MFM threesome with husband

Me and my husband have decided to experiment - we have been together for 7 years and dirty talk about group sex + threesomes come up very often.

We have decided to do this on our holiday in June, meet someone at a bar and go back to the hotel have fun and send them on there way without exchanging numbers etc.
