Once in the bathhouse, Sonic had to carry his basket of shampoos he got from his sister.
Sonic also got some bath supplies while entering in one of the showers.
"I better shower this white stuff off of my legs before someone sees." Sonic said as he turned on the shower.
Warm water dripped on his body. Sonic then gets a sponge out of his bath supplies as he squeezed a drop of soap or two on the sponge.
He scrubbed his inner thighs with the soapy sponge.
Though during doing it, to his horny surprise and strange desire, he imagines Knuckles hands on him while moaning in pleasure as he blushed.
His imagination was so frisky and horny that he failed to noticed Knuckles looking at him.
"Oh~so firm and so hard. Feeling so good." Sonic said with a blush a as a moan escaped his mouth while drooling and his tongue sticking out like a dog.
"Uhh Sonic?" Knuckles voice said as he spooked Sonic as he gasped and saw Knuckles with a towel and sponge.
"Oh you startled me Knux." Sonic said while taking a deep breath.
"Sorry about that. I had to be here due to the fact that I have some sticky white stuff a little." Knuckles replied.
"Oh. Heheh. Knux if you want to be in the shower with me all you haft to do is ask." Sonic smirked sexually before he pulled the red echidna in the shower with him.
"Umm Sonic look, don't get me wrong I will agree to date you in secret but are you sure?" Knuckles said hesitantly.
"Knux, Of course I'm sure. I mean I known you first before Tails, Amy, or anyone else. Besides what doesn't kill them wont hurt us." Sonic said with ease.
"Oh, Okay. I mean yes we have known each other first even after when the prophecy was fulfilled and done with. Though it's a miracle Eggman didn't tell anyone about... you know." Knuckles said while caressing Sonics face.
"I know. Besides I think your cute anyways." Sonic said as he looks down shyly.
"My Great-Grandfather will have a heart attack." Knuckles thought.
"Ehh, don't tell anyone I told you this but... Your actually cuter than your sister." Knuckles said 'trying to compliment Sonic properly'.
That alone made Sonic blushed a bright red before he thanked him as he chuckled.
"Thanks Knux." Sonic said before kissing his cheek.
Knuckles felt lucky. They realized they have been in the bathhouse for 30 minutes before beginning to rinse and wash each other.
Though there are parts that they enjoyed touching.
Knuckles felt Sonic rubbing his crotch with a sponge while the two rinsed off.
"If your good at fucking me drunk though you might be ever better fucking me sober Knux." Sonic said with a seductive tone.
"That a bet babe?" Knuckles asked with a smile.
"Why don't we find out tonight?" Sonic asked as he placed a hand on his chest.
"Sure thing Sonic. But let's finish bathing and get out." Knuckles suggested while blushing.
"Good idea. Though in my honest opinion my Uhh scarfs gonna be at the cleaners." Sonic said honestly.
Once they finished bathing, they exited the bathhouse.
