Scraped Rin cum soak panty (Patreon)

This time, again a part of discontinued manga about how loli Rin playing with the
bully boys in the anime, found them with an adult magazine, copy what they see in magazine, they enjoy it.

They got suspicious by few people on how she go to isolated place with them, and she smells. 

They propose a plan to bully her about her skirt and tell her to wear a pant to cover it up.

The plan was succeeded and Rin started to develop her enjoyment of wearing cum soaked panty.

Time pass, Rin is now in a middle school. Still meet up with the boys, have sex, and soak her panty with cums.

Another time pass, Rin is in high school and doing school idol stuffs. Finding bit and pieces or her time to have sex with the boy in her idol costumes.

Yet another time pass, after the graduation ceremony they have a party and sex all night.

The last scenario would be Rin have a job as Ramen review columnist and pregnant with the boys. All the boys volunteer to be the father, Rin want them all to be her husbands despite they will be shunned by the society, then they heard the commercial about the new city that support Polyandry. So they decided to move there. THE END.

But I stop drawing it because I can't figure out on how Rin's mother didn't notice the cum smells and stains and to make loli Rin, middle school Rin, and high school idol Rin pregnant and Rin's children canon to the story.
