Threecret
A threecret is a cross between a threesom. And a secret. Its a threecret when one or two of the members dont know its a threesom.
Dude i was in the middle on the couch, and I was fingering the girl 1 on my left and the girl 2 on my right was jacking me off. We had a blanket over us so both girl 1 didnt know that girl 2 was jacking me off, and girl 2 didnt know i was fingering girl 1. What can we call it???, what about a threecret?
