Blanket bsf

A blanket bsf is a MF that you could cuddle with because their blankets smell like piss juice. A blanket bsf could also be someone who u talk so much shit about but the “blanket” is covering all of the sneaky secrets...
A blanket bsf could be someone who you want to finger you under a blanket 😩🤚🏽.

Bsf 1: ou bsf your blanket smells like piss . Lets cuddle
Bsf2: yeah.. now I am your blanket bsf,

Bsf: finger me under the blankets. 🖖
Bsf2: okay.. I’ll become ur blanket bsf.
