Micha's feminine instincts reacted to the male hormones covering her tongue and filling her nose with an intensity too great to imagine it came from a child.
"~~~♡ It's spreading out like crazy here too."
Her eyes widened as the head expanded to create a great height difference.
"It's so thick… I bet it would stir me up all the way to my womb."
She placed the expanded umbrella in her mouth and wetly moved her entire head up and down. The kissing technique that always enslaved the boy was now directly applied to his erection, so his back arched below him.
"Ahh…ah…Micha-san…that's…amazing…"
"Eh heh heh…Hn…nh…nnnm."
Her soft, slippery lips moved up and down the surface of his shaft. Her tongue continued poking at the tip and her hand gently stroked the bottom of his balls. All in all, she pleasured him quite thoroughly.
However, he was not the only one crying out in joy. Servicing the sizable piece of male-smelling meat was enough to arouse her as well. As she continued her passionate service, she let out low moans and wiggled her hips.
Seeing that reminded Mutsuki that they were supposed to be washing "each other", so to distract himself from the pleasure, he grabbed at the chocolate-colored flesh positioned right in front of him.
When he massaged the two spheres, her hips swayed even more intensely than before.
(She's enjoying this, too.)
After grabbing it, he realized her butt was an important erogenous zone.
As he massaged that obscene flesh, her engorged flower petals completely gave up on protecting their precious contents and instead peeled back. The honeypot within even opened and closed its mouth as if it desired to devour something.
And more importantly…
"…Wow."
Mutsuki noticed something at the center of the mounds of flesh in his hands.
Due to their sixty-nine position, he could see her soft-looking anus with its elegantly closed wrinkles.
His upper body was propped up, so that exit was at the perfect viewing height as it wriggled as if breathing. The movement was intense enough to give glimpses of the poorly-lit contents.
Hidden deep behind her wild brown skin was some softer flesh the color of a young girl's lips.
The delicious-looking salmon pink filled Mutsuki with so much arousal a tremor ran through his body.
He gulped and then…
"Fyah!? Wait, Mutsuki-kun!?"
It happened so suddenly that Micha quickly spat out his shaft.
"Sorry. But your butt's so cute."
Mutsuki did not hesitate to press his face into her butt and his nose into lovely fleshy spot breathing at the center.
He made use of the tongue techniques built up by his deep kisses with her. He loosened up the flesh with saliva and heat as if parting each individual wrinkle.
"Nnah…ah…um, Mutsuki-kun, that's…that's…"
Not even that sexy young woman was accustomed to this type of stimulation, so the surprised sphincter quickly squeezed shut.
Mutsuki continued kissing and even sucking at the ring of muscles.
"St…stop… That's dirty…"
"There isn't a single dirty part of your body, Micha-san. …Nn."
He placed his tongue in the center of the ring and pushed it in to slowly expand the circle.
He knew it was not a clean place, but since it was Micha's body, he truly did not think of it as dirty.
That was how powerful an impression the woman had left on him.
He saw her as a roommate that knew how to get him to do what she wanted, a young woman that he could rely on, a mother that would envelop him, and at the moment, a beloved lover.
He wanted to kiss every last part of her plump body and see even more sexual looks on her face. Most of all, he wanted to make her feel even better.
With that thought in mind, he very, very thoroughly dug into her anus.
"Ah…wah…fwaaah…nn."
His thoughts seemed to reach her anus before the rest of her, but the anal caress finally began to fill her with a strange sensation.
The woman could not help but lewdly shake her large butt. She writhed from the clever caress that was Mutsuki's second talent.
"You smell so sexual, Micha-san. Even your asshole is erotic. …Ah, it opened♪"
His thorough tongue play almost seemed to melt her flesh and robbed her of the strength needed to close it. The sphincter was still stiff, so her anus swelled out like a volcano. His tongue sank into the sunken crater at the peak.
"Ahhhhhh…khhhaaaahhhh…♡"
A soft creature slipped in and out of that sensitive and supposedly dirty opening. A strange feeling welled up inside her and she began trembling from her thighs to her hips and her back.
(She's moaning in pleasure.)
Goose bumps covered the entirety of her round butt and something other than confusion filled her voice. Sensing that, Mutsuki felt a different sort of arousal that seemed to lighten his body.
(I want to do even more. Um…)
He searched through his memories for a way to make her feel even better than licking.
(Will a finger fit in?)
He decided to try to reach even deeper inside.
He gathered the remains of the soap to get his finger nice and slick. When he removed his tongue from the small entrance between her butt cheeks, it trembled like a small frightened animal, so he pressed the tip of the finger against it as gently as he could.
"Ahhn!"
But even that light touch caused it to slip in up to the first joint.
It felt like she had loosened up to welcome him inside. Both surprised and interested, Mutsuki pushed his finger in with a look of arousal.
Her squishy rectum was surprisingly soft. However, it seemed to be wriggling in fear of the foreign object, so he tried to relax her by using his second joint to massage the tense sphincter from within.
"Eeeeek! C'mooon… Not from inside…my ass… Ah, ah…hyaaaaahn!"
"Ah ha ha. But it gets softer as I mess with it. It's all wet inside too, so I doubt it'll hurt much."
"Uuh….. Nn♡ Nnn♡"
Micha screamed as his middle finger audibly moved in and out of her.
Once something caught his interest, he would investigate it as much as possible. Being on the receiving end of that kindergartner-level curiosity left her body on the verge of melting.
Simply slipping his finger in and out gave her an artificial feeling of excretion and the boy bent his finger even more to rub at and loosen up the sphincter.
A month before, he had been a virgin boy who could only tearfully cling to her, so she would never have imagined being pleasured like this by him. A mixture of frustration and pleasure enveloped her in a mysterious sort of ecstasy. She was unable to preserve her heart and could not stop her embarrassing moans. Her butt moved in circles all on its own.
Having that hole toyed with from the inside and outside felt undeniably good. She would have preferred he focused on her front side instead because this exclusively anal attack was unbearably embarrassing. Despite the lack of stimulation elsewhere, the anal pleasure caused her womb to tremble and her flesh flower to leak plenty of juices.
She had always known this area brought more pleasure, but she had rarely touched it out of embarrassment.
"Nh… C-c'mon…"
In order to get him under control, Micha used her pride as an adult to lower her head even further than before, swallowing his erection nearly to her throat. Her breasts and erect nipples pressed against his lower stomach.
"Fwah…"
Mutsuki gulped as he felt an intense sensuality cover his entire hips region.
