Erin had unpacked from class and was reading at her desk with her dorm room door open. She saw Jess hurry past and vanish into the stairwell.
Minutes ticked by and Erin grew increasingly concerned that Jess had just dumped Kat in her room and hurried off without staying a bit to see if she was OK.
Erin got up and walked down the hall to Kat's room. After knocking repeatedly, she opened the door.
Kat was in her bed completely twisted up in the sheets. Facedown with only an arm and her back exposed, she seemed oblivious to her visitor. Erin could see the covers moving slightly with a repetitive motion.
Erin noticed a smell in the room, a sweet smell that she couldn't quite place. Taking it in, it reminded her of honey and lavender.
And sex.
There was a definite musky sexual component underneath the more wholesome aromas.
Following her nose, she found Kat's t-shirt in a ball behind the door. Inspecting it, she found a huge purple stain. She brought it up to her nose and took a deep sniff. It was heavenly, her tongue came out of its own volition and licked the amethyst wetness. A loud moan escaped her lips and she flopped to the floor, her bulk pushing the door shut behind her.
This caused Kat to stir and sit up.
Erin was confused for a moment as she didn't recognize the girl in the bed. This girl had no tits and the Kat she knew had DDs and wasn't afraid to flaunt them. The hair and eyes were all wrong as well.
Kat locked eyes with the girl propped up against her door. 'Its me Erin, I've just found something amazing. Something that is perfecting me. I'm not done yet, but I can still share. I think this will be the best thing that ever happens to you'.
Kat stood and sauntered across the room. Erin could see her hands were coated in the same purple substance she had found on the shirt, and the source of it was her bare oozing slit. As Kat walked, her knee length mane swished behind her as her generously flared hips swayed with every step.
Kat extended her hand down to Erin. Numbly Erin took her hand and allowed herself to be guided onto the bed. Kat vaulted her and forced her dripping pussy into Erin's face. Erin was fully under the spell of the femboi-to-be's pheromones and began to enthusiastically try to lick up every glistening purple drop.
Quickly exhausting what was available on Katrina's skin, she probed the redhead's pussy. She was rewarded with more of the delicious liquid but also found a rounded obstruction just inside. Kat twitched with pleasure as Erin's tongue explored the mysterious mass. Quickly Kat moaned and a jet of goo blasted into Erin's mouth.
Kat flopped to the side, pushing Erin off the bed. Erin's world grew foggy as she sat sprawled on the floor.
Kat rolled over to where she could see Erin's prone form. The Russian girl was still ravenously hungry but also was filled with contentment. Time seemed to speed up as she watched the infection go to town on the chubby girl.
