5 minutes? Whats the point.. sure i'll blow a load but what about her. I guess I would spend those minutes working to get more minutes.... I hear my tounge and lips can be persuasive.
If I were lucky enough to have 5 minutes with my favorite porn star, I would choose oral. The only thing is, I'd rather give than receive. I'd go down on her and hope that after only 5 minutes, she would be turned on enough to ask for more time.
