She goes deeper than she means to.

Cassie's chest heaved in pleasure as she kept pressing the vibrator harder into her asshole. It's only subconsciously that she realized her little rosebud is slowly loosening, opening.

Oh god my body wants to be penetrated... I thought only sluts liked anal. Am I a disgusting slut for this?

She pushed the vibrator in, just a fraction of an inch deep at first, her little ring clinging tight to it but slowly, slowly, allowing the narrow thumb-width vibe to go deeper. Each fraction of an inch felt better. Not just more pleasurable but more right.

I'm meant to be filled. My asshole is meant to stretch and have it feel sooooo good.

The thought flitted through Cassie's head; she didn't even register that it wasn't truly her own. Instead she just pushed harder on her asshole with the tiny vibrator, sparks of pleasure radiating through her, her pussy growing wetter than it had been in months, her focus narrowing in on the taboo sensations she felt.

At first she didn't quite know what was happening - this was so different from how she normally got herself off - but as pussy and anus started to spasm involuntarily she realized she was on the brink of anal orgasm.

"Yes, yes, YES!"

Her grip slackened and with her asshole's last involuntary clench the vibrator slipped from her fingers, inside her.

Reality hit her, panic overriding the relaxation and afterglow of her orgasm.

Oh God, I'm going to be one of those freaks who has to go to the hospital to get something taken out of her butt. I'll be a laughingstock. Oh God! Wait, wait, wait. Don't panic. Just stay still, breathe deep, keep calm.

She did just that and slowly started trying to **** the vibrator out. She could feel it was just inside, almost reachable, certainly not deep in her... But she couldn't quite **** it out.

I can do this... I remember seeing some fetish site about gaping, could that help? Or maybe I could go to Steve for help... Wait, why would I got to him??? No, I can trust him. Yeah, I just have a feeling I can.
