(v.) Sean-ing
A sexual act akin to docking, but one partner is a female with a strap-on dildo. The dildo is inserted into the male partner's foreskin and rubbed about on his glands. The dildo is taken out right before the male reaches climax so that he has a ruined orgasm. The act is meant to bring both shame and pleasure to a submissive male partner.
