Susan wins the lapdance contest

After a short hesitation you take your decision.
"Ok, ok. The winner should be Susan."
"Good job Susan!" congratulates Felicia. "Jessica, take off his pants!"

Jessica grabs you, undoes your belt and then your zipper, softly touching your penis through the fabric.
Then Susan approaches you.
"I know I would win. I bet you liked my booty dance John, didn't you?"
You did. You can't imagine how this would feel with your pants down.
"Let me shake that ass for you."
She gets straight to it. Without hesitation she sits on your cock and starts doing her magic.
"I didn't know you are so good at this Susan..." you say.
"You haven't seen anything yet. I bet I can make you cum in your boxers John!"
Girls applaud to that. Some of them stand behind you maybe wanting you learn some of Susan's moves.
That ass feels so good. It wouldn't make a huge difference if she has removed her thongs, they are so small. She flexes her asscheeck muscles - left, right, left, right. Then she starts bouncing her ass on your crotch.

This puts you on the edge now and she isn't slowing down.
