As some on here know, nothing turns me on more than the smells, sounds and visuals of a guy and girl - two sexy, fit people, fucking each other's brains out with athletic vigour and them getting off putting on a performance for me as I enjoy the sight of of their glistening sweaty bodies in sextreme sex. Now, I'm happy to just be passive and watch them go at it, But, I'm wondering, given that they are likely to be keen to explore the bondaries of sex, if they would make me earn my keep, by attending to their needs during their coupling. I wonder how many would want me to guide his cock into her and be there in case it fell out so they could be lost in the physical act completely. I wonder also, how many of the guys would really tease me by coming over to where I was watching and actually fuck her while he grinds their fuking in my face. They might want me to clean up their mess after or film them or be used as a further set of hands added to their pleasure. Anyone's thoughts? My question is how many couples would leave it at being watched and how many would take it too far?
