The first night at sea

Privacy was usually a hard thing to come by on a vessel like this, but Vel’s quarters offered plenty of it. And, as she was his sworn shield, Dina had been given the steward’s cabin right next to it with an adjoining door. All of which was good, as Vel was currently being treated to the sight of his muscular and busty sister undressing for him. As she slid down her undergarments and straightened back up, Vel appreciated the way her muscles moved under her skin. She truly was a marvel.

Dina smiled at him in the low light, naked save for a few delicate chains. She still wasn’t wearing the large one, at Vel’s request. He knew she wasn’t thrilled about it, but she made do with her smaller more easily hidden chains for now, knowing that the time when she could show her self-imposed penance openly was coming soon.

“Hells, Sis, you’re too fucking sexy. I am going to fuck you till you can’t walk straight.”

Dina’s smile widened.

“From anyone else I’d think that was an empty promise, but I know from experience that it isn’t.”

He got up from where he was sitting on his bed and pulled her into an embrace, their lips locking in a tender kiss. Vel’s hands roamed over his sister’s sculpted body, his fingers admiring every curve and contour. Her fingers got busy undoing his clothing, which inevitably meant they had to break their kiss. He carefully took off her chains, wanting her completely bare for what came next.

Without any warning Vel flung Dina onto the bed of his cabin, which really was more of a large cot. She let out a surprised yelp that quickly turned into a giggle as she got comfortable on her back.

“Oh my. My little brother wants me so bad he’s turning into a ruffian.”

Dina stretched out on the bed provocatively, ever so gently shaking her chest as she did so.

“You sure make for an irresistible sight, Sis. Your body is beyond words. Knowing I am the only man who will ever touch you drives me wild.”

A shiver passed through her at those words, and her smile grew. Vel really was going wild, his manhood stood hard and proud. Not wanting to wait any longer, he climbed on top of his sexy sister.

Dina was wet and ready, and moaned up a storm as Vel slid himself inside her tightness. Luckily there were plenty of noises to cover for them, including the ever-present creaking of the ship’s timbers. His sister’s first climax arrived as soon as he bottomed out, and Vel showed his fingers into her mouth to stifle her now even louder moans, just in case. It was a turn-on for them both too, and Dina’s tongue got to work swirling around and in-between his digits as soon as she recovered enough, her eyes locked onto his. There was such devotion and submission in them, such worship. His dick twitched, he didn’t think the thrill of his once haughty and bitchy sister being so completely subservient to him would ever lessen.

Vel hadn’t started thrusting yet, having stopped when he bottomed out and Dina came.

“Fuck! I love you so fucking much, Vel.”

She sounded out of breath already, which Vel thought was hot.

“I love you too, Dina. And I love these.”

Vel leaned a bit lower over his sister and grabbed her perfect tits, sinking his fingers into that sweet flesh. Dina trembled and moaned at his touch; her eyes again filled with devotion. Her legs spread wide for him, Dina wanted him as deep and close as possible. He leaned closer yet, sliding his hands down to the outer sides of his sister’s tits and pushing them together. Slowly, almost reverently, he gave each nipple a flick and lick with his tongue. Dina trembled and moaned. She only grew louder as he sucked one of her nipples into his mouth and lightly nipped at it with his teeth. There wasn’t any milk to be gotten here yet, but it was only a question of time. Vel couldn’t wait to taste it.

“Please, Vel, more, please. I need it.”

Vel loved it when his wives begged, but it was especially hot when it was Dina, for obvious reasons.

Moving his grip back to the tops of her breasts, Vel slowly pulled his hips back. His sister’s insides seemed **** to let him go, that incredible musculature gripping him almost like a hand. A very warm hand wearing a moist velvet glove, though. Dina, of course, was moaning again. She only grew louder as he pushed back in, her eyes closing and head tilting backwards.

“OOOOH FUUUUUCK!”

Vel kept going, slowly but powerfully fucking his sister. With each thrust he plunged a little deeper, his weight pressing her knees ever deeper into the mattress as she kept contorting her powerful yet flexible body to allow him even greater access, wanting him to plunder her very deepest parts.

Vel couldn’t help a few moans of his own escaping as he kept fucking his older sister, both the physical sensation of tight wetness and her incredible reaction just too much to stay silent. She looked at him as if enraptured, like she really was looking at her god in the flesh.

“Shiiiit, you feel so fucking good, Sis.”

Vel felt her spasm around him at the praise, her second climax approaching. He entered her mind, seeing the joy she took in pleasing him, and pushed on her pleasure to hurry it along. She screamed as she shook under him.

As Vel had hoped her second orgasm had loosened her up a bit, and now he could finally really pound her. The angle at which he had to fuck her now was a bit strange, with her being bent pretty much double, but he managed it, plunging in and out of her at speed while she fought to not scream. He’d had to move his grip from her tits to her ankles, allowing her breasts to jiggle wildly as Vel hammered into her again and again.

“OH FUCK FUCK FUCK FUUUUUUUCK!”

Her third climax was not long in coming, and Vel, exhausted by the demanding position he was in, let go too, flooding his pregnant sister’s insides.

Afterwards the two cuddled close, the limbs entangling and their sweaty bodies pretty much glued to each other. After a few minutes though, Vel disentangled himself from his sister’s embrace and got up to relieve himself. After he had filled the chamber pot, he turned back to the cot, and the view that awaited him briefly took his breath away.

Dina lay basking in her afterglow. Her naked, sweaty, and thoroughly fucked body on full display, his seed slowly trickling out of her. Something about the moaning, panting, and writhing had strained Dina’s abdominal muscles; her abs looked more defined than ever. The expression on her face was beatific, Vel wasn’t sure he’d ever seen anyone looking quite that satisfied.

He just stood there for a little while, taking in the glorious sight as the boat gently rocked under his feet, before rejoining, the siblings once again embracing. The cot was a lot smaller than the beds they were accustomed to, so they had to snuggle close indeed. Neither minded. Dina sighed contentedly against his chest, but he felt like something was bothering her

“What’s wrong, my love?”

Dina sighed again.

"I'm so happy, but also feel so bad. I love that I get to have you all to myself on this trip, but I feel guilty too, because my fellow wives all have to be apart from you. I shouldn't be happy when they're suffering, should I?"

Vel couldn’t help but smile. It was rather adorable to see her being so considerate of the others, and to hear that she enjoyed having him for her alone. He gave her nose a little kiss.

“It’s nice to see you thinking about the others, but this isn’t any fault of yours. I had to go on this mission, you, as my sworn shield, had to come with me. Enjoy it while it lasts and try your best to not feel guilty about it, as that won’t help anyone.”

She returned his smile, at least somewhat reassured.

"I suppose I only have you to myself until you start fucking Fionne."

Her smile grew and she got a wicked gleam in her eyes.

"Gods, I can't wait for you to dominate her and put her in her place. To show her where she belongs, like you did with me. It's going to be so hot."

She shivered in his arms at the thought. That was hot indeed. He gave her another kiss, then both fell silent, and it didn’t take long for them both to fall asleep.
