Start in the car

"Let's start in the car", you say and look around one last time to check if nobody is watching.

"Okay", Joyce says and turns towards you. She reaches over and touches your leg. Slowly her hand moves to your crotch. "How do you want me to start?"

Her hand reaches your bulge and starts to press on your dick, without being rough.

"Maybe slap my balls a bit."

Her first slap was more like a tap and as she could read in your face it didn't hurt she uses more momentum. Her flat hand perfectly lands on your balls, not hard but precise so you have to flinch a bit.

"Yes", she cheers with a grin and slaps again. She continues with several strikes. They are not very hard because your jeans absorb much of the impact and her accuracy decreases but she doesn't stop. Slowly it begins to hurt as she keeps slapping your balls.

"I thought this is kind of a punishment", she stops and grabs your hard dick, "but you really enjoy this, don't you?"

"Of course i do", you say with a smirk as the first pain fades.

Joyce leans forward to you and places her lips next to your ear. She unbuckles your belt: "Maybe i should be a bit stricter and more ruthless?"

"Yes please."

Her hand slides in between your jeans and pants. You can feel the sensation through the fabric and your dick starts to twitch as she runs her hand over it. As she reaches your balls a smile appears on her face.

"No fun anymore", she whispers and starts to squeeze. This time she doesn't hold back and you have to gasp as the pain hits you like a thunderbolt. With her other hand Joyce pulls your head closer to her and starts to nibble your earlobe. The pain keeps getting worse as she adds pressure to her grip.

"I could crush them so easily" she says and her hands keep pressing your balls. She alternately presses your right or left ball and for a short moment you fear she actually might crush them. The pain becomes so intense you have to yell and finally she releases your balls.

"That's more fun then i thought it would be", she tells you laughingly. "You wanna get out of the car so i can kick you?
