You forgot about it.

I fall backwards onto my mom's bed, my legs spread an my hand holding most of the combined fluids inside my now very sensitive pussy.

With my other hand i blindly search for a towel to clean up, but in the mess of sex-toys lube and other stuff around me I grab one of the strange tear drop shaped items.

I hold it over my face and examine it a bit more closely. It is made of stainless steel that is polished to a mirror finish with a flat base. On the bottom of the base are the words "PLUG #4" engraved. It looks to be about 1,5 inches in girth.

With a little tremble i bring it to the opening of my pussy, that is still filled to the brim, and slowly push it in. After the **** my little pussy just went through it slides in easily, trapping everything inside

Satisfied for the moment and no longer leaking I sit up and think about what to try next time when I notice my phone on the nightstand with a message from my mom, saying that she's on her way back and will be home in 30 minutes.
