Personally, I have two:
1. He relaxes on his couch and watches his favorite porn. I get on my knees and service him long, hard and s-l-o-w to the ultimate climax. I did that once on a guy for over an hour!
2. We meet at a sex club - something like Slammers in L.A. or Blow Buddies in SF. He goes in first, checks in, takes off his shirt and begins walking around the club. Maybe 10 minutes later I enter, check in and begin roaming the place until I find him. We go in a glory hole booth and I worship his body and suck him dry. If we are playful, perhaps he goes into a neighboring booth and I suck him through the hole. He can have anyone join he wants, he can even tell them about our relationship, but only I get his cock! (I did that once at Blow Buddies with a muscled escort who then had another muscled escort and I had two for the price of one - so to speak.)
