Ask her some questions

"Rin-slut, I forgot to ask. Do you have any family or close friends? Hot ones, I mean. I really need a bedwarmer with a tight ass and it seems like my friend here wants you for himself." Motohama asks.

"Yes, I have a sister named Sakura, a girlfriend called Arturia, and my boyfriend have two sisters named Kuro and Illya as well as their mother Irysviel." Rin answered between deep breaths as she was taking the pounding to her previously virgin ass.

"Sweet, do you have any pictures of them?" Motohama asks.

"Right here in my purse, my boyfriend bought me this infernal device and there are some pictures of them here." Rin said giving the unblocked smartphone to Motohama. She did not have any sort of password since she would likely never be able to use it if there was any and even so she barely could do more than answer and give calls to others.

Motohama gladly took the smartphone and began looking over at each of the pictures. Everyone in them was drop-dead gorgeous. Especially the ones from this Sakura, she looked delicious in all aspects, but the woman beside her was even more so. She had long purple hair reaching her big ass, the most magnificent breasts he has ever seen (and he was used to Akeno and Rias' bountiful heavens!) and her eyes were mesmerizing.

Actually, not a one of them was not wonderful.

Realizing this he decided to speak up.

"It is normal for all the beautiful women connected to you to do all in their power to come to my house later today to serve me in any way I desire and no one will find it strange." Motohama said, already thinking on how this would go.

However, there was a more pressing meter for now, he was getting horny from seeing Rin being pounded like that and he wanted to bang some ass right now. He began looking around for a good target for his desires when he saw one perfect target right there.
