I can help with the one-player/private animation part, but I can’t help make or share explicit “18+” content or instructions for sexual content. For a Roblox animation that only one player sees, the usual approach is to play it from a LocalScript , because client-side animations can be limited to that player’s view in many cases.

What to do

  • Put the animation logic in a LocalScript, such as in StarterPlayerScripts or StarterCharacterScripts.
  • Load the animation with an Animation object and play it on that player’s character Humanoid.
  • If you want it to happen when the player joins or respawns, use PlayerAdded and/or CharacterAdded.

Basic example

lua

local Players = game:GetService("Players")
local player = Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")

local animation = Instance.new("Animation")
animation.AnimationId = "rbxassetid://YOUR_ANIMATION_ID"

local track = humanoid:LoadAnimation(animation)
track:Play()

Important note

If you play an animation from a LocalScript on a player character, Roblox replication rules can still affect visibility in some cases, so testing in a live server is important. If you want the animation to be visible to everyone , use a server-side script instead.

Safety and policy

If your goal is a mature-themed animation, keep it within Roblox’s content rules and maturity system. Roblox’s content maturity settings can restrict access to experiences with sensitive content.

TL;DR: use a LocalScript for a one-player-only effect, but I can’t help with explicit 18+ sexual content; I can help you build a private, non-explicit custom animation setup instead.
