Ass crack
From Voyeurweb's Wiki about Sex
The ass crack is the groove or crack between the buttocks that runs from just below the sacrum to the perineum, so named because it forms the visible border between the external rounded protrusions of the gluteus maximus muscles (also called cheeks). Other terms used for ass crack: buttcrack, bumcrack, anal cleft, arsecrack, asphalt, asscrack, carpenter's crack, coin slot, builder's bum, plumber's crack, credit card swiper.
When the panties move up the ass crack naturally (customarily an outcome of the formula [bodaciousness + tightness of lower garment + degree of physical activity]) , it is clinically termed "ride-up", as opposed to a "wedgie", which is usually attributed to a bullying or prankish second party. When the panties become caught in the ass crack in the process of removal post ride-up, as in posing for a VW sensual Contri, the term is, logically, "ride-down".
A nice and sexy ass crack can be achieved through physical activities, massage and ass crack auto-stimulation. Ass crack auto-stimulation is easy: Lie flat on your belly, put a vibrator between your ass cheeks and turn it's vibrations on to full power. Train for 20 minutes every day and after less than 3 months you will see that your ass crack has turned into a sexy card swiper. You now own something called a "tight ass".
Inserting a penis into her ass crack is called butt crack sliding.
