Give her a snack.

Jess's hands begin massaging your balls as her moans become impatient whimpers. She pulls off of you and looks up into your eyes. "Are you going to cum soon, or what?" she asks. You look down, breathing heavily. You **** her head back down on your dick to her surprise and hear her gasp as her mouth is filled with your dick.

"I won the bet. Keep sucking, and you'll get your treat." You try to do your best angry voice, but her skill is keeping you from any convincing acting. Jess's head begins moving faster and faster as she tries to draw the cum out of your cock like a milkshake through the straw.

Despite the bet, you love your girlfriend and you begin moaning as you warn her about your upcoming load. "I'm gonna shoot," you breathe.

"Good. Let it go, big boy!" your dick pulses and throbs as you shoot a large glob of cum into your girlfriend's mouth. It's followed by several others, and you sigh as you grab your girlfriend's head and slowly pull her deeper onto your dick. You feel Jess's throat move as she swallows your load and you let her head go to grope her tits. Jess slowly pulls back, cleaning your cock as she goes.

"Feel better?" she asks. You nod, petting your girlfriend's breasts lightly. She smiles as she watches you slide down on the bed. "What do you want now, baby? You've got me for the rest of the day."
