Train her endurance...

You don't get much of an opportunity to fool around with your plaything for the next few days. Work is busy, and as usual, you're not getting much in the way of action from your wife. By the time you organize to meet with Gemma that weekend, you are horny as hell and ready to explode. She arrives at the motel, strips naked, and immediately gets to work servicing your cock with her mouth. As you stand there enjoying the blowjob, you're reminded of the very first time she jumped you in your car, causing you to blackout from her vigorous throating. You wonder now whether she can stand a taste of her own medicine. You throw her onto the bed and straddle her chest, slapping her cheeks a few times with your hard dick.

You mount Gemma's face and shove your entire cock down her throat. You face-fuck her violently, smashing spit and mucus all over the place as your slam your shaft in and out of her mouth with piston-like speed. You’re driven by pent-up frustration, and imagine her mouth is your wife’s pussy as you angrily fuck the shit out of it. She struggles under the weight of you, tears streaming down her face, snot spurting out of her nose, and her cheeks turning bright red as she struggles to breathe. Wildly, her head bounces up and down off the mattress as your slam your crotch into her face with as much **** as possible. It takes you only a minute before cum starts blasting out of your cock, and you lean down with your full weight and **** your entire length as far down her throat as it can go. You pinch her nostrils shut as the cum runs down her throat until she goes blue in the face and almost passes out.

You repeat the process for the next few hours. She strains, pinned down against the weight of you on top of her, as you absolutely brutalize her throat, bringing her to the edge of unconsciousness with every serving of cum you dish up into her gullet. By the time you've run dry, your entire body is covered in a sheen of sweat. As you slide your cock out of her mouth, she belches loudly, burping up a torrent of cum that runs down the sides of her face. You note with approval that her cunt seems to be slick with arousal, despite the pummeling you just gave her.
