>>97725710Because Matsuri has made being a sex pest her entire identity and it's THE thing she's known for. All the girls have stories of doing gay shit together anyway, it's not like just Matsuri has got manager approved perms to take any holo's virginity at a whim.
If you're asking why it's okay for her to be slutty in regards to the classic "why can holo do x but other corps can't" then it's simply because people like Hololive more and are willing to turn a blind eye. Humans are hypocritical like that, what are you gonna do.
>>97726971Ollie admitted that she met Matsuri recently and that she frenched her, though whether that counts or not for festival is up for debate since Ollie was apparently so shocked she didn't even reciprocate. Matsuri was using tongue though so make of that what you will
