My husband loves to tie up my balls. Fortunately, I love getting my balls tied up.
That said, I like to keep some mystery, so the details are private. But you can still enjoy it.
After he was done with me, he tied me in an impromptu body harness. He left some wriggle room for my hands. He then laid on his back, had me straddle his chest and ordered me to work on his nipples until he came. That was fun.
