Velvet Sack

A soft, smooth, shorn scrotum.

Rachel loves my velvet sack.

I teabagged her with my velvet sack.

It’s a lot of work maintaining my velvet sack. If I don’t I’m like a Sasquatch down there.

hard sack

when you go at it so hard that your balls get hard as well. the thrusting & smashing that goes on for hours becomes so exhausting. you stand there, in & out. when you finally release your steamy, hot, cum it shoots through that pussy & that shit becomes a flapper. the moans are immaculate, echoing off the walls around you. after this type of orgasm your nuts will never be the same. & the chick you smashed will have a grandma cooch for life.

zoe: dude i smashed andrew so hard last night, he gave me a flapper! turns out at the end of that, he had a hard sack!!
theodore: mmm

Lumberjack Sack

When a man's scrotum is so hairy it resembles that of a Lumberjack's beard.

You have a Lumberjack Sack, it looks like the Brawney paper towel man.
