Anguish blended perfectly with pleasure, and at that instant, the great surge of sensation sent me into the place only sex with a true lover could fin.... I began to come, my cunt clutching greedily at the pumping fist, while my nipples burned and throbbed like erupting volcanoes.Margaret grasped a peg, and as I peaked, she tweaked. My body jolted in spastic convulsions. I squirted into her face. When the second peg was pulled off, I half-fainted. Coming back to earth, I found that I was still. Eventually, with some awkwardness and a bit of giggling, she got the idea and straddled my prone body. I had to guide myself inside her until she got the hang of gyrating her hips and grinding her sex into mine. She knelt up, supporting herself with her hands on my chest. Running my fingers lightly down her back made her shudder as she set the pace. Her eyes were closed as she revelled in the sensations our bodies were giving her. She took the time to experience each new delight while keeping. It didn't feel awful, yet I found myself repulsed by the act all the same, pulling myself back from it. Reading his face, I saw a mixture of amusement and frustration. That frustration saddened me – a sign of my poor service. My resolve redoubled. I leaned in again, licking his cock this time, slowly, from base to tip, exploring every curve, enjoying sensing it harden further, enjoying the knowledge that it was arousing him, that I was performing my function as toy and slave. I wanted- no,. He started thrusting it in an out and this was driving me crazy. He was so strong and determined. He was in total command; every probe with his huge fuck pole was so deliberate inside me. My prostate was being repeatedly probed as he thrust and out of my bottom.It was otherwise quiet in the room but as he quickened the pace the headboard started banging against the wall and you near a slurping sound as he pumped me with his huge 'piston'. I was groaning out loud as I felt a huge sensation.
