Threesome with another girl

"Well, since you're bisexual, it could be fun if we invited another girl to join us. That way, both of us get to experience something new," you begin. "And if we were to sleep with another girl, I'd want one who was different than you. Not better, just different. Maybe even your polar opposite," you add tentatively, looking up at Lily to see if you're making her uncomfortable. If you are, she gives no sign of it, so you go on, trying to envision this not-Lily you're constructing in your head.

"She'd be taller, with richly-colored skin. Maybe lean with a runner's physique, or maybe really curvy and thicc," you muse, trying to get your silly pronunciation across. That earns a chuckle from Lily. "She'd be flexible, able to put her legs over her head or do a split on my cock," you add.

"And she could take you all the way inside her," Lily continues for you, much to your surprise. You nod in agreement, and she goes on.

"You could fuck her hard, with nice deep strokes, until your balls slap against her, while I sit on her face," she intones, her eyes distant and full of excitement. "And after you cum inside her, I'd slurp it all out and lick you clean, because while her pussy might be better than mine, your cum and your cock will always belong to me," she finishes, her eyes flashing as she looks at you.

"Yeah, something like that," you say breathlessly. There's a long pause.

"Well, if you ever want something like that, just ask first, okay?" she says with a playful wink.
