I strongly recommend you to do it - it's an unmissable, unforgettable experience, haha. I did a 3-way docking several times with my brothers - way awesome!!! Our Chinese foreskins stretch a long way out, so we were curious to try. It's lovely to slide your foreskins over each other's cock-heads, stretching them way, way out, hahaha - even tho we j/o-ed together many times before, this was our very first sustained cock-to-cock rubbing - it was also a little embarrassing as well as exciting the first time, cos it's way intimate, hehehe.
It's also the first time we ever rubbed our cock-heads together - and did it while still docked - on the tops, sides and esp. under. We all needed to pull our dicks down a little, cos they naturally spring up to our stomachs when rock-hard, hahaha - so unbelievably lovely to slide your foreskins all over each other's, stretch massage each other's foreskins from all different directions, repeatedly rub your acroposthion ends on each other, wanking your foreskins back and forward with your moist pink cock-heads turning red as they pop in and out, in and out of your long brown foreskins, sliding them all the way back to fully compare engorged cock-heads and way-sensitive inner foreskins, close-up - such an intimate scene, hehehe. And when we cover over each other's cock-heads, the sensation on our inner foreskins, esp. the edges of our acroposthions and ridged (foreskin) bands, the valley straight after the corona ridge, and having the ridges of two moist cock-heads sliding up and down along your frenulum - oh my god man - that's OUT OF THIS WORLD!!!!!
