Jeff later on the bed with his ass in the air moaning. It had been a little over an hour since he had started this transformation and already things were becoming a little apperent. He own dick, which had been previously used by Don, had shrunk and his balls had receded into his body. He could feel his connection to Don through the fleshly tube that connected them, even as Don sat in his science class while Jeff was in the dorm. Jeff's skin had started to become a little wrinkly, like a penis, and his ass had totally sealed, save for the fleshly tube coming out of it. Jeff could feel as his insides slowly simplified, his intestines had shrunken and straightened, connected to the fleshly tube now, meaning that Jeff's own penis was all but useless, he knew that when Don had to go, it was coming out of his head, err... Mouth.
At that moment Jeff felt a sudden twinge of pressure building up, a salty taste of semen settling into his stomach, or what was left of it as he got up and went to the dorm door. Jeff left the dorm and started walking, to where he would meet Don as he went to the bathroom, and being his penis would have to be used.
After about ten minutes of walking, which had left the pressure and taste of semen build up in Jeff he had seen Don standing outside the men's bathroom, not even exchanging a glance Don entered the bathroom with Jeff behind him. Walking into the large stall Don dropped his pants and underwear and faced the toilet. Jeff walked over to the toilet and put his face in it, just barely above the water as the pleasure started to flow, Don grunting as semen and urine started to build up in Jeff's mouth, the taste was horrendous, but Jeff loved it, he loved being Don's dick.
Don started pushing and Jeff complied, opening his mouth as a torrent of urine and semen shot out into the toilet bowl. After about a minute of puking up Don's juices Jeff got up as Don sat down to take a shit. Jeff shuddered from the after taste and he loved it, but now he felt the next big change coming along.
