It will always get out. Don't even try to keep a secret sexual need hidden from your wife for any reason. If your fetish is strong enough to try and hide it from your wife, you either need to stop doing it, thereby depriving yourself of total satisfaction or you may as well tell her because she will eventually find out. It may happen because you get careless while thinking with your other head or maybe deep down you really wanted to get caught. It doesn't matter, she will find out.
My wife, Beth, and I (Ben) are in our early thirties and have been married for 8 years. We met in college and got married immediately after lining up careers following graduation. We were both in great shape in university and competed actively in intramural sports. I measure 6' 2" tall, and by keeping active since school, I have maintained my 195 pound weight with a 32' waist. We go to the gym together and are active on the weekends here in the Florida sunshine. My wife maintains her beach creds at 5'5" with a 34C chest and a tiny 24" waist. She still elicits leering and ogling from other men when we are out. To this day I still get a rocket in my pants just looking at her in tight or suggestive clothes.
We have, what I would consider, a great sex life, especially considering how long we have been married. We have done it in every room in the house and often go at it out by the pool in the evenings. I was active before I met her and had never received as explosive blow jobs as I regularly get from her. In bed, we get downright tantric at times with sessions lasting for hours. Her flexibility allows me to penetrate her from almost any position. But, one thing she has never allowed is ass play. Not only does she not allow me to touch her forbidden hole but she also refuses to approach mine.
Prior to meeting Beth, I had a girlfriend who loved sliding a finger in my ass while giving me head. She would massage my prostate and sometimes just coax the cum out of my balls so it would ooze out my stiff cock. She wouldn't even be touching my cock and the cum would flow steadily out my cock. She would often position herself so her face was below my oozing cock while she would massage my prostate and let the cum just flow from gravity into her eagerly salivating open mouth. I didn't know how much I was going to miss that.
Years later, after Beth and I had been married for a while, we were going at it with force when I moved, unexpectedly to Beth, into a position that, as I had hoped it would, caused her fingers to touch my cubbyhole. She immediately jerked her whole body away and screamed as though she had gotten burned by something hot. She started apologizing immediately and I started to tell her it was ok, that I like it, when she all of sudden shuddered and with a horrified look on her face spat out "arrrrggh! That was disgusting!" I played it off and tried to calm her down, but the moment was gone and she was not going to get over the trauma anytime soon. It was then I realized I was never going to be anally penetrated by the love of my life.
I thought I was fine with that, after all our sex life is robust and fantastic. So what if she won't finger me, with our love for each other and great forte to be in synch during our lovemaking, we were having some of the greatest sex of our lives. I thought I wouldn't even think about assplay. I could easily do without.
Time went by and little by little, I began to think about how nice it feels to have someone rub my prostate. My resistance to temptation finally failed about a year ago. Beth was out of town for work and I was horny so I set down to watching some porn and get myself off. The porn was hot and this hung stud was destroying a buxom blonde's pussy when he pulled back too far and slammed his 10-inch steel rod into her backdoor. The woman let out a blood curdling scream, and the guy, already being buried to the hilt, just stopped moving. The woman was cursing up a storm "Get it out! Get it out! You bastard! Get it out!", but the guy did not move. Her eyes were watering and every muscle in her body contracted making her as immovable as a rock, unable to adjust and make the pain go away. The stud told her to relax; he was going to pull it out slowly once her body began to relax.
Her eyes were red and watering and she was pissed but you could see her evaluate her choices and decide that she definitely needed to loosen up so he could remove his phallus from her overstretched bunghole. Next, I swear you could see the dawning of understanding her need to physically accept her position and begin to relax to allow the extraction of his member from her violated hole. It was as if you could actually see her accepting that the greatest pain was over and with a far-away look in her eyes she began to relax allowing him to slowly extricate his schlong from her bunghole.
Sensing this, the stud slowly began pulling his monster out of her ass. She winced and tightened back up immediately on his attempted removal. When he had pulled back an inch or so of his cock he reached around to her swollen pussy and grabbed some juice which he rubbed onto the small amount of his tool that was exposed. He explained to her that he needed to lubricate her ass to cut down on the friction to minimize the pain as he pulled his shaft out of her. She agreed so he slowly began pushing his well lubricated cock back in her out stretched asshole to reduce the friction on the sphincter. At first she tensed up but then quickly realized how much it helped to have it sliding in or out rather than grabbing on the way out and she began to welcome minor reinsertions due to the soothing lubrication. Needless to say, you know where this went, more and more of his cock was pulled out and lubricated prior to his reinsertion to lubricate her ass until she was moaning again leading up to him pile driving her ass while she begged for more. She was in one continuous assgasm spasm and when he finally sprayed his load all over her holes (one swollen and the other just gaping wide open) she lay on the bed unconscious and shaking as though in a seizure. He collapsed on the bed beside her and got some well deserved rest while she twitched.
The scene was so hot I just had to feel something up my ass. I looked around the bedroom and spied my wife's hairbrush on the bathroom sink. I grabbed some Vaseline from the cabinet, liberally coated the brush handle with the lubrication and proceeded to force the handle in myself prompting me to cum in buckets all over the floor. I removed the brush and dropped a towel on the bed and fell back exhausted. It was crystal clear what I had been missing and how I could still get it without letting my wife know. Thus began my secret practice of masturbating with self penetration.
Over the past year the frequency of getting self granted relief increased in frequency and finally, I decided to actual invest in a toy that I would have to hide very securely in our house. I went out and purchased a 7-inch remote control rotation and vibration cock with a rubber suction cup so I could mount it as if it were a real penis. I hid it in a compartment under the bottom drawer in my bureau awaiting the golden opportunity to safely enjoy it. It seemed as though that opportunity presented itself about a week later.
A major client of mine was visiting so I had planned to spend all day entertaining the rep. We were enjoying the links when about 10:00 she (the rep was a woman) received a call that she needed to get home right away as her husband was involved in an accident. We went back to the clubhouse and she jumped in her car to head back up state. Here I was with a clear schedule for the rest of the day and Beth would be at her office until later that evening. What a great opportunity to get home.
I was home by 10:30 and had discarded all my clothes in about a minute. I went to my secret drawer, got out my 7 -inch vibrating rubber cock (with a suction cup), made sure the batteries worked and placed the cock and lube in the bathroom for easy access when needed.
I started off wanking while watching porn on the computer. I found a gang bang tube in which the woman was moaning and cumming hard from all the dicks pounding her pussy and stuffing her mouth. She was laying on her back with three cocks over her face when the guy in her pussy decided to push her ankles up and enter her empty hole. Her eyes immediately flew wide open and she seemed to hold her breath. The cock slowly penetrating her asshole was consuming all her attention. She was completely focused on the stretching of her sphincter and bowels as the cock proceeded deeper. It was like her eyes were open but she didn't even see the three monster cocks being wanked on her face. Oh my God! I wanted to be her!
