My wife knew at the time that I had an anal fetish because I would walk around the house nude with butt plugs, anal beads, silver bullets, anything that would stay inside me. Sometimes I would leave it in while having intercourse and she would reach around and feel it, a very exciting sensation!
One day she was being lazy about having sex, so I took matters into my own hands. After walking around the house nude for hours with several different anal toys in my ass, I snuck off to the guest room to play with myself. I lubed up an eight inch realistic dong, knelt down on the end of the bed, and slowly sat down on top of it.
Shortly afterwards inserting the dong in my ass, my wife opened the bedroom door and stood at the doorway. She saw me kneeling on the end of the bed, the dildo hidden by my thighs, so she thought that she would just stay and watch the show, giving me encouragement and making small-talk because she knows how much I love to be seen nude and also watched by others while I masturbate.
The thought of being caught with the large dildo in my ass was very scary while exciting to me, as my wife had never seen me with such a large object in my ass before. My 5" cock was rock hard and pointing upward as I leaned back on my hands, totally exposing my oily and shaven dick and balls for my wife's viewing pleasure. Little did she know that I was pleasuring my anus with the stretching sensation of the monster dildo, over 3" in girth, it felt like I was on top of a porn star's massive cock. I would alternate stroking my stiff cock furiously for my wife for several minutes, then lean back on the giant dildo, taking it all the way inside my rectum, until I could feel the realistic balls pressing against my balls. All the while, my wife was oblivious to what was really going on behind the scenes.
Becoming aroused beyond the point of caring, I began to quicken the pace on the dildo. Seeing me rising up and down so quickly began to make my wife more curious. She asked me why I was doing that, and I told her that it felt great. Finally, she had to walk into the room and look behind me. Seeing the large shaft between my legs and the head end disappearing into my ass made her gasp! She was speechless for minutes as I continued riding and jacking myself. She asked, 'how big is that thing?' So I raised up a bit and let the head come out of my anus slowly. She just stood there and stared at the greasy dildo and my now gaping ass.
I was about ready to blow my load, so I changed positions to the end of the bed, lying on my back with my legs up in the air against the bedframe, legs spread wide. I reinserted the dildo in this position, began stroking it in and out while stroking my cock with my other hand over my open and waiting mouth. My wife knew exactly what I was about to do, so she just stood there waiting and watching. A large explosion of cum shot straight downward into my mouth and my lips. I moved down to the side of the bed, removing the dildo and just holding it in my hand, with cum dripping from my chin we sat and she made comments about how horny I had been.
