What's a woman to get her young, gay bro for his birthday?
Preferably, her husband.
This husband has never had a gay experience, but he loves his wife, and he's curious about the young stallion that is his bro-in-law.
And so is his wife. So, when Vaughn shows up, she leaves her husband with him but watches from the closet as he's jacked and ravished for the first time by a male lover.
