I always thought pussy smelled horrible

see whenever i bent my 1st gf over and took her from behind it smelled like a skunk shat and died. it was only later that, about 15 minutes after a rather hasty wipe i smelled a similar smell. it was then i realized with my gf it was the aroma of unwiped ass i was smelling, not vagina.

The only people that have serious trouble wiping their ass are those who would be considered obese.

Your girlfriend had serious trouble wiping her ass.

Therefore, we can assume that your girlfriend was obese.
