Small insight into the reaction of aggressive handling.(Handjob Edging)

Andrew's breath quickens, it's one thing to masturbate normally but seeing his own cock twitching so close to his face. How every slight touch of his palm and fingers sends a visible jolt through his cock. His once slow pace has gradually become more frantic as he lost himself in studying his own penises reaction. The once dry friction has has become slightly slick as his arousal increased and precum started oozing from the tip.

Feeling the strong desire to ejaculate breaks Andrew from his trance like state, taking a deep breath and letting his grip slip from his erect cock. Andrew leans back into his chair staring at his engorged twitching cock. So close it got to releasing the tension consuming it, mere seconds from cumming, how easy it would be to quickly end its pain and grant it the bliss it so yearns for.

Instead Andrew remembers his intention when he first got back to his dorm room, how he wanted to understand his condition, as the more he knows about it the higher chance he could figure out how to reverse it. He got lost to easily in masturbating and forgot that this change to him needed to be studied. Feeling his need to ejaculate die down Andrew leans forward again to resume his experiment into his condition.

"Oh" Andrew unintentionally mutters as he feels a blush spread across his face, he remembers Katies words about how 'experimenting is good' He won't deny that some part of him started this with curiosity, however he convinces himself that these changes to his body may in-fact be permanent and the deeper he understood his situation the easier his life would be in the future.

Preparing himself to continue his study, Andrew takes a brief glance at the clock in his room and makes a mental note that he probably only has time for one experiment before dinner after cutting his Alchemical Reagents class short and having the embarrassing interaction with Katie there isn't much time left.
