Ayu-nee, look at me.

Ayunee is rough and insensitive. Maa-kun is delicate and sensitive.
Having become siblings due to their parents' marriage, they got a secret.

Getting aroused toward Ayunee's glamorous body as usual, Maa-kun
can't help pulling it out of his pants and demanding fellatio.
Ayunee had ignored him in the first place but his persistence
finally makes her give in and put it in her mouth.
Although her fellatio is rough, he cums in no time...


"Maa-kun!!"
Ayunee's voice is calling.

Soon she rides on Maa-kun and shows her c*nt to him.
"Look, I'm already this wet..."
