What a surprise with my neighbor lying on his bed with a stiff cock.

I go out to the terrace to get some air and i look like a statue when i see my neighbor completely naked in his bed and jerking off. my girlfriend is about to get home but like a curious and playful kitten i cannot resist seeing him close even for a moment and when i want to realize it i am at the door of her house with my cock in my hand. a couple of moans escape me and my neighbor realizes that i am there. with a smile on his mouth he invites me to come in and enjoys moving his cock inside my mouth.
