Exhaustion
From Torg Adventure
Despite your Mom's fantastically hot cries of encouragement you began to feel yourself flagging. After all the sex you had already enjoyed this morning, and the small breakfast you only had time to eat half of, your body was almost running on empty. You could still feel a huge load building inside your balls, just waiting to burst, but the energy required to fuck these two insatiable vixens was becoming more than you could muster.
Do you make it?
