You tease her cruelly

"I don't know," you say. "I'm getting there but I'm happy for the moment playing with your chest."

"Wow man, are you alright?" Yuri says with some surprise.

You improvise. "My doctor told me that I might be able to manage my hormonal imbalance better if I spend longer enjoying the body of whomever I'm with. I'm trying to give it a decent go."

Yuri nods, his eyes wide with respect for your strength and with lust for Lily's exposed tits. "Cool man. I hope it works for you."

Lily is breathing deeply. "You sure, John? I like to give you the first shot." She looks to the tent in your jeans. "I don't want you to feel uncomfortable."

"Maybe in a little bit," you say.

Lily nods, but has stopped paying attention to you. She's now looking to Yuri's jeans, which are similarly bulging. "How about you, Yuri? How'd you like to donate some sperm to Dave's slutty sister? You got to see my nipples, how about you give me some sugar?" She breathes heavily.

"What, here?" Yuri says, shifting uncomfortably.

"Yeah," says Lily.

Yuri looks conflicted. "You mean get my cock out in the mall?"

Lily nods. "Yeah. Come on, I jack guys off in the mall all the time. I'm sure you've seen other girls do it. People understand, no-one minds much if it's to cum for a girl. It's no worse than kissing in public."

Yuri frowns. "I'm not really into public displays of affection," he mutters.

"Fuck," Lily mutters. "It figures that today would be the day John dries up and there's no-one else around but his prude friend."

You has held out just on a white at first, but this situation is actually getting a bit hot. You want to push it further. "I'm just going to put my hand down your jeans, Lily," you tell her. "I want to feel how wet you are."

"Sure," she says, distractedly, as you reach down to unbutton her jeans. You open the flaps to reveal a thin landing strip of pubic hair instead of panties. Yuri's eyes go wide. Lily looks at him with a gaze of lust. "Take a good look Yuri," she says. "I don't mind you looking if it makes you hard enough to give me your cum."

You put your hand down her jeans, and feel her lips open easily to your touch. Lily gasps as your fingers slide up and down her vulva. "That feels really good, John, but it's not the same as you coming all over my face. Are you going to get your rocks off with me or what?"
