Pounding his wife while showering with spectator (long version)

We have been showing together, enjoying the wonderful hot water dripping on our bodies and while helping each other with the soap, we got so horny and passionate! We'd been making out and had amazing sex when I saw our roommates in the window. It somehow amused me, so I just waved at them and we continued. Not only do we enjoy it but also the roommate! And even a second roomate joined in. It seemed like it became a show. ;)
