With my best friend, we have a discussion thread where we only talk about porn.
we send each other naked girl photos and other videos.

I I had the idea to organized a pussy photo contest with him, the idea being to put a heart on the one who loves it and proceed by elimination.

so I prepared a selection of 20 close-ups for him, all very nice pics that I found on Reddit... and without telling him... I slipped in some close-ups of my girlfriend's pussy.. he doesn't know it... but he put my girlfriend's pussy in 3rd place, it's a good score I think..

now when we come to his place for a drink with his girlfriend, he won't know it, but he will have seen my girlfriend's pussy
