Blackmail the never ending slippery slope

I am ** year old today so in 1992 I was younger. I was living with my step dad, mother, and 3 year older step brother who was a real ass hole. In the summer I stayed home by myself while my step brother Luke and pur parents worked. One day I was home cleaning and found my step dad's porn magazines. I looked thru them nervously and then put them back in his night stand. The next day I went back thru the night stand and found more magazines, 3 vhs tapes with no labels, a vibrator, lube, handcuffs with keys, and condoms. I looked at all the things and then got a towel from the bathroom and jerked off into it. I did the laundry and went back to my chores. Around 12:30 I was getting horny again so I grabbed another towel and went back into the master bedroom. I didn't get the hustler and Cheri magazines this time I grabbed one of the VHS movies and put into the vcr and pressed play. A scene came on of some girl in red lingerie sucking a guys cock. I stripped down to nothing but my shirt and laid on the bed and starred jerking off. I was about to cum when I heard Luke's voice and then seen him walk thru the bedroom door. What the fuck are you doing he yelled as I jumped up and grabbed my underwear and pants. He said I telling my dad and you are getting in so much trouble. I said please Luke don't tell please. He then said why shouldn't I and I told him that I would do what ever he wanted to not get in trouble. Luke said ok but you have to do what I want and I won't tell. He then walked over to my mother night stand opened the bottom drawer and pulled out several peicesnof clothing he said put this and only this on in front of him. Not wanting to get in trouble I agreed and stripped down as Luke went thru the clothes handing me fishnet leggings, one pair of black panties, and a corset. I told him I didn't know how to put it on and he saidbhe would help. He unfolded each peice and helped me put them on until I was fully dressed. He then said one more thing and pulled out a tube of red lipstick and told me to pucker my lips and he put it on me. He then said go look in the mirror. I walked into the bathroom and looked. I was slightly aroused by the way I looked and loved the way I felt in those silky panties. I walked back out in the room and Luke was returning from somewhere in the house. He then said let's lay on the bed and watch the porn. I laid down on the bed and Luke did also pulling his cock out that was already hard. I looked ahead at the porn and I was rock hard so I rubbed my cock thru the panties. Luke then stood up and I seen a flash and I looked at him as he was putting down the Polaroid camera and shaking the picture. He took a picture of me in lingerie with lipstick on and my hard cock sticking up. When the picture developed he turned it to me and said if you want me to burn this you have to do 1 more thing. I quickly agreed and he said let me cum on your face. I said no way and he said ok I will show your friends this picture. I said no I will but that's it. I laid back on the bed and he positioned my face and I closed my eyes and mouth as he jerked off over me. Then as his strokes got faster I felt his cum hit my face and my chest, then I felt his cock slap my face as he squeeze the last of his cum out. With my eyes still closed I asked if he was done and he said almost open you eyes. As I opened my eyes the flash went off again. He took a picture of my cum covered face with a cock in the picture. He said I will burn the first one but tomorrow you will have to work this one off. As he walked out the door he said you might want to get a taste of that cum on your face you never know you might like it. That ass hole had me sucking him off weekly and swallowing cum and later he fucked my hole and I rimmed and sucked him.
