Estudiando y poniéndose cachondo

Once again I found it really difficult to concentrate when I was studying the other evening - the boring book couldn't hold my attention because I was feeling so horny! I slipped my big tits out of my tiny t-shirt and started to massage them, and then I slid my short denim mini skirt up. I wasn't wearing any panties so I was able to just finger my wet pussy with no interference.
