“I don’t mind teeth.”

I tried not to smile as I sucked on his head, already it filled my mouth nicely and was slowly getting thicker. I pulled back and looked up at him, “I suppose you would have to get used to teeth with something this big,” I told him.

I started to suck on his head in earnest, his hands sat awkwardly by his side, as if he didn’t know what to do with them. As he got thicker I started to use my teeth softly, turning my head to graze against his cock.

“You don’t have to be so gentle,” he told me.

I stopped again and looked up at him, “How much do you like teeth?” I asked him. He blushed, it made me laugh, here was my brother, cock out with his slut sister on his knees and talking about teeth made him blush. I looked around the room quickly as an idea came to mind, “You’ve never been balls deep in a woman’s mouth before have you?”

He laughed, “Of course not.”

“Close your eyes, and no peaking, I have an idea, which I think will make you feel very nice.”

He did as I asked, and I stood up. I grabbed my purse and pulled out a couple of hair ties I always carry with me. I walked across the room, taking the opportunity to pull my panties off and grabbed one of my father’s favourite possessions from the mantle. A large wolf skull.

I fiddled with it for a minute as my brother asked, “Kim what are you doing?”

“Shh,” I told him, “be patient, this is going to be something special.” I looped the hair ties together then hooked them around the back of the jaw. They pulled the wolf’s lower jaw up, closing it. I tested with my finger, it wasn’t a lot of ****. “This has got to be the kinkiest thing I have done,” I said aloud.

“What? Sucking your brother?”

I laughed, “Nope, I’ve done kinkier things then that. I pulled the wolf skull over my head, it was damaged underneath, where the spine should enter the skull. It wasn’t a perfect fit, but it would work. I then went back to my brother and knelt again. I could hardly see, but that didn’t matter.

I grabbed his cock, still quite hard, and stroked it a few times, then using my free hand I pulled the jaw open and fed his cock into the skull. As the teeth rubbed against him he moaned and hardened more. Soon his cock was pressed against my lips again and I opened up for him, stretching my jaw to accommodate his cock.

I let go of the wolf’s jaw as I did and was rewarded with another deep moan from Jethro, “What the fuck?” he asked quietly. I started to bob, sucking his cock head and sometimes nibbling as the wolf’s teeth rubbed him. With the length of the snout and the bit I had in my mouth he was almost balls deep.

I pulled back slightly so I could talk, “Open your eyes in five seconds,” I told him.

I opened my mouth wide and pushed forward taking his huge cock head into the back of my mouth, he plugged the entire entrance to my throat with ease.

Then he must have opened his eyes as I felt him thicken more as he moaned…
