When a woman inahales a large amount of smoke from a bong and holds it for a minute. Just before she exhales, you shove your dick deep into the back of her throat, blocking her airway, so she can't exhale just as if a chimney was clogged.
My gf wouldn't go past 3rd base, so I gave her a chimney clog till she passed out and made her go all the way without her knowing.
