自购，喜欢可以考虑购买原作：

有大佬可以帮忙跑个四人孕肚图吗？这一家还挺多人的，就是剧情戛然而止了，没一个后日谈，或者摆几个测孕棒之类的分镜。你就这样开完趴就走了，我们看什么？

[Synopsis]

After confessing to his childhood friend Anna and getting rejected, the protagonist, feeling desperate, impulsively ordered a certain item online.
“A remote control that lets you manipulate anyone at will.”
He regretted making such a pointless purchase but since the item had arrived, he decided to go to Anna's house anyway.
However, Anna wasn't home and her younger sister Nanami answered the door, giving him the cold shoulder.
“Take off everything you're wearing.”
“Yes.”
“Lie down on the bed and spread your legs.”
“Yes.”
Half-doubting it would work, Nanami obediently followed the protagonist's every command without resistance.
He thrust his cock into her exposed pussy without hesitation and fucked her.
Just then, Anna returned home...

Enjoy harem play with the childhood friend family, now completely under the protagonist's control via the remote.
-----------------------------------------------
