"Jack me off, Mom, do it real fast."His finger went into high gear, and so did her fist. While Donna's hand zipped up and down the massively engorged ...haft of her son's cock, Matt pistoned his stiff middle finger hard and deep in her steaming cream-filled pussy. Wantonly, she hunched her hips up and ground her clit against his hand, desperate for even more delicious sensations.Within seconds, a body-wracking orgasm erupted in the smoking depths of Donna's cunt and thundered out to shake her. I told him that I'm sure it was fine and not to be worried. He asked if we could see who is bigger. Reluctantly, I agreed.We both stood up off the couch and pulled down our pants, I was wearing some loose comfy boxers. He was wearing tight Calvin Klein briefs which made his bulge look huge. I told him that there is no way that his dick is smaller than mine, then, we both took off our underwear to compare. He was right, his cock was a little smaller than mine, only by half an inch or so.. I felt his fingers and the cool pool water touching my pussy and almost came right away… I pulled away from the kiss and hid my face, embarrassed at my reaction. But the next moment, I felt him slide his finger inside me. "I'm going to cum if you keep that up!" I told him. He smiled. "I'll have to do something about that," he replied, as he carried me to a slightly shallower spot in the pool. I felt his hard cock right at the entrance to my pussy. I gasped—and he pulled me into another deep. Tentatively, nervously I reached down and pulled my short blackskirt up a bit, revealing the smooth front of a pair of tiny whitepanties. "It....it...it's gone..." I whispered as I reached to touchthe smooth void that had apparently replaced my manhood.Upset, I slammed my new skirt back down onto my thighs and stompedaround angrily on my new high heeled boots. "This can't be happening!"I raged. What could possibly explain this? How had this happened? Why?Who could have done it?Then it hit me..
