Hello...I am 25 years old and have a stepsister 2 years older than me named Lisa. I've outgrown this now, but when I was 16 I had a crush on her. She was good looking with long brown hair, an athletic build and huge boobs that I used to glance at when no one was looking. I was skinny and she was a little bigger than me, maybe outweighing me by twenty pounds. Most of it was her jugs, I'm sure. They were big, round, and heavy. I still sneak looks at them when she isn't watching. Back then, she had a jazz-dance class at school and would always be in leotards around the apt. I swear her jugs were so big they bulged out of her bra when she was wearing that leotard. We lived with our father in Denver, CO. We were both pains in the butt in school. My stepsister started hanging around these shady older girls who were mean to everyone else in school. Some of them were even cheerleaders, but they were mean. Lisa began staying out late at night. She was clearly in with the wrong crowd. One night, she didn't come home at all. Our dad came home early, and I had to lie to keep him from finding out she wasn't in yet. I thought she'd be in later, but she never showed. I wasn't too worried, though. I figured she try this sooner or later. I just hoped she wasn't having sex with some guy-it'd ruin my fantasy life. The next day at school, I saw her talking with three of her friends. I went over and tapped her on the shoulder. After a second, she turned around, saw me, and said, "What do you want?" Not at all like someone who had some explaining to do. I said, "Dad's wondering why you never came home last night, goofus!" I had no way of knowing if this was true as our dad always got up for work very early and we didn't see him until nighttime. "No he's not...," she said. " I called him at work this morning and he didn't say anything to me about it-liar." Oops. She had me. Her friends started to laugh. This embarrassed me. The bell for third period rang, but this was family business. I raised my right arm to point at her, "Ayy, maybe I'll just tell dad that you were out all damn night!" That should shut her friends up, I thought. My mind instantly went, "waitaminut stupid, you could get her to give you something in exchange for you keeping quiet." I had a sudden thought; if she let me feel her up, I'd keep my mouth shut. Vile, I know, but that's what I was thinking at that moment in my young life. My eyes glanced at her chest but she was wearing a leather jacket that was zipped. I followed up.. "Wellll, unless….” the other two girls grabbed me and held me up against the wall. They were both holding me tightly, and I began to feel a little aroused. After all, two older chicks were pinning me against a wall. They looked back at my stepsister, who had come back to be in front of me. "Unless--What?" she whispered. Shoot, I thought, I forgot I let that slip out. Well I sure couldn't tell her what I'd been thinking. She'd never walk around the house in those leotards again. I looked up at the ceiling, trying to think of something she would believe when-Chouff!! She punched me in the stomach! I wasn’t ready for that. Her friends still held onto my arms, and even though they were girls, they were all bigger than me. I tried to struggle, but my strength was gone and I felt a big ball of pain in my belly. My eyes welled with tears, but I fought them back. “Tell me!!" she gritted, under her breath. I looked back up at her, and realized I was getting a boner. "F- blah blah you, Lisa.." I was defiant. Was I liking this? I tried to free myself of the two girls holding my arms, But I was too weak. The girl on my left said, " He's trying to get loose" and tightened her grip. Lisa stood closer to me and said softly; "Do you want me to punch you again? Or are you going to tell me what 'Unless' meant?" now it was official. I had a hard on that could probably be seen from down the hall. I looked at her friends holding me. They were watching Lisa. They were enjoying this sight , their new disciple, taunting her little brother. Lisa startled me by faking a move where she punched me again, but her leather jacket was making that annoying rubbing noise, so she unzipped it, and let it fall to the floor. My eyes got wide. She had on her red leotard top. The one she always wore to dance class. The one that shimmered. The one that was too small for her. This was my first encounter with Spandex. I liked it. It was form fitting. And shiny somehow, and I thought I could almost see through it.
She leaned back to look down the hall again, and when she did, she arched her back perfectly. I mean, and I can't say it enough, she was huge. She had those Caroline Bissette / Sophia Loren kind of jugs that make you want to leave your wife. (or sleep with your sister) Lisa had stepped back to me. “I won't say anything, Leese, jeezus.." I had gotten enough breath back to speak. “Listen, Mac, keep your mouth shut about this and everything else I do, don‘t follow me around and don‘t tell Dad about any of this. Got it?" Just then, we all heard a woman's high heels clicking down the hall. We were about to be discovered. One of the girls let go of me and went to look. “It's Mrs. Fisher!" She whispered back. I shook the other girl away from me. I could here them all walking away, leaving me in a heap. Pain shot out of my head and stomach. I limped to class...and vowed revenge..........
