Fucking my Aunt

Ruth 52 is my mother's Helen 48 only sibling, Helen is a widow and I'm her only child. I'm Reg 26 (Reginald) single and live with Helen and I work for a local company in the planning section. I've been fucking Helen for five or so years and I still date and yet to find that someone special. It's just sex for our mutual satisfaction, we started one night while both a little drunk and have kept it up since. We have sex at least twice a month sometimes more, Then aunt Ruth came to live with us after her divorce and she was sour-faced as ever. I joked with Helen, no wonder uncle Graham divorced her waking up next to her every morning. Helen told me not to make fun of Ruth and give time to come to terms with the divorce. Luckily we have a self-contained annex with our home and Ruth was staying in the annex. After several months and no improvement in her demeanor, I said to Helen on a rainy Saturday afternoon after fucking her what Ruth needs is a good fucking. Helen replied well you give her a fucking then. Me, not me I said, are you chicken then, Helen asked. No how would I get her into bed I replied. We'll have to both work on her and get her drunk also Helen answered. So we started getting Ruth to join us on our outings. Slow going it was and I didn't think we were making any progress. Then we made some headway, getting Ruth a little drunk and getting her naked in the hot tub with us both. But she fell asleep and we put her bed with us both naked and Helen and I had sex with Ruth passed out beside us. In the morning Ruth awoke first soon followed by Helen and then me. Nothing happen again for about ten days and then we went to the wedding of their cousin Julia and we all stayed in the same motel room together. Ruth got drunk at the reception and on us returning to the motel room I suggested we put Ruth in one bed and we fuck in the other. Helen said no we all sleep together and you fuck first and then me. I don't think she will wake and in the morning I will say we were all drunk and all had sex together. So that's what we did after I had finished fucking Helen. Helen told me to fuck Ruth again and I did. In the morning Helen woke first and shortly after Ruth awoke, while I was still asleep. Helen told Ruth, we had all had a little bit much to drink at the reception and got frisky on returning our room. One thing led to another and we had a threesome together and her Ruth wanted sex and went first then followed by Helen then Ruth again and that was when she (Helen) fell asleep. Ruth claimed not to remember and shocked, but Helen just asked her did she enjoy the fucking as much she seemed too last night. Ruth said she couldn't remember and Helen replied that's what you say. Then the 2 of them went into the bathroom together and Helen got Ruth to join her in the shower. I awoke shortly after and called out to Helen and was told to join her in the shower. On entering the bathroom I saw both Helen and Ruth naked in the shower and stopped. Helen told me to join them and give Ruth another fuck. That was Last October and Ruth is a regular fuck for me now and gone is the sour look on her face.
