Careena Collins made her 1985 porn debut in Snatchbuckler. She signed an exclusive contract with Western Visuals, doing many top videos for director Jerome Tanner. She also starred in the Dark Brothers' The Devil in Miss Jones 3 and Alex deRenzy's Babyface 2 before dropping out of hardcore in 1988 to go to college. After graduating with a 4.0 grade point average, she entered law school and eventually graduated at the top of her class. Contrary to myth, she did not pay for her education through her porn work, but by the more prosaic means of checking groceries and taking student loans. During these eight years, Careena also did various S-M videos, most notably Power Play, The Face of Fear, Dark Interludes and The Mystery of Payne from Bruce Seven Productions.
Careena returned to porn in 1994. "…Collins has earned her spot in the X-rated Hall of Fame with some unforgettable anal sex performances," writes AFW, "most notably as a human toilet for Rocco Siffredi in Kink. It stands out as one of the nastiest porn scenes of all time." Collins, who on her porn debut was so nervous that she threw up, stars in Buttslammers 9, Crazy Times, and Taking It to the Limit 2,3,5,6. In a famous scene in Limit 3, she gets done up the ass by blacks Sean Michaels, Julian St. Jox and Mr. Marcus while hanging in a cage.
