Lustrous

These alien fungi are good for various refreshment tea. But they also have a habit of ensnaring another organism and borrowing their intelligence to do what makes them feel good. Most creatures prefer to break free from these fungi when they're trapped for intimidation reasons, which then the fungi let them go free. For some creatures who learned the benefits of these fungi use them as nourishment. But for their tea maker, other than giving her the tea ingredients, she also got to fulfil her sexual fantasy.
It started when she was caught by them, knowing that that was normal and they'd only do what she wanted and realized she actually enjoys being dominated by tentacles. She didn't need to masturbate in a bathtub that she filled with her tentacle toys and pretended that she was trapped by them anymore. She had her own sex dungeon where the fungi cocooned her with its inside full of alien tentacles that made sure she was feeling what she wanted.
The trap they built for her was inescapable with any of her various physical attempts. And letting them cover her naked body with their naughty tentacles teased her with how vulnerable she was to them. This delicate helplessness gave her the sense of arousal from anticipating what they were about to do to her, quickened the orgasms that she wanted them to torture her with. And once the thrill began, they bathe her with it as long as she wanted where she lasted a few minutes to a few hours.
The fungi's ability to borrow their company's intelligence made them feel and think the same that she did. It was like masturbating with extra hands. Or, tentacles, in her case. So instead of her "me time", she'd always come back, settling for another cup of her favorite tea.
