Once upstairs, Danielle went into her room without another word. I remained in the hallway, Looking at her closed door with some serious confusion roiling around my head.

Gingerly, I brought my fingers up to touch my lips, still feeling lingering aftereffects of the kiss she'd planted on me, unlike any we had ever shared before. ‘Get a grip,’ I told myself. ‘This is Danielle, your sister.‘

I squeezed my eyes shut, willing away the illicit thoughts from my mind. And still with my eyes closed, I managed to relax my facial muscles and let out a long, long sigh...

Then I finally let my left hand go to the door of the room I shared with Amber, and I turned the knob. A good night's sleep would clear my head.

I opened the door, and my eyes settled in on a familiar sight. Yet no matter how many times I saw it, I would never, ever get sick of it.

Amber's naked ass was pointed back in my direction, the creamy white globes separated by a shallow valley like the sweetest peach imaginable. I could even see the delicate pink flesh in the middle which promised to taste even better.

Of course, someone else was already tasting it. E-Beth was flat on her back across the bed, her head between Amber's thighs as she wriggled her mouth against Amber's crotch. The half-hard erection Danielle had already given me was quickly rising to full mast.

Mindlessly, I let the door close behind me with a muffled thump as I sagged back against the handle. The sharp sound was enough to startle the Sapphic couple on the bed, and E-Beth quickly Looked over to me while Amber craned her head around to take a Look.

"You're home early," Amber stated. "I thought you were out with

Danielle?"

While the sight of Amber and E-Beth in a torrid sixty-nine was still enough to send me into a stupor for a moment, I was too familiar with them to be stupefied for long. I shrugged and offered, “And I thought you were studying.”

“We ARE studying!" E-Beth smiled and then took another lick at Amber's slit.

“Anatomy IS a subject... sort of..."

Amber's sharp blue gaze then dropped to the vertical bulge in my jeans.

"So is that for us?" Her teeth shone in a pearly grin.

“Or for

Danielle?"

“Stop it," I waved her off. "She's my sister." I started moving into the room, casually pulling off my shirt.

“A sister with a hot bod..." Amber continued.

I glared at my girlfriend, communicating with my eyes that I wanted her to drop it.

“Come on. Don't tell me you haven't thought about it. I KNOW you've seen her naked plenty of times."

"Yes, plenty of times. And nothing has ever happened," I said firmly. I walked up to the bed, now topless, and Leaned down to peck Amber on her lips.

She received my kiss, but then rolled off of E-Beth and then spread her legs for me, dipping her fingers down to also spread her pussy Lips.

“Don't you want me, little brother?" she asked in a high-pitched baby voice. "Isn't my pretty pussy exciting to you?"

My back went stiff as my moral center went to war with my hormones. I couldn't help but gasp, "Oh, gawd..." as I closed my eyes and briefly pictured Danielle in Amber's position.
