More foreplay...

"Mmmm, I admire a little self-control." She continues softly stroking your dick and pulls you closer, leaning closer, and closer...

Suddenly you're turned to face her and she's kissing you full on the lips with a fever, as both of you start playing with each other's hair. Your cocks are doing the stroking themselves now, as she's practically sitting on yours (but not quite). Your lips, meanwhile, are almost glued to each other, and you barely have time to breathe with all the tongue work.

She slowly works her hands down your back, eventually starting to grope your ass softly. After a few moments, she breaks off the kiss and breathes into your ear, "Oh my God, I'm so fucking horny, I can't take this anymore. I want you and I want you now, little bro."
