Last night, I posted what is most likely the end of things with my MIL. There's always a chance that she'll change her mind at some point and text me, but there's no way for me to know that right now. Several days before that, I told MIL that I wanted to tell SIL what's going on. MIL was fine with it, I told that I trust SIL to keep a secret. Everyone is over 18 and again this is 100% real. Hence why I should play the lottery.

A little backstory: SIL and I a very close. We've always been able to confide in each other, knowing that the other won't say anything unless we know it's ok. I trust her completely, she trusts me as well. Also, she is a beautiful girl, and very sexually adventurous.

I sent her a text on Sunday, telling her that I wanted to share something with her. I said, “Last week, I stopped over to visit your mother, and ended up giving her an orgasm by rubbing her legs. I did it again a few nights during the week. She asked for it to a regular thing, as your father can’t do anything due to his health. (Wife) knows, I wanted you to know”. She said, “Wow!! I noticed she was in a better mood, but I never in a million years would have guessed that was why. I mean I’m glad she’s happy again, I know how lonely she is. If it’s going to be anyone, it should be someone she knows and someone who cares about her”.

SIL asked, "How did it happen?". I explained how it went, she said, "As happy as she was today, you must have made her cum really hard, lol". I said, "It was the first time we'd done anything, so I don't have anything to compare it to, but it seemed pretty strong".

This is where it takes a hard left turn: SIL said, "She said, "Lol, I'm sure it was. To be honest, I could use a good orgasm right now. (BIL) has been working long hours, so I haven't gotten off in a close to 2 months. I'm half tempted to ask you for a leg rub, lol". I got super nervous at that statement, lol. I said, "I'd be half tempted to accept if you asked, lol". She said, "Really? You'd do that if I asked you to?". I said, "Yeah, why wouldn't I? You're an attractive girl, and you must need it if you're thinking of asking me, lol".

She was quiet for a bit, and said, "It would have to be OUR secret, like you couldn't tell (wife, who I did end up telling, and she was fine with it) or my mother. I can't even believe I'm suggesting this". I said, "I wouldn't tell anyone, but this is up to you. It's your decision".

She said, "I'll be alone on Wednesday evening, (BIL) and the kids will be out at a soccer game. Do you want to stop by?". I said, "I can, are you sure about this?". She said, "Yes, we trust each other and we can keep this between us".

I said, "Ok, if you're sure. If you change your mind just say something". She said, "I will, but I doubt I do. Hearing about you making Mom cum got me really excited, lol. Any suggestions on what I should wear?". I said, "That romper you have and white pantyhose". She said, "Deal. Text me if you're bored, otherwise I'll see you Wednesday". I sent SIL another text that said, “and no panties”. She said, “Lol!! Of course not, I didn’t plan on it”.

On Monday morning, I again asked if she was ok with this. She said everything was fine, she said, "Yep, I'm really curious as to how you made Mom so happy, lol". I said, "Lol, why are you so curious?". She said, "I don't know, I just am. It's obvious that you're doing something right, as happy and relaxed as she was yesterday. I'm feeling tense, and I know an orgasm would help me loosen up. I could do it myself, but it's not the same as having someone do it for you". Our conversation ended with her saying, "It'll be fine, trust me. Just know that I'm a moaner, lol".

I was driving home on Monday, SIL sent me a text. It said, “I’m alone tonight, husband and kids are the grandparents house. You want to stop by”.

I drove over, she was indeed alone. Answers the door in a blue romper and white pantyhose. She smiled and said, “is this what you were talking about”. I said, “yes, it is. You look great”. She said, “Aww, thanks. That’s nice of you, I care see why Mom is happy”.

We went in and sat on the couch and talked for a bit. It was hard to not let my hands wander. Eventually she said, “Well, I didn’t get dressed up like this just to talk to you. Want to go upstairs?”

We went up to her room, I asked her to lie down on the bed on her stomach. She did, I rubbed her shoulders for a bit. I asked, “do you like that”, she said, “oh yeah, that’s nice”. I worked my way down to her butt, which is really nice by the way. I moved down to her feet, spread her legs a little and started on her legs. I could hear her breathing a little heavy, and moving her hips. I said, “is this working?”, she said, “you know it is. I thought this would be good, didn’t think it would feel like this”. I said, “it’s the pantyhose, I can slide over your legs a little easier”. She said, “that’s probably it, but please don’t stop”.

I’m rubbing the inside of her thighs, and it’s getting hot in that room. Her legs are opening a little wider, and I’m moving up between them. I brushed her pussy and I could hear her moan. I put my thumbs on each side of her pussy and moved them in a circular motion. When I started that, she started getting loud. She said, “I don’t know what the fuck you’re doing, but please keep doing it. You’re getting me there”.

I said, “you like that”, she said, “my lips are soaked, they were sticking together but they’re sliding against each other. Dear fucking god!!”

I kept doing that until she started moving her hips faster then she started moaning really loud. I could feel that area tighten up, I knew she was cumming. It lasted for probably 20 seconds, then she laid down on the bed moaning as she was breathing.

I stopped, and rubbed her legs. I asked her, “how was that”. She said, “dear god, where did you learn that? That was so good, damn”.

I said, “turn over and I’ll show you another trick”. She said, “absolutely”.

She turned over and I got between her legs. I moved her shorts to the side and started rubbing her pussy. Her pantyhose were soaked, I knew they would be. I started rubbing her clit and using the pantyhose for friction. The more I did that, the wider her legs spread. She started moaning and breathing heavy, and I could tell when she was cumming. Once she stopped, I stopped rubbing her clit in case she gets sensitive. She said, “I get it now, wow. I can see why Mom is so happy, that was amazing. Meet me downstairs”.

I went downstairs, she came down a few minutes later. I said, “you still look really good”. She said, “I should, I haven’t felt that good in a long time. Thank you”.

I said, “you don’t have to thank me. You said you needed that, I wanted to help you”. We sat on the couch again, she kept shifting around. I said, “you alright”, she said, “these hose are sticking to me, that’s your fault, too”. I just smiled, she was right.

She stood up and said, “you want these, I’ll take them off for you”. I said, “sure, I already have a pair of your mother’s. Same color, too”. She took the romper off, had a shirt on under it. She took her pantyhose off and handed them to me, I could see everything. She said, “it’s fine, I’m fine with being like this in front of you after what we did together”.

I got up to leave, she walked me to the door. We hugged for a moment, she said, “maybe again soon”. I said, “really? Thought this was just a one time thing”. She said, “So did I, but after what you did one time isn’t enough”. I said, “yeah, let me know when you’re in the mood again”. She said, “works for me”. We hugged again, a little tighter this time, and I left.

That's part 1, there will be a part 2. We've been texting a lot over the last few days, and have plans to meet on Saturday. Hope you enjoyed this one.
