When you take care of another cock, getting more and more horny, without being able to get an erection through the cock cage... which makes you even hornier... and to hope that - if not your cock - at least your balls are are taken hard... that can be very very horny! Even if you kneel and present your boy pussy and let it finger (or more), a locked cock between the legs is very horny. 😍
B D E F G ahh fuck it, I would try them all.
My exwife and exgf used to grab my sack and squeeze them so they were together, then twist them until I grunted. Sometimes she would squeeze the skin above my balls making them pop up all shiny and tight them suck and bite them, but I got so agitated by this my exgf used to tie me down to have her "playtime" as she called it. We have even done this outdoors with me tied up so she can pull down harder, stretching my scrotum to the point of me crying out, but because we were outdoors I couldn't in case we alerted passers by
