MUKC-024 - Kidnapped and held hostage, the idol who betrayed me is now a semen-covered toy

Starts like a horror movie with a creepy story about an otaku's revenge. I don't get why he starts by shoving his fingers into her mouth. There's zero eroticism in it, and the guy just smears his saliva-covered fingers all over her face. The beginning is the most important part when you're with a woman, so why start with finger-stuffing?

I see this in other works too, but why shove fingers into the mouth? I don't get it. It doesn't feel good and it's not a turn-on—am I the weird one? Is it an extension of oral sex? It's a huge turn-off and I wish they'd stop. Kissing while thrusting makes sense because it feels good, but I don't get the appeal of hand-stuffing. My wife once tried a handjob with lotion after learning it somewhere, but it felt so bad that when she asked 'How is it?', I had to ask 'Do you even want to do this?'. That was the only time in my life. My partner and I have agreed that for both of us, oral sex, kissing while thrusting, and breast play are the best, so we stick to those.

The 19-year-old girl has an innocent look, pale skin, and adorable clothes. A cock is being churned inside her mouth, making wet, slapping sounds. Her face is covered in fishy semen. A massive desire endlessly ravages her body. With a quick thrust while holding her head, the glans goes straight into her esophagus. When the cock is pulled out of her mouth, she stares into the void with a look of despair. He doesn't spare her vagina either; after cumming inside, the fishy semen flows out, and the scene ends with the cute idol girl rolling her eyes back in a daze.
