Aaralon moaned in ecstasy as the snakeman continued to fuck his ass, "OH GODS, FUCK ME!" screamed Aaralon as the pounding his ass was receiving started to speed up. "AAGH I CAN'T TAKE ANYMORE!" Roared the snakeman as his climax hit him, releasing his semen deep inside the bowels of Aaralon. As the snakeman came, he sank his fangs into Aaralon's neck, injecting him with a small amount of venom.

As the snakeman lay there recovering, Aaralon approached him and asked if he could return the favor. "Why, of coursse you can." replied the snakeman without a moments hesitation. Bending the snakeman over the same rock that he himself had been bent over just moments before, Aaralon carefully started to feed his cock into the ass of the snakeman.

"Ooooh, your good at thissss." moaned the snakeman as Aaralon built up a rhythm, not too fast but not too slow. "There isss one thing that I sshould tell you about a snakemans cum." Yeah, what's that?" "It makes your penis larger, about twice the size it was before, and it is a permanent thing, it cannot be reversed."
