Give her another

You remove the hitachi from Sabrina's clit and her legs slump back to the floor as she comes down from her orgasm. Her chest moves up and down as she takes deep breathes, her legs still twitching. You let her rest for a few minutes, watching her lie on the floor, unmoving except for her post-orgasm involuntary shakes, clearly exhausted from the first orgasm.

After a few minutes, you turn the vibrator back on. Upon hearing this Sabrina tries to shake her head and you think she's trying to say "no more, please" but it comes out muffled from the gag. She tries to move away from the sound but she can't move far as her hands and feet are still tied together and to the bedposts.

You grab Sabrina's ankle and pull her back towards you as she starts shaking her head more rapidly, pleading for you to stop. You jam the hitachi, on full blast, back onto her glistening pussy and she screams into the gag. You almost feel bad, you know the intense stimulation must be so painful on her sensitive lips.

You let off for a moment with a better idea. Sabrina seems to think you're letting her have a break and flops motionless again, sighing in relief. You grab the rope and proceed to tie her thighs together, Sabrina unsure why you are doing so.

Then, with some effort you jam the hitachi in between her thighs under the rope. In this position, its impossible for her to get away from the toy and you turn it back on. Sabrina starts thrashing around, trying to get the wand away from her pussy, but it is jammed against her clit and she cannot escape.

Sabrina thrashes about for a minute, screaming into her gag in pain and pleasure, her face flushed red, her body straining against the rope bonds. She begins to tire out however and after a little, she's reduced to moans and tears. Her orgasm hits her suddenly and unexpectedly and her legs spasm, her back arching as it rolls over her.
