Having fun in your best girlfriend's marital bed? Ok or no go?

I was visiting my girlfriend and her husband and slept on their sofa. Every night anew I hear the two of them pleasuring themselves and that doesn't leave me cold. I couldn't help but touch myself and indulge myself too... when they wanted to go shopping together, I thought I'd take the opportunity to take a closer look at the bed of pleasure... Thinking about what the two of them must have been up to here, I lustfully get it to dirtytalk ?#dirtytalk #satisfaction #marital bed
