My sister and I were not allowed to date until we were 16 and even then un-chaperoned dates where rare. Holding hands was ok sometimes, but kissing wa... immoral. I of course wanted to know all about boys and sex but never allowed to express my curiosity. Anything remotely sexy was taboo. To make everything worse my sister Mindy was a real bitch; always ratting on me for the littlest things and always acting perfect. Both my sister and I were in an advanced summer school program – no idle minds. So, now you're wondering what the situation was that I startedtalking about.

Master was furious with me and made me lick it off of.

The next night she went out again and later I could hear her entering the front door when she came back home. Ana came up the stairs and into the bedroom where I had passed out on the bed while waiting for her.My sexy wife shook me and told me to wake up, because she had a nice surprise for me. I expected to see a stranger in the living room;. Very slowly, he pushed the toy deeper and deeper into my asshole. It felt like it was getting larger as he pushed it further and further in. I felt immense feelings of pain as he pushed it deeper in, but it was the type of pain that kept you wanting more. As he pushed further, there was some resistance, and he was a little rougher in getting it all in.I yelped as he roughly pushed the last bit in and he whispered in my ear, in a firm but seductive tone, “Take it all in, my little slut”.Feeling.
