Jeff attempted to release the pressure in his bladder as he normally would, with his regular anatomy.
An incredibly weak trickle of urine began to dribble from the nipple at the end of his crotch-breast, dripping pathetically into the toilet bowl.
The sensation was unpleasant, like being constipated but for number 1 rather than number 2. He still felt the pressure on his bladder and it just wasn't getting released fast enough.
He decided to try to help it along, gripping the breast with both of his hands and sliding them down its length. This had immediate results, increasing the flow dramatically for just a second and bringing a sudden sensation of relief.
He realized that he would have to keep going. Bringing his hands back up to the base of the breast, he repeated the motion again and again, effectively milking himself. Now the pee was flowing at an acceptable rate, sending shock-waves of satisfaction throughout his body. There was something inherently satisfying about squeezing and stroking the breast between his legs too.
He found himself continuing to "milk" his crotch-breast long after the urine had stopped flowing.
After drying off the nipple with a bit of toilet paper, Jeff sat down on the toilet and continued playing with his jiggly new acquisition. He cupped and stroked it with one hand, then licked index and middle fingers of his other hand and began to furiously rub the nipple and areola with his moistened digits.
He closed his eyes and tilted his head back, breathing heavily from the pleasurable sensations, but it wasn't quite like jacking off, and with his new anatomy it seemed like he might not even be able to cum.
Eventually he gave up and stopped to catch his breath.
As he struggled to squeeze himself back into his pants, he at least felt a bit better knowing that he could still perform basic bodily functions.
