Suki on her stomach waiting

When I got back to the bedroom, I saw Suki waiting for me lying on her stomach. Her skirt was flipped up showing off her cute, little ass. "Are you ready for me, Master?" She then reached behind her and spread her ass so I could see her tight starfish. My cock twitched at the sight as I joined her in bed. She definitely didn't seem to have the nervousness she had before.

"You definitely seem eager," I said as I rubbed her butt.

"I just want you to be able to enjoy everything my body has to offer, Master." I squirted some lube onto one of my fingers and slowly worked it up her asshole, causing her to moan. "That feels so goooooood!"

"Have you really not had anal sex before, Suki?" I asked as I slid my finger in and out of her ass.

"I have never had a penis enter my anus."

"Then, what has entered your anus?" It really amused me just how proper she could be with me finger fucking her ass.

"Fingers. Small vibes and toys. As I said before, nothing larger than a finger has been inside me."

"Oh really?" I pulled my finger out, put lube on two fingers, and worked them up her ass. I had to admit, her ass was very tight!

"Oooooh! Is that your cock, Master?"

"No, that's just me adding a second finger. So, part of your training was them playing with your ass?"

"Yes. Mostly to get us accustomed to anal penetration. But also to grade us based on our response to it?"

"Grade you? What do you mean?"

"Not everyone can enjoy anal sex. Grade 1 were the girls who just couldn't find any pleasure with anal penetration but they were still trained to accept it. Grade 2 were the girls who did learn to enjoy anal penetration but were unable to orgasm from it. Which leaves Grade 3, the girls who did have anal orgasms."

"Hmm, I didn't see anything on the site about that."

"Well no, that information wouldn't be available. After all, some people wouldn't pick a girl if he knew that she hated having anal sex with him. Though I suppose some individuals would especially want a girl that hated it. But I'm happy to tell you that I was Grade 3!"

"So, that's why you're not nervous this time? You know what you're going to enjoy getting your ass fucked."

"Actually, I'm not nervous because you've shown that you won't hurt me. Your cock is so much bigger than anything that's been in my ass so you could still ruin me if you wanted to." She looked back at me and smiled sweetly. "I trust you and I want to do this for you. Even if I was Grade 1, I would still willingly take your cock in my ass."

With that, I rubbed a generous amount of lube on my cock and put the head against her backdoor. "I think you're ready. I'm going to take your ass now."
