Louise started to rub herself off as she watched the heads up display. Brad fucked Carla even harder and had her bouncing like crazy with her breasts ...verywhere, as Louise got near a climax Brad stopped fucking and stayed Louise's hand. He then without warning started to hump Louise as she sat on the couch being fucked like her life depended on it. After her earth shattering orgasm that had them all screaming out, Brad stood Louise up and took her position as Carla and Louise started to give. I couldn’t help but undress her in my mind.I tried to concentrate on using my phone but my right hand found its way in my shorts. I couldn’t stop imagining her although a part of me wanted to stop. Maybe that’s what made the experience more intense. I got hold of my dick which was already erect from the entire screenplay my brain’s been witnessing.As I was under the sheets, my dick was lying flat on my belly. Instead of gripping it, I used my finger to rub the base of the penis. I decided not. My heels clicked on the wooden floors, and I knew he could hear every step. My breathing quickened as I reached towards the door, twitsting the knob and silently swinging the door open. He was stood at the window, looking out. His jeans hung low on his hips, the black fleece he was wearing clinging to his lean muscles. He turned to me, his pitch black wavy hair hanging at his shoulder, pushed back as though he'd been running his hands through it. A small grin was hidden behind the corner of his. "Ok Kelly here is lesson number one." I stood up and pulled her up onto her knees, making her lay back at an angle. I grabbed my cock, jerking myself slowly with one hand while grabbing her large mouth watering tits with my other. "The first lesson Kelly is this; sisters with big tits like yours; should be fucked by their brother." I slapped my cock between her tits and placed my hands on her shoulders. "Now push your tits together around my cock." She did what I said and just as I.
