Chapter 11

Sylvia bit her lower lip at the enjoyment of the tongue in her ass. Not just because of the feeling of that soft, wet tongue wriggling around in her sensitive, filthy hole. But also because that soft, wet tongue belonged to our 15-year-old niece. There was something so utterly depraved; so utterly filthy about being in her living room, on her couch, naked save for the nylons on her lower legs, and being on her hands and knees with her ample ass in the air, and a family relative of teenage youth having her hot mouth on her bung and her nose against her humid crack, inhaling the fragrance of her own aunt's ass.

Our niece Tamra was acting rather shy not too long ago today, but right now there was virtually nothing left of that shyness, and if anything proved that, it was the absolute vigor and power of her tongue working on my sister's shithole. Groaning, almost grunting, the younger girl was basically clawing into her aunt's fleshy ass cheeks and squirming her tongue over the clenching red muscle that gave access to Sylvia's bowels. The tip of Tamra's tongue prodded and lapped over the wrinkled, pulsating star, and applying considerable force would dig it fairly deep into her aunt's greasy shit pit.

Whipped along by the odor of Sylvia's butt the teenager was beside herself with youthful lust and ate out her aunt's crapper. Her saliva wetting the little hairs surrounding Sylvia's anus and having them matted against the dark, soft skin surrounding her asshole, the need seemed to be obvious by the girl's loud panting coming from her open mouth and the lust-ridden grimace on her teenage face as her tongue tried drilling deeper into her aunt's tightly grasping anal orifice.

Our blond niece was getting wilder now, as she bobbed her head back and fro; her head making fucking motions in order for her tongue to reach deeper and deeper into the entrance of her aunt's guts. Sylvia could do no more than grunt and groan, spittle leaking from the corner of her mouth, and try to keep her anus relaxed so as to allow her niece to get her tongue deeper into her shit pipe. The hot breath coming from Tamra's mouth and washing through the crack of her ass only made the whole thing feel better than it already did. It served as a bonus, another reminder of having a real, breathing mouth on her rear end.

"Ohhh Goddddd..." Sylvia whimpered. "So gooddd, So hottt having your tongue in my asshole. It's so fucking hot. So fucking nasty. Oh fuck, Tamra. Keep fucking that shithole with your tongue. Tongue fuck my fucking nasty shitter. Stick your tongue all the way up your aunt's filthy butt hole. Taste it. Just fucking taste it. Taste my fucking ass. Fill up your mouth with the taste of my fucking ass. Shit, it feels so good having your face in the crack of my ass and your mouth on the hole I shit from. Keep tongue fucking the hole I shit from, Tamra. Stick your tongue ALL THE FUCKING WAY up the nasty hole I SHIT OUT OF. Get my ass juice all over your tongue. Suck that filthy juice out of my ass; your aunt's ass. Jesus Christ, Tamra. Taste it! Shove that tongue deeper and taste my shit. I want you to taste my fucking nasty shit. When you're done I want to tongue kiss you and taste my shit on your tongue."

Vile word after vile word came from my sister, delirious with depraved incestuous lust as her 15-year-old niece seemed to give her the rim job of her life.

The words became filthier and filthier, and Tamra got increasingly turned on by them, reveling in sharing this nasty experience with her aunt. She felt like a woman rather than a girl. A woman doing perverted, filthy, grown woman things. The fact that most grown women did not engage in this sort of sexual activity with their relatives did not dawn on her. As far as the teenage girl was concerned, if not many aunts and nieces did this sort of thing, they certainly should, because they're missing out on something hot and great and deliciously nasty.

Me, I just couldn't stand it any longer. I couldn't stand staying here in the hallway behind the door, merely jerking myself off and merely watching. I wanted to be a part of it, I wanted to participate. I wanted to do anything, if not yet get involved with Tamra, at least to help her be nasty with my sister. At least let her get used to me being part of this whole thing. Maybe keep Sylvia's ass cheeks widely spread so Tamra could concentrate on sliding her tongue in that sucking hole, and I could see up close how it disappears into that brown hole, and reappears from a gaping, wet shithole that slowly closes before speared open again with that teenage, pointed tongue. Whatever, I just HAD to become part of it.

And so I pushed the door open and walked into the room, stark naked and hard cocked whipping from left to right, my feet silent on the carpet as I approached my niece from behind. My niece, whose blond hair was flailing around as her head bobbed.

Within a flash I was beside my sister on the couch, grabbing a butt cheek in each hand, and spreading them wide apart. Tamra had retracted her tongue from Sylvia's gaping asshole with a loud plop, and with wide, surprised eyes she looked at me.

"Don't worry, Tamra," I said softly with a smile. "I've been here for a while, and I've been doing this with Sylvia for a while too. I'm here to help and to join you. Nothing you don't want to do will happen, and everything you want to do will happen."

My heart was pounding, realizing there was always a chance that Tamra would freak out and run out. Sylvia too, was silent, waiting for something to happen.
