She turned her head slightly, the side of her eye made contact with mine and she turned back. Did I just see her blush? This morning was turning out t... be way more exciting than could ever have anticipated. Suddenly she shuffled back, her ass softly pressing onto my hard cock. As the train moved along, we swayed together, my bulge still pressed in the middle of her butt cheeks. She started to move her ass a little, grinding me while pretending to use her phone. I put my phone down and looked. Cynthia kicked off her shoes and stepped in, the water was hot enough to make her jump, straight back into Mother. She felt arms coming round her and landing on her labia, she didn’t try to escape, but opened her legs a little more and then leaned her hands on the two walls, bracing herself.Mother’s fingers found her clitoris and began circling. Cynthia had always done a straight up and down movement when masturbating so this was a new sensation, and very pleasant. It didn’t take long, she had. Slowly..Slowly..She lowered her hands rubbing along the way from my chest..Down to my belly and now she was very low..Too low..I twitched a little and pretended to be fast asleep already.Moaning a little in pain from the fever.What happened next changed everything…I could feel my mom’s warm hands enter into my tracksuit bottoms.Through my boxers and touch my hard 8inch cock…I jolted a little and she grasped it. I opened my eyes and she looked into mine. I saw my mother’s eyes and stared at it. I just looked at her, "My husband had a vasectomy some years ago and even though I'm older there might still be a chance I could get pregnant". "I haven't used a condom since I started dating your sister and I'm not starting now. I am going to fuck you bare and cum inside of you" I replied and with that I plunged my dick all the way in to her pussy. She let out a loud gasp and arched her back with the sudden violation of my member. But her gasps soon turned to moans as I started fucking her.
