You slam it in

You figure this might be your last shot and practically throw yourself onto her pussy. Your dick thrusts deep into her moist sex, meeting little resistance a jolt of pain shoots from your nuts as they slam against her ass in your over eagerness. You hear her giggle as you gasp in pain saying “careful boy, don’t go hurting yourself before I get a chance to”. You begin thrusting rhythmically against her, but it dawns on you that with the little friction you’re feeling, it’s unlike you’re stimulating her in any meaningful way.

Your suspicions are confirmed when you look up to her face, a bemused expression plastered across it as she looks down at your pitiful attempt to get her off. “Going to have to try a lot harder than that boy, it feels more like a tickling than a fucking, can that thing seriously get girls off?” Staring down at you over her breasts you take this as a sign to pound her harder, gritting your teeth as your testicles slam against her ass, you fuck her with everything you’ve got, the sound of slapping growing louder from between you.

After nearly ten minutes your balls are throbbing a bright shade of red from the repeated impacts against her toned ass, you try to gauge her expression for how well you’re doing, but she barely seems to be paying attention, only giving a the occasional grin whenever you grunt in pain. Were it not for the pain in your nuts and the thought they might soon be separated from you, you might have already blown your load, but you dig deep and try everything you can to get her off In one final push.

Not long after you feel her pussy clench slightly and become more wet, giving you hope she might be getting near, then you feel a firm grip on your sack and a snigger as you hear the chilling words “times up”. It crosses your mind that you simply weren’t big enough to please her, and that the excitement you felt from her at the end was at the anticipation of destroying your now doomed balls.

She tugs hard on your testicles pulling your erection free from her, she then grinds them roughly within her hand, watching them slide and slip past one another amusingly. “Well that sure was disappointing, I could have helped you out, but you really didn’t sell me on trying to get me off, felt more just like you were using me like a toy to get off your final load, and you didn’t even manage that!” She says, laughing at you squirming beneath her grip.

“Well tell you what, don’t say I’m without mercy, I’ll give you one more shot fucking me, but this time we do it my way, there’s something I think your tool set is the perfect size for” she grins wickedly as you make up your mind.
