Finish your end of the deal, then get more head.

“Tell you what. I'll finish you off if you promise me another blowjob. I won't collect first; that's just mean. But all I can think of right now is that amazing mouth sliding up and down my cock.”

“Fuck yes. You know I'll blow you. I'll suck you until you can't breathe. Please John. Eat my pussy.” You grin and lightly pat Jess's thigh. She immediately lifts it and you decide not to waste any time. You lightly tongue her clit at first, and the release from Jessica, simply feeling it is amazing. Her leg falls on your shoulder, trapping you. Your tongue continues to flick her clit very gently and you steal looks up to your slender girlfriend. Her eyes remain closed, and her hands gently cup her breasts shaking them as she trembles from your ministrations. You finally allow your tongue to enter her pussy, brushing her clit with your nose as you lightly lap inside of her.

“Yesss.” Jessica's pleas become a hiss as you work your girlfriend over. While you know Jess doesn't like giving head (or didn't seem to before today), you've always enjoyed it, and you've paid special attention as your girlfriend twitched and moaned throughout your relationship. She once confided to a mutual friend that you could get her off faster than anyone she'd ever known.

Your ego swells at that memory, and you do your best to finish Jess off. She's very wet and you slide two fingers in. Jess gasps and begins bucking against your hand. Your tongue moves to her clit, vigorously attacking it and soon Jess trembles and shakes. You feel her leg slide off of you, and she stiffens, gasping and shrieking as she comes over your finger. You leave your hand at her crotch as she gasps, trying to draw breath. You casually grope her breast.

“Thank you,” Jess murmurs, still recovering. “That was fucking insane.” You smile and unzip your pants, sliding out of them. Your cock has grown again; it's already rock hard.

“I'm glad you enjoyed it. Now for your end of the deal.” Jess smiles.

“One blowjob coming up,” she giggles. You smirk at the pun. “This is by far the most dick I've sucked in a day,” she says. She immediately grips your cock and begins stroking it. “You like getting head, John?”

You grin at her. “You do have a way of making it heavenly,” you say. Jess smiles, taking the compliment in stride.

“Despite my innocence and inexperience?” she says, flitting her eyelashes at you. “I mean, before today, I thought blowjobs were just for whores,” her mouth sucks in the head of your dick. “But I'm not a whore, am I, sir?” She's put on her sweet, innocent schoolgirl voice. Her mouth slides back over your dick. “Well, am I. Am I a whore? If I'm a whore, then I need to know.” She cups her tit lightly.
