Sex Belly

Painful condition experienced by female after having sex with a very well endowed male. Typically occurs after the man with a huge penis penetrates her so deep, (usually doing the "doggie") that it changes the positioning of her internal organs, resulting in discomfort that can last anywhere from 24 hours to several days.
