I placed my hands on her shoulder and pushed her back. "Wha.", I began,but she cut me off. "Do you want to fuck me?" she said with determination, her ...hest heaved from the few seconds of passionate kissing. She ran her hand through her hair and pushed it back behind her ear. That thing she did with her hair, and her hot, tight, young body was all I needed to make my decision. I did not care that she was my step sister, nor did anything else enter my mind at that moment. "YES!", I replied. She. Right? I guess not, 'Oh, sorry. Never mind I guess.' He said. I responded with 'No, no. it's all right, I just don't get guys who comment on my underwear all the time. It's cool.' He gave me a nod and a smile. And I immediately wanted on, and questioned his sexuality. 'I'm going swimming after school today, you have gym this semester too, right?' Zach said. I told him I did (even though I didn't.) He said 'Sweet, want to go swimming after school with me? Nobody else wants to.' I said that'd be. "I hope you’re going to like this darling as everything I've read says that sex whilst tied up is the greatest sexual experience you can have," she didn't resist as she trusted him not to hurt her, and after all his track record for sex with her was 110% so far. She lay back and let him tie her up.As he tied her wrist into the other two armlets he told her that this is called Bondage. "I think you'll love this especially with the new toys I've bought for you," as found the adjusters and slowly. She had lain awake many nights, listening to her stepfather fuck her mother. Her bedroom was next to theirs and she could hear her mother’s loud moaning and very vocal orgasms though the wall. Many nights the young teen laid there wishing it had been her he was fucking instead of her mother. Then one day he was home early when Jillian got home from school. She went to her room to take off her school clothes.Being a somewhat large girl even at fifteen her breasts were quite large. As Jillian.
