He doesn't get to

It was barely five minutes later that Kiba felt himself about to reaching his peak and felt it was best to warn his mother. “Mom, I’m about to cum!” He shouted with his tone filled with nothing but pleasure.

Tsume seemed to not hear Kiba as she didn’t give any indication that she heard anything. Instead she just kept riding Kiba bringing him closer and closer to his limit.

After another few moments Kiba reached his peak and shouted,” I’m cumming!” Kiba closed his eyes and threw his head back to enjoy the feel of his release. However, just as his first shot of cum was about to be unleashed he felt a tight grip on his balls stopping him from cumming.

“Not yet boy! I’m not finished with you yet!” Tsume growled out with his balls grasped tightly in her hand. Being so close to relief and being denied was maddening to Kiba. He wasn’t sure what he was going to do but he needed to think of something fast.
