You and Sam alone
From Torg Adventure
Before you can even suggest anything, Amy says, "Come on, Mom, you pervert. You need a shower." She reaches her hand for your mom's, who takes it and let's herself be led out of the room. You wonder if Amy has designs on taking a shower with Mom. Since the incest barrier has been breached, and she professes to be a lesbian, maybe she'll take advantage of Mom in her weakened state. The idea starts the blood flowing again.
Once they are out of the room, you go to the closet and open the door. Sam comes out with saucer-sized eyes and her shirt undone. The drawstring on her sweat pants is loose as well. You think she's been playing with herself.
"What has happened to this family? Suddenly we're all sex maniacs!" you sister says with surprise and a hint of lust in her voice.
"What do you mean, 'we', Sam?" you ask.
Then it's your turn for your eyes to go wide with surprise as Sam pulls you into a clinch and kisses you hard, grabbing your junk at the same time. Her tongue slips between your lips, and you both French kiss passionately.
She breaks the kiss and says, "I want to pay up now. I'm so hot and wet and horny after watching the three of you that I want your cock in me right now." Then she takes her shirt off and you see that her bra was pushed up over her tits so she could fondle them in the closet. They are really nice perky handfuls, and her nipples are fat and excited. So much for being a prude.
She takes off the bra and flings it on top of her shirt, then drops her sweat pants so fast that she takes her panties with them. She straightens as she steps out of the pants, and you see her in her naked glory for the first time. Your little brain is standing at attention.
She starts pushing you toward Amy's bed. You bump into the mattress and crawl backward. Sam follows closely. You've never seen the animal need in Sam's face before. It was like someone had flicked on a light switch. Your body lights up with pleasure when her hand caresses your cock again. The head of it aches to be plunged inside the warm, sexy sister before you. You get far enough in on the bed that you stop, and Sam dips her head down to lick from your balls up to the shaft, then waver playfully up your stiffness to barely tickle the head with the very tip of her tongue. You groan, closing your eyes with anticipation for her taking you completely into her mouth and down her throat.
But it never comes, as Sam keeps crawling up your body. You open your eyes to see her gazing at you with a sexual desire you've never witnessed from her. Her tongue plays along her lips, then when she sees you're watching her, she winks and then leans down to suck your left nipple, making you arch your back and moan with delight. Not only does Sam want to fuck you, she's taking some control. She's making it happen. That's very sexy, but it also means she's into it and it might happen again. You stroke her back and hair as you let her continue at her pace.
You're not disappointed when Sam switches to your other nipple, this time twirling her tongue on the tip of it while she sucked. That sends your nerves into heaven and you growl. The steel in your groin is pressed hard against Sam's belly, trying to drill through her, and when your sister moves on from your nipples, licking up your neck to kiss you again, her belly and below slide up your body as well.
Pushing herself up to straddle you, her pussy is in line with your cock. Her gaze never wavers as she slides her cunt lips up and down your shaft. "I don't know what's happened, but a flood gate has opened in my head and I can't get sex out of it. My body knows what it wants and I'm along for the ride." Just then her groin has reached to top of your shaft. As her slick pussy lips part around your cock head, her expression changes to one of surprise for a second as you feel her cherry burst on your steel flesh.
A whisper of "Oh, my," escapes her lips, as she closes her eyes and sinks down, taking an inch of you into her body. You grab her hips more securely, and at the same time thrust up with your hips and pull down on hers. You pierce deeply into Sam's cunt, filling her completely.
"Oh, my fucking God!" she exclaims. Her body starts shaking into her first orgasm with you inside her. You reach up and cup her tits, twisting and pinching her nipples as well. "Oh, Max! I didn't know it felt like this!" Sam shouts as she starts bouncing up and down on your shaft.
Her cunt feels so good on your cock, tight and very slick. Watching you fuck your sister must have gotten her crazy horny. You fondle her breasts as you watch your cock sliding in and out of her baby channel, coming out glistening with her excitement. Sam moans as she fucks you.
"I don't think I can stop after just once, Max. I know our bet was just for one time, but if I keep feeling this way, I'm going to need more of your cock. Aaaaaah!" Sam moans into another hard orgasm, and you can feel her muscles pulsing on your stiffness inside her. Her whole body shakes with the power of it. Then she speeds up her bouncing. You thrust your hips up as she comes down, and the collision ripples up her body to wobble her modest tits. You start imagining Sam doing this when she's several months pregnant, with a big round belly and bigger boobs from the hormones. Then you get an image of that, plus the very pregnant Amy and Mom pleasuring each other as they watch. Sam straightens up more and drives up and down like a piston. Your imagination shifts and now Keiko and Lisa are in a Sixty-Nine next to you and Sam. Amy and Mom moan out their voyeuristic joy.
"Is your mind drifting, Max? You got an interesting look on your face just then. Are you imagining Mom and Amy watching us? Does that turn you on even more than fucking your sister? Oh, God!" Sam goes even faster for a few strokes, before saying, "Oh, God! That makes me so fucking horny just thinking about it!" She leans down, trapping your hands between her boobs and your chest. She kisses you wildly, her tongue exploring deeply in your mouth. She breaks the kiss and whispers in your ear, "I wish I'd come out when you were fucking Amy. Then it would be reality instead of a fantasy." She resumes the deep French kiss.
You want to really pound the Hell out of Sam, so you roll her and land on top. She spreads her legs wide and then up. Sam's very flexible from her martial arts training, almost like an acrobat. "Oh, Max! Fuck me hard! Make me come all over your amazing cock!"
You hammer into her like crazy. If you hadn't just fucked several times in a row, you'd be exploding sperm inside the third family member today. Sam's back arches and her body shakes like San Francisco during a quake. You feel her strong pussy muscles beating against your invading cock. She keens up into a high register wordlessly.
Sam, in almost a whisper, says, "Oh, yeah. I know what's next. Give it to me. I wanna feel you inside me all day. Come in my sweet pussy. Fill me!"
With that and her climaxing cunt on your cock, you can't hold back any more. You growl loudly as your cock erupts like Krakatoa, spewing your hot jizz deep into your sister. You hold yourself as far into her pussy as you can as your balls pump more and more in her.
"Yes! Oh, Max! It's so hot and good inside me! I can feel it way up in me. So hot!" Sam's body keeps coming and you keep filling her, until you both slump, your bodies spent. You cock is still hard inside Sam. Occasional aftershocks squeeze you. All you can hear is your breathing.
Sam is the first to recover. She caresses your hair and back. She gives you little kisses on your cheek. "That was amazing, Max. Thank you for making that happen."
What now?
