Intimate thumbtacks
BDSM idea by Magnuz Binder.
I spread your outer labia wide before I apply the wide band of adhesive tape between them. The sharp points of the thumbtacks on the inside, sticky side of the tape digs into your softest and most sensitive parts. I help them along by gently cupping your vulva, pressing the points harder into your flesh, and slowly rubbing the tape, making the thumbtacks scratch and shift in your flesh, intense but without piercing it. You gasp from the sensation, and when I gently pat the tape chastity, you scream from the intensity of it.
