Chika, who had not visited the back alley in a long time, ended up giving money to a man and providing him with services. Perhaps because she had not been there recently, the man’s penis had not been washed for days and was in a dirty, foul‑smelling state. This was a situation that most women would avoid. In reality, Chika also felt plenty of disgust and discomfort deep down. Nevertheless, having smelled the scent up close, Chika had her female instincts aroused, causing shivers down her spine and making her inwardly excited as she began to clean the penis.

"Mmm, mmm... mmm, mmm, mmm..."

Ahhh... so dirty... ♡

"Hehehe... That’s good. Keep it up."

She stuffed her mouth full, held the penis between her lips, and sucked. She moved her tongue, licking both the shaft and the scrotum. Chika cleaned the filthy, stinking, smegma‑covered cock with only her mouth. Thanks to the Collar of Obedience, Chika performed her cleaning service without any resistance or hesitation. The man looked down at her, grinning lewdly and nodding with satisfaction.

"Mmm... mmm, mmm... mmm, mmm..."

Ahh... it stinks, it tastes awful, it’s dirty... ♡ This dirty cock is covered in smegma... Ugh, to be forced to suck this cock and clean it with my mouth... Ahh, what humiliation ♡ Ahh, I’m so frustrated ♡ Ahh, I’m getting turned on ♡

While being looked down upon by the man, Chika felt disgust and nausea at the filth and the awful taste of the penis—more intensely than usual—and she felt humiliated at being forced to do this. Yet the more she harboured those feelings, the more excitement welled up inside her.

"Mmm, ahh ♡ Mmm, haa... ♡ Mmm, mmm, mmm, haaa ♡"

Such a... disgusting ♡ stinky ♡ dirty cock ♡ To think I would serve such a dirty cock ♡

She licked it all over and sucked it. The more she cleaned, the more the dirty smegma entered her mouth. Because she kept the penis in her mouth, she could not escape the strong odour. The more she felt it, the more she savoured it. Along with feelings of humiliation and disgust, Chika’s primal instincts as a female were aroused, and she became increasingly excited on her own.

"Mmmmm...! ♡ Mmm, mm, mmm! ♡ Mmm, haaa, mm, mmmmmm! ♡"

Ahh, haaa... um, well... like this, maybe? ♡ Mmm, ahaha... the taste of your dirty cock is spreading throughout my mouth all at once ♡ It’s disgusting ♡

With her excitement continuing to build, Chika stuffed the penis into her mouth, sucking and filling her mouth with it. She performed the cleaning service by sucking with the force of what was commonly known as vacuum fellatio.

"Oh, ohhh...! This one... hehe... that’s good. She’s giving me a pretty erotic cleaning service. Hehe, hehehe."

"Mmm! ♡ Mmm, ahhh! ♡ Mmm, mm, mm, mmmmmm! ♡ Mmm, mm, mmmm! ♡"

This, this is so frustrating, so frustrating ♡

The man smiled and nodded with satisfaction as Chika performed the cleaning service through vacuum fellatio, looking down at her face as she sucked his penis. While being looked down upon with a gaze filled with superiority, even though Chika had started the act of her own free will, she felt humiliated by having to perform vacuum fellatio cleaning. Furthermore, she became aroused by the humiliation, and her excitement grew.

At this rate, it seemed she might masturbate while doing her cleaning service, but before she could do that, the man took a new action.

"Haaah... This one’s no joke. At first I thought I’d let her clean it first and then take my time with her later... but I’m going to let it out now. Heheheh... Here we go, here we go...!"

"Mmmhh ♡ Mmm, mmm! ♡ Mmmhh, mmmhhh! ♡"

Ah, ahhh...!? ♡ Oh, the dirty cock is ejaculating, it’s coming...!? ♡ The filthy semen is pouring into my mouth all at once... ♡

The man ejaculated from his penis. Perhaps because his penis was in such a filthy state, the semen he released was even more viscous and foul‑smelling than the semen of the men who usually raped Chika and ejaculated inside her. Chika felt nauseous and sick, as if her heightened excitement had been dampened.

"Mmm, mmmmm!? ♡ Mmm, mmm, mmm, mmmmmmm... ♡"

That’s awful... semen... ♡ It stinks... ♡ My mouth is sticky and I feel nauseous... It’s disgusting ♡ This, this is just... ♡

However, that nausea and sickness quickly turned into a new kind of excitement. Chika was inwardly melting with excitement and writhing in agony.

"Phew... hehe, that was good. Your cleaning blowjob. Hehe, hehe... Now, make sure you clean up all the semen stains too, okay? With the naughty service you just gave me."

"Mmm, mmm... ♡ Mmm, mmm... ♡ Mmm, mmm! ♡ Mmmmm, mmm, mmmmmmm! ♡"

After he had finished spurting out a copious amount of filthy semen, the man gave the order with a lewd, smirking grin. Chika trembled at those words and performed vacuum fellatio again, cleaning his penis. By the time Chika let go, the penis, which had been in a dirty state, was now somewhat clean, although still covered in saliva. And even then, his penis remained erect, in a state that made it hard to believe he had just ejaculated.

"Heheheheh... That’s good. Thanks to you, it’s getting pretty clean. Heheheh."

"Mmm, ahh ♡ Haaah, mm, ahh ♡ Haaah, ahh ♡"

Looking down at his penis, now covered in Chika’s saliva, the man nodded with satisfaction, then opened his mouth again.

"Alright, now it’s time to stop just cleaning with your mouth and start using those huge breasts of yours to give me some real service."

"Mmm, ahh ♡ Mmm, ahh ♡ Mmm... ah, mm, yes... ♡ Mmm, mm... ♡"

Upon hearing those words, Chika stopped her cleaning service for a moment and let go of his mouth. She unbuttoned her blazer and blouse one by one, revealing her enormous breasts encased in a bra. Then, with her bra still on, she gently lifted her breasts with both hands and squeezed them tightly around the man’s erect penis.

"Mmm, mmmhhh... ♡ Mmm, uh... fuuu, mmmhhh... ♡ Mmm, haa, mmmhh, haaaa... ♡ Mmm, mmmhh, aaa, mmmhaaa... ♡"

Oh, dirty cock... Ah, the heat and sensation of your cock, covered in my saliva, is reaching my breasts... ♡ My breasts are being invaded from the inside by your cock... ♡

As she squeezed and moved her massive breasts around the penis—which was covered in her own saliva—Chika felt a thrill of excitement from the sensation of the penis.

"Ahhh... Your big boobs feel so good... Hehe, hehehe..."

"Mmm, haa ♡ Ahh, mm, mmhaaa... ♡ Ahaa, ahfuu ♡ Mmm, mm, mmhaaa ♡"

As Chika performed a titjob on him, the man nodded in satisfaction, surrendering himself to her service. Chika looked up at him, her excitement building as she continued to serve. Then the man’s penis began to tremble.

"Phew... hehe, maybe it’s because I’ve already come once. I’m about to come again... here we go! Take it in your mouth again... good! Now make sure you catch it all in your mouth!"

"Ah, hah, mmm... ♡ Ah, ah... ♡ Hyaaa, ah, mm, mmm, mmm...! ♡"

Ahhh...! ♡ Yes, just as I thought... dirty semen has come again...! ♡

Chika felt the tremor immediately. The man ordered her to suck his penis, and as she continued the titjob, she took the tip of his penis into her mouth... and then he ejaculated again. The penis had been somewhat cleaned, but the semen that was released again was still sticky and had a strong, fishy smell, which made Chika feel disgusted.

"Hehehe... Make sure you swallow it all down."

"Mmm, mmm... ♡ Mmm, mmm, mmmhhh... ♡"

Ahh... to be forced to drink such dirty semen... ♡ Ahh, ahh, it’s so frustrating... ♡

Not only was she asked to take the filthy semen into her mouth, but she was also asked to swallow it, and Chika felt disgusted and nauseous. Yet this situation made her even more excited.

"Heheh... Not yet. I’m not going to let it end here. I’m going to unleash all the pent‑up energy I’ve been holding in lately. I’ll be keeping you company until the very end. Hehe, hehehe."

"Mmm... ah, ah... y-yes, yes... ♡"

Ahhh... ♡ Ahhhh... ♡

Chika continued to get excited. The man said this to her, holding his still‑erect penis even after ejaculating twice. Those words sent shivers down Chika’s spine, making her feel incredibly excited.
