"Your ass"

Olivia smiles. "Of course you do." She turns around, giving you an amazing view of her plump ass and shakes it. "Why do men love to go for the ass so much?"

You're not sure what the answer to her question is, and you don't have much time to think about it, because suddenly she steps up to you as close as possible and places a hand on your hard crotch.

"I'm just kidding." She says. "I know why. It's because it let's them show who's boss."

You don't think your cock can get any harder, but now under Olivia's hand, accompanied by her dirty talking, it gets harder than maybe it's ever been.

"It's time for me to see it." She says. Of course she's right.

So you slowly unzip yourself, unbutton yourself, slide your pants down. You don't want to tear them off like an eager doofus. She stares down at your bulge and smiles wide. You pull your boxers down, exposing yourself, right there in the middle of the store, to Olivia.

She bites her lip, then licks it. "Very nice. It's quite nice." She wraps her hand around it and gives it a couple tugs. "I think I'm going to enjoy having it buried in my ass."

You're going to enjoy it too. You've stopped caring that this is happening in the middle of the store. You just need it to happen.

"Now pick the dildo you want to share my ass with." Olivia says, somewhat taking you a back.

You're not even sure what she means exactly. "Wait... what?" You hear yourself ask clumsily.

"Eight cocks. I can do math. That means some of them are going to have to double up right? So you're going to have to train me how to take two in my ass. So you'd better shove one in and join it. Unless you have a better idea."

You glance at the dildos. They're all so damn huge. You had no idea this would be the case when picking them out. Not that Olivia's dirty mind and dirty desires don't turn you on. But suddenly you find yourself in an uncertain position. She's depending on you to make this work. And you've never come close to doing anything quite like that before.
