The other incident occurred the next night on Christmas Eve. My father and step-mother had gone off to bed. Lanie and I sat by the tree, admiring the lights and talking about Christmas and our memories from childhood. It was a sweet conversation, but a short one, as we both headed to bed before it got too late. A quick and unexpected kiss on the lips and a sexy smile sent me on my way. I was just about to fall asleep when I was stirred by some sort of weird sound. I thought I heard a buzzing of some sort and awoke enough to give a careful listen. As I listened intently I detected a soft whimper from next door and realized that my next door neighbor was playing with a vibrator.
My room was pitch dark so my senses were on high alert as I was suddenly wide awake and turned on by the very notion that Lanie was pleasuring herself only a few feet away from where I slept. I knew our beds shared the same wall, so I strained to listen and tried to figure out what she was doing.
The low whine of the vibrator sounded like it was somewhat muffled; like it was tucked tightly between her legs. And her soft moans were obviously being stifled by a pillow, as they sounded muted and plaintive. I was suddenly and completely aroused and my hand went down to gently stroke my cock as I listened intently. I wondered what she was fantasizing about and secretly hoped it was me.
I knew I was going to come, so I timed my release the best I could to be in sync with Lanie’s. Even through the wall I could detect the final crescendo of her arousal and a deep muffled groan and a shake or two of the bed against the wall were all I needed to release myself. I shot a huge load all over the sheets and bedspread as I collapsed into a deep slumber.
I looked at Lanie a little differently on Christmas Day. She was perky and almost a bit preppy that morning. But I knew she’d been masturbating to beat the band only hours earlier. I had a new appreciation for the depth of my young step-sister’s sexuality. And I wanted to find out more.
It was at lunch on Christmas Day that my father informed us that he and Marilyn were going to go visit my Uncle Chester up in the Hudson Valley the next afternoon and that they’d stay up there for the night and return early the following day. Lanie and I were welcome to come if we wanted, but he’d understand if we wanted to stay behind. Lanie and I looked at one another like co-conspirators. We smiled at each other and both knew what the other was thinking.
“Thanks, Dad, but I think I’ll hang. I still haven’t seen Jeff or Phil and I know they’re in town tonight. Tell Uncle Chester I said hello, though. Okay?”
Dad turned his gaze to Lanie.
“Yeah, me too, Frank. I’m going to be heading north to ski in a few days and think I’ll take a pass and lay low. Hope that’s okay.”
“Sure. I’m kinda springing it on you anyway. Well, keep the home fires burning for us. We’ll head out tomorrow afternoon. I’m sure there will be plenty of leftovers, so you’re not likely to starve,” he joked. Lanie caught my gaze and winked. I felt a little shiver run down my spine.
