They come in many varieties. It is basically a sexually oriented party game for adults.
There are some basic ground rules:
1. No one may touch anyone else without prior request on the part of the party being touched.
2. All women come dressed in a blouse, skirt, panty hose, bra and panties. Shoes are left at the door.
3. All men come dressed in a shirt, slacks, socks, undershirt and shorts.
4. I start all off with some wine, cheese and a little get to know each other chat.
5. I always lost, but loved spin the bottle type games as a kid. So I always us a spin the bottle type item. This builds a little excitement and relaxes all a little.
Often the basic Jack and Jill party starts and grows to something more later. Often, as a group is formed using a basic Jack and Jill basic, as the group stays together longer more advanced play is done.
The basic Jack and Jill party is everyone sits down in a big circle. Someone spins the bottle. Whoever it points at takes off the next layer of clothes. For women the usual order is blouse, skirt, pantyhose, bra and panties. For men the usual order is shirt, slacks, socks, undershirt and shorts. Then the bottle is pasted to the next person to spin. Whenever the last item of clothing is removed the individual lays down and masturbates.
As I said, they come in thousands of varieties. Some basic varieties are listed below.
For anything more advance, birth control by women is required.
For more advanced items sometimes the undressed people redress and rejoin the spin, sometimes they just watch for the rest of the game. This is up to whoever is hosting the party, but it should be made clear up front what is going to happen.
The lick off.
Here the bottle is spun by the men and point at the women. One man spins the bottle, then it is passed to the next man to spin. If it turns out pointing to a man, the man response. Whenever the women is finally undressed, he undresses. Then he man jacks off on her bottom, getting his cum all over her bottom. Then he licks it all off.
Men are required to us condoms for any penetration act.
Before hand she has made a list of the items she is willing to do if the man fails to get her an organism and what she is willing to do if she does get an organism. The man also makes a list of what he is willing to do. After he has eaten all his cum, she states what happened to her and they match lists. They do whatever is on both lists. Usually, the women jack him off if they do not get an organism and do more if they did get the jack pot. When they are through, they move out of the circle and the spin the bottle continues.
This game is more complicated because often there are not equal number of men and women. Here if there are more men then women the man must pay a penalty. The women in advance have write if they want to be seconds. The women who want seconds get in a circle and the man spins twice. He must cum on one and eat her. Then he eats the second as a penalty. The women flip a coin to see who matches cards with him. If there are more women than men, then the men who up front had said they would do seconds line up. The women spin the bottle twice to get two men. The first man will cum on her and eat her. Then she gives the second a bj. Then the first man and women match cards and do whatever they have agreed to do. It is important to write all this down first on cards so what happens does not depend on who looks like what, but just the joy of the spin chooses all.
The usual choices are a hand job if he does not get her an organism. If he does, then a bj, regular intercourse, anal sex, breast fuck or some combination of the above are usual choices if he does get her some. She must do something for him either way. If have seen women do as little as a hand job for both and as much as everything for either way. The men usual write down every possible choice so when the cards are matched he can always match something. The above is what I call the usual rules.
There is the opposites match up.
Here the men spin and the women undress. Whenever a lady is undressed, the man undresses and they either masturbate each other or the women does him then he does her. The same rules above apply if too many men or women are there. The man must masturbate two women before one does him or the women does two men before one does her.
Here everyone spins. If a man spins and points to a man or a woman spins and points to a woman they re-spin. Whenever someone is undressed, the spinner undresses and they give oral to each other. The man gets it first then the women. This is a good test on can he keep it together. Some women want the woman to get it first to be sure they get some. This is fine. The rules just need to be clear up front.
This is good if you have a group of people that might be bi. Here first each man and women writes down what they are willing to do if it ends up being a different sex match up and what if it is the same sex match up. One can say they do not want any part of bi. He that individual must spin again until he matches against a member of the same sex. Another possibility if one member is unwilling to do bi and a same sex situation arises then he simply does or gets nothing. This is up to the host house rules, but the rules must be clear before the party is set. Typical choices are to masturbate, give oral or receive oral. The group is seated woman next to man. Whenever someone is undressed the spinner matches their card with the undressed persons card and do whatever matches up. Sometime you have a situation of where one person is willing to masturbate a member of the same sex and receive oral, but not give oral. This is ok. If different sexes match up, then they match up their cards and do whatever.
Bi is ok for sure.
This is good if you have a group of people that might be bi and is willing to do something with the same sex if the situation arises. Here first each man and women writes down what they are willing to do if it ends up being a different sex match up and what if it is the same sex match up. If it is a same sex match up, you must be willing to at least touch and masturbate the other person. Typical choices are to masturbate, give oral or receive oral. You must at least list to masturbate the other member in a same sex condition. The group is seated woman next to man. Whenever someone is undressed the spinner matches their card with the undressed persons card and do whatever matches up. Sometime you have a situation of where one person is willing to masturbate a member of the same sex and receive oral, but not give oral. This is ok. If different sexes match up, then they match up their cards and do whatever.
The I want to try bi, but don't want her or him to know what I have done.
Here the men meet in one room and fill out cards. The women meet in another room and fill out cards. They play there own game with just the same sex and see who tries what. After the same sex is over, everybody gets redressed, gets together and plays another game.
The multiple verse one.
This can be played as multiple men against a few women or multiple women against a few men. I will describe the multiple women against a few men, but the rules are the same the other way around.
Here about six to eight women get together with two or three men. The women spin and the men strip. Whenever a man is undressed, he is taken to another room. He must eat all the women and fuck as many as he can. Then the women return and continue to spin until they have tried all the men. Which ever man can do the most by agreement of the women he stays for the rest of the week-end as their sex slave. The rest go home.
There are literally thousands of possibilities, these are just a few.
