Tried a few times.. One was too kind and I did not want her daughter to attach to me so ended it very soon, another was pretty crazy 21yo with an annoying little daughter, really horrible kid, I imagined how I lock her in a closet when I was at her place. The funny (perverted) part - she'd put her daughter to sleep (little kids sleep pretty deep) and then after some time I'd fuck her on the same bed right next to that sleeping daughter. Nice mother potential I guess...
