With the little accident that just happened, the sexy mood was already dead, you decided. Grabbing the flashlight, you were about to set it up to full pink to fix Melissa, maybe salvage the situation, but then you decide you're not in the mood for sex at all anymore. "Melvin, eh?" you think about the absurdity of the change, even affecting her name... "So she's practically a guy now, huh" feeling a sudden sort of curiosity, you decide to have a bit of weird fun with Melissa. "Well then, let's give 'Melvin' a fair shot for the evening, shall we?" You chuckle as you set the light to a lower intensity of blue and shine it profusely over Melissa's entire body. The result was rather interesting you think, as you watch her uniformly morph into a nerdy looking young man. The newly minted person remained the same size and height as Melissa, though being a male now, that was a rather puny stature. The shoulders were a bit broader, sure, but Melissa's slim physique was replaced by a slightly pudgy, slightly hairy male body. The new penis was average in size and the face resembled your girlfriend's only in a passing manner. Her once long platinum blonde, straight hair replaced by a closely cropped, curly brown haircut. The clothes Melissa was wearing when she came over also changed as they flew back onto the transformed person's body, dressing her... or rather him up in a fittingly nerdy outfit. A pair of checkered slacks, a tidy white shirt and brown loafers. A pair of thick glasses and a slightly crooked bow tie completed the outfit.
You sit up from the bed and walk to the person who used to be Melissa. "Uh, Melissa? How do you feel?" You tentatively ask her/him and as you gingerly straighten out her/his bow tie, she/he looks at you, eyes looking a bit blurry behind the thick glasses.
