Let her go

With that much enthusiasm, you don't think you need to hold her any more. You let go of her restrained arm and flick the gag out of her mouth. You pull out of her pussy and she whimpers when your cock leaves her slit. She looks up at you over her shoulder with her mouth open, panting. She rolls on her back. Her hands stroke up her body and grab her breasts, squeezing them while she moans. Then she gets a gritty look in her eyes and whispers, "Do that some more, or I'll scream for my daddy."

You grin at her, saying "Okay." Then you plunge back inside her slippery pussy and kiss her hard, slipping her tongue. You grab her tits firmly and pinch her nipples. She cries out into your mouth, which muffles it from her daddy's ears.

In just a few fast, hard strokes, the blond farm girl is coming all over your cock. You keep pounding her into the mattress for five more minutes as she continues to have several orgasms back to back. Finally, you can't hold on any more, and you explode inside her, filling her womb with your spunk. It's your turn to shout into her mouth. When she feels the hot splash of his cum, her orgasm redoubles in intensity, making her eyes roll back as she loses herself in the forbidden pleasure and danger of taking a stranger's molten cum, knowing how fertile she is. After half a minute of thrusting and spurting, you collapse on the farm girl.

She holds you and occasionally has an aftershock that causes her pussy to squeeze you. You remain solid in her cunt.
