I must confess I normally imaginethe ones on here with the strongest views in compromising positions.
FB... well I have seen her in boots and basque with a riding crop. Although I can't see her too clearly as I am face down on the bed and tied up.
Kentswingers777 (the male half) ummm this sort of fluctuates between a smart suit pushing me up against a wall and fucking someone hard with me watching. To watching as I fuck his wife... (imagination is a beautiful thing)
Wenchy... well, with her that is easy, she is waffling about how she doesn't really dowomen. As I start to undress her and kiss each part of her body that I reveal.
RPM... I imagine him bent over in front of me, tied up with his own tool belt and rimming his ass.

I could go on..... but I shall leave you people to add your imaginings...
