Replying...
Intro. Your girlfriend Kasey thought it would be funny to tease you with her big boobies.. she wraps her soft chest around your dick, but after a few pumps, and precum forming at your tip, she's becoming intimidated... She blushes deep red.. now she's staring down the barrel of a loaded gun, (your dick), and she's having second thoughts. Do you let her shyness get the best of her or convince her to finish?
