What to do now? M (35) W (24) MiL (46) Problem isn’t how to get things started, but how to stop.

2 years ago my MiL told us just before the wedding that she disapproves, “because I’m too old for W”. After our wedding she never visited, even for holidays. I wasn’t welcome at her house. 3 Weeks ago W was in a car accident, both of her legs broken. I called MiL and she flew in that night. We sat together in W’s hospital room for 2 days. When my wife was wheeled into surgery, M broke down; it was uncomfortable but I held her for a couple of hours. She just cried the whole time. A few hours after W came out of surgery MiL looked right at me and told me she’d misjudged me.

Forward 10 days, W comes home but can’t get out of bed without help, can’t put any weight on her legs. The only way she could move around is in her wheelchair. W’s first morning back M and I were with her when she woke up. After 30 minutes or so , I left M with W so I could start breakfast. M had said she’d take care of W before I brought breakfast to her. Id only been in the kitchen 10 minutes when M calls “Hurry, come help in the bathroom”.

I ran to the bathroom, and M is Laying in the tub fingering herself. “Are you isane? W will have a stroke”. M said “It’s OK. I gave her her pain pills, she won’t wake up for at Least 4 hours. And I need your help to reach some places”. Then she spread her lips and pinched her clit. I quit thinking with big head. “Youu can help right here”. The whole scene is stuck in my brain.

I picked her up and took her to my room. We went right to it for 90 minutes. She knows positions I never heard of or imagined. And can literally suck the chrome off trailer hitch.

Next morning, W gets her meds, I’m fucking M again not ten minutes after W fell asleep. It pops in my head that we haven’t used a rubber. “Are you on birth control?” “No. Haven’t used it since (FIL) died 5 years ago”. “We have to stop. You could get pregnant.”

Then the bomb dropped. “It’s OK, this whole thing is Ws idea. She is thinking I can move in.” W had talked about ENM. “Think about the 3somes” Which would mean M/D incest. The thought of THAT freaked me out a little and made me soooo horny. Watching them together would be amazingly hot. But is M telling the truth?

It’s been almost a week now. Nothing changed except rubbers I started buying. I’ll eventually have to ask W, but what if M isn’t telling truth? That would tear up everyone’s life. How do I ask W if this is true? I’m not going to lose W, but at the same time if she wants to bring her mother into our relationship I’m completely behind it.

Ideas please.
