Some Girls Just Have It.
I have many experiences of females who were genuinely into sex. They usually have pleasure and many get well lubricated. Some (two of maybe 50+) have even squirted. Many have orgasms, and some of those are intense. Of all these females, just two have had this auto-gyration thing, and one of those was my sister. I should explain exactly what I am talking about.
It's fairly simple actually. If you've ever seen someone's pet start humping the air, it's like that. Basically, a rub on their pussy is required, but it doesn't take much, and they don't even need to be in the mood. In fact, a random person can just quickly grab them by the pussy and give it a rub, and it will happen. A pap-smear at the gynaecologists can do it.
They're seemingly blessed (or maybe cursed) with this body feature, and I even believe it's not related to their sex drives. One of these females, who was like this is my sister. If her pussy was rubbed, her hips gyrated, and it wasn't her in control. If you started rubbing, she'd hump away automatically, and if you didn't stop, she wouldn't either. The size of the gyrations varied and sometimes, it was easier or harder to get it going.
I would deliberately grab her on the pussy from behind and immediately start rubbing it. Often it would be no more than around twenty seconds, sometimes with her resistance at first. On the right day, it can be as fast as five seconds. It was a funny thing, a little like someone who is extremely ticklish, but different.
I really am guilty of taking advantage of this with my sister. I would chase her around the house until I cornered or caught her, and I would immediately either shove my hand down the front of her clothing on the outside of it, or I would find a way to touch her bare pussy by getting my hand inside her clothing. Either way I would start rubbing straight away, until her hips began thrusting her pussy against my hand. At that point, I would be trying to replace my hand with my cock. I would pin her down and get her naked from the waist down. The whole time, she can't stop humping me back.
In the early days, there was no penetration, just rubbing with my hand or cock and sometimes my mouth. My goal was to cum, so that involved sliding my shaft along her slit until I would ejaculate either all over her pussy lips, or on her pubic bone.
The fact that she's gyrating the whole time, often meant that I came faster than I wanted to, especially once penetration started. I would frequently want to go for second helpings as then I could last much longer and enjoy it more. It wouldn't be that unusual for me to cum several times in an afternoon after school with my sister. How nobody ever noticed the smell of sex at times was actually unbelievable. How we managed to keep it a secret was incredible luck at times. She didn't always have orgasms either, and often they were quite mild orgasms.
At times, she had rules, such as I could get close, but not touch her pussy. I was allowed to masturbate and cum on her pussy while she was naked or partially so. I could lick and suck her nipples, but kissing was off-limits.
Fucking her hard, deep, and fast, was awesome when it happened, especially if it ended in a creampie. Getting her wet with her own juices rather than my mouth was hot. But ultimately it was a combination of her great looks, and the fact that we both knew how wrong or taboo it was that we snuck around to have fun basically. That's why we did it, because it was a heap of exciting fun. Plus we got off on it being naughty. There were some fairly risky stuff happening at times. I have to this day, had more sex with my biological sister than with any other person in my life. That is actually saying something because I have had a lot of sex in my lifetime. I have even had partners for as long as things with my sister lasted, but I still fucked my sister more.
My sister never allowed me in her ass and wouldn't suck my cock. So I've definitely had more of that with others and practically zero with my sister. I got to fuck her tits and I did manage to achieve a few facials with my sister, but she was never pleased about it.
I love to learn how other siblings have had sexual encounters and I will try to reply to questions. Thanks for reading.
