Dads sex slave Jan

[i]I was 5 when my mom died and a year later my dad remarried to Jan.She was 17 then and was concidered the hottest girl in town.When I turned 13 my dick swelled up and dark curly hair began growing around my crotch including on my balls whick had doubled in size.I began jacking off all the time and one night I became really excited when I heard my parents bedsprings squeeking. My cock grew rock hard so i jacked off while listening to my dad putting the dick to my step mom. A few years before jans doctor had told her that she was unable to have kids and since then my parent rarely fucked. They would fight about it all the time and it usually ended with my dad calling Jan a frigid bitch and him storming out of the house to his favorite bar. One night after a really bad fight my dad went to the bar and Jan sent me to bed early .I was really horny that night so I snuck into their bedroom to borrow one of my dads fuck books. I figuered that since Jan was doing the dishes I would have plenty of time to thumb through his books and find a really good one. I was wrong because a minute later I heard Jans foot steps coming towards their bedroom. I quickly hide in their rooms huge closet and as soon as entered the room she began taking off her clothes. When Jan had removed all of her clothes including her Bra & panties I could’nt take my eyes off of her big titties and hairless pussy.My dick grew rock hard and I stared at her until she had put on her nightie. Before getting into bed Jan turned on a small light so my dad would’nt trip over anything when he got home from the bar. It was’nt long before Jan was snoring and I was about to sneak out of my parents room when I heard my dads voice downstairs. My dad was’nt alone either because I could hear 3 other male voices with his and they were getting louder. The next thing I heard was a loud crashing sound of the french doors of my parents room slamming hard into the wall. My dad had flung the doors open so hard & fast that the doornobs had lodged into the wall. My dad and his 3 buddies rushed into the room and before Jan knew what was happening the four of them had tied her wrists to the bedposts and stuffed a sock into her screaming mouth. When Jan had been secured my dad stood at the end of the bed and in a drunkin rage yelled,” Im sick and tired of you telling me no you fuckin barren ass bitch so tonight we are going to show you what that tight pussy of yours was made for”. With that said the four men began to undress and I realized that I knew the 3 guys from the last hunting trip I went with my dad. Kent , Sammy and Jimbo were my dads best friends and when they had removed their clothes I could’nt believe that they were going to gang-rape my step mother. I couldnt help but see that my dad Kent and Sammys cocks were about 6 or 7 inches long but when I looked at Jimbos crotch I was truely amazed because he looked like he had an elephants trunk hanging between his legs.
