Caught My Girlfriend Off Guard While She Was Applying Lotion

This slut obviously likes it creamy. I don't mean her pussy, though, but her body. Because before getting fucked, she rubs her entire slender body with body lotion. Her boyfriend seems to like that; he's into kinky stuff and obviously likes trying new things. What could be hotter than really using his slim girlfriend with tiny breasts while she's getting lotioned?
