Wait, balls in is a literal term? Shit. Welp, I'm gonna have to say balls deep is pretty fucking fantastic. But balls in.. Idk, seems like it might hurt.
I saw a porn where a dude stuck his left nut in a girl's butthole and he popped it out, looked like it hurt. No thanks...
if shes tight that shit would hurt lol... if shes loose.... hellyeah im dipping my WHOLE package in her bowl.
What if she flexes her pussy as soon as you get both of them in there? It'd be like some sort of bio-iron maiden for your package.
by the time im done im in up too my nipples. getting out from there is a lot like being flushed down a toilet in reverse
If I managed to get both my entire dick and nuts inside of a chicks vag, I might consider her too loose for my tastes. Even if I had to shove them in.
