Three days had passed since my sister had sucked me off, Two of those days were the weekend, which meant the parents were around. No action then. I was wondering how my sister was feeling about what she had done. I felt a little guilty, but I hadn't forced her to do anything. Actually, I hadn't even encouraged her to do anything until she had gotten deeply into it.
So what was I to do? I was way too old to blame it on youth. Maybe Jamie could - she would be nineteen in a few months, and I didn't think she was very experienced. I kept thinking how I had taken advantage of her, but it actually was her who did almost all of it. All these thoughts and more were running through my head on Monday morning. Soon I would be talking to her about it. But right now I was feeling horny. I was waking up with a big erection again, and very erotic thoughts going through my head. My dick was on fire.
SHIT! I finally was awake enough to realize I wasn't just dreaming or idly thinking. Jamie was once again in my room awakening me with her hands. And mouth. Her hand was around the base of my dick and her mouth held most of the shaft. She must have been at it for a while because my erection was hot and throbbing.
"Jamie! Geez! What are you... God, that's good!" I managed to say.
She smiled up at me around my erection. Her tongue kept wrapping around my shaft inside her mouth, and she would pull it halfway out with a strong sucking action. My balls were churning and getting ready to explode.
"Jamie, I'm going to shoot!" I warned.
She smiled again and sucked harder. Soon I groaned, "UUUHHHHH", and out shot my cum, strong shots straight into my little sister's throat. I had a fleeting thought of how much cum there was, as it was my first of the day and I hadn't had an orgasm since Saturday. My cock kept spurting into her mouth, and it was more than she expected. She kept swallowing, but some was leaking out between her lips and dripping down her chin. Finally I was done and she pulled her mouth off.
Jamie was still swallowing, and trying to take deep breaths at the same time.
"Damn," she said, "I was wondering how long you were going to cum." She was smiling up at me so I knew she was okay. "How much was that? That was more than the last time."
I explained. "The last time I had cum before. It's been a day or two this time. There's more cum if it's been longer."
I felt like I was explaining the facts of life to her. How innocent was she? I looked down as she leaned in to lick a drop off the tip of my penis.
"Run your thumb up the ridge on the bottom of my dick," I told her. "It will milk the last of the cum out."
I moaned again as she did that, and then licked the drop off me. She did it a couple more times until no more cum was left. She reached over and grabbed a couple tissues, wiping off my dick, still swallowing the remnants of my load in her mouth.
"Do you need some water?" I asked.
She shook her head. "I kind of like it," she said shyly. "But there was a lot!"
"Have you ever done that before?" I couldn't believe she was so good without practice.
"No. Not until you."
"Have you had other experience?" I asked.
"I felt a penis through a guy's pants. His underpants. But not his bare penis." She hesitated, then continued. "I've had... Do you really want to know this?"
"What?" I asked. "About your experience? Yeah, I kinda would. If you don't mind. But that's okay if you do, I was just curious."
She continued. "I've had sex a few times. With two guys. But they just fucked me. I didn't get to play with them or anything."
The way she said 'fucked me' made me think she hadn't enjoyed the experience. She seemed a little upset, so I didn't press her. But I still was curious.
"Any other experience? I asked. "How about guys playing with you?"
"The only guys I let touch my breasts naked were the ones who screwed me. And that's all they did."
"No oral sex?" I asked.
No," she answered. "Me or them."
