Yoga instructor Carrie's orgasms are streached to their limits...

Carrie never thought she'd see herself twisted up like this in the studio mirror. She's roped to her own exercise bar, legs splayed, body stretched so tight her muscles shake. A thick ball gag cuts her breathing down to short, wet grunts. The ass hook buried in her holds her posture ramrod straight; every twitch tugs her open. Two buzzing dildos grind into her—thick, relentless, set on high—while someone tweaks the ropes until her spine arches and her toes barely brush the floor. She strains, slick and trembling, every new "pose" pulling her further apart, and there is no mercy in the next adjustment.
