Lucy was sat in a cubicle of the same bathroom as earlier, cleaning her rear. The puddle of her milk from earlier was still stretched across the floor.
'What the fuck even was that?! Am I shitting like a cow now too?!' she thought. Lucy finished cleaning herself up. Unfortunately she'd gotten some of her...mess, on the inside of her pants during the move from outside to the bathroom. She stuffed them into the bin.
'Do I even bother going back to the exam? There are so many other things I could be doing instead...' she thought. As if on cue, her hand slid down to her crotch, and started gently stroking the small amount of cock she had left. Her other hand toyed around with her nipples, which were still sensitive after the milking. Lucy was pretty confident this wouldn't take long, she was still horny from the car ride with Mike earlier.
After a couple of minutes she could already feel it building up, as she frantically stroked her dick. The closer she got, the better it felt, but the less it felt like there was for her to continue stroking.
"Mmmm...ooohhhh..MmmOooOoohhhh...MOOOOOOO" she screamed as she came. Her cock has shrank down to a small nub she could barely grab, about the size of a clitoris, but it still spurted it's load into the toilet.
Lucy sat on the toilet for another couple minutes as she recovered, then pulled up her jeans. She wasn't even sure that helped, if anything she felt even hornier now. When she looked in the mirror, she was shocked that it also meant literally, as well as mentally. Two tiny white horns poked through her hair, not far from her new ears.
Lucy went back to the exam hall, and took her seat again. She didn't even try writing answers this time, instead focusing her attention on the exam officer, smiling at him whenever they made eye contact.
