Tell you the technique of inserting into the uterus (sex knowledge adult novel)

The act of making love is to insert the penis into the vagina, which gives pleasure to both men and women, but perhaps many people don’t know that if the penis is long enough, it can reach the opening of the woman’s uterus, allowing the pleasure of both parties to burst out in an instant. The feeling of hitting the cervix: As the penis keeps thrusting, negative air pressure will form in the vaginal cavity (the principle is the same as that of a vacuum pump). When the glans hits the cervix, the cervix will also suck the glans tightly. If you shake the penis at this time, the woman will tremble as if she was electrocuted, and the heat in the uterus will also give you an incomparable comfort.
The feeling of insertion into the cervix: If your penis is long enough (generally ten centimeters is enough when erect), the top of the penis can be inserted slightly into the cervix. You will feel like a small mouth sucking on the glans. Stay for a few seconds and then quickly pull it out. There will be a "bo" sound like opening a beer bottle. When you insert it again, you need to use some speed and strength. The entire glans can be inserted into the cervix before it is completely closed (not pushed in). The cervix also tightly bites the cervical groove of the glans corona, and the soft flesh wall of the cervix will hold the glans tightly. You will feel that your penis is having sex with the vagina, while the glans is being given oral sex by the tender flesh of the uterus. Your partner will feel that her vagina and cervix are being penetrated by your penis at the same time, and she will feel extremely comfortable. At this time, thrusting back and forth, or shaking and rotating after insertion, or lifting the woman up high and stringing her on your penis like a kebab, can easily make a woman have multiple orgasms and scream.
Every time women feel the glans entering the cervix, they will twitch, and some even cry, truly understanding what it means to be in ecstasy. Those with the most intense reactions will tremble all over, their thighs will shake violently, their love juices will spurt out, and they will have difficulty breathing. Each time it is inserted into the cervix, it can allow women to reach orgasm multiple times without much effort.
Method of insertion into the cervix: The best position should be the man pushing the cart. Let your female partner half sit and half lie on the edge of the bed, with half a quilt placed behind her back to lift her upper body appropriately, so that the cervix can slide down to the vaginal opening as much as possible. In this position, the distance from the cervix to the vaginal opening will be about two centimeters shorter than when lying on your back. If your partner has not practiced ballet, you can put a pillow on each side of her buttocks and ask her to open her legs as far as possible. You use both hands to press her thighs firmly on the pillows on both sides to make her lower body unable to move. This is because the extremely strong pleasure (for some people it is pain) when inserting into the cervix will make women unable to control themselves and move around, thus affecting your interest. Of course, if you have a sturdy armchair at home, it would be even better. You can open your partner's legs and tie them to the back of the chair with two ties. It's best to tie her hands (of course, you have to get her consent and do it gently to avoid hurting her). This way you can free your hands to do whatever you want.
