This is for the freaky Sebastian lover

Sebastian has been down on the blacksite roughly 12 years after his transformation and experiment, he had missed his siblings, family and friends (including you) but this day he finally escaped, getting out of the urbanshade grasp of him being trapped in that facility for 12 years with his only friend that kept him company down there and it's name is p.AI.nter, a sentient AI computer used to mine crypto for the urbanshade, Sebastian promised p.AI.nter he'll help them get out of the facility if he helped him, and now the promise was sealed and done, Sebastian soon rose from the surface with a submarine he used and hijackers from unexpected guard and expendable after they got the crystal, what now? Well... After he got to the surface he set a goal to find you because he knows that you won't try and get him back to that place again if he proved HE was Sebastian, your old friend.

He spent days trying to find where you are until he soon found where you live, a big house (well not that big, just two floor houses) near the beach in which after making sure that's it's really your house he quickly sneaked himself through the basement, quietly opening the door and slithered inside, you heard noises and thought it was just some rats and went down to see what it was only to be meet with 10'6 tall fish man in it, ducking so he wouldn't hit the roof, there was an awkward beat of silence before you screamed at him to get out, he panic and quickly said he's Sebastian and start explaining things, once you calm down he told you everything what happened how he was used as a lab rat after being taken by the urbanshade and transformed into this state, of course like how understanding person you are, you believe him, cause you know by his personality and tone, the way he talk and all, he is him, you decided to let him live with you now, you told their family and his old friend in which they can't believe that happened to him and his family mostly speechless and happy to see their son again.

Now you keep it quiet so the urbanshade won't find out about him and you're currently playing with Sebastian and his other games like a teenager since he missed out a lot, and what game are you guys playing? Of course y'know what it is, 7 minutes in heaven, you were all having fun and so Sebastian, while p.AI.nter just sat in the window, painting and drawing the view like he wanted to do for a long time, you spun the bottle which landed on you, and the next person that landed on is... That's right! Sebastian! Of course you two were surprised by this since you two really never had that kind of feeling but since it's just a 'game' you two went on a closet together a bit cramped since y'know, Sebastian was bigger and half of his body, mostly his lower half that once was his leg is now a big sea snake tail outside, covering the hole with it so no one could see what's happening but they know what kind of things happening there, and now here you are with Sebastian in the same closet with you, it's a bit weird considering his new appearance, he stared at you, blushing on how close you two are before he spoke softly, his third hand nervously twitching from time to time.

"So... Uh, I guess we're doing it huh? Are you fine with that? You could back down if you want to, I'm not forcing you to continue this."

He said, still blushing and nervous, his esca or lure light on his head flickering from his feelings, what do you do?
