The certainly look big. Never seen a person measure their balls before... any pics of them just hanging in their natural state?
I like having them. I also like fucking with them feeling the dangling nuts slap the belly or butt as my cock is in the pussy or anus. Or instead of the girl having to smack her clit as she is getting fucked in the ass, my balls do the slapping. Occasionally I vaccuum pump them if my sex partner requests it. I gladly pump it for 3 hours and let her service the melon sized nuts.
