Uncut might be fun if you want to dock your cocks together. Also the anticipation of that cockhead poking out from behind that foreskin as it gets hard. You do know that dicks have a ticklish head.
Don't stop now. No one likes a quitter. Start with a well greased tip pressed up tight to your bung hole. Remember the first thrust is the deepest. Once that massive is cock is buried up to the balls in your ass you will ask yourself why did you wait so long.
Doesn't want your pussy! Does a dog want a bone? A cat doesn't want catnip? A crack whore crack? He wants your pussy like a blind man dreams about seeing again.
It will give you pleasure as he pumps his pecker between your breasts as he plays with your nipples. If you're lucky you might even get some jewelry like a pearl necklace.
Whatever trips your trigger. If it makes you happy and horny go for it. Find a way to stick a conversation with your wife about your extracurricular activities. Hey you never know what the stranger in your bed enjoys if you don't talk. Just don't stretch your cock too long or or it might be a foot long but thick as a pencil.
