I Love My Girlfriend

My girlfriend was showering just now and after she had finished, I heard a peculiar, continuous slapping sound coming from the bathroom for several seconds. When she got out, I asked her what the hell all that slapping was and she got all embarrassed and said "Damn, I was hoping you had your earphones in. I was slapping my boobs. 😅" I was taken aback by that. 😐 So after a bit of a pause, I inquired why, lol. She said she was rubbing lotion on herself and that her breasts were looking "really perky" so she decided to play with them for a bit. I'm usually the weird one in this relationship but every now and then, she'll do something weird like that. 😆 Or maybe this is something more common than I think and I just don't understand it because my boobs aren't that big... 😑
