Squidward Threesome 

A Squidward Threesome is a BDSM threesome involving two disobediant subs, or brats, and a dom. It involves the brats disobeying the dom’s orders, expecting to be punished, while the dom punishes them for mutual sexual pleasure.

I just had the greatest Squidward Threesome, man. I dominated the fuck out of those two girls.

Lonely Threesome 

The act of masturbating with both hands. Typically alternating between them, but many variations and techniques can be utilized depending on how slutty your hands are...

Discovered after after using the Stranger so much that it lost it's luster I wondered if my old standby would be into the idea of all of us partying together. Shockingly, they were into it!! and I realized the ultimate self satisfaction is a very low point of my life:(

Did you go out last night?

Nope, stayed home and had a "Lonely Threesome"
