Sadists aggressively fuck bound slaves, pinching their nipples with clothespins

It's no secret that the nipples of girls are one of the most sensitive areas on the body, therefore, caressing them during sex, you can easily bring any chick to the most excited state. But during BDSM sessions, the masters twist the tits and nipples of the slaves to give them pain and bring them into a state of discomfort. Looking at these bound masochists, who are also stretched into the pose of a star, stuffed into wooden boxes, you might think that they have enough unpleasant sensations without clamped nipples, but the masters will not agree with you and during aggressive fucking in the cunts and mouths, they clamp the tits with clothespins
