When I was standing behind the door while looking out from behind the window suddenly my younger step sister opened the door and she said to me.

"Oh wow! Onii-san, It's dangerous out here like that."

Then i said.

"Oh Umeka, I-i apologize..."

Then I said again.

"I-i think I'm depressed. what should I do Umeka?"

Suddenly my younger step sister closed the door and turned her back to me then bent over in front of me and she said.

"Here, look at my big and round plump butt cheeks and get excited. ugh!, I did it reluctantly Onii-san, but this is... embarrassing."

While my younger step sister holds her big and round plump butt cheeks with her right hand and showed off her black panties because her short denim skirt is slightly lift up.

Suddenly my younger step sister stomach growled and she pushing her loud, stinky, pungent, potent, and nasty farts without any warning in front of me.

“Nnngh…~❤️”

BBBBBBBBBBbbbbbbbbbbbBBBBBBBBPPPPPPPPpppppppppPPPPPPPPPRRRRRRRROOOOOOORRRRRRRTTTTTTTT!!!

Suddenly my younger step sister looked at me over her shoulder while blushing a lot and she said.

"Oh Onii-san, I'm really so sorry I couldn't hold it in any longer. I've been holding back from going with my female classmates to cafes earlier."

My younger step sister was still looking at me over her shoulder and blushing a lot waiting for my answer.
