The cliche actual sex scene

Karyn laughs again, loud this time.
"Holy shit Jon, that was amazing." She says.
"Yeah. Maybe we could stand to do that again sometime? Maybe somewhere a little more public?"
"Mr. Jon." Karyn says, in a mocking tone. "If I knew you had this side to you, I would have jumped you a long time ago."
"I wish" you say. Then quickly let go of the stone. "Fuck, that was close."
You see the rock float above the bed, as if by magic. Seems like 'dropping it as fast as possible' counts as willingly giving it up.
"I wish we had some music" Karyn says. Her sound system comes to life.
"And I wish I couldn't get pregnant for a month."
"Only a month?"
"Just to be safe" she answers. The two of you are still invisible, so it's Karyn who reaches down to line you up. Your tip is pressig softly into her.
"Ready?" she asks.
You answer by pushing into her. You both moan at the same time, the full force of years of pent up feelings coming forward.
Karyn hugs you tight, kissing you as you work out a rhythm together. Her brests push against you, and you can feel the coldness of the rock against your back. She's so warm, it feels like you were meant to be like this.
But things don't stay slow for long. Within minutes you're slapping against her, each thrust earning you a little moan. She's pulling you tight against her with her legs.
You aren't going to last much longer. You try to desperately hold on for a few more seconds.
"Karyn, I'm.. "
But you can't finish the sentence, gasping loudly as you throb into her, feeling additional warmth and wetness paint her insides.
"Jon, that's, that's, ah!"
The feeling is enough to do it for her, and your increasingly sensitive dick is pressed down on by Karyn's contracting pussy.
You fall on top of her, huggung tightly, and stay that way for a minute. Just breathing together.
Eventually though, Karyn moves to sit up, and you go with her. Your dick falls out of her with a wet plopping noise. A lamp flicks on, and you look down to see two strange white shapes floating above the sheets.
Looks like your cum didn't stay invisible.
"Oh, weird." Karyn says, evidently looking at the strange moulds of her insides, and your penis. "That's kinda cool."
"We're going to have to wish that away when we're fucking invisibly in public" you say. "In the Louvre, the Oval Office, the Bellagio..."
Karyn hugs you, her face pressed into your shoulder.
"I love you Jon."
"I love you too."
Suddenly, you both pop back into the world of the visible.
