About two months ago my bf and I had a threesome with my best friend. Despite people saying it would ruin things, it turned out great and we all enjoyed it!! We set our boundaries and everything beforehand so we would be prepared. The threesome was basically them sharing me since they didn't do anything between themselves and honestly it felt great to be pleased by two people. Even though I'm straight I love the naughty aspect of doing something with another girl. My friend even said we should do it again sometime!! Right now I already talked with my bf and he's in. The thing is I have to ask her about it and I'm not sure how to bring up the topic. Any suggestions?
