sexual act where the penetrator has intercourse with a partner who keeps their underwear on. If the partner is a woman, granny panties
are used. If the partner is male, tighty whities
are used. In the act, very little effort is made to clear the underwear from the desired orifice. Most prefer to force their way through the underwear or, in their lustful thrusts, to stuff the underwear into the partner, not unlike stuffing a plush toy.
