I didn't waste time contemplating it. I howled and hugged him from below when his firm, lapping tongue drew a double orgasm from my clit and hairy lip...."I LOVE YOU!"In the middle of that night, he dragged me into his bed, and placed a warm, furry paw over my naked torso. He spooned me, his relaxed sheath tickling my butt. I slept wonderfully!In the morning he made me suck him off, and my tummy got a full dose of his unappetizing semen. I would have lain in bed, waiting for my stomach to settle,. Even as the last pulse of pleasure was squirting my seed against my sister bottom, I knew that the thin material of both of our pajamas was now very wet.My sister never realized what I had done to her that first night. Again in the morning, just before the light of dawn, I fucked her bottom one more time and by now I knew that the material of her pajamas over her bottom must have been soaking wet.When she got out of bed about an hour later, she kept pressing the flat of her hand against her. PLEASE!" SAY 'I AM YOUR OBEDIENT SLAVE AND I LIVE TO PLEASE MY MASTER'" I yelled, then put my mouth up to her ear again and pulled the ropes very tight. "Or you die...right here...right now...you will die!"I was not going to kill her, but she didn't know that."I... am your obedient slave and I live to please you!" she barely managed to squeak out, messing up the line. It was close enough.I loosened the rope but kept it around her neck. She took several large gulps of air and panted. Wearing white heels, white thigh high stockings, with a white lace thong and bra she projected an image of both purity and the possibility of activities not so pure.The dancer rose from Dominic's lap. Facing away from him, she straddled his thighs and bent at the waist displaying her barely covered bottom to him. Dominic's hands roamed up and down her back, pausing only to release the hooks of her bra and slip it off her shoulders. She then pivoted to face Dominic, placing a leg on either side.
