I only speed read this story... that's the disclaimer.
Bodied Yuuka-nyan came to anon's house to beat a stray family doing house declaration. When Anon said he doesn't ask an extermination, Yuukanyan starts (pretend) crying, so he gave her chocolate.
Before leaving, Yuuka-nyan gave the anon a small socks. That's from the bodied Flandre in the picture. Yuuka-nyan then beat the Flandre again and steal her underwear.
Anon usually don't care about yukkuri, but he really feels sorry for that Flandre and gave her orange juice then take her as pet.
Anon tried buying new panties for Flandre, but Flandre refused wearing any panties until she can get back on that Yuuka-nyan. In the mean time, Anon got that look from peoples around accusing him as a yukkuri pervert.
The story ends with Yuuka-nyan's voice. "Sell this to you for 5000 Yen nyan"
