The first time

Three days later, when Conceus was training, Philotes came to find him.

"Sister, do you feel better?"

"I'm fine, but still far from full recovery."

Conceus turned and tried to pretend he's focusing into swinging sword. Damn, her body is so seductive!

Philotes was wearing an almost-transparent dress. All her private places could be seen. Her hips, her boobs, her ass, every part of her body combined to create an irresistible charm even for girls. It's not that he hasn't seen her in this appearance before, but today he had to use all of his willpower to avert his gaze from her.

When he's distracted, a hand suddenly grabbed his cock from behind: "Oh my, what do we have here? A cherry that hasn't been popped."

Even her breath smells so sweet! "Sis, I... I haven't finished my training yet."

"I'm the goddess of Sex, yet my own brother hasn't had any experience of it. I feel so shame."

"That's because... I haven't met any girl yet."

"Isn't that there is one currently standing in front of you?"

"Sis, do you know what you're saying."

"I'm serious. My divine power is still weak, and having sex is the only way to make it grow."

Conceus understood what she meant. Like muscle could be developed by training, divine power would grow if it's used frequently. However, he never thought about her as a mate. His family was very precious to him, and he feared this connection would change.

He took a step back from her: "It... it's too sudden. Please give time to think."

She smiled wickedly: "You can't refuse me."

Suddenly, the air was filled with aroma. Conceus knew Philotes just used her divine power, but before he could say anything, his mind was filled with an uncontrollable sex drive. He let out a roar, pinned his sister onto the ground and tore her clothes apart.

Philotes didn't show any resistance. Instead, she shouted: "Yes! That's right! Ravish me! Let the beast inside your heart come out and eat this defenseless prey!"

Conceus rammed his fully-erected cock into her pussy. It went through smoothly, as her insides were already wet.

"Congrat of losing your virginity. Now let me teach you how to please women. In, out, in, out... that's right, good boy..."

Conceus mindlessly followed her instructions. His only sensation now is the warm flesh wrapped around his cock. Two genital perfectly fit, like they were molded. Her cunt definitely had the ability to adapt.

"Now, faster... Yes! Yes! Yes! You're a genius! Fuck me harder!"

With each thrust, his cock went deeper and deeper. When it finally penetrated through her cervix, Philotes let out a loud moaning as she reached climax. Her orgasm was so hard that her divine power's effect disappeared. Conceus regained his mind and realized what he's done.

Philotes breathed heavily: "I think your unknown attribute must be 'Sex' like me. When I go out I must order my temples to make your statue. We can be worshipped together..."

"Sis, can I pull out?" Conceus felt that his lower half was full of pressure. One slightest stimulus and it would explode.

"It hasn't reached the good part yet, at least not for you. Now, release it all inside me. "

"Are you sure today is your safe day?"

"Of course not. I tell you to shot inside because today is my dangerous day. Otherwise, it'll be meaningless."

"Why... why do you do this?"

"You help me, I help you. I heard from Mother that you have the attribute 'Childbirth', right? If you want to make your divine power grow, you'll need a pregnant woman. Do it! Make my belly swell with your baby! Our baby!"

She reached out to his balls and massaged it. That's the last straw: Conceus roared as his immense load of semen shot into her waiting womb. Philotes moaned: "Ahhh! This sensation! Feel your hot cum overflowing in my uterus... I love it!"

She knew for sure right at this moment, her ripen egg was floating in her womb, besieged by countless of her brother's sperms which were doing exactly what their owner did to her earlier: ripping through the outer layer, drilled deep inside until becoming one with her. That thought made her feels really exciting.

Seeing Conceus has collapsed, Philotes gently lifted him and placed him on a grass bed. Suddenly a shiver ran through her body.

Being stimulated by the hot baby-making liquid of Conceus, her inner walls became very sensitive. She could sense that there's something had just implanted on her uterus, taken root and absorbed nutrients from her body.

Philotes rubbed her flat belly: "My child, take your time to sleep well. Because in the next nine months it will be a bit noisy there."
