Jen decided her brother needed no help from her today. Not to mention the fact that if they fucked while she was in her werewolf form, they'd both shift back in front of the students, which would only make things worse.
Jen hugged the wall, creeping slowly along it, doing her best to avoid the screaming students. She was about to round a corner when she was slammed to the ground violently from behind. Her brother had leapt on her, pinning her to the ground. His hot breath was on her neck, and she could feel his beast-member rubbing against her, instinctively looking for entry.
Jen felt her temperature rise and her pulse quicken.
So much of her WANTED to raise her hindquarters in the air and join him, but she couldn't let him trigger her here. Jen fought against the beastly lust that was quickly overtaking her senses, but it was quickly turning into a losing battle.
"Please....noooo," she whimpered, hoping for a way out.
