Whether it happened by accident or not, Bill wasn't sure, but as he tongued the mating genitals in his face, Jeff's c**k slipped all the way out of Crystal's cunt on the backstroke, and as he pushed forward again, it missed its previous mark, and went right into Bill's mouth.
Although it surprised him just a bit, it didn't stop him from opening his mouth, and letting the hard member enter, and he swirled his tongue around it.
In just that single, few-second introduction to c**k, Bill began to get why Crystal liked it so much. The skin was smooth and warm, and rippled by his veins; the head was spongy; and the taste of Crystal's p***y juice mixed with Jeff's "musk" or whatever it was, was something completely new, and somehow, very arousing.
Jeff f****d his d**k in and out of Bill's mout
