65 to resist cumming
Levi yelped at this, "O~Ow! H-Hey!" as she started getting rougher, which brought more of the strange sensation that was building up within him even as more discomfort followed. Though at least as her cock drooled more and more pre, it made each following plunge easier to take. The smack of her balls against his own however further humiliated him as he tried to ignore the size of them, and also tried to ignore the building sensation rising up from within his backdoor, with tendrils of it spreading to other parts of his body.
C~Can't be... c~can't be what... what I think it is... he thought to himself, even as his toes started to curl here and there and the pain subsided, or was pushed more to the side as that sensation grew. No, he... he wouldn't cum from this. He had to try and hold out! Though a small part of him wasn't sure, as every so often, instead of a cry of resistance or a whimper of shame, a more... pleasured sound would manage to claw its way past his lips.
