When you watch Catherine Crystal take on two guys at the beginning of Bi-Ceps, what you actually have is a three-way guy scene, since Crystal used to be a man. This scene sets the stage for a plentiful array of sexual encounters, with no story linking them.
Straight sex, lesbians, gay sex, two guys/one girl, one guy/two girls, to on two in a garage... and everybody does everybody else. For the most part, the acting is brutal, and you wouldn't use the word erotic to describe this sexvid either. In fact. the best scene is a lesbian number between Lois Ayres and Melissa Melendez.
I've seen just about every bisexual video on the market and Bi-Ceps is fair by comparison. Some of the guys have good looks and others, well, look about as great as they act. A few of the female cast are of the all-star variety, however the scenes seem slanted toward the all-male market.
Finally, the video quality is also only average, with some awful edits that seem awkward and a few places where the actors look for direction. Director Roger Earl would have done better to add a story to the proceedings, because Bi-Ceps ends up being a collection of disjointed sex scenes, only a couple of which work.
