"I like the threesomes a lot, but having time with each of you would be great," you say, sliding your arm around Lisa's waist. Amy cuddles into your other side, kissing your cheek. "As long as we don't stop the threesomes, I'm game."

Lisa says, "Oh, believe me, I don't want to stop them either, but a girl needs some alone time ... with your cock."

Amy says, "Just fuck each of us, then more threesomes! And maybe when Sam realizes she's lost, we can have foursomes!" Amy has always been the optimist. 

"Okay, so I'm going with Lisa first, then I'll visit you, Amy. You'll each get your alone time with me before tonight, even if Sam doesn't sleep long enough for both of you," you say, having trouble keeping the wide grin off your face. You have a jackpot situation here, seeming to have won the sister-fucking incest lottery.

"Okay," Amy says, "I'll be ready for you!" She heads downstairs, probably for food.

Lisa looks at you with a hungry stare, her pink tongue licking her lips.

"Oh, Max. This is gonna be great!" she says, taking your hand and pulling you to her room. Once inside, she locks the door. You spin her around and press her against the door.

"Max, my cunt needs your cock in it, and my womb needs your junk. Do that now, and I'll do whatever you want. Unh!" she says, moaning that last because you slammed your cock inside her very slick pussy. "Anal, tit fuck, I even like a little rope bondage from time to time. Oooooo! Fuck your cock feels good." Your buxom sister grinds her hips down on you, squeezing her inner muscles around your cockhead. had 

You bury your head between her enormous boobs, and she pushes them together around your face. You motorboat her and she laughs. In the corner of your eye you can see her pinching her nipples. You pull out and attack her left nipple, sucking it hard and chewing a little on the end. Lisa moans, then squeeks when you add a bit more pressure. 

"Oh, Max! Fuck me as hard as you want. I like it rough. I have trouble finding men who can keep up with me, but I'm thinking you just might. Unh, fuck you feel good up in me," Lisa says, her voice trailing into feral grunts as you pound her cunt with hard, steady thrusts. You switch breasts and twist the nipple you just finished sucking, as you bite the other nipple, hard enough to make her squawk. Her next groan was deeper and more erotic than before. 

"Oh, God, your teeth make me so wet. You can bite me anywhere! Fuck! Max!" she shouts as you nip at her soft titflesh and then her neck. You're still stroking quickly in and out of her slick pussy. Her heat radiates your shaft, warming the thick blood within. 

When Lisa pulls both feet off the ground to wrap them around your waist, you start going much faster.

Lisa groans as her body begins to shake and you feel her cunt squeeze you, pulling your junk out. You gasp as you fill her with surging cum. 

"Oh, God! Yes! Your cum feels so good. Fill me, baby!" she shouts as you grunt and cum. She kisses you, squeezing her cunt around your meat. 

You finally come down and she puts her legs down as you slip from her slick furnace. 

"I just can't get enough of your cock. Who would have thought my brother's cock would be the one to satisfy me?" she purrs in your ear.
