apart from being from the 80s.. having a guy over is cucking or at least a 3some but not swinging.. based on her tats and clit piercing (which is very nice btw) this is not her first time taking an extra cock.
While this may have been your first time swinging I can bet it wasn't/isn't your last time. You just looked and sounded so good getting serviced/serving two hard cocks.
