Greg, Jack, and Naomi stomped their hooves, drawing the attention of others in the dorm. Bethany and Kayla lived in the room next door and walked over to see what was going on; they wanted the noise to stop so they could keep studying. Other students were poking their heads out of their dorm rooms too.
Bethany reached for the door knob but the door was already cracked open. She walked in and Kayla followed her. The air stank of musk and cum. Bethany turned a corner and saw the trio of equine sex mutants. She turned to run but Naomi saw her first and ran her down, tackling her to the ground.
Kayla managed to get out of the door but Jack tackled her in the hallway. Greg ran out behind him and saw other students peering out of their rooms. They all yelled and slammed their doors closed but Greg was able to shove his half hooven hand into some blonde man's door frame. He pushed his way through and tackled him against a table.
Naomi had turned Bethany over and forced a long pink tit into her mouth. Milk filled Bethany's mouth and was held so tight to Naomi's breast she had no choice but to swallow. Her shock turned to greedy ecstasy as the changes washed over her mind and she sucked willingly from Naomi. She could feel her ass cheeks swelling. They bulged and swelled and split the ass of her jeans. Dark brown fur stuck out of her panties and a black bush erupted from her crotch to her navel. Hooves tore her shoes away as the fur covered her legs. Her fingers merged until there were three digits on each hand.
Naomi ripped her shirt and bra off and Bethany's face pushed out into a muzzle. A long black tail grew behind her. Naomi reached down to Bethany's snatch and started rubbing her, then penetrating her until she was fisting her. Bethany's vagina blackened and stretched out to receive Naomi's fist until she came.
She walked out into the hallway and saw a slutmare Kayla riding a hard horse cock, her swollen breasts bobbing up and down. Greg walked out of a room down the hall with another stallion behind him. Cum leaked down his legs, drying in his fur. Together, Greg and the newbie started pounding on a door until it broke open and Bethany and Kayla cheered them on with their whinnies.
