Jen decided to watch her transformation in the mirror while it happened. She was excited about growing horse ears and a horse tail and even thought a mare cunt might be fun to have between her legs. Kyle knew how much she loved horses, and if it weren't for what Kyle said about her growing horse balls she would almost have wondered if Kyle was trying to be nice to her. She watched with particular interest as those balls started as small bulges and started growing, at first not quite knowing what to think about them. But as they dropped and started to really fill out large and in charge, Jen realized she thought they were hot. Without a sheath or a shaft to accompany her new horse balls, she thought they looked surprisingly girly and sexy to her.
Kyle had dared her to not try to hide her new balls, and Jen was feeling like they were a powerful statement that she wouldn't want to hide them even if she wanted to.
Jen sat down to pull up her new balls for a better view of her new mare pussy. While she was adjusting her balls she realized she was also enthusiastically fondling them and that felt so good. Even in the mirror she could see how glistening wet her larger, more sensitive and inflamed pussy was. She kept fondling her balls while moving her hand to masturbate her horse pussy.
Suddenly with great force, Jen sneezed all over her chest. It was both the phlegmiest feeling sneeze of Jen's life so far, but also by far the most orgasmicly intense and pleasurable sneeze she ever had. She barely had to glance down to realize she had just cum all over her own tits. Kyle had worded it as a punishing "vomit", so Jen was glad that the transformation and "nature" had done what it usually did and made anyway to climax and cum pleasurable and, dare Jen say it, hot and fun.
Jen thought it was so hot she'd just used her new horse balls to cum on her own tits that she pulled up the hand that had been in her pussy to rub that cum into her boobs. It didn't escape Jen's notice that she prioritized continuing to fondle her massive balls while she rubbed her breasts rather than continuing to pay attention to her mare box. It did escape Jen's mind until that hand was back at work on her snatch, though, that Kyle had mentioned something about pregnancies and that playing with her cum with the same hand she was using to work her cunt was maybe not the smartest idea. Jen's wild love of horses chimed in that it was maybe the hottest idea, though, and suddenly Jen found herself in a long fit of cum sneezes as her horse pussy tightened in its own multiple orgasms. With each sneeze she found that she was having fun projecting the sneeze further and further down her belly until she had managed to sneeze cum even onto the outside of the same balls that were originating it. This time she was intentionally scooping up her own cum with both hands to rub around and into her mare vagina. She was wondering if she really could get pregnant with a foal this way.
She also realized she was starting to picture all of the girls she knew that she'd love to eat out, discreetly sneeze some cum into, and see they too might get pregnant with her foals. Some of her worst classmates Jen knew the only warning she might give them of their possible upcoming pregnancy was the huge balls she was going to let obviously droop below the smallest mini-skirts she could find or leave tightly detailed with every visible vein in yoga pants. There were more horse cunt orgasms and horse cum sneezes as she worked through some of those images in her head.
