It was Thursday afternoon Sophie and I were in the living room talking about our sexual encounter earlier in the day. "That was my first fuck in over a year." Said Sophie.
"That was my first ever fuck and I fucking loved it, I was beginning to think I'd never get laid, but you were the best teacher I could have ever had, thank you sis, I'll never forget today."
"I'll never forget it either Paul, and just remember we must keep this secret, I'm happy to help you in any way I can. But please don't tell Lynn that we fucked, she bullies me too but nobody sees it and I feel she controls me."
"Well Sophie, let's turn things around and let her think she is bullying and controlling us but in reality we can work together and control her."
"Yes, let's do it. I can't wait."
Sophie sat next to me and hugged me tightly. "Thank you so much brother, I've wanted help to sort Lynn out for a long time but didn't know who could help me."
"You're welcome sis, I'd do anything for you."
Sophie was laid on her back with her head in my lap, I was stroking her hair as we chatted. "Can I kiss you Sophie." I asked.
"Yes, of course you can, any time you want to kiss me just do it, in fact just treat me as a girlfriend when we're alone."
Sophie put her arms around my neck and I held her in my arms and we spent about an hour just kissing. "You're getting really good at it now, I'm really turned on." Said Sophie.
"I'm turned on too, and I love the way you kiss me, you're a great teacher."
Sophie went to the kitchen to get a glass of water, I followed her and she stood at the sink looking out of the window, I realised for the first time what a great arse she had as she stood there in her tight jeans, I walked up behind her and put my arms around her waist pressing my cock against that perfect round arse. "Your hair smells lovely." I Said to her.
I kissed the back of her neck and she said "oh Paul, I love that don't stop."
I moved my hands up her body and held her boobs as I kissed her neck, Sophie put her hands around her back and grabbed my hard cock, stroking it up and down through my shorts. I left one hand on her boobs and put the other one on her bulging camel toe sliding my fingers up and down her slit. "Let's go to bed, I want you."
I took Sophie's hand and led her upstairs, I was about to turn to go into my bedroom then I remembered the hidden camera in Sophie's room so I took her into her own room. I started to hurriedly rip my clothes off and Sophie removed her clothes with the same haste, within seconds we were facing each other stark naked, I pulled her to me and kissed her, my hard cock was pressed against her pussy and her boobs pressed against my chest, holding and kissing my sister like this maybe wrong, but it felt so right.
"I want you to fuck me this time Sophie, I want to know what it's like to have a girl ride my cock."
"My pleasure little brother, get on the bed."
I laid back on the bed and Sophie straddled me, my hard cock was laying flat against my body, Sophie positioned her pussy against my cock and slid up and down the underside of it, I looked down and saw the amazing sight of her pussy lips parted either side of my shaft and her juices soaking my cock as she slid back and forth without actually putting my cock inside her. I saw the head of my cock oozing pre cum as she continued her slide. She then leaned forward and placed her hands on my chest, this enabled her clit to rub along my length and I held her swinging tits as she said "I'm going to cum already."
