My wife's cousin and boyfriend were visiting us from Australia for a few weeks and staying in our loving room. Over the few weeks a few interesting things happened.

It started with the cousin walking around topless more and more which aftera night of drinking led to all four of us often being naked in the flat. The pair of them were very vocal when it came to them having sex and most nights my wife and I would listen to them whilst having sex ourselves.

One morning the visitors went out for a day and I did all the washing. Amongst their clothes I came across the cousins underwear covered in cum stains from the night before. I was intrigued and couldn't help myself by holding them up to my face and smelling the both of them. It became a bit too much for me and started masturbating in my kitchen. My wife walked in and after some embarrassment she encouraged me to continue, sitting and watching me cum into her cousins panties. I washed them and returned them to her cousin with the the rest of the clothes. My wife to this day still teases me about her cousins panties.

On the very last night of them staying with us we all got very drunk again which led to truth or dare. Nothing too extreme even though we were all naked anyway, but my wife and the cousin did make out and play with each others breasts. The night ended with me and my wife sleeping on the sofa. I was woken during the night by the cousin and her boyfriend trying to be discreet having sex. I started grinding against my wife waking her, she responded and we also started having sex a few metres away from the other couple. They became a lot less discreet when they knew we were also fucking. Woke the next morning, took turns in the shower and they got ready to leave.

We haven't seen them since, but we are planning to go visit them and their other boyfriend soon now they have room for us to stay.
