"Mateo can go fuck himself," Gia said, stuffing a buttered roll between her lips, "I'm serious. I'm going to focus on me for the rest of the cruise. I'm going to eat well, tan and relax well, and I'm going to fuck well too."
"Gia," Jessie said, watching her little sister eat another roll, "I'm sure Mateo is sorry for--"
"No, seriously. Fuck him. We're done."
My wife's 18 year old sister was still a teenager after all. She was all high school drama, even though she graduated two months ago, and even though her body was all woman too. She had the kind of perky large naturals that long pro strippers wished for, and the bouncy curvy behind to match. Jessie was only seven years older than her sister, but she looked at Gia aghast at how the teen flaunted her body: wearing skimpy tiny bikinis, tank tops with no bra, thongs that rode up her belly and invited eyes down to her ass. I tried to remind Jessie that she had been the same way at 18, when we met: a tasty little tart whose big tits I dreamed of sucking long before I ever got the courage to ask her out. Except for her blonde hair, Gia was the spitting image of my dark haired wife, although perhaps Gia's ass was fatter, not that I ever tried to look. Gia liked to tease me and call herself jailbait, even though she had already turned 18 almost a year ago. She knew I was a man after all, and men liked to drink in the sight of Gia like a smooth and smoke-scented whiskey glass.
"I'm sure Mateo doesn't want to spend the rest of the cruise by himself..."
"Then he can jump off the railing for all I care. We have two weeks left on this cruise and I'm not spending another second with that sniveling loser."
Mateo was Gia's boyfriend: a scrawny basketball loving kid a year above her in school. When he left for college, she cried and cried into Jessie's arms all night. Surely, they would follow the mould of every high school couple and he would be seduced by skanky college sluts. They would be fighting non stop.
They did fight, though not because Mateo strayed. In fact, the poor boy stayed home from every party, rather to imagine the gorgeous curves of his girlfriend Gia and touch himself. It was Gia who found long distance tricky. Late nights on the phone, she woke the whole house up screaming: "I did not touch any of those boys, Mateo, seriously!" In actuality, she had sucked four dicks at the school dance and already planned to let them take her three holes together.
The cruise had been Gia's belated 18th birthday gift. Something she had begged for. Please, Jessie, take me and Mateo on one of those gorgeous Caribbean cruises. And yeah, your husband can come too, I guess. So Jessie had shelled out the dollars for the four of us to get medium-sized rooms on board. And now, Gia wished Mateo had never come.
"What did he do that was so bad, Gia?"
"He's just a loser! Why is he so lame, seriously?"
"What'd he do?"
"He just... ugh!" Gia was all hormones, swaying breasts, eating endlessly from her plate from the buffet. "He was so rude to me before dinner that I told him not to come. Like, how fucking dare he?"
"What happened?"
Gia grunted. "We did, ugh, fucking jet ski rides on that little island this morning." The boat had been docked at a tiny private island this morning on its way to Jamaica for the main part of the trip. "And he accused me of rubbing up against the instructor."
I had seen Gia and Mateo taking their lessons. Their instructor was a local, a giant muscular Jamaican man with dreadlocks past his shoulders. Gia had been wearing a little bikini stretched tight over her huge tits, which was drawing attention from many of the guests.
"Were you, Gia?" Jessie asked.
"Okay, maybe a little! He was hot. But that doesn't mean Mateo can be rude to me. It's my fucking trip. He's lucky he's even here."
"Gia, sweetie," Jessie said, rubbing her sister's shoulders, "You can't just be mad at him forever. You'll have to make up with him before bedtime since he's in your room."
"No, I fixed that," Gia said, "I told him to stay with you two."
Jessie and I looked at each other frowning.
"Come on!" Gia shouted, "He's got to sleep with you guys. I'm not letting him back into my room. And what do you guys need the privacy for? You already fucked today."
Both Jessie and I looked at each other. After swimming in the ocean, Jessie and I had retreated to our cabin and had some of the most mind blowingly good sex in a while. Jessie rode me, dangling her big titties in my face while I spanked her while inside her. We both came twice. The idea that Gia and Mateo had heard us making love from the other side of the wall made us blush now.
"Relax, you two can be married and screw or whatever," Gia said, sucking down a drink from a straw, "Just take Mateo in."
In the spirit of cheering up her sister, Jessie agreed.
"Speaking of fucking," Gia said, "I talked to that jet ski instructor at the end of our lesson and he said he'll take me dancing tonight around the ship's clubs." She stuffed a final buttered roll in her mouth and stood up. So that's why she was wearing a tight club dress, the neckline completely open for her bra-less tits and a cutout around her midriff and thighs that showed off her skin. Even her hair was done up in a special way, and her make up was particularly considered.
"You're not supposed to go to those clubs if you're under 21," Jessie said.
"So? I'll be with Zidane. He works here and can get us in."
I considered telling Jessie the other important fact about the jet ski instructor: the man must have been three times Gia's age. Muscular and youthful, sure. But much older. But she was already so upset, I couldn't bear it.
"Smell ya later," Gia said, blowing kisses to us and trotting away.
"I swear," Jessie said, fuming.
"Oh please. You don't remember yourself at that age? You were sending love letters to Mr. Pinkowski." Jessie at 18 had had a wildly inappropriate crush on our history teacher.
"Ugh, that's true," she said, "I don't think I told you this, but we made out after graduation."
"What?!"
"Yeah, he invited me over and cooked me dinner while his wife was gone. We didn't too more than that, just drank champagne and went skinny dipping in his hot tub and made out a little... but I didn't tell you then."
I rolled my eyes. Even though this story was ancient and I knew Jessie was committed to me, hell, she had married me, this past story still stung. She could tell, and rubbed my shoulders lovingly.
"I guess you're right. Girls at 18... they're just uncontrollable."
After dinner, while Gia was presumably grinding and flirting with the Jamaican hottie, Jessie and I retreated to our room. We opened the cabin door to find, perhaps not unexpectedly, Mateo. He was laying on the bed on his phone. It was the same unmade still damp bed that Jessie and I had fucked in. To Jessie's horror, her moist and slightly torn bra and panties were out in the open on the bed where she had left them, right next to teenaged Mateo's face. She quickly grabbed it and stuffed it in a suitcase.
"Sup guys," Mateo said, "Thanks for letting me crash here."
Jessie made a look of sympathy. "I'm sorry about your trouble with Gia."
"Yeah, Gia gets like this," he said, "Just gotta apologize and wait for her to get over it." At least Mateo seemed used to these patterns.
Jessie reached for her waist to begin undressing, but then she remembered Mateo. Sheepishly, she grabbed her pajamas and retreated into the bathroom to change.
"Yo man," Mateo said, "I heard you plowing Jessie earlier. Nice going."
"Mateo," I said, "That's hardly appropriate..."
"Relax. We're the same, bruh. Both fucking these sisters. So tell me, how tight is a pussy when she's 25?"
"Mateo, please--"
"Cause I'll tell you, Gia's snatch is fucking tight. And so is her asshole. She loves when I'm fucking her from behind and I got one hand on her titty and the other just sticking a finger right into that asshole."
The image of Gia on her hands and knees being fucked and prodded flashed through my brain. My cock twitched.
"Jessie's pretty tight," I said, giving a little smile. I had to give up a little for this poor kid.
"Fuck yeah. Cause, you know, I think Jessie's tits are bigger than Gia's. What size is she?"
"Bra size? An H cup."
"Fuck, I didn't know they made 'em that big! Gia's only DDD, and I thought that was fucking massive."
"Haha, yeah."
"Cuz, like, with tits that big, I bet you could fuck 'em," he said. He groped the air in front of him as if he were squeezing my wife's breasts. "Like, you could slide your dick between 'em real good."
"You could do that with Gia, though, right?"
"Nah man. I tried. I kept hitting her in the face."
I nodded in agreement, though it didn't quite make sense to me.
Jessie re-emerged from the bathroom, wearing her pajamas. I went in after her and got changed too.
"Mateo, sweetie," Jessie said, "We're going to go to bed now."
"Oh alright. I'll scoot over." He edged to the side of the bed to make room, and kicked off his sneakers to the floor.
Jessie looked at me. Without words, her eyes said everything: the poor kid's girlfriend is out dancing. Let him sleep in the bed with us.
I breathed and turned off the lights. I took the side of the bed, with Jessie in between us.
"Goodnight, boys," Jessie said playfully.
"Night," Mateo said. And immediately, he began snoring loudly.
I woke up a few hours later in the dark. I heard the sounds of whispering: Mateo and my wife, trying not to wake me.
"Mateo! Turn over."
"Nah, Mrs. S, I like to sleep this way."
