Have her masturbate in front of you

With a certain amount of satisfaction you see your goo drop down her face onto her tits. You can see her pussy all wet and her nipples errect.

"You liked it, huh, bitch?"

She nods and blushes.

"Fuck yourself!"

She looks at you disturbed.

"I mean it by the word: fuck yourself!"

She blushes even more and starts to massage her tits. Then one hand drops between her legs and she starts to rub her clit. She starts to moan, her eyes closed. Her body starts to move and she enters a finger into her cunt.

"More fingers. At least 4!"

Obediently she shoves 4 fingers into her cunt and starts to fingerfuck herself. She does so slowly at first but with time her fucking and breathing become faster. Your goos slides down her fine, muscular body and your limp dick starts to fill with life and blood again. Her moaning becomes louder and she throws her head from on side to the other.

Then she stops for a moment, her eyes and mouth wide open. Then she almost screams and cums, her pussy spraying her hot juice all over the carpet.

You have already started to pump your dick again and you could just continue fucking her.
