Take a long hard (!) look at this photo. What does it do for you? I'm good friends with these girls, so that makes it special. More importantly, I know they are in love. Easy so far? It’s a bit more complicated than that – they are a throuple - new word for me too!  They enjoy each other as a threesome, and as pairs - four combinations.  Lucky dogs, eh? Why I especially like this picture is the expression of love and sexual attraction encapsulated by the gentle hand on each other’s bottom. Oh to make it a quadrouple!
