"So, was that your first threesome?" I asked my two nieces.
"Yes!" they responded in unison, looking at me like it was the stupidest question they'd ever been asked.
"And your first lesbian experience?"
"Yes," Britney said.
"Of course," Bev replied at the same time.
"Would you do it again?" I asked them.
They didn't answer so quickly this time. They looked at each other and giggled.
"Do you mean a threesome or lesbian sex?" Britney finally inquired.
"Either one."
They hesitated some more before finally nodding shyly.
"I thought so. I didn't hear any complaints," I said.
My twin, eighteen year old nieces sat on their beds in the tiny cabin of a cruise ship. They were in their sexiest bikinis, the ones they wore earlier in the day when I hosted them in my cabin while my wife shopped on shore. As had been our deal from the second day of the cruise, each alcoholic drink I got them cost them one piece of clothing. In this case, two drinks each were purchased with the top, and then the bottom, of their bikinis.
Being the beautiful young women that they are, I had found it a little too tempting and we ended up in a very enjoyable threesome.
"Uncle Steve, we were talking right before you came in," Bev said. She was always the less inhibited of the twins, so I knew something serious was up. "We...uh...both really, really liked it when I made Britney cum."
"I'm glad," I said, suspecting there was more to come.
Bev paused, then said, "We'd like to, um, maybe try it with another woman."
"Great. I doubt that two girls as beautiful as you would have trouble finding a volunteer on a ship with probably a thousand other women on it," I said.
"Well, we have a specific woman in mind," Britney chimed in.
My eyes widened. "Oh, yeah? Who?"
Neither one seemed to want to answer. Finally, Bev said, "Aunt Jan."
I nearly fell off my chair. Their Aunt Jan was my wife. "What!? Are you kidding?"
Both girls looked frightened, as if they had just broken something expensive in a store. I wasn't mad—I was shocked.
"We just thought...," Britney tired to say.
"You want to...to...have sex with Jan?"
I thought they were going to break out in tears, so I quickly went into repentant mode. "I'm sorry. I'm not mad. It's just that...God, I didn't expect you to say that."
Bev spoke for the twins: "She's so pretty and nice and we feel kind of guilty that she can't enjoy what we're doing."
"I think I've created two monsters," I said. "No wonder the drinking age on here is twenty one."
The girls giggled.
"How do you propose we get her to agree to this?" I asked seriously.
The twins shrugged. "We thought maybe you could work that out."
"ME? You want ME to set up a threesome between my wife and my twin nieces?"
"We'll let you watch," Britney said.
All three of us burst into laughter that was heard halfway down the hallway. When I could talk again, I said, "Damn right, I'd want to watch. But to tell you the truth, I'm afraid this may have to happen without me. I seriously doubt that Jan will have anything to do with it if I'm around. I'm thinking you're going to have to 'sneak up' on her, if you know what I mean."
Both girls nodded.
"Can you try to arrange it somehow?" Bev asked.
I thought for a second. "Maybe. This will take some thinking. And if we pull this off you will owe me big time. BIG time."
"We'll worry about that later," Britney said. "Please, Uncle Steve. We really want this."
She batted her luscious eyelids, knowing I'd cave in to that. Her sister started to pull her bikini top away from her beautiful breast.
"OK. OK. I'll talk to you later tonight or tomorrow morning."

"Are you having fun?" I asked Jan as we lay naked in bed, my hand caressing her breast.
"Absolutely. How about you?" she asked, rolling more onto her back so I had better access to her chest.
"It's been great." I felt her hand touch my cock and it twitched in response. "Have you made any new friends?"
"Oh, not many."
I rolled her nipple between my fingers. "I thought maybe you would have found a female friend or two, there's so many around."
"I should be asking you that question," she said, clutching my cock a little harder the longer my erection got.
"There are some beautiful women on board."
The foreplay continued without any discussion for a minute or two. I sucked on the breast closest to me, causing the nipple to rise dramatically.
"Have you ever thought about being with a woman?" I asked while taking a break from her tit.
"What? Are you kidding?" Her head snapped around to me quickly.
"No. I'm serious. Have you ever wanted to have sex with another woman?"
Her hesitation gave me hope. "Well, I've thought about it, but I wouldn't say I've ever WANTED to."
"I just thought this would be a great opportunity for you to try it. No strings attached. You'd never see her again," I reasoned.
She frowned. "Just like a man. You do realize we need more than just a quick fuck to make us happy, don't you?"
I moved my hand to her pussy. She spread her legs. Jan was already wet and I used the dampness to rub her clit. She stiffened and moaned.
"Haven't you ever wanted a beautiful woman to touch you...kiss you...lick you all over?"
I rubbed her clit harder. Her hips rose from the bed.
"Just imagine a woman's face buried in your pussy, sucking on your clit and sticking her tongue deep inside you."
I pushed two fingers as far into her hole as I could.
"Oh, God. Yes. Fuck me, Steve."
I rolled on top of her. "Imagine a babe on top of you, her big tits hanging down waiting for you to take them into your mouth."
I saw her lick her lips, her eyes closed. I positioned my cock at the entrance to her hole and drove it in almost violently.
"Ahhhhh. Fuck! Yesssss!"
The bed slammed against the wall as I fucked Jan fast and hard. I grabbed her thighs and pulled her up. Then I put my hands under her ass and repeatedly thrust my cock into her. As I suspected, she came in a matter of seconds. But it seemed different. The orgasm lasted longer and seemed more intense. I wondered what she was thinking about.

"OK, girls. I've got her thinking about it," I told Bev and Britney when we were alone after breakfast the next day.
"She said it was OK?" Bev asked excitedly.
"Well, we didn't talk about you guys specifically. Just the topic in general. She's at least thought about sex with a woman before," I explained.
The girls looked a little confused. "So how do we get her to do it with us?" Britney asked.
"Listen—I can't do everything for you. What I suggest is you find a time to be alone with her in our cabin and then work on her. Make her not want to refuse it," I said.
"You mean seduce her?" Bev said.
"You gotta do what you gotta do."
The smile came back to Britney's face. "This might be fun."
I told them I'd find an excuse to be gone all afternoon. It was up to them to do the rest. We separated with smiles on our faces and excitement about what lie ahead.
From what I could tell, Jan was happy to be able to spend time with the girls. They were her sister's kids and she'd been close to them their entire lives. She was jealous of the eighteen year olds' long, dark hair and incredible thin bodies. Jan wouldn't admit it, but she could live with the incredible thin bodies a little better if the girls also didn't have perfect breasts and asses.
Not that Jan was a hag. For a thirty eight year old woman, she had a good figure herself. Her breasts were still firm and full and she'd kept her weight at or below what a woman her age should be. She had short blonde hair that looked amazingly sexy when it was messed up a bit...like in bed.
When the time came, I kissed Jan and told her I'd be back on board the ship long before dinner. She slapped me on the butt and said, "Stay out of trouble."
"Same to you," I replied as I walked out the door.
Across the hall in the twins' cabin, they were changing into their most revealing tank tops and shortest, tightest shorts. Fifteen minutes later they were knocking on Jan's cabin door. Soon after that they were on their way to the theater for a workshop on what to shop for at the next island.
When it was over and they were leaving the show, Jan asked, "So what now? Where do you want to go?"
