Step up behind her
From Create Your Own Story
You casually walk around behind the young lady with her hand down her pants and step in close. Your shorts are still on the ground by your SUV, where Janice is still getting pounded, and your cock is rock hard in your hand. Not one to be shy, you lean forward against the young woman and press your meat against her.
"I wondered when it was going to be our turn," she says. "My name is Kim. Will you fuck me now?"
"Gladly," you say, as you pull her shorts and panties off.
Kim leans forward, putting one hand on her knee while the other continues to rub her clit. You press the head of your cock against her wet pussy and it slips right in.
"Fuck me as hard as my boyfriend is fucking your wife," she says. "I like it rough."
You gladly oblige and start slamming her pussy hard from behind. It's been a long time since you had another pussy around your cock, and it feels good. You slam into her harder and harder.
"Rougher," she says. "I like it hard!"
You grab Kim's hair and give it a rough tug, pulling her head up.
"That's it. Show me who's boss."
