting your dick hard? That would be like over a decade's worth of cum."

She nibbles your ear a little. "I'll bet that's it. All that teasing over the years created a huge backload of baby-makers in your body. If that's true, I'll bet you've got even more than that stored up. Poor little Max... I owe it to you to help you get that all out of your system. All that cum stored up can't be good for you... but I'll bet it will be good for me." She pulls her head back to look you hungrily in the eyes. "Because if you play your cards right, you're going to find out just how much of a cum-slut your sister is."
