Woke up in a strange bed! What now?

Wow, what a number that was! I wake up in the morning and don't even know where I am. I turn around and there's a naked man lying next to me ... So far so good. Only he's naked and already wanking his stiff cock. I'm totally perplexed but the sight excites me because I can see a fat, stiff cock. He's not exactly reserved either and tells me not to be so coy. Well, I definitely feel like it, but how should it end? What do you think, should I dare?
