Josh wants more

Monica has no time to text one of her friends before Josh pounces on her and fills her once more with his incestuous cum. Monica has always been the smartest of the two siblings and neither are worried about her skipping class.

It is now almost ten and the loving siblings still haven't gotten out of their cum-stained bed. As his sister/girlfriend contemplates whether she should still go to school, Josh decides that he still wants more of his sister.

"Why won't you just skip school for today, sis? Staying at home for only one day won't hurt anyone. And besides, are you sure you want to stop what we are having right now? I am not." Josh seduces his sister as he gropes and massages her breasts.

"Eager today, aren't we?" Monica teases as she groans from his ministrations. "Gods, keep this going and I will probably sport a baby bump by the time I graduate."

Hearing the word 'baby' awakens something primal inside Josh. His mother had him when she was still in high school, and was pregnant with Monica when she graduated high school. Something inside him whispers that it is such a shame that Monica hasn't given him a child although they have been fucking even from before they are dating. But now Josh can make up for it. There is still a chance for Monica to be pregnant at her graduation, or even time it close to her giving birth to his child.

"Oh, what is this? Big brother gets excited at thinking about impregnating his little sister?" Monica coos as she grabs Josh's now hard dick again. "Does big brother want to pump his little sister's womb full of his seeds? To breed an army out of her fertile womb?"

If Josh isn't hard before, now he is obviously hard and more now. Something about the word 'breed' turned him on, an image of successfully breeding his sister portrayed clearly in his head. It was such an animalistic word - breed. To successfully fuck a girl until she is with his own child, his own little sister at that. The feeling is beyond intoxicating. It made him feel like a man.

"And what if it's a yes?" Josh dares to ask. He knows his sister would prefer to finish her degree first before committing to anything, but he can't help to ask.

"Hm... I don't know... If I am not on birth control maybe we could just go on and see how it turns out? In the meantime I will enjoy this riskless bareback sex as long as I can." His sister answers as she proceeds to get up and slip Josh's dick inside her pussy again, her back facing him.

Moaning from pleasure, Monica proceeds to ride his cock again in reverse cowgirl, obviously excited as well from the thoughts of being bred by her own big brother. Josh takes the opportunity and sneakily reaches for his phone. Opening the app, he quickly scrolls through the seemingly endless list of rules until he finds what he is looking for and changes them.

• There is no such thing as birth control. Cumming inside a woman's pussy always carry with it the possibility of pregnancy.
• The possibility of pregnancy is tolerated and often even embraced. Every birth from an incestuous union is seen as a gift.
• In relationships, the men decide when it's time to have children, impregnating the girls, who are happy, willing, and excited to have a child, regardless of the couple's current status in life.

He also adds a few more rules for a good measure.

• It is a norm for a girl to be pregnant before or by the time she graduates high school or sometimes college.
• The norm of incestuous union is between brother and sister, although other forms of **** is accepted.
• There is always an equal number between brothers and sisters in a family to make it fair for everyone.

What can Josh say, he is a greedy man. If he can have the cake, he will eat it as well. Josh submits the changes and watches the white light, same as the one before, as it fills the room. He can't wait to pump babies over babies into his sister.
