We still shared a room, but with me being 14 and Sarah being 17, mom and dad were doing an addition on the house so Sarah could have her own room. I w...s just starting puberty at 14, and she was 17, so we talked about boys, kissing and sex almost every night before going to sleep.One night, after our talk left me feeling a little funny down south, I wanted to see how far I could take my sleeping sister. After she had fallen asleep, I turned the heat up a little in the room and then started. She replied naughtily ” I had an important thing to see that’s why Didn’t come out of the mirror” “what imp thing?” I asked. “Something I don’t have” I felt shy. “What is it?” She ran away.

All I heard was the bed squeaking and my mother's moans of pleasure."Oh uh oh uh, yesssss darling, harder, deeper, I'm almost there, Ohhhhhhhhh yesssssss, I love you darling I love you soooooo much.

And the nipples looked like they were ready for a child to suckle on. Long and dark, pointing up slightly. Before I could tell what was happening she.
