My eyes lit up as I saw Grace's pussy getting closer and closer, until my face was buried in the vee of her legs. MMmmmmm, I was in heaven. As her pussy was shoved up against me, I stuck my tongue out and slid it right in. I wanted to taste her before I started on her clit.

I realized Chuck was still talking to me and strained to hear what he was saying; "–with my well-oiled cat, and fuck your pussy to within an inch of cumming. Your success with Grace will earn you a cum, failure will bring you retied on your back with Grace astride you, and more lashes on your front."

I smiled into Grace's pussy and began my attentions anew. I barely felt the soft strokes of the whip, but when he started to push his cock into me, I groaned into Grace's crotch. It was heavenly to be caught between the softness and the hardness, with the cat licking my backside. I had dreamed of this many times, and wanted my Dom friend to arrange it with any of the other Doms he knew; but he always chuckled at me and said it was up to the Dom who trained me to do it.

The most difficult thing for me now was to keep from cumming. The smell of the pussy in my face along with the feeling of my tongue gliding over her soft folds combined with the stroking of the hard cock within me and the licking of the cat quickly had me to the edge. I concentrated as hard as I could on Grace, sucking her clit into my mouth and rolling my tongue around the little nub of hardness. I could feel her thigh muscles trembling and I knew what I was doing felt good to her.

Again, I stroked my tongue within her, tasting her as I used my nose to rub her clit. I alternated back and forth, sucking her clit, flicking it with my tongue and then lapping her pussy like a thirsty dog drinking her nectar. She was starting to roll her hips around on the bench and I was struggling to keep up with her. The cock was continuing to slide slowly in and out of me, stroking the walls of my canal. Knowing that Grace was so close to cumming combined with the other sensations once again had me to the edge. I groaned deeply, trying to hold back my own orgasm. I knew that I might be able to hold back if Grace came, but if that cock within me erupted, I too was going to go explode.

I sucked Grace's clit within my mouth again and remembering that Chuck told me she was a pain slut, I bit gently on it, scraping my teeth against it. That was all it took. Grace's hips jumped off the bench and she grabbed my hair and ground into me as she cried out and came into my mouth. It was indeed nectar. Her release was sweet as it slid down my throat.

As Grace flopped back and let me go, I cried out, "Please sir, if you don't stop I will cum. I can't stop it. I'm trying, but your cock and the whip - I just can't stop. Pleeeeeaaassee!" I was clamping down with my pussy, as if I could hold it back that way. I was at the pinnacle, floating along the edge. If he didn't stop fucking me, or if the cat hit me extra hard, I was going to cum no matter what. There wasn't anything I would be able to do to stop it, and my fear was that he would think me unworthy and caste me aside.

Chuck surprised me. He struck me hard three times in succession then tossed the whip aside. He grabbed my hips and started slamming his cock into me, making the wooden bench I was strapped to creak in protest. The hard strikes from the whip tossed me over the edge. I was tumbling down, seeing stars. My body was nothing more than a grasping pussy, spasming around Chuck's pounding cock. I was wailing in relief at the explosion, my face still damp from Grace and my hair bunched up from where she used it as handles. I'm sure I looked a sight, but at that moment, I didn't care.
