Muscle Explosion 2 (2006)

Five more famous models, centerfolds, and fitness stars go all the way in the workouts you never though you'd see! Their most intimate and private moments. Fresh from the pages of magazines like Playgirl and Men's Workout, these hot young Sharpshooter hunks strip down, pump up, and work every inch of their tight, ripped muscles to an erotic explosion you'll never forget. Five different private sessions that were previously included as alternate endings in recent productions - now offered in a convenient package.

Unfortunately the movie Muscle Explosion 2 is not yet available on HBO Max.
