There were no words to describe the feeling on your cock while you fucked Jessie. Saying you were on the edge didn't even begin to describe it. Your cock felt like it was twice its normal size, and every ounce of it was tensed, straining to force out the largest orgasm you could imagine.
With one thrust into her pussy, your whole body was tensed, your mind was wild, you were on the verge of crying, your cock swelled, your balls tightened, and your body pushed.
And the next thrust was even more intense.
And the next more intense than that. And the cycle continued. You never got the relief of cumming, and you never got the relaxation of the sensations staying the same. It was constantly mounting, driving, pushing toward the unachievable goal.
