Last night I masturbated while sitting on a dildo. I picked out a dildo that was about the same size as my cock and had a flat base. After easing the dildo in and doing some stroking, I pushed it in all the way until the base was against me. Then I sat up on my legs and lowered myself down until my ass hit the bed. I had the dildo all the way, over 6 inches, into my ass. My cock was straining from the pressure against my prostate. I began to rock on it as I stroked my cock. Precum was flowing out constantly while I lightly moved up and down on it. It was sending shivers through my body and body rushes like never before. My orgasm was building and there was no stopping it at that point. I went with the flow and enjoyed the waves of senstations as I began to peak. Woah!!!! My orgasm built from deep inside and I began shooting cum in huge spurts into my palm. Each time I moved on the dildo,another powerful ejaculation followed. I came so much, it was overflowing my hand. I quickly lapped it from my palm and enjoyed the unique taste, then swallowed. I still had the dildo in my ass and my cock was still rock hard and dripping cum as I squeezed on the dildo. I eased off of it and I felt like I could float away.
