We might meet only once a month with all the members, but some members would meet in smaller groups more often if they cared too. We were young and ol...d, male and female, beautiful and average, gay and straight, and we all loved masturbating.It had all began slowly, of course. I was the instigator. I loved jerking off. Much more than fucking, which I had experienced several times. But I had always returned to jacking it for my real pleasure. I wasn't married and had found that rubbing one off in. . shoot it up me" fill your mother with your dirty cum." God I was cuming, my spunk ejecting from the end of my penis, wave after wave deep into her hole coating the inner walls of her cunt. Mother body convulse as a huge orgasm exploded through her. We lay together my softening cock still inside her cum filled hole, the only sound that of our breathing. I was first to speak, the realisation of what had just happened now totally clear in my mind "God what have we done... oh god I'm sorry. "I guess I'm not the only one who likes the idea," I said as I took my fingers out of her dripping wet pussy and brought them up to both our mouths to suck on. "Mmm, you taste so good." I then gave her the look of 'I'm going to fuck your brains out'. Arlene smiled as she knew what was coming. she rolled onto her back and spread her legs. "Oh, baby, yes, fuck me hard." We kissed passionately as I positioned myself on top. I reached down and aimed my rock hard cock at my step-mum's hot love. She didnt exactly dress like an average teenage girl. She didnt use makeup and she dressed more like a young boy in jerseys, t-shirts and jeans than in some dressy fashionable way. He didnt encourage it either way, he just let her be herself. He felt it was the right thing to do. For the first time in his life, looking at the curvature of her bodice, and the movements from her heightened arousal, he was seeing his little girl as a young woman. He couldnt help not to, because a little girl.
