Nick's presence should help

"Zoe! I'm back!"

Nick locked the front door with a click, immediately kicking his shoes off and making way for the kitchen. Pulling out some leftovers from the fridge he got situated at the kitchen table. It didn't take long for him to finish his meal but the moment he did is when it caught his eye,

Glancing into the opposite room he saw Zoe laying across the loungeroom couch. Her feet, still encased in their shoes, slightly dangling over the edge.

Slowly getting up Nick approached her,

"Zoe? You alright?" He whispered.

Upon closer inspection Nick could hear Zoe's gentle breaths. She was asleep.

At that moment Nick spotted movement down Zoe's legs. He watched as they lifted themselves and, using the couch as leverage, her feet peeled her shoes right off.

"Ahh~" Zoe's left foot moaned. She turned and stared at Nick, giving him a lustful smirk.

Nick slowly walked over to the opposite end of the couch, sitting on the ground to be eye-level with his girlfriends feet. A smile crept it's way onto his face,

"Evening you two..." He leaned in, taking a long whiff of their smell.

"You like that?" Her left foot asked confidently before pulling herself forward and burying Nick's nose between her toes. He took another lengthy whiff, saliva forming in his mouth.

Her right foot chuckled, "She's been waiting for you all night."

"In those shoes?" Nick asked, kissing each toe on her left foot sensually.

Her foot moaned with each kiss, "Mhmm~ I know how much you like it when I smell like that..."

"Yeah... how was work with Zo-"

"Shhhh~" Zoe's foot pushed her big toe against Nick's lips before continuing,

"Don't talk about her, just worship me~"

Nick didn't need to be told twice. It was apparent that she was horny, even if Nick was slightly confused as to how feet could be horny. Regardless, he got to work giving her toes more kisses before employing the services of his tongue. He ran it over each toe, making sure to coat her digits in as much saliva as possible.

"O~oh.... suck them.... please~" Her foot begged.

Nick grunted, wrapping his lips around the big toe and sucking it vigorously.

"AHHH YEAH!" She cried.

More than anything her foot's moans were turning Nick on. And he wanted to hear more of it. He grabbed the whole foot, shoving as many toes into his mouth as he could, running his tongue across all of them to lap up their salty taste. Her foot scrunched her toes in complete bliss. Next to them Zoe's right foot was watching it all unfurl, a little pang of jealously hitting her,

"Hey uh... got room for one more?" She laughed sheepishly.

Still sucking on her left foot's toes, Nick stood up and presented his crotch to the right foot,

"Oh now we're talking!" She exclaimed before pulling forward and rubbing her sole against his tenting erection. Nick himself was moaning around the toes in his mouth, vibrating them. The left foot screamed from the overstimulation, making Nick jump. He quickly stole a glance at Zoe's face seeing if she had woken up. She hadn't. He immediately resumed pleasuring her feet.

Her right foot had rubbed Nicks erection to painstaking levels, and she knew it. Giving it a firm bite through his pants she grabbed the waistband between her toes and threw them to the ground. Immediately his cock sprang out like a puppy wanting to be played with and not a second later her right foot began tugging on it. Nick started thrusting into the foot, the feeling of her toes being way better than his own hands ever could. Moving his mouth down he started to lick her left foot's sole before eventually finding her lips. The two started making out, their tongues dancing around each other as they traded the salty taste of Zoe's feet.

Back down at Nick's crotch, Zoe's right foot decided to switch tactics. Pulling back she aimed her sole at his member before shooting forward and bringing it to her lips. Nick immediately cried out in pleasure as it felt like he was being given a blowjob. Her foot swirled her tongue around the tip before plunging it into her throat, a feeling that while pleasurable still confused Nick as to the anatomy of Zoe's feet.

Her left foot pulled back,

"Wow~ I haven't felt this good in years..."

Nick twitched from the stimulation below, "N~neither...hah..."

She glanced down at her sister before turning back to Nick, "Allow me to help you down there~"

Joining her sister the left foot started spitting on Nick's cock, rubbing her sole all over him. The right foot immediately did the same. What came after was something Nick had only ever had the chance to dream of...

Zoe's feet, coated in their own spit, wrapped themselves around Nick's cock, and began stroking him off.

They started off slow, teasing his member, feeling every pulse against their soles. But before long they had picked up the pace, sliding themselves up and down Nick's needy cock. They even threw in a few kisses and little nibbles through their motions. Nick was in heaven.

"...girls~?"

"Yeah?" Zoe's feet moaned in unison, Nick's cock still sliding against their soles.

"I~I'm gonna-" Nick stuttered.

"You can do it big boy~" Zoe's right foot said, voice dripping with sultriness.

"I'M GONNA CUM!"

Zoe's feet pulled back and faced their soles toward Nick's cock. They watched as it pulsed, shooting strings of semen toward them. It coated all over them as they wasted no time licking what they could from their bodies. Nick struggled to stay on his feet. He slumped against the couch for support before falling backwards and passing out.

Zoe's right foot looked over the couch,

"Will he be alright?"

"He'll come to~" her left foot smirked.

"Woah what are you-"

Before her right foot could finish, her sister lunged toward her. She began licking cum off her toes, even going as far as sucking on them while she moaned. The right foot proceeded to do the same, licking the lower half of her sister.

"It's a shame he isn't awake for this, he would've gone crazy over the sight," her left foot mumbled around her sister's toes.

Y~yeah..."

The left foot pulled back from the toes with a pop,

"There! Squeaky clean."

The right foot blushed,

"So..... what now?"
