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"
When you are supposed to be having a hot threesome but the other two participants are giving you zero attention whilst humping at each other like no tomorrow
Dude, even if somehow you finally managed to get Kirsty and Stacey into bed at the same time, it'd be a lonely threesome for you mate.
