There's one empty bed

None of you were trying to explain to your mom that you had a three-way relationship going, so a plan was made. Ava offered up her bed so that I could sleep while she went to Roxy's room. It was a lot of hoops but it was better than Roxy coming back to the only dude sleeping in her bed.

After the arrangements were made, mom made to go to sleep as she was tired from the drive up. Tiff decided to stay awake to catch up with me, while my two girlfriends went back to watching the bachelor. I ended up taking Tiff into Ava's room so we weren't disturbing Ava and Della's TV viewing experience.

Tiff sat down with her back to the headboard, and I sat at the foot of the bed, inches from her socked feet.

For a while, we shot the shit, her giving me the tea on mom and dad's latest arguments, and me telling her about how much better life is once you can leave home. Eventually, the temptation for me was too strong, and I probingly took one of Tiff's feet into my hands and began to massage it. Her socks were slightly damp with sweat, and as I kneaded her arch my sister softly moaned with pleasure.

"God that feels good." She said. "When did you get so good at this?"

I lightly chuckled in response, not trying to reveal my fetish so early. "I could rub them better if I took your socks off." I said.

"Then do it, big bro." She said in a brat-like tone. It was the same tone she used to get what she wanted when we were growing up. I'd be lying if I said hearing it now didn't turn me on.

I quickly removed her white mid calf socks, and was met with her feet. Like I mentioned, my whole family is tall, and Tiff falls under the category as well. With height comes big feet. Compared to Ava or Roxy's feet, Tiff's were huge. I silently imagined how thoroughly they could cover my face as I kneaded her now bare soles. She had her toes painted red, and she clearly took care of her feet with very little dead skin on her soles.

Tiff had lightly tan soles, and her feet were by far the sweatiest of those I had interacted with recently. On her left sole she had a single freckle at mid arch. As I massaged the knots out of her feet, continuing the conversation, I noticed a slight flush begin to creep up her neck. I was catching big whiffs of her feet at this point, and my god they stank. Good thing everyone who smelled her slippers earlier liked feet, because more smell tends to mean better smell for us who have foot fetishes. No wonder everyone said the slippers smelled good.

It was a good thing in my book for Tiff's feet to reek. It was a bad thing in my book because I was already throbbing through my pants at the smell. Tiff had her eyes closed and was softly moaning from the pleasure, and seemed oblivious to the haze of stink her feet were creating. The scent of vinegar and sweat was super strong and arousing.

Eventually, my arousal won out over my reason. I lifted one of Tiff's feet and dragged my tongue across her sole. I was met with a moan from her, and a very salty taste on my tongue. Tiff seemed to lose herself for a second as I got a second kick in before she realized what was happening.

"What are you doing?" She asked shakily.

"Making you feel good." I responded as I licked again, making her moan once more.

"This feels wrong." She said. "We're siblings..."

"It's just feet." I joked as I was met with yet another soft moan as I licked her sole again. It was clearly more than just feet, as both of us were getting off to it, but neither of us had to acknowledge it.

Finally, Tiff seemed to give in. She blushes as she looked me in the eyes and said with her signature bratty tone, "Lick my feet big brother."

And so I did. I went buckwild on her sole, turning so that I had one knee on the bed, one foot on the floor, and held her sweaty feet up to my face. I took a deep and shaky inhale of her feet, "God, your feet stink so good, sis." I said. She looked slightly embarrassed as I said it, making me chuckle as I dragged my tongue across her freckle. She moaned again, and I buried my nose into the base of her toes, deeply inhaling. God, I loved her stink. Eventually, I noticed her touching herself subconsciously. I redoubled my efforts and continued licking her feet, smelling as deeply as I could. I pulled my pants down below my cock, and watched the shock in my sister's eyes. I quickly slurped on her heel, though, and witnessed as her eyes rolled back in pleasure. Realizing the effect, I did the same to her other foot, and watched as my sister clearly came through her pants. The sight was so arousing that I was ready to cum within a few moments. I grunted as I held one of Roxy's feet to catch my cum. I inhaled deeply from the other sole, taking in as much of her scent as I could, and exploded. My sperm shot all over her foot, and up her ankle. As we both came down from our climaxes, Tiff held her cum covered foot before me. She looked at me with her big doe eyes, and said in that time that always got her what she wanted, "Lick it clean for me, big brother?"
