I wonder if he is hard now? At the same time he started jerking off again. It sounded wetter this time. His stroking was loud. I felt electricity run ...hrough me and my balls started to throb as my cock hardened. I couldn't take it anymore. I licked my hand and started jerking off with him. I spread my legs wide and worked on my cock not caring if he heard me or not. Fuck him! He was louder than before. It was so fucking hot. I couldn't wait to hear him cum again. He gave me what I wanted fast.. Helen sat before him, shoving a towel under her arse to keep it from the cold floor. She leaned forward and took the cock-knob into her mouth, flicking the sensitive underside gently with her tongue."Oh mum, that feels good. You really are a great cocksucker."Helen, for obvious reasons couldn't reply. At least not with words. She looked her son straight in the eye and started bobbing her head up and down, taking just the top couple of inches every time. Helen loved the feel of the cock head. She was so excited.I stood and took off my pants and underwear and I was already pretty hard just from talking to her and feeling her up as I told her what I had planned. I took the tupperware container cover off and dipped the head of my cock in it and she dropped to her knees and without breaking eye contact with me closed her mouth around my head and began to suck, lick and throat her moms cum off my cock. She stopped, reached up and took the container from me, dipped my cock head into it. I too was eager. Just then she told me that she was talking about anal.Guys trust me anal porn is my fave. She spread her ass cheeks wide open and asked me to lick it. As I was licking she used to push my head deeper into her never ending ass crack. It was pinkish brown in colour.While fucking her I cummed thrice inside her butthole. She wanted more of it but my sister was calling her name.From that day onwards both of us never wore of undergarments ..And my sister didn’t notice an any of.
