Foot sniffing and jerk off* training
(* jerking off is voluntary but mandatory for the most pathetic losers like me)
1. Play the video
2. When SNIFF appears, inhale through your nose, keep your mouth closed (start to jerk off)
3. When SNIFF disappears and exhale through your mouth (stop jerking off)
