Mountain Stacks

Especially large breasts.

Lady 1: Don’t worry, sweetie! This old woman will show you the way to be a proper lady!
Lady 2: Oh! Th-thank you, ma’am.
Lady 2 inner voice: ‘Does she seriously think of herself as “old” with those mountain stacks..?!’

Stroke Stack

My mom cleaned my room and she almost found my stroke stack.

Stacked and Sacked

When he stacks his testicles on top of eachother and wraps them with saran wrap to hold them in place, creating a replica of a second penis. Recommendation: Use your new ballsack-stiffy to penetrate her while also having anal sex for a double dong combo. Recommendation #2: When he can't get hard and his man meat slightly resembles mashed potatoes filled inside of a rubber glove finger, ask him to stack and sack you instead.

He surprised her by filling both of her holes after he stacked and sacked himself to create a scrotum-sword for penetrate in her punany while he also shot the club in her brown starfish.
