It had been more than a decade since my big sister and I had sex. Our situations weren’t the same now. We didn’t live under the same roof. Our parents were long gone by now. We were also both married.
I wondered regularly if my sister thought about our sex as much as I did. Each night almost, I would fall asleep remembering the curves of my sister’s body. I closed my eyes remembering her silhouette riding my cock as I struggled to not cum inside her.
I was on an international flight one day and started typing an email to her. I had no idea if I had the balls to actually send it.
I asked a few basic questions after telling her what I remembered of our sexual history – did she think about it also? Does she miss our time together? Given the opportunity, would she want to revisit the experience? If we were in the same space again, what would she want me to do to her most?
There were also a lot of specifics that I added to my email. I mentioned specific times we’d fucked and in certain places where we should have been more cautious. I also think the thrill of doing something so forbidden added to the excitement. My sister also had a fucking amazing body – big round tits, dark pink nipples, hips made for grabbing while fucking her doggie-style and a pussy that needed no artificial lubrication.
After a few complimentary cocktails and a lack of sleep, I hit SEND on my email and drifted into a sleep reserved for airplanes.
I landed at my destination and spent my day running from the airport to meetings to dinner and my hotel. I was toast by the end of the night. I forced myself to take a shower as I’d not had one in better than 36 hours.
As I settled into bed, I popped open my laptop to catch up on work. I’d forgotten about sending the email for just that bit of time. Now, I had an unopened email from my sister staring right at me.
I opened the email with some hesitation. She might be pissed? Maybe she didn’t want to recall the nights of taboo sex we’d had? What started as innocent playing had escalated as we both had hormones surging. Soon our innocent play was giving me an erection. As I would go shirtless around the house, my sister would lick her fingers and tap my nipples if she could. As I got more excited, I started to let her win.
One night, when she reached for my nipple, I said, “If you want to wet it, why don’t you just lick it?” To my surprise, she did. Within minutes my sister went from licking my nipple to sucking it. I could feel my cock stirring.
After she left, I jerked myself off and came excessively.
The next night, we were playing cards with a few candles for light. It was Summer and hot as hell so we used as little electricity as possible. Still, I always cranked my air conditioning to the highest level. As we played, I could see my sister’s nipples hardening. She had little tolerance for cold, so the AC likely was causing her nipples to harden.
I pointed at one and made sure she saw that I was licking my fingers.
“At least I’m wearing a shirt, unlike you,” she said.
“So… you don’t have to in here. No one is looking except for me, and I think you owe me a look and a lick,” I said boldly.
“I’d feel weird,” she said.
“Maybe you could just suck my nipples for a while again?” I proposed. “Then if you feel OK, we can try something else.”
I took off my shirt, and my sister leaned in and licked my nipple again. After some licking, both of my nipples were rock hard and so was my cock. I wasn’t bold enough to let my erection show so I did what I could to mask it. All the while my sister continued to suck my nipples and tease them with her tongue.
I started stroking her back and hair while she sucked. My hands began drifting down to her sides and feeling the roundness of her tits. I was shaking with anxiety and excitement. As my hands began getting bolder, I would drift to the front of her chest and make contact with her hard nipples. I would brush them so as not to freak her out. She was wearing a tank top that wasn’t too low in the front, or I might have tried diving into her cleavage.
Now she was getting into this more and my hands were firmly on her tits. I was kneading her breasts through her shirt and keeping my index fingers at her nipples. I began slipping my fingers into the sides of her straps. Soon I was at her waist and slipping one hand underneath the tight fabric. Eventually I came to the bottom curve of her tit. As I pushed and pulled at the material, eventually her tits were fully in my hand. My fingers were teasing her hard nipple.
“Can I lick yours?” I asked.
“Okay, but go slow,” she replied.
Now I watched as my sister pulled her tank top over her head. The candlelight did nothing to diminish her beauty nor did it hide her amazing tits.
My sister leaned back, and I moved forward. I took her tits in each hand and did as she’d been doing to me. I began by licking her nipple and then moving to the other. As each became wet, they popped up like pencil erasers. Then I began sucking on my sister’s tits. I watched as she leaned her head back.
This went on for a few minutes, and then she started moving towards me. As she put her hands on my shoulders, she began kissing my mouth hungrily. I could feel her wet and hard nipples against my chest and again, my cock was at full capacity at this point. Once she lay me back on my bed, she had to notice my erection pointing straight up at the ceiling.
My sister wrapped her legs around my left leg and continued kissing me and drifting down to my nipples and kissing them again. She was riding my leg s if she was fucking it. At the time, I had no experience and no idea what to call what was happening.
As she sat up wearing only a pair of shorts, I watched as her magnificent tits swayed in the candlelight. I could feel the pre-cum oozing out of my cock now. This was better than leafing through an old issue of Playboy magazine.
My sister was trying to balance herself as she was grinding into my upper thigh. As she fumbled for a spot to lean, she inadvertently bumped her forearm or wrist onto my cock. I nearly came the instant she made contact. I wondered if the pre-cum had leaked through my underwear and left a streak on her arm.
“We should stop,” she gasped.
“Only if you want to,” I replied.
She stood straight up and searched the bed for her tank top. As she was lifting blankets and shaking them out, my cock stood proudly up in the air. There was no way for me to hide it now. There was no point either.
As this was happening, I was watching intently as my sister’s tits were shaking as she searched for her tank top on the bed. Once she found it and was pulling it back over her head, the show was unfortunately over.
“I’m going to go,” she said.
“Before you go, can you kiss me like you were before, just one more time?” I asked.
“OK.”
She didn’t sit on the bed this time. She leaned down and started kissing my passionately. As she did, I was able to see those beautiful tits coming towards me. I couldn’t resist and took them in my hands and massaged them while we kissed.
My sister disappeared from my room after that. I don’t think I slept until close to 4 AM. The memories of her amazing tits flooded my mind and did nothing to calm the orgasm I had after she left.
