Why not

"Sure." Chris says.
"Cool. My name is Dwayne. Yours?" Dwayne asks.
"Chris. Nice to meet you." Chris says while putting out a hand.
"Nice to meet you too Chris." Dwayne puts out a hand and passes Chris's hand and head straight for Chris's ass. He starts to rub it and says, "Nice ass. Want to go out later?"

Chris gets shocked for a bit by the hand rubbing up and down his ass, the bluntness of Dwayne, and the fact that no one is conveniently around to see any of this.

"Sure we can." Chris says while removing Dwayne's hand from his ass. "We should out go to a food joint to get to know each other."
"O yea. Got to wine and dine you before putting you to bed." Dwayne says as he pulls out his cell. "What's you're number we can meet up in a couple of hours. I got some things to take care of."
"Ok." Says Chris as they exchange numbers.
"Lets meet up at the taco place right across from here in 2 hours. I'll be there first to get our table ready for us. Call when you get there, and don't keep me waiting." Dwayne says as he puts away his phone. "See ya later Chris." He says as he slaps Chris on the ass and walks off.

Chris gets a little flustered about Dwayne touching his ass and shoves it away as he gets both pizzas he wanted and some snacks and head home.
