Surely a little anal experimentation will cure her fantasies

Her thoughts were out of control, Cassie needed to head back to her room, relax, clear her head. She decided to blow off Chem 101 - it was a giant lecture half the class skipped anyways.

Her guilty conscious tugged at her but she hurried back to her dorm room, trying to tamp down thoughts of Hector manhandling her, bending her over, piercing her little pucker with a cock way too big for it, making her scream in pain, in pleasure...

What the hell is wrong with me?

Back in her room she sat on her bed and tried to decide what to do. Anal was disgusting, and probably painful, why was she thinking about it?

Maybe that's the solution - a little taste of reality and I'll stop thinking about it.

It made perfect sense, play with her asshole just a little bit. See if it felt good (It definitely won't, it's gross!), and forget all about this.

Cassie dug deep in her desk drawer and finally found her almost-never-used little chrome lipstick-sized vibrator, the one her older sister had thrown into her luggage with a note about how she'd need it if she kept never going on dates.

She locked the door (though she had no roommates likely to come in), and then stripped naked, except for an undershirt. She paused to look in her mirror, and for a moment fixated on the smooth curve of her ass. She imagined men looking at it, staring at it on the street, hungering to spread her immaculate cheeks and start violating the hole between them. Her face and chest flushed at the thought, her heart beat faster.

Oh god, I have to get over this.

She sat on the bed, propped up on pillows, legs back near her head. She took the little silver vibrator and, hands shaking, touched it to her asshole.

The tingle of sensation was novel but pleasurable, so unlike the feeling of masturbating her clit (not that she did that very often), while at the same time still making her pussy hot and wet. Without consciously realizing it she started pressing harder, craving more of the sensation, rapt with excitement at the first touch on her virgin asshole.
