Chapter 13

Everything within me tells me to get the fuck away from her, but I must fight through it. Anything’s better than having her return to my asshole and I can deal with any indignity. The smell is pungent as I get closer and hope she tells me this is all some kind of sick joke.

My tongue presses against the ridges and the bitterness is a little stronger than when I sucked her fingers. I ignore the impulse to vomit again as my tongue starts to slowly circle the center. I’m hoping this is enough, since I don’t want to get any closer to her hole.

She starts to sigh as I go over the same ridges countless times and the taste of bitterness can no longer be found. The smell is still horrendous, but at least it’s not the added assault on my tongue. I try to will my mind to take me some place else, but it doesn’t work.

Her voice still sounds sharp, but there’s pleasure there as well. “That’s enough for now, sister.”

My tongue pulls back quickly and I lean back a little with my eyes fixed where she wants them. I’m sick inside and wish she could see reason, but there’s nothing reasonable about her. There’s a madness that can’t be overcome and I wish there were some way out of this mess.

Cin’s voice shows a hint of the madness my brother married and I wonder if he has any idea who she really is. “Did you like licking my asshole, sister?”

I can’t tell her the truth and have to play along with the sick game. “I liked licking my sister’s asshole.”

Her voice takes on the roll of commander. “Get back to it.” I press my head forward again and find my tongue circling her hole as she sighs. “Rub my clit, sister.”

My fingers move up without delay and they are soaked immediately from her dripping. Cin starts to moan softly from my actions as her clit feels pleasure from my touch and I want to get this over with quickly. I move my tongue a little quicker and hope her moans increase, since I want to be done with this.

Her body still has a way to go and I decide to try something new. My tongue presses to the center of her asshole and find just a hint of something bitter there. It feels oddly pleasant, much more so than licking the ridges, and her body starts to tense a little.

She grabs the back of my head and forces me to enter a little, but it’s not enough to taste anything unpleasant. My fingers work her clit as she starts to drip onto my tongue, which is a more pleasant taste by far. Her moans become louder as I try to fuck her asshole with my tongue, which seems to push her closer to the edge.

I feel her asshole tighten around the tip of my tongue and the strong scent of her orgasm is no longer something that makes me want to gag. Her release starts to coat my tongue and I can taste a little more of the sweetness mixed with something salty as she continues to contract around the tip of my tongue.
