tied up last night

Last night Kim tied my hands to the headboard of our bed and then proceeded to tease me for at least an hour before letting me cum. I love the feeling of expectation when she teases me - playing with my nipples with her mouth then moving down my stomach slowly to my cock which by then is rock hard. She alternates sucking it, licking it and wanking it. Stopping just as she senses I'm about to cum. Never letting me go over the edge until finally I beg her to let me. My breath quickening all time as she plays and teases with me. My body arches with ectasy as I plead with her. I need to cum. Then finally she straddles me and allows my cock to enter to her. She's wet by now and I slide in and she rides me until I cum.
