Jeff was getting turned on by the exploration of his new body. The only problem was his lack of arms, every movement was mainly a tease, with no ability to push himself over the edge. Soon he found himself writhing around on the bed, using the momentum of an inchworm to slide himself across the soft cotton fabric of the sheets. However, the harder he got, the more difficult this type of movement became. As much as he wanted to, the average sized disembodied cock just didn't have the tools necessary to get himself off. Although, by now he was leaking quite a bit. Eventually he huffed and gave up, letting himself shrink until he was completely flaccid. Once soft, he found it much easier to move himself around again.
As he was exploring the changes and just starting to get the hang of walking around using his balls as legs, he heard the door to his room open.
Shit!
He dove under the blanket as fast as he could and peeked out to see who had arrived, hoping they hadn't seen him before he could hide.
