Blonde girl on treadmill with nipple piercings and cuffs

The video features a blonde girl in her 20s with nipple piercings, a metal collar, and wrist cuffs on a treadmill. She’s slim and has a ponytail. A muscular guy in his 30s with a hairy arm appears to be interacting with her, specifically handling her nipple clamps with a chain and padlock. At one point, a breast pump is introduced while she’s on the treadmill. The setting is an indoor workout room with bright, even lighting. The camera captures medium and close-up shots of the action.
