The barista leans back into the wall behind him as his whole body starts to change. Basking in his mind blowing, otherworldly pleasure as his pecs jut forward a little bit more each second, pressing his hypersensitive nipples against his shirt, and his pants feel tighter and tighter against his legs as his dick is pressed against his jeans. He opens his eyes in bliss, as each pulse of his nipples make him feel bigger and heavier, and is greeted by the weird man staring intently at him, fondling at his own pecs.
"What... hgnn... are you... ugh... doing... to me?" He asks between moans and whimpers.
Colin is taken aback by the question. It wasn't often people managed to maintain enough cognition to form a full coherent question while his magic was at work. He surely did not expect a tavern keeper to. Maybe it wasn't prudent to just start transforming the worker at a magic 'bar' without properly accessing the situation, maybe the guy was a wizard himself!
"Who... are you?" The man managed to ask.
"I am Colin the Shifter! And right now I just need to do a little experiment" He said, as he again expanded his spell on the now muscular 'barista'.
He suddenly felt the clothes he was clinging to in his desperate attempts at squeezing his nipples suddenly come undone, he looked down just as the threads of his shirt fell from his enlarging torso, fully disappearing before hitting the ground. He felt the wind on his growing chest, it felt amazing. His cock slapped his lower belly, and for a moment he remembered it, forgotten for better feeling stimuli.
Just as he was about to try asking another question, though, he was again reminded that his cock existed. The throbbing that pulsed all through his body began pulsing upwards from his member's base, into his balls, all the way to his 10 cm cock's head.
Immediately he reached for it with one hand, as the other was firmly kept clamped to his nipple, as the pleasure started to become too much. He felt his orgasm coming as his growing hands pumped at his slowly growing cock. His moans had started to become louder and his breathing more erratic.
Colin caught on to this, and a quick shift of focus later and he started revising his spellcraft so far. 'Right, so: libido and nipples are done, and now I have muscle growth, penis growth and orgasm denial all at the same time' He listed in his head as the growing barman's moans started becoming increasingly frustrated. Colin looked at him while pleasuring his left nipple. He was huge, big juicy nipples on a strongman's frame glistening with sweat feverishly stroking a decently sized dick. 'Maybe next I could...'
The barman felt his spine shift slightly, and a pleasurable chill run from his skull down both his legs, as his world started to become slightly smaller and then all sensations in his body ceased suddenly, and he came. He had never come so hard his entire life, he moaned and moaned as his cock spurted wad after wad of cum all over the counter's inner side and the floor.
Colin stared in a mix of confusion and frustration. A small drop of cum landed on his cheek, as he calculated how much magic was being channeled at the time the spells failed.
The barman slumped back into the floor, exhausted. His descent cushioned by his now enlarged butt. He snapped his eyes open, as he had almost forgotten. He looked down at his pro bodybuilder-like proportions in awe, he tentatively touched one of his large nipples, and was rewarded with a sharp jolt of pleasure through his body, they were red, puffy and extremely sensitive. Lastly he took account of his dick. He had to say, it wasn't as big as it had felt when he came, it was not bigger than 16 cm now, still, it was a lot bigger than it had been.
"What the FUCK did you do to me?"
He said, as he got up
