Up the steps

I sat next to my girlfriend Amber awkwardly watching the movie. We were visiting her family for the holidays and her stepmom would just refuse to hang out with my Amber for some reason. As we watched we were forced to listen to listen to her alone...moaning, whimpering, and more. As we watched every line followed by a faint moan or groan, every scene tied off with a "fuck me" it was getting to much for us. We knew she had been lonely since her husband, my girlfriend's dad, passed a few years ago but this was ridiculous. "Maybe we should let her know we can hear her" Amber prompted. I loved her, her blonde hair, her modest nature, her care and affection for everyone, loved it all. I leaned over and kissed her cheek. "How will we go abo..u.." my sentence cut short by a surprising feeling, I was growing erect very fast, and before I could even hide it I suddenly felt close to a sensation I had known since I was a teen. I groaned as I came in my pants, I was stunned as it happened and so was amber clearly. As my cock twitch and shot time seemed to slow for me, before I had even finished my groan my world faded away and I found myself feeling another orgasm, this time it was like it was throughout my whole body but everything felt wrong. As time started to speed up I felt my hands wrapped around something...fleshy, as I looked down I heard a many scream from downstairs.
