I smiled and blushed, and we were silent for a few moments as we stared into each others’ eyes. I asked him what was on his mind, and he told me tha...t the way I was looking at him was sexy, and that it made him want to kiss me. I said, ‘Then kiss me.’ He did. He wasn’t shy about it either. His tongue frantically searched out mine while his hands began exploring my body, making me tingle with excitement and causing my panties to get increasingly damp. As I kissed him back, my own hands traveled. As I headed for the bathroom, Caroline stretched and got up. As I came out, she came in and gave me a quick kiss on the way. We were out of the door and on our way at a fairly rapid pace by five to six.Caroline said, "You're excited about the R&D center this morning, aren't you?" I sure am, Babe. This is a big deal. I'm getting a wide open budget to make one of my ideas into a reality. This is really going to be fun. I bragged that I would have something done today, and in my mind, I can do it. I don’t know what about that experience got me so hot but it did. After getting into my room and realizing it was my little brothers cum on the back of my thighs I did what no sister should, I grabbed some with my fingers and put them to my mouth. Damn, my brother’s cum tastes good.That night I put on a pair of black panties and rubbed myself off until I couldn’t help but cum. In my ecstasy, I pushed my little black panties up inside me to catch all of my juice. After cum soaking them I took. That's how it started, and we added things like blindfolds and Mary just wasn't the same woman in bed. It got to where she was calling me names of her coworkers that hit on her at work. I guess I should tell you a little about my Mary. She's 26 stands 5 foot 3 and weights 122, she has very lite blond hair with the baby blue eyes that drives me nuts. Her B cup tits are firm with dark red nipples which I love she hates cause she says they are to sensitive. I will say if she's in the right mood.
