Making My Master

We spent the next 2 weeks making out. Anytime I had the chance, I asked, and you were happy to oblige. You weren't ready for much of anything else, which is entirely okay. Being your sister's master, and having your sister wanting you to use her, would be a big hurdle for anyone. Getting to kiss you was more than enough.

We also worked on making you be the master I know you can be. At first you couldn't bring yourself to tell me to do anything!

"Master, what clothes should I wear today?"

I had gotten up the nerves to walk out into the living room naked. Your eyes did their absolute best not to look at me, but you couldn't stop them.

"Sis... Umm... Why are you naked?"

"Well, I'm just a pet, and I'm not allowed to put on clothes unless my master picks them for me."

"I don't think that's true."

"Yes it is, I'm pretty sure my pet classes taught me that."

So I walked you to my bedroom and had you pick me out some clothes. You were so adorably embarrassed the entire time! I was too, to be honest, though my main reaction was to be turned on. I was so horny from you seeing me naked, that instead of cuddling with you right after like I was planning, I had to have you leave my room for a bit.

The next day, we were cuddling like normal, fully clothed. This time I was sitting in your lap with both of your arms around me.

"Am I being a good girl for you, master?"

"Yes, sweetie, you're a very good girl for me."

"Sweetie?"

I was surprised, you had never called me sweetie before.

"Do you not like it?"

I thought about it for a moment, and the name made me felt safe and cared for.

"No, I like it," I responded with a smile. We kissed for a little bit before I asked a question.

"Hey, bro, you know you can touch me wherever you want, right?"

"I know..."

"Like right now, while I'm fully clothed, so it isn't the end of the world. Most petgirls love to be petted on their chest by their masters, it wouldn't even be seen as weird."

You looked a little worried, so I just snuggled up a little closer to show you this wasn't a big deal.

"...Okay, sis, I'll try."

You first started petting my arms and shoulders like normal before slowly moving towards my breasts. First, you just stroked them as if they were any other part of my body. I wasn't wearing a bra, so you could definitely tell that my nipples were a little bit hard. Eventually, you got up the courage to lightly squeeze them and test their weight. I couldn't stop making small little sounds from the feeling.

"Well, those noises are pretty adorable."

I felt so happy being complimented, I was being a good pet for my master.

"Your hands feel so good..."

You smirked, but didn't respond. I let you continue playing with them for a few more minutes before speaking again.

"You know, no one else has ever actually gone this far with me before. They've been touched, but not this much."

"Wait, does that mean you're a virgin? " you asked with a shocked look on your face. I nodded shyly.

"Didn't you have boyfriends in high school?"

"I did, but none of them ever felt right. I never let them do anything but kiss me. None of them lasted very long, they weren't the right guy for me."

"Am I the right guy?"

"Yes, master, I saved myself for you. I didn't know at the time, but it was all for you."

I saw a look of understanding and care in your eyes before you gently kissed me, all while continuing to play with my chest. I felt you get a little bit hard underneath me, and I don't know if it was because of you playing with me, or if you loved the idea of being my first time. Either reason would be great to me, but I didn't ask. I didn't want to make the petting stop.
