"Elsa. From now I'm going to insert my cock into your older sister's anus. Watch carefully."
"Y-Yes."
I brought the glans close to the anus.
Then Elsa leaked a flustered voice.
"I-Impossible! …Masaharu-sama. After all, such a thick cock cannot enter such a small hole."
"It's fine. Your older sister is a masturbation-loving perverted woman, so she's become soft so she can easily accept a cock."
"That's a lie. Onee-san burns toys before she cums when she uses them, so she should only be able to masturbate with her fingers. A cock thicker than a finger cannot enter."
Elsa seemed to be worrying about her sister's body.
The older sister spoke in a gentle voice to reassure her little sister.
"Elsa. It's fine. So watch carefully as a cock is inserted into my anus."
"…Yes."
"Then I'll put it in all at once."
Zunyu.
"Ahh! The tip of the cock entered! It will burn!"
