We had known for a while now that my wife's sister's marriage was in trouble. So when Mattie told me that she'd just gotten off the phone with her sister Ellen, who had told her that it was over, I honestly wasn't surprised. "Rob? I know we've talked about it, but I just wanted to make sure before I mention it to her, she's going to need some time away while all this is going on, so you're sure it's ok with you if she comes here to stay with us for a while?"
I really liked Mattie's family of course, loved them dearly in fact. And though it had been a while since I'd seen either one of Mattie's sisters, and actually had missed seeing them, it certainly wasn't that. They were welcome to come for a visit any time, that wasn't the problem. The ONLY problem as I saw it was, Mattie and I had a very wonderful sex-life that allowed us the freedom to enjoy it openly together whenever and wherever we felt like it. Having guests obviously curtailed some of those wilder moments, but it was usually a short temporary thing. Now, with the knowledge that her sister would actually be coming here to live with us for a time, it meant giving up a few of those spontaneous naughty adventures we so enjoyed experiencing together.
But, family was family, and first things came first.
"You know that it is," I assured my wife sincerely. Neither one of us speaking the same shared thoughts, we didn't have to, knowing one another so perfectly the way we did. Mattie even addressed my thoughts though unspoken.
"And don't worry honey, we'll find naughty ways to have fun, even while she's here!"
I smiled at that, there was a certain edge to that which appealed to me of course. An element of additional excitement and danger associated with "getting caught" especially with it being her sister that tickled that decadent spot inside my head. She grinned seeing me smile.
"You thinking what I'm thinking?" she asked.
I unzipped my pants removing my hard stiff prick, showing her that I had been.

They might indeed have been sisters, and certainly had some similarities designating them as such, but that's about as close as it came in some ways. Mattie had wonderfully large breasts with incredibly nice sized nipples that she loved having me play with. I had seen Ellen's breasts once, seen her nude actually when she had visited us before and sat with us out in our hot tub. Nudity in our home, especially while doing that was of no moment, neither was it for Mattie's sisters and family whenever they'd come for a visit. So it wasn't without natural curiosity and observation that I'd taken note of a few points, among them being the difference in how Mattie and her sister's looked when being naked together.
Ellen had nice sized boobs as well, not quite as large as my wife's were perhaps, but nicely shaped with a similarly colored nipple. And unlike my wife who kept her pussy totally shaved, Ellen preferred the more natural though neatly trimmed look, which was quite a contrast in comparison, but made it interesting for me upon that discovery. Ellen was also a few inches taller than my wife, nearly my own height at five-nine though their natural hair color, as well as their hazel eyes was virtually the same. Mattie had chosen to include adding some red highlights to her own hair color, giving her a devilish little pixie look that really accentuated her eyes and her smile whenever she gave me one of those patented looks of hers, telling me in a moment she was in the mood!
As expected and planned for of course, Ellen arrived a few days later and immediately settled in. It was good to see her and talk to her again, even under the most difficult of circumstances. That first night after her arrival, we had again slipped outside to sit in the hot-tub, relax and have a few drinks along with some easy conversation which Mattie and I had agreed needed to steer clear of the obvious for the time being. There would be plenty of time for that later. So it was that we sat talking about some scenic places we'd enjoy seeing again, sharing with her Sister who seemed quite relieved and relaxed by our purposely chosen topic of conversation.
All this while Mattie sat next to me in the tub wonderfully fondling my cock.
With the jets going and the water bubbling the way it was, there was no way of course that you could see anything or know what was really going on there beneath the water, though Mattie's hand being in such close proximity towards my lap might have been a bit of a clue as to what was going on, though Ellen certainly never appeared to be aware of it, let alone say anything. And I was certainly enjoying the erotic play, until it was realized that we were all in need of fresh drinks, so taking a moment more to allow my stiff prick to soften considerably, only then did I unashamedly slip out of the tub and head back inside the house to make us all another drink.
Funny thing about water, sound travels very well across it, so as I stood in the kitchen making everyone another drink, I could clearly hear their conversation from outside through the open window as I stood there.
"Where you doing what I think you were doing?" Ellen asked her sister.
I could hear by her tone of voice it wasn't said in shock or embarrassed surprise either, having more of a light curious connotation to it that sister's might often share in open confidence with one another, and no doubt just as they had often done while growing up together by the sound of it.
I even heard Mattie giggle as she answered. "Not sneaky enough where we?" she stated still laughing. "I hope we didn't make you feel uncomfortable then," she soon added a bit more seriously.
"Oh not at all, actually...I found it very arousing," she said honestly. "Been a long time since I've even felt aroused," she now added with her own serious connotation being included.
"Would you prefer that I didn't?" Mattie asked her sister.
"Mattie, it's your house. I know how much you and Rob love one another, and if anything I've been a little jealous of your relationship and closeness, but I actually find it wonderfully refreshing that the two of you have and share such intimacy together, so what I'm trying to say here is, don't stop doing that, or sharing that together just because I'm here. I'd rather find some motel to stay in rather than cause the two of you any problems!"
"Don't be silly," Mattie told her sister. "You're not staying anywhere but here, and that's for long as you'd like, and you know that. But it IS nice to know that you don't mind the two of us being affectionate, we always have been, and I know that Rob enjoys that every bit as much as I do. And besides, he really is a bit of an exhibionist you know, just in case you haven't noticed."
Ellen laughed heartily at that one. "Oh yeah, couldn't help but notice that. He wasn't exactly hard when he climbed out of the tub to get our drinks, but he wasn't nearly as small as he was when he first got in either, so that pretty much confirmed for me that the two of you had been fooling around beneath the water a little."
"We'll try and tame things down a little," Mattie told her.
"Don't you dare!" Ellen said almost immediately. "I'm serious Mattie, just because I'm here staying with you, which I truly appreciate, I don't want it to disrupt your home-life OR your sex-life either for that matter. Just try and pretend like I'm not even here."
Mattie really did laugh then. "Not sure about that," she told her sister, "if we were to do that, you never know WHAT, or WHEN you'd walk into something!"
Ellen didn't comment further, just nodding her head though smiling, which is when I decided it was time to make an appearance again before they both started wondering what had happened to me. There was only one small problem with that, having stood there listening to them I was hard once again, not having a full-on massive erection perhaps, but it wasn't just sitting there dangling either. Grabbing our drinks, and hoping that the ever increasing darkness as the sun had finally began to set would help cover the obvious, I quickly made my way outside, pausing to place our drinks on the bar which was attached to the tub's gazebo, effectively hiding my situation for the moment anyway, and perhaps give me just enough time to relax somewhat, at least reaching the same proportionate size I had been when getting out to go into the house.
"What took you so long?" Mattie asked not helping the situation.
"Oh, I uh...had to pee too," I thought quickly.
"Ah huh," she grinned winking at me. "Didn't look like that's what you'd been doing when you came back outside," she said.
