Collaborative sex stories let us write the plot together

(Medical Experiments, continued by Diesel...)

Well, this certainly is an amazing afternoon. You feel like a total perv but hey, when else could you ever just have your way with so many women? You slide into the seat behind the sorority sisters and listen in on their conversation.

“Oh my god, did you see Brad waiting around in the hallway? I could see a big bulge in his pants. I think he is totally banging Kelly. When they left the bar last night I am sure he had his hand up her skirt. He was probably finger-banging her as they stumbled out!” The gossiping girls don’t realize that they are visibly squirming as they talk about the dirty deeds of their friend, and they certainly don’t realize you are listening in.

When their stop comes up, you meander off the bus right behind them, following so close they each turn a few times wondering if someone is there. One says, “I can’t wait to get back to the house and lay out by the pool!” and the girls pick up their pace, scurrying up the driveway and into their sorority house. You slip in close behind…

The girls slip off to their bedrooms to change into bikinis and meet back by the pool. You follow one to the closest room. After all, they’re twins, so pick one, right? As she slides her plaid skirt off and then her lace panties, her beautiful shaved slit is exposed. You start to rub your crotch through your pants as your wood begins to grow. You find yourself wondering if the other is shaved down below as well. It takes all your willpower not to just grab her then and there when she takes off her shirt and bra, setting her luscious little melons free. Perky, nickel-sized areolas. Tight, tiny ass. Damn.

She throws on her bikini and jaunts down the hall towards the pool. The other girl is already outside, her perfect tits and ass barely contained in her tiny swimwear as she oils up with suntan lotion. Her eyes are closed and she has her back to you when she calls out, “Will you spread some oil on my back?”

The first girl has slipped in the pool so you see your chance. You reach out as gently as possible and make contact with her glistening skin, spreading tanning oil across her shoulders. “Oh Allie, that’s nice!” she purrs. You can see her start to squirm again… these girls are sexually charged!

As Allie comes over to see what’s going on, you’ve can’t hold off any longer. You reach up and yank off her bikini bottom, smacking her ass with a loud spank. “Hey!” Allie yelps, thinking her sorority sister did it!

“What?” says the first. Grabbing the bottomless Allie, you bend her over so her ass is inches from her twin sister’s face and start to spank her. “What the fuck is going on? Annie, help!”

“OMG, it’s just like that girl on the bus!” exclaims Annie, remembering the skull-fucked redhead from earlier. “I am not missing out on this!” she exclaims as Allie sprawls across her oiled up body.

In no time at all the girls are both naked, your hands groping their slick bodies. Turns out Annie’s bush is well trimmed but not shaved bald like Allie’s. One hand squeezes Allie’s little bum while your other starts to work Annie’s pussy. As you flick her clit back and forth, she immediately stiffens up and moans. Her cunt is glistening as her juices start to flow. Taking the hand that’s been massaging Allie’s backside, you slip a finger into Annie and get it nice and wet. Then it’s right back to Allie’s ass as you poke the tip of your slick finger right into her little butthole.

You’ve never felt anything so tight and you immediately decide you are fucking that brown eye. Dragging her back on the lounge chair, you line up her face with her sister’s snatch and push Allie’s head into Annie’s little pubic patch. She doesn’t fight it and instead starts to tongue-fuck her, going to town while rubbing her clit.

This leaves her exactly where you want her, so you grab the oil and squirt it on her backdoor. Spreading her cheeks with your hands, you slowly push your huge throbbing member past her sphincter, pausing for a bit when she cries out. You can see her anal hole clinching around your cock, the tight skin flexing around your meat. Slowly you begin to work it in and out, this time eliciting only moans from Allie. You’re not gonna make it long, this you know.

With a few hard drives into her butt forcing her tongue up Annie’s twat, you hear Annie call out “I’m cumming! I’m cumming!” as she starts to buck. It’s too much for you so you hammer it home one last time, keeping most of your length up Allie’s ass as you unload. Pulse after pulse of ball-shattering splooge courses up her tailpipe, filling her rectum. It’s so tight and her ass is so full that semen squirts out around your cock.

As you pull out, the creampie is so massive that it’s like a river pouring out of her puckered button. You step back to admire your handiwork as the twins collapse into each other, your seed spilling out between them.
