You don't mind sharing her pussy

"Sure, I'm up to try anything," you tell Lucy without looking at the others.

{if SlutScore > 30}
"We know," say James, slightly sarcastically, triggering a chuckle from Tom and Dale.

Lucy climbs up fully onto the sofa, her knees straddling you and her large breasts at face level.

"They're just jealous of how sexy my amazing little slut is," she says, pulling your face tightly into her breasts.

She lowers herself down, on the way planting a deep open-mouthed kiss on your lips, and soon is on her knees in front of you, an excited smile on her face. She undoes your belt and tries to pull off your pants, and you lift yourself up a bit to help. She does the same with your {if hasThong == false}underwear{else}bright-red thong{endif}, leaving you naked from the waist down, erection hanging in the air. As you take off your t-shirt, you feel a familiar warmth on your penis, and by the time you are able to look down, Lucy has wrapped her lips around your cock, sliding up and down your shaft a couple of times before releasing you.

"Just teasing you a little," she says with a smile.

Lucy turns herself on the couch to face you, putting one arm around your shoulder, and the other grabbing your crotch as she leans in to whisper to you.

"You've become an amazing little slut, and I love it," she whispers to you, before biting down lightly on your earlobe in response to the twitch of your cock, pulling back so as to gently graze it between her teeth before it is released.

Lucy pulls up your T-shirt, and you raise your arms to help her remove it. Next she undoes your belt, and opens your pants; you quickly lift yourself up a little so that she can pull them down, along with your {if@ hasThong == false}underwear{else}bright-red thong{endif}.

She stands up, reaches under a side-table and pulls out a bottle of lube, squirting a large blob onto her fingers and reaching down to lube herself up. She takes a second squirt in the palm of her hand and rubs it all over your erect penis, before standing up and climbing back onto the couch, this time straddling you, facing away.

"I know that reverse cowgirl is a silly porn position that isn't great in real life," says Lucy, "but want so much to see two cocks inside me."

She grabs your cock and guides you inside her, and you feel a wonderful stimulation of your cockhead as it slides into her tight pussy, overtaken by a feeling of warmth and wetness as her ass presses against you, stopping you from penetrating any further. In search of that initial wonderful feeling, you press your hips into Lucy, squeezing her ass tightly against your body until her pussy reaches the base of your cock. Bottomed-out, you pull back, receiving another short moment of pleasure until you must once again stop before your shaft fully leaves her. You repeat the process, this time feeling Lucy press herself into you as you penetrate her, and begin rhythmically pounding, focusing on the sensation of your cockhead sliding through her pussy, and her thick, curvy ass against your hips.

"Ohhh...yess..." Lucy moans, before collecting herself. "Who else wants to join us? Just lube yourself up and get inside me...my pussy will be so tight!"

The other three watch Lucy's breasts bouncing up and down with each thrust, and your cock sliding in and out of her, until finally Dale snaps.

"Alright, I can't just sit here and watch anymore," he says. He gets undressed and slathers his cock with lube, before sheepishly approaching the two of you, unsure of what to do.

Lucy stops moving, and you follow her lead. She spreads her legs further, opening a gap between hers and yours.

"Get on your knees between us, and try to squeeze inside me."

Dale does as she says; he climbs onto the couch, his legs squeezing yours together, and his cock resting on your well-exposed scrotum. In an attempt to get closer, he grabs Lucy's legs below her knees and raises them until they reach over his shoulders, slightly reducing your penetration but pressing her harder against your chest. You then feel his cockhead press against your shaft as he attempts to enter her pussy.

For a moment it seems that he won't be able to fit, until you feel him press his cock down with his fingers, pushing hard against your own and making enough space to slide in.

He slowly goes deeper and deeper, and you feel his cock slide further and further over yours, until finally you feel a burst of pleasure as his cockhead reaches the base of your own, finally coming to rest slightly deeper than you, your balls pressed together.

You see Lucy's head pointed down at the scene beneath her.

"So much cock...so tight..." she moans, "now fuck me".

You pull back your cocks, and slowly thrust back inside. Dale has his hands around Lucy's hips, and you have yours just above, around her waist. It is difficult to grab hold, and to maintain rhythm with Dale, so after a few times almost popping out, you thrust yourself into Lucy and keep still for a moment, raising your hands to squeeze Lucy's breasts.

Lucy moans, overcome by the intensity of the sensation. You can understand: the pressure of Lucy's pussy and Dale's cock is strong, and you can feel the friction from his shaft all the way along your cock, its hard, textured form giving a much stronger sensation than her bare pussy. With each thrust there is a moment of intense pleasure as the ridges at the base of your heads meet, and then pop over one another as he finally reaches maximum depth, his balls slapping against your own.

You feel a moment of shock: this is the most intense sexual pleasure you've ever had, and it's coming from a cock. You had some doubts about the arrangement with Lucy, but you would never have experienced anything like this otherwise. You don't know what to think, except that Lucy was right, and that at this rate neither of you will last more than a few minutes.

Lucy herself begins to orgasm, screaming in excitement in a way that you haven't heard before. Dale moans with excitement as well: as the one moving, he must be feeling even more stimulation, with the friction not just from your cock, but also from the walls of Lucy's very full pussy.

Note to readers: this chapter has crossed something of a line, in that I am writing about a sex act that I don't have any personal experience with, either giving or receiving. If anyone with actual double vaginal penetration experience, in any role, would be willing to offer any feedback or suggestions to improve my depiction, then I would be greatly appreciative. If so then please either send a message, leave a comment, or post in the feedback thread on the forums.
