Sam leaves
From Torg Adventure
Sam gives Lisa a withering look that would kill. Then she looks at you, but can't manage to look angry. More like wanting, wanton need. But it lasts for only a second, and not long enough for Lisa to notice, before Sam grabs her red dress and runs out of the room.
"Well, I guess you get to have sex with me all night long, Max," Lisa says, a smug look on her face. "I thought surely that Sam would cave in and beg to be fucked and bred, but she must have found some reserves while you took her ass. She did really enjoy that, no matter what she says."
You don't say anything, but close with her and embrace and kiss her hard. You plunge your tongue past her lips and run a hand up to squeeze her huge tit.
Lisa moans into your mouth and then breaks the kiss, saying, "Oh, fuck I get horny making other people have sex." Then she kisses you and jumps up to wrap her legs around you. You catch and carry her to the bed and lay her down. She strokes your cock, getting it very hard.
You break the kiss and roll Lisa over, putting a little force behind it. "I need your ass now," you say with a growl. Forcing Sam into anal really tripped your trigger too.
"Oh, Max! I was hoping you'd take my backdoor!" she exclaims as she gets up on all fours, swaying her butt enticingly. "Or do you want me to resist, like Sam did? I could tell that really got your motor running." Then she clears her throat and says, "No, Max! Not my ass!" Her tone is very close to Sam's just a few minutes ago. "It'll hurt!"
A surge of blood hits your cock and your libido spikes. You grab Lisa roughly by the hips. She whimpers convincingly.
"No! I'm saving myself! You're my brother!" she says as she tries to move away from you.
You pull back, digging your fingers into her ass firmly. Now, you press your fat cockhead against her rosebud. You're still slick with cum.
"No, leave me alone. I don't want you up there?" she says. She moves to the side, dislodging your cock from its target.
You growl, "Then let's put it where it belongs, in your cunt! Let me knock you up!"
"No, Max! Not that!" she whines. Not a bad performance, and not a bad impression of Sam.
Then you get your cock back in place and press into her. She mock-struggles, moving her hips in a way that totally stimulates you, rather than getting you away from her rosebud. You push harder.
"Noooo! Maaaax!" she shouts as your fat head pops inside her rectum. A shudder runs up her body and her spincter squeezes you.
"I have you impaled on my cock now, and you can't get away. Now, sit still and take your medicine!" you say, then for added emphasis, you slap her ass. Lisa gasps for real, and she squishes your cock again. Lisa likes it rough. You thrust hard into her, and she groans as your shaft surges forward, deep into her channel.
"Oh, it hurts. Stop. Stop." Her panting and moaning gives away her enjoyment. Her roleplaying is very exciting.
You curl your lip and speed up fucking Lisa's tight ass. She stops talking, and just moans and gasps as you fuck her. You've come twice in rapid succession, so you're not worried about going too soon.
After a couple minutes of reaming Lisa's pucker, she says, "Oh, Max! God, you feel so good in my little ass! Why did I try to stop you! This is amazing!" Still, her impression of Sam is good. She pushes back into you on each thrust forward.
Now, you're fucking Lisa's ass as fast and hard as you fucked her pussy. She can really take it well and seems to be enjoying it immensely. Suddenly, Lisa screams into the pillow and her nether hole bears down on your cock, throbbing, as she climaxes hard. You roar over her back as you spout hot cum deep into her bowels, filling her just as much as you filled Sam, meaning a large amount. Both your bodies jerk and shake as you mutually orgasm. Thoughts leave your head as the only thing left is your release.
Then you collapse onto the bed on top of Lisa, your cock still lodged in her butthole.
"Oh, Max. I really love your cock in me. I'm glad we finally did this," your sister says, panting hard to recover much needed oxygen. She's no longer pretending to be Sam. "You know what you're doing and the incest taboo just makes it all the better."
Then you drift off to sleep. It's been a long day.
What next?
