Nod your head

You don't know what to say but it doesn't matter anyway since you are in a state in wchich you will submit to everything they ask you. You just nod your head.

"I knew he would like it!" Patricia is proud of her idea.
'We don't have much time so let's establish the rules. Three girls per discipline. Then John will decide who did the best."
You have no idea what they have in mind yet. You just agree on everything to spend some time with your unclothed friends.

"Let's choose our first discipline. How about the contestants dancing on John's lap?" suggests Felicia.
"You mean a lapdance?" Eva corrects her friend.
"Yes, exactly. One minute per girl, then John announces the winner."
You are stunned and unable to tell if what you just heard wasn't just in your head. Your erection is getting fuller.
"He seems to like that idea Felicia." Jennifer notices looking at your crotch. You blush but then relax. This is going to be good.
"Ok, so the contestants are... Susan, Patricia and Linda. The rest of them step aside to make some room for the competition.

"I go first!" Patricia heads towards you. She is wearing sporty lingerie: a perfectly sized bra and tight, high-cut briefs. When she turns around you admire her asscheeks, sticking out at the bottom. Her skin is very smooth and she smells of very fruity perfumes.
"Hi John. Shall we start?"
You nod again. Then your heartbeat rises as she turns around and sits her firm butt on your laps. It feels great and your cock is as hard as it can be now. She moves her hips around higher and higher. She is very gentle. Her ass starts touching your cock very slightly. You wish your jeans were out of the way to feel it a little better.

"Switch!" shouts Felicia. Already? She was barely even touching you.

But this doesn't matter. You have another girl, Linda, already pointing her ass at you. She stands very close and puts her butt on your chest. You didn't get to have a look at her boobs but feel tempted to undo her bra right now. She is wearing a black lacy bra and matching pair of thongs so at least you can see her ass in full glory.

Your take a deep breath as she lowers her butt and touches your dick with it. Her ass is soft but firm at the same time. She feels your cock thoroughly and opens her mouth like she is positively surprised.
"You know what John? This makes me really horny. Your dick is so..."

"Switch!"

Linda blinks at you with the look saying "we can finish it later". You ready yourself up for Susan. She leans over and whispers to your ear.
"I saw how you looked at Linda. I'm going to win this though."
She seems determined. As she bends over you try to spot her pussy lips through the tiny thongs she's wearing. No luck. She comes closer and starts booty dancing right before your eyes. You watch her asschecks bouncing and imagine how it would feel like on your cock.

You don't have to wait long to find out. Susan bends her knees and puts her ass right at your erect penis. She smiles. Then she starts twerking on yor cock vigorously. Her breathing is noticeably faster now and you can hear giggling somewhere inside the locker room.

"Switch!" your hear Felicia again. "Ok John, that were all of the contestants. Now you should decide who should win."
You don't know which one to choose.
"Let's make it a tie girls" you try to not antagonize any of them.
"John, you have to choose the winner... I know, let's make a new rule. You get two more minutes of lapdance from the winner, how about that? Let's get rid of your jeans too."
