Depressed Mother

My father decided my mother (49) was holding him back, so he divorced her. She got a fair payout according to her lawyer: alimony, a house, and adjustments for inflation. I'm the younger of two, both boys. My brother (31) is married and lives a long way from both his parents, but keeps in contact with both. I (28) live closer to my mother than my father; I run my own business. I do date but have no one special as of yet. After the divorce was final in January, my mother became very depressed. I thought up to me to support her till she got over the divorce. So, I visited her almost every day; then I'd a job interstate to do (April). I asked my mother to accompany me to get her out and about. She agreed after I pressured her a little bit until she agreed. I didn't want her alone too much by herself; the job was fairly easy and didn't require more than a couple of hours each day until it was finished. So, I took my mother around to see the sights; we were gone six days in total; the job was finished in four. But my mother had improved so much being away that I extended our stay by two days. With the job finished, we expanded our sightseeing and came across a strip show. Which my mother wanted to see, much to my disbelief. But she insisted, so we watched the show; it wasn't all that great. But my mother enjoyed herself. After dinner that evening, we were back in our room, which we shared. My mother said she could've done better than the strippers, even at her age. I just smiled; she thought I didn't believe her. She got up and went into the bathroom, returning shortly after in her petticoat and started dancing around the room. At first I was shocked, but then I got aroused, and when my mother sat on my lap as part of her routine, she discovered my arousal poking her. She might have been shocked for a moment or two, but she recovered and wanted to see my erection. To please her, I dropped my pants and shorts, and she wanted to then get me off herself. Had me lie naked on my bed, and she finished undressing. At first she just stroked my cock, then started sucking it. Then, without saying anything, she mounted me. I was too shocked to react; that's what I told myself anyway. If we had only fucked the once, that might have been true. Counting our fuck yesterday, it's about 34 times we've fucked since my job interstate in April. She has sold the family home she got as part of the settlement and moved closer to my place. Her new apartment is on the same floor of the apartment building I live in, 3 doors away. We own our apartments; not every time we're together do we fuck, but we do fuck regularly. She is also trying to find me a wife.
