To masturbate while wearing a pair of worn unwashed panties over your head, with the gusset over the nose - so you can inhale all the heavenly glory.

Correct positioning of the leg holes either side of the eyes enables visual stimulation to be used as desired.

If the panties are heavily soiled with anus debris the act becomes known as a ‘Smelly Venom’.
