During anal sex, the man inserts an empty wine bottle into the woman's vagina, masturbating her vaginal fluids into the bottle. Pulling out, he then orgasms into her mouth. Allowing the woman to spit the semen into the bottle, he then forces the bottle into his own anus and allows the mixture of fluids to seep in. Allow half an hour for proper absorption.
Variation: Red Andy
A Red Andy is performed while the woman is having her monthly cycle, allowing not just vaginal fluids but menstrual juices into the bottle.
