My wife moved a woman in with us for a summer. And I mean she moved right into our bed. From time to time, I fuck my wife's ass. Had been for several years at that point. Girlfriend was watching us. I was working a job nearby; they were teachers on summer break. So, sex was happening around the clock with them. Girlfriend's curiosity got her to get my wife to play with her ass. It was a full-on anal training between women. I don't know the extent of it, but often on Saturday mornings, wife was doing her shopping allowing me and girlfriend to be alone. She asked me to fuck her ass. I did, stretched her out really good and eventually started stroking it. I know she was a bit uncomfortable, and I offered to pull out. But she stayed the course, and I eventually put my load inside. She normally wanted seconds but this time she kind of went to sleep for several hours.
