Not too eventful. However...

The entire drive to "your" boyfriend's house you couldn't shake the desire to send a slutty picture of Michelle to the gym teacher. The thought was invigorating and you can already feel some moisture pooling between your groin.

You arrive at Mark's place and are immediately greeted by a palatial suburb house. No wonder she dates this guy, you think. Mark runs up the porch stairs and call out to you.

"Michelle! You didn't bring a bathing suit, did you?"

No, you didn't.

"Fucking classic." Mark replied blithely. "Just wear the one you left last week, I guess."

Mark disappears for a moment and returns with a skimpy white two-piece.

"Here ya go babe" He kisses you the cheek.

"Thanks!" You say with feigned cheerfulness.

You'd like to enjoy the pool but the fact that everyone here is a stranger to the real you is a bit off putting. Your disquiet is also compounded by a powerful urge to send the gym teacher nudes.

Confused by the geography of the house, you wander into one of the main floor rooms to change into your bikini. This is also the ideal time for a strip-tease, you realize. Rummaging through your bag, you find the gym teachers phone number.

503-567-2349 David

You add the number of into your phone and take a few demo photos: one with your hand on your breast, fully clothed; one with your hand slowly pulling down the straps of your dress to reveal a lone nipple; another completely naked your hand hovering over your pussy. Finally, you also take a short video of you rubbing your wet hole, all the while whispering 'I wish this was your thick, fat cock inside of me David.'

Impressed with your set of nudes, you send them off one by one and close the correspondence with a brief 'Imagining what you'd do to me...'

In the distance you hear the faint _ding, ding, ding, ding _of somebody receiving text messages but you don't think much of it. You slide into your bathing suit and enter the hall. The door across the hall opens and you're greeted by a familiar face. It's the gym teacher.

"Dad?" Mark calls from the downstairs. "When are you and mom leaving for your trip?"

The gym teacher replies, "In a couple of hours! Sorry son, your mom and are a bit delayed!"

His eyes meet your and he forces you back into the guest room.

"I should've known you'd be here." He says, stroking your shoulder.

The shock silences you. He unzips his pants and presents his large cock.

You slowly grip his member and begin to stroke it.

"You said you wanted this inside of you."

You don't hesitate. "Oh, I do."

He takes of your bikini top and caresses your tits.

"Then ask for it." He whispers.

"Fuck me." You reply, quietly.

He strips your bikini bottoms and cups your sopping wet pussy in his hands.

"How badly do you want it?"

"I want you inside me so so badly." You reply, too horny for words.

"Show me." He pushes your head down towards his cock.

You wrap your lips tentatively around the tip before diving head-first into the experience. You slurp loudly along the length of his rod before allowing it to slip deep into your throat. He thrusts his hips and you try your best to maintain your composure for him.

He pulls out.

"Oh, did you mean your pussy?" He asks quietly.

"Yes. Please. Please just... fuck me." You stand up and lean against the window, presenting your soaked pussy lips.

He approaches your from behind and lightly teases the lips of your pussy with his cock.

"Fucking put it in. Please. I need your cock inside of me. Please, I'll be your little cum-slut. I'll let you fuck me whenever you need it. Just fill me up. I want your cum. I want -" You're unable to finish your mindless begging before his plunges his cock into you.

His size forces an involuntary squeal, loud enough to betray your infidelity. He places his hand in your mouth to shut you up. Sucking on his fingers certainly helps quiet your moans but they're very much present.

He thrust his cock as deep as possible and lingers for a moment. You feel an uncontrollable pressure build between your legs.

Suddenly, you hear a knock at the door.

"Dad, you in there?" Mark calls from the other side of the door. "Mom's looking for you. She wants you to get going."

You try to keep silent with your boyfriend's dads cock stretching the limits of your vagina.

"Sorry son, I'm still trying to change. I'll be right there." David says.

He thrusts one last time, his cock erupting into a river of ejaculate. You stand there numb with pleasure as he fills you up. In the afterglow you notice you can see Michelle's friend suspending her legs in the pool from the window. In fact, you just got fucked in full view of the pool. You're not sure if they could see the inside of the house, but the thrill of exhibitionism adds to your orgasm.

David throws you a towel and your bikini then guides you to the closet.

"Get changed in here. Wait a few minutes before leaving. If anyone asks you were in washroom."

You enter the closet.
