He was getting into a good rhythm before everything goes horribly wrong to quickly for Jason to process. Suddenly pleasure turns into horrible gut-wrenching pain. The smell hits his nose and the desire to vomit is right there.

Everything felt slow as he panics grabbing Dodger's burning hand.

"S-Stop!"

His voice in his ears sounds a lot quieter, but in reality, it was a guttural begging screech.

He's never felt this much pain and his entire being is trying to process it, he felt paralyzed before he starts to struggle, causing himself more pain.
