If the hero of a novel on pixiv is the defeated end of the story.
【https://www.pixiv.net/novel/show.php?id=19846233】
The heroes were humiliated all over by THE Tentacle's tongue as they were forced to face each other.
The mouth is also filled with THE Tentacle's tongue, and spreading in its place is the sound of lewd water, muffled moans, raucous snorting, and the smell of cock.
The tongue around their dicks moved slowly to encourage them to ejaculate. (That sounds like a masturbator!)
It continues to slowly and pleasantly stimulate the heroes, even as they convulse their bodies and spit out their semen, trying to get them to ejaculate continuously.
The movement, which is never violent, does not reduce their physical strength much.
Instead, they forced to ejaculate much as their strength allows.
This hell of humiliation will continue until the heroes succumb to the stimuli and are defeated....
