Sex position

[Silvio]

I need your help, guys. I once heard about a sexual position in which the top inserts the balls along with the penis inside bottom's hole.
First, is it possible? If yes, in which conditions?
Secondly, do you know any videos/images/guides of how is it done?

Thank you for your support

if the bottom is open enough, then yes….you can put a hand in or two...so you could get your balls in with enough effort
