It’s going to be a tough assignment to complete I thought, and I have my work cut out for me. Apparently Amber knew exactly what I thinking and put ...e in my place very quickly. ‘If you’re going to continue to be an ass we’re going to have a hard time completing this assignment.’ Her temper was up and she wasn’t about to take any bullshit from me. She shocked me out of my smug little mindset. I thought about the way kids in high school had treated a gangly, clumsy, 15 year old and how they. ”Mandy and I shot the shit for a little while before I had to get up and refresh our drinks. As I tried to pass between her knees and the banister of my porch she pulled her legs up to let me get past and as she did, I caught a quick glimpse of white underneath her short skirt. I quickly grabbed a couple of beers from the fridge and returned to the porch, but instead of turning my back to Mandy as I did last time, I faced her as I forced my way past her drawn up knees. Again I saw a quick. I watched as Anita’s face disappeared below the beautiful belly of her sister. Anita reached up to put her hands onto her sisters pussy, to help her lick on Tina’s clitoris.I continued to thrust into Anita’s pussy while I reached forward to massage Tina’s breasts. I could hear Anita sneaking a breath every few seconds, while Tina was starting to scream from orgasm once again. I pumped harder and harder, bringing Anita to orgasm, causing her to bite on Tina’s clitoris while I pinched hard on. She smiled and told me to sit down on the bed with her. I was in such a shock that I followed her order. "What is she even thinking?" I thought to myself. "I want to know what a boy looks like. And I want to know how sex feels like." My sister said real quickly. Her face started turning pink and she looked at the floor. I didn't know what to say or do. "Why do you want to have sex? Like I'm your brother, it's probably illegal." I couldn't help but peek at my sisters boobs and pussy. My penis.
