Okay, let's set the scenario here. Say you're with a girl, she's about a solid 6, not too good but then also not too bad. Not fat, just not pretty. She has a good friend, who is a solid 9/10. Absolutely nearly flawless. They know each other through playing tennis. Both girls I am at least 90% sure are both heterosexual. If you're dating the girl who is a 6/10, after a while, you both will become more comfortable with each other and in that time, you can ask each other questions to get to know each other. Some of these questions may include performing sexual activities on someone of the same gender. Most girls would actually feel more comfortable having a threeway with two girls rather than two guys. So if your girl is open to the concept of the threeway, you can eventually slip in the idea that you want to have a threeway with her and her hot friend. If you end up having a threeway with them, their combined score adds up to a 7/10, which is good for you bro, well done lad. Allow me to summarize this; - You date a girl who's averageish who has a hot af friend. - You talk to her and get her to be open about a threeway. - You slip in the fact her hot friend might be interested. - Girls always talk, they eventually talk about it. - Both girls are interested in it because it could be a new experience and fun. - You invite them over for some drinks. - You have a good time, maybe play some drinking games. - It gets dark, everyones guard is down. - The drinking games get touchy and sexual. - Everyones keen. - You have a threeway (or pentasex, depending on how many girls your girl invites around) - You get bragging rights to the lads.
