Laura was a bit of a hanger on. She always wanted to be included. I guess it was tough for her, as she really had no one her age to hang out with. After my brother died, she really was the odd one out.
As we all got older and passed through puberty, we definitely noticed the differences in each other. Laura loved to flaunt her chest and flash her crotch at her brother and me. I think she just enjoyed the attention, not realizing exactly what she was doing.
I do remember one Saturday night that her parents and my mom were out drinking at a local bar pretty late. In the weeks leading up to this, she had been laying around the house in her nightshirt with no panties on, the bottom of it barely covering her rear end. Her brother John used to swat her on the ass pretty hard and told her to cover up with a blanket. Throughout the night, as we watched Saturday Night Live on the couch, she would slowly pull the blanket down, seeing if she could distract us from the show. It usually worked with me. I'd get one of those rock-hard teen boy boners that refused to go down. She would rock her hips and make her ass jiggle, this was the 80's before twerking was a thing. John would usually break it up by telling her to go to bed. She would walk out of the living room, switching her hips the whole way.
The night that I remember, John had gone out with his friends, leaving Laura and I alone in the house. She had come up with the bright idea to give each other massages with baby oil.
Since her parent's bed was a queen sized, we decided to do it there. She started with me, putting oil on my back and rubbing the muscles there. She did a pretty good job with it, all things considered.
When it was her turn, she laid on her stomach and had taken off her top and undone her bra. She was wearing a pair of what we now would call jogging shorts. I rubbed her back with the oil, enjoying the sight of her glistening skin and the feel of her muscles under my hands.
As I moved my hands along her ribs, she lifted the top of her body up, so that her breasts were no longer trapped. Instantly, my boner popped up. I wasn't sure what to do. She whispered, "Go ahead." So I did what any normal 14 year old boy would do. I cupped her breasts, feeling her nipples pucker in my palms. The oil helped as I massaged them, rolling her nipples in my hand.
I was straddling her hips from behind, my erection buried into the crack of her shorts through mine. She started wiggling her hips against me, moaning as I pinched her nipples.
"You want to?" she asked.
"It'll be OK. Just lay on your back."
So I laid down on my back as she pulled her shorts off. She slipped mine off so hard, she made my boner slap against my stomach. She straddled me. Reaching down between us, she grabbed my erection by the base and slid it inside. She was slippery, warm, wet. I had never been inside of a girl before, so I wasn't sure what to do. I licked and sucked her nipples. I could feelher contracting around my cock as I did this, so I figured I was doing the right thing. When I tried to move my hips, she said "No, stop." so I did.
After a few minutes, I felt a couple of flicking spasms from her as she threw her head back and groaned. It happened about 3 times before she slid off of me and ran from the room. I wasn't sure what I had done wrong. A few minutes later, I heard her in the shower. I picked up her clothes and took them to her room. When she got out of the shower, she went to her room and closed the door. She and I never spoke about it. In fact, this is the first time I've told anyone about it.
She and I had an adversarial relationship after that. I guess she thought I seduced her? I never really found out. All I do know is that she was my first real sexual experience. I didn't orgasm with her, though. It wasn't until I was married that I was able to do that with a woman, and at great effort.
