Flexible and inked yoga instructor Mary Frost finds herself in a compromising position when she's invited to a private session with a seemingly innocent couple. As she demonstrates her poses, she notices the husband's lustful gaze and the wife's subtle provocations. The atmosphere heats up as Mary's tight yoga pants leave little to the imagination. The couple, unable to resist her allure, persuade her to join them in a steamy threesome, fingering and licking her shaved pussy before she eagerly takes both their cocks, one in her ass and one in her mouth, in a wild doggystyle ride.
