Two things

When I got close, I saw two things that surprised me. One was that Ava and my sister were sharing a couch. Ava seemed flushed as she was massaging my sister's feet. My sister, still with bed head and in her pajamas, looked perfectly content with ignoring the older girl, and was scrolling through reels on her phone.

The other thing that surprised me, was that mom was rubbing Della's feet! The two were sharing the second couch, and Della was much more particular than Tiff about her massage. I was shocked that she felt so comfortable ordering a woman twice her age to go harder on certain parts of her foot, or rub longer on another part, but I was more shocked by my mom submissively following all the commands. Every time she did, Della leaned forward and whispered something so just my mom could hear, and my mom's blush got deeper.

I also noticed that Della hadn't changed out from her run! This meant my mom was massaging her feet at their sweatiest. I think needless to say, but I was rock hard. As I got closer, I asked. "What's going on here?" Della looked up at me and smiled.

"We had a bet during breakfast." She said. "The winners would get their feet rubbed, and the losers would do the rubbing." She smiled evilly. I had no doubt that she had arranged the bet so she couldn't lose. Of all the girls, I had noticed that Della seemed to like dominating the other girls the most. I noticed it when she made Ava worship her feet. I hadn't realized that this desire extended to my mom. I also hadn't realized how hot it was to see my mom pamper the feet of my girlfriend.

"What about the other couch?" I asked.

Tiff spoke up. "Ava just offered to rub my feet on her own." Just like Della seemed to like having the others at her feet, I could tell that Ava liked being at others feet.

I was wondering what to do when Della spoke up. "I have a second foot, you know?" She smiled at me. "Or are you going to make your poor mother rub both of my sweaty feet?"

Seeing her angle, I was glad that I could date this girl. She certainly knew how to push my buttons. I sat on the coffee table and took one of Della's feet from my mom's lap. As I messaged, Della sighed. She clearly was enjoying this. She continued to criticize my mom's massage, and began to praise mine. I noticed that the more she did so, the more my mom appeared to blush. My mother and Ava still hadn't said a word since I walked in.

I was glad to be able to touch Della's feet again. It felt like it had been awhile, even though it had just been yesterday. My aesthetic obsession with her specific feet had faded, but I still loved them dearly. Furthermore, I loved the way she used them to get her way. I'm not sure how long these foot massages lasted before Della spoke again with a sigh.

"Alright now, boyfriend, deepthroat my foot." She said. "Show your mother an example of what I want her to do." Della had an evil smile as she looked at me.

My cock stood straight up as she suddenly escalated the situation. I looked to my mom, but she just gazed back at me with a submissive haze in her eyes. If anything, rather than surprise at the feet thing, she was surprised that Della called me her boyfriend.

Without thinking too much deeper on it, I opened my mouth wide and took all five of Della's toes into my mouth. Della spoke, "Deeper." Fighting my gag reflex, I continued to push her foot farther back in my throat.

Turning to my mom, she spoke. "Even though you were incompetent at the massage, I'm sure you could beat this guy at deepthroating." She said. "So now deep throat my foot, bitch." My mom and I, and probably Tiff and Ava behind me, were shocked to hear Della call my mom a bitch. Shockingly, my mom didn't refute her. In fact, she moaned at the insult like a bitch in heat before plunging Della's foot as far back in her throat as she could. I watched Della smile as she displayed her dominance. She took her foot out of my mouth and then she pointed it betwedn my mom and I. She looked between my mom and I, to Tiff, and said. "You. Come replace your brother." She turned to me. "Come hug me." I quickly sat behind her and pulled her into a supportive hug, allowing her to lean back and shove her foot as deep into my mom's throat as she could. Tiff was pretty quick in sitting where I sat, but she hesitated when it came to trying to swallow Della's foot. Della, seeing the hesitation, ground her heel into Tiff's sex. Tiff immediately moaned loudly, and I watched as a submissive glaze came over her eyes. She quickly took Della's foot as deep as she could into her mouth. Della now had both my mom and sister deepthroating her feet while Ava and I watched. I watched while hugging her, even. She had complete power over the situation. Della looked behind at me. She had been stroking my cock lightly ever since I sat behind her. "Which one of their feet do you want right now?" She asked. Slightly stunned, I was again happy Della became my girlfriend. Looking at my mom and sister, I could tell by the submissive glaze to their eyes that they would gladly let me do anything to them if Della commanded it. I weighed my options.

Mom's feet were a bit of an unknown variable. I only could tell that she had meaty and mature soles, but nothing of the deeper qualities like taste or smell. She would be a new experience.

Tiff, on the other hand, I knew well. Tiff had probably the most arousing feet to me if we only counted smell. She also seemed to tend to sweat a lot. I had been waiting since the night before to get back to her feet. Comparing her as an option right now, though, her feet were slightly smaller and bonier than mom's.

It was a tough decision.
