M44 F41 couple seeks sexy couple for fun and swaps

We are a laid back couple looking for sexy fun with a similar couple. We consider ourselves to be attractive and easy going with a good sense of humour.
He is 45 slim build and 5ft 9in. She is 42 size 14/16 34DD 5ft 7in sexy and very bi. Both are non smokers.
We are both busy professionals who expect discretion and obviously offer the same.
We are hoping to meet couples for safe sexy fun and swaps, a bi fem is preferred. We enjoy sensual all hands on fun after a flirty build up and we would like to meet more than once. We would also like to explore mfm and fmf with a couple as well as the mfmf scenerio! Same and separate room fun is fine.
We like going to clubs occasionally (this suits us well as we are usually unable to accommodate due to nosey teenagers in the house!) but we can travel or arrange a hotel for more intimate fun.
