Samantha couldn't watch the movie until the end, as she saw the time and realized it was getting late. As she had class the next day she went to sleep so she wouldn't be late.
The next day nothing felt strange, she had even almost forgotten the discussion about those pills the night before. She woke up, got dressed and went to school normally, but in the middle of class she started to feel awkward. First it was just a slight discomfort in her breasts, which felt a little tighter inside her bra, and then she started to feel horny. She tried to pay more attention in class believing that you would distance her thoughts away from anything sex-related to see if it happened, but it didn't work and she kept getting more aroused.
At lunchtime Samantha couldn't take it anymore, she went to a bathroom where she locked herself in a stall, where she took off her panties, lifted her skirt and simply started masturbating. She knew what she was doing was wrong, but the boner was just too much and she needed to do something.
While masturbating Samantha felt that this time she was feeling different from all the other times she masturbated, as it wasn't just her pussy, but her entire body seemed to be much more sensitive.She had to be quick at this, so she did everything she could to come fast.
Before long Samantha came, she doubled back during her orgasm and covered her mouth to keep herself from moaning and drawing the attention of anyone who was nearby. It caught her attention that her orgasm was more intense than usual, but she was totally surprised when her mouth suddenly filled with something that rose in her throat.
Thinking she was vomiting during her orgasm, she bent over her knees and opened her mouth. Samantha then paid attention to the taste that had been in her mouth. She remembered what it tasted like, but couldn't believe it was what it tasted like since she was alone. She then took a closer look at what she had thrown up, which left her no doubt about what it was, but left her more confused as to how it could have gotten there.
"I can't believe it, this is cum. But how is this possible? I'm alone in the girls' bathroom and I was covering my mouth, how is it possible that I had cum coming out of my mouth?" Samantha asks herself quietly so no one can hear her
