Cumplete Cycle

When you are laying on your back, with someone bouncing on your dick, and someone else that has their ass on your face, the two people on top of you are making out, you then cum so much that your cum flows through the person that is bouncing on your dick, out of their mouth, into the mouth of the person sitting on your face, it them travels through the person sitting on your face, out their ass and into your mouth and back out of your dick, completing the cycle.

Girlfriend: "Hey babe can we invite my friend over and perform a cumplete cycle

Boyfriend: of course honey, I haven't jerked off in a month so I will have enough cum to complete the cycle and travel through all three of us.
