Couple in MK, experienced swingers. 
We are only interested in meeting with couples. No single men, please. 

We have children so it's a bit complicated, we can't go out very often, no dinner parties, just chitchat etc. When we meet we have sex, full swap, moresomes etc. 

Also, just to clarify this straight away, we have a very particular taste, we're not interested in meeting overweight or obese people at all, nor anyone (significantly) older than ourselves. It's just our thing, please don't be offended.
