Friends Old Mom Doesn't Know What Is Going On

My friend asked me if I was interested in taking care of his mom he told me if I do he will pay me 1800 a week and have free living I told him I'll give it a try not knowing what I was getting into the hardest part was getting her in the bathtub after the 3rd time I said fuck it and got in with her which it made it easier but she would grab my dick and wouldn't let go and it felt good I would soap her up and play with her titties and rub her clit when I had to dry her off and get her dressed she would sit on the bed I would rub my dick on her pussy and stick it in and pump it really hard she's so tight
