Chapter 16: Mark of Submission [R-18]

"Father-in-law" I said sarcastically referring to Seraph's father as I watched him tremble with anger, his eyes had lost all doubt and uncertainty, they were now empty, staring into nothingness.

"Call my sister, today, I will mark your daughter as mine" I said proudly just before he left the room. 

My hands began to work with more fervor, roaming her body with a mixture of possession and devotion. Her moans filled the room, her body arched under my touch, and each caress I gave her brought her closer to the brink of ecstasy.

I stripped her clothes off with a mixture of care and urgency, each falling garment revealing more of her soft, trembling skin. I paused for a moment to admire her nakedness, her beauty taking my breath away. Her eyes looked at me with a mixture of desire and submission, completely surrendered to my desires.

"You are mine, Seraph," I whispered, my voice a low, possessive whisper.

"Yes, Zarok, yours alone..." her reply was a barely audible whisper, but charged with an intensity that made my heart pound harder.

I leaned into her, my lips found her neck and began to kiss her aggressively, nibbling and licking her skin, feeling her shudder under my touch, unable to reciprocate my dominance over her. My hands caressed her breasts, playing with her hardened nipples like two pieces of metal under my fingers.

"Oh, God! Aaah!" cried Seraph as her body arched in pleasure.

"P-Please, Zarok... I can't... I need more..." she moaned, her voice a desperate plea.

I smiled against his skin, enjoying his desperation. I slid a hand down, finding the wetness between her legs. I stroked her clit harshly, watching as her body arched again and her moans that wouldn't stop, grew louder.

"Is this what you want, Seraph?" I whispered in her ear, increasing the pressure of my caresses.

"Yes...please.... more..." her response was a choked moan.

I brought her to the edge again and again, enjoying every moment, watching her need grow to the point of desperation. Finally, when she could take no more, I brought her to climax, feeling her body tense and then relax in a wave of pleasure.

But I didn't stop there. I made sure that every next moment was filled with intensity and desire. My hands and lips roamed every inch of her skin, bringing her to the edge repeatedly. Each time she approached climax, I paused, relishing her desperation and need.

"Please, Zarok... I can't... I need to feel you inside me..." she begged, her eyes filled with tears and desire.

I smiled, knowing I had reached the point of no return. I kissed her deeply, my hands exploring her body once more before positioning myself between her legs. I slowly spread her small legs, rubbing my cock with her sweet juices teasing her.

"P-please... please-r" she begged with the last of her strength.

I took advantage of her blur to penetrate her hard.

"OOOOOOOOOHHHHH!" cried Seraph as she orgasmed steadily as I ravaged her no longer virgin pussy.

Her moans grew louder, her body arched under me, and each thrust brought her to climax. Her nails dug into my back, and her sighs and moans filled the room, creating a symphony of pleasure.

"You are mine, Seraph," I murmured, my voice a low whisper as I increased the pace of my thrusts.

"Yes, Zarok... only yours..." her response was a choked cry, her body tensing once more as she climaxed.

I brought her to orgasm again and again, enjoying every moment, feeling her body surrender completely to me. Finally, when I could take no more, I cum a second time, feeling her body shudder and relax beneath me.

"Come in" I shouted to my sister hiding behind the door.

I saw her beautiful face clearly red, I knew she had been there for some time.

"Got it?" I asked Rina.

"Y-yes" she replied before pulling out a strange potion and her rune pen.

"Start" I ordered my sister.

"W-what w-what a-aah is it?" asked Seraph with serious difficulty.

"A gift" I replied with an extremely sadistic smile.

"My sister and I have created a tattoo of sorts. Last week's potion, I lied to you, is not permanent, but this is," I said as my sister crafted the tattoo in the area of her uterus, in her lower belly.

"From now on, it will be your mark of submission, the demonstration in your own flesh of your devotion to me," I added.

The tattoo is formed by a heart in the centre with undulating patterns extending outwards, symbolising the expansion of desire and creating a sense of movement and attraction. In the background, it incorporates a design that hints at a stylised womb in direct reference to the concept of a receptacle. In between, there are small wings, and shading to give depth and realism, making the design appear more dynamic and appealing. 

A few minutes passed, as my sister finished the beautiful crimson red tattoo like my eyes, I took the opportunity to tease Seraph's body.

"AAAAAAAHHH!!!" cried Seraph in pleasure, enough to make her cum again. 

"Now your brother," said Rina. 

I showed her my forearm as a sign of where I wanted it. Slowly my sister marked the small tattoo, it was a fine elegant S for Seraphine. A strange sensation ran through my body. 

Just as she finished, a crimson light appeared from the two tattoos outwards just before disappearing as if it had never been there.

I took the opportunity to enter her again, with full harshness, without any care or tolerance of her body.

"You stay, and you are forbidden to touch yourself or come. Just sit still," I ordered my sister, seeing that she was trying to slip away. 

I had long known of my sister's strange fetishes, it was she who followed me into town, when I chased Seraph around town. I could tell by her juices from earlier that day and by certain looks she gave me as I thought she didn't notice.

For hours, I had sex with Seraph, pounded her breasts, drank her milk, spit on her, slapped, spanked, spanked, choked, everything you can imagine. Even when she passed out I didn't stop, I continued until I was satisfied, from the beginning Seraph's condition was not important.

My sister's eyes were red, she was panting even to the point that she was struggling to stand, her thighs were rubbing continuously. She held on all night, her face reflected a need no less than Seraph, but it was not yet time to play with my sister.

"You can go" I commanded before watching her leave.

Exhaustion fell over me and I lay down next to Seraph. I was genuinely happy, the future was full of possibilities, and with Seraph by my side, I was ready to face it all.
