  ...

  Vdimir, who was in his sleep, did not hear this, of course; he was just lying in the bed while his sister kept poking the head of his penis.

  When suddenly, it became as tall as an Eiffel Tower, just about 4 inches. For the exaggerated words? Just for fun i guess.

  It even hit Seraphina's cheeks when she lowered her head to have a good look at it.

  She could not help but find the smell a little stinky. "Big brother, thing smells so bad," she muttered as he leaned back a little, where her lips are just in close proximity to Vdimir's gns.

  She then began to touch the head of his penis, caressing it like it was a toy. This made Vdimir groan in his sleep, feeling unfortable.

  Hearing his groan, she stopped and looked at his big brother; seeing no anomalies, she tinued her work.

  She ed her finger around the head as she squeezed it sometimes when suddenly the system notification sounded.

  [Your skill 'Iron Rod' was activated]

  Then Seraphina, where her fingers ed around the head, began to throb, and it grew taller, making her awed.

  "Wow, it's so big," she said in awe as it already hit her lips; the hardness made her shiver.

  Seraphina also felt something stickier on her lips as she backed off a little and touched her lips; there was sticky white liquid, which made her a bit fused sihis came out from the small hole of his brother's thing, where the pee that came out.

  But it did not smell like pee; out of curiosity, she could not help but open her cute little mouth.

  As her cute little tongue was stig out, the liquid in her fiips looked like milk, so she wao taste it.

  As she licked the white liquid that got out from Vdimir's hole, her eyes turned wide as she tasted something that she could not expect.

  It tasted rich, creamy, and slightly tangy, but smoother. It's also sweet as her tongue relishes the fvor. It tasted 10 times better than her mother's milk.

  "Wow, I did not know Big Brother could make eveer milk than Mom," she said with excitement as she ied the head of the penis, but there's nothing anymore.

  "If I am right, the milk came out from this hole," she said, filled with questions, as she lowered her mouth, which is wide open.

  She then swallowed a bit of the penis head as she tried to suck it, the same as when drinking in her mother's milk; her hand was also holding the shaft si was moving from time to time.

  Her saliva was dripping down from Vdimir's shaft, making him feel cold and hot at the same time.

  Just like a vacuum, Seraphina just tinued sug it like a vampire waiting for milk to e out.

  But after 3 mihere is nothing, so she stopped as she leaned back, looking at the thing, which is now red and swollen from what she did.

  [Your dick just got sucked for 3 minutes.]

  [gratutions, Host. You have been rewarded 10 silver s and 10 dies.]

  The system notified him, but he was dead asleep.

  She then moved her small and slender fio touch the head, looking at it with questions.

  " my brother really produce milk? Why did nothing e out?" she said, feeling a little bit unhappy.

  While she was toug the head, brushing it with her fingers. Vdimir was feeling unfortable from the touch si's a little ticklish for him too.

  His eyes then began to flutter open as he leaned up from the bed with hazy eyes; he wao see why his little brother felt a little ticklish, like it was being tickled and teased.

  Seeing that it was her little sister between his open legs, he saw her gaze looking at his so called penis.

  She was even toug his little brother, making him a bit angry si feels unfortable but good at the same time.

  "Little sister, let go of my thing; it's so sensitive." Seraphina, who was ihought, did not notice that Vdimir was already awake.

  When she heard his calling, she was brought bad stopped her hands. "Sorry, big brother, it's just that. Seraphina wants to drink milk from yours, so I tried sug it the same as mother's breast," she said, looking down with a pitiful look.

  "Milk?" Vdimir, hearing her sister's words, was fused.

  "What do you mean, milk? I don't have milk," he asked, scratg his head and looking at her.

  Seraphina just gazed down at his rock-hard rod as she snorted. "Hmph, you are lying. I just tasted it, and it even tasted better than Mother. Please, you give me more, brother?" Seraphina looked at him with puppy eyes.

  Vdimir then remembered st night when he passed out some white milk, which the system called semen, came out.

  This made him uand that this must be what his sister was referring to. "Ahh, now I know what you mean about the milk," Vdimir excimed knowingly.

  With his loud excmation, Seraphina was very happy. "Really, brother, you give me more of that milk?" she said with stars in her eyes.

  "Of course, but it will take some time to e out. Just wait for a moment while I try pushing it out," Vdimir said to her as he clutched his shaft with his right hand and began his mission.

  ...

  I think you already know the mission ??
