Docking bubble 

When two men preform docking and while docked, they both reach an orgasm at the same time inside the foreskin. Creating a bubble of cum and making the uncircumcised penis ballon up.

Lapp and Joey where docking last night and I heard that they created a docking bubble while still docked together. I guess his foreskin bubbled up while still attached to his circumcised cock
