Mum swore that it would be our secret. I wondered just how many more secrets we would share before my plan was over. The next week I bought her some f...owers and the week after a small box of her favourite chocolates. She thanked me each time, but as the presents became a normal part of each week the fuss she made began to die down. Eventually, after about six gifts in as many weeks had been accepted, I bought the big one. Again, the timing had to be just right. My chance came one afternoon when. Here is PART 2:I was on cloud 9 the next day at work and couldn’t stop thinking about the day before and the masturbation experience I had with my wife’s sister. I kept running the images through my mind – her smile, her hand on my knee, her smooth white stomach below her belly button, her hand under her white flowery panties and the glimpses of her dark pubic hair, her own glances at me rubbing my erection. I kept wondering how much she had really seen – I was pretty sure that all she could. . ) and got into the habit of biting my tongue when I was taken for their grandfather...I knew about milestones; the time they began to hold their heads up, the moment they were able to sit up, or roll; first solid food, first teeth ...

I asked"Oh yes!" she nodded with a grin."Great! now let's see what it's like with both!" I said picking up the big pink rubber cock again.Michelle looked at me in surprise again and replied "Both! What do you mean, both?" I mean both!" I replied grinning, then I placed the big rubber cock up against her tight little pink ring, and while my cock was still hard in her wet leaking pussy, I began to push the head of the dildo into her ass."Oh god Steve, no!".
