ball slapping?

[Fickloch]

ok so i never imaged this would happen. my fuckbud and i bought this rad new double ended dildo so we can go ass to ass ( a big fantasy after we saw it in a porn ). when we used it though we found that our balls slap together on the back-stroke and it actually hurts (not in a good way). he has much bigger balls than me so my sack takes the bulk of the abuse. apart from this the whole thing is really hot, or it would be if it wasn't for the blows to my ballbag.

i'm thinking about maybe taping our lolly bags up to our taints, but that's gonna be nasty pulling it back off the scrotum. he suggested putting a sock on the sack with like a rubber band around the base of the nuts ( very loose band ) to give some cushioning for the collisions. any other ideas?

Jockstrap?

I like the ball slapping, a little ball pain helps center me.

Jock or sock should do the trick.
