Aggressive nutsack sniffing
The most kinky thing one man can do. Aggressively sniffing nutsacks requires skills and technique and proper form. You have to keep the ball hair from going up your nose but still be able to blow around that hairy sack with the sheer force of your breath. Try not to sniff too much cheese all at once. And like DJ Khaled once said, “Life, is Roblox”.
Aggressive nutsack sniffing is my favorite activity to do on your grandma.
