"I want to go back to being a woman while my child is going to school..." I'm being treated by a single mother who has a lot of sexual desire

The neighbor in the room where I live is a single divorced mother with children. As they somehow become friends and close together, they start to listen to the worries and complaints they find themselves as single mothers. Furthermore, she is a mother and a woman, so she looks after me. Of course, I also had ulterior motives. So, until my child gets home from school, my mother returns to the woman and embraces me. Not a lover. She just throws her sexual desire with nowhere to go on me. I accept that. That's just the relationship.
