Sealing the Envelop is to get a female naked and passed out drunk, at which point you masturbate and ejaculate semen down her ass crack using the tip to spread it evenly, then with both hands clamp the cheeks together and wait for it to dry, next day when she wakes up her asscrack will be stuck together.
