RTM
Rag to mouth sex.

When a girl on her period gives you a blow job after you've already fucked her and without ever washing the blood off your penis.

See ATM
Last night that girl was so drunk and horny, she forgot she was on the rag and went RTM with my dick covered in blood. She cleaned it right up.
