Despite her bet, you want to be fair. Eat her out!

"Lie down," you order your girlfriend. "On your back." She complies immediately, and you watch as her tits flatten themselves against her chest. You rub her nipples, and listen to her moans with great satisfaction. "I thought you didn't like my paying attention to your breasts," you tell her.

"It feels really nice," she says. "You can play with them whenever you want..." She squirms a bit as you pinch them lightly, doing your best to avoid causing pain. Soon your hands are full of tit, however, and Jessica's breathing grows heavy. You move down her body and with no teasing cup the mound between her legs. She throws her head back, and you can feel that she is dripping already. You smile at her and lean over to kiss her as two of your fingers work their way inside of your girlfriend. You work her over a bit and she finally begins whimpering. Her body is covered now, a sheen of sweat making her shine.

You work your way down her body and begin planting light kisses on her stomach, then the inside of her thighs, then lightly dance your tongue on her swollen lips. Soon, your tongue replaces your fingers, and you begin thrusting with your tongue into her warm, wet hole. You savor the musty scent and taste as you work your finger up to her swollen clit. Within moments, your girlfriend is shrieking with pleasure, and soon screams with the oncoming orgasm. Your face is drenched in cum, and you smile as you drink as much as you can.

When you pull away, Jess leans down and erotically licks your face clean, tasting her juices from your face. She smiles at you and thanks you with her eyes. You pat her left tit lightly, then roll out of bed.

"Do you like oral sex a little more now?" you ask, taking in the sight of her body as she stretches on the bed.

"Yes," she says slowly. "I think we'll be enjoying that a good deal more."

"Glad you had fun," you tell her. "Now come on: It's time to shower. We've made a mess of each other."
