Entering From The Backyard

"Then, what if I were to grope your ass when your husband is right in front of you, Nina?" Kafka lost the gloomy look in his eyes and asked with a devious smile on her face as his hand got closer to the sinkhole hidden in her butt. "What if I were to absolutely tear it apart by digging my fingers into your meaty behind and twisting your rear like I were trying to take a chunk of your flesh?"

"...Would you shout out and ask your husband to help you out, or at least let out a little plea to make me stop?...Or would you keep silent and get manhandled in front of the man you share a vow with, like the good girl you are?" 

Kakfa eagerly asked as he finally reached the end goal.

He immediately realised this when he felt his fingers leave the moist part of her inner butt and suddenly touch some sort of ring shaped entrance, which was even more moist than what he had felt before, almost as if the plump ring was filled with a sweet juice.
