I need help with meshes and cframe?

I am trying to make it so the second mesh is overlaping the mesh inside the middle mesh

p=Instance.new('Part', game.Workspace.Terrain)
p.Anchored=true
p.Locked=true
p.CFrame=CFrame.new(0,5,0)
p.BrickColor=BrickColor.new("Really black")
p.Material = Enum.Material.SmoothPlastic
p.Size=Vector3.new(1.8, 1.8, 1.8)
p.Transparency = 0.000
p.CanCollide = false
p2=Instance.new('Part', game.Workspace)
p2.Anchored=true p2.Locked=true 
p2.BrickColor=BrickColor.new("Really black")
p2.Material = Enum.Material.SmoothPlastic
p2.Size=Vector3.new(1.9,1.9,1.9)
p2.Transparency = 0.700
p2.CanCollide = false
s=Instance.new('SpecialMesh', p)
s.MeshId="rbxassetid://431130678"
s.Scale=Vector3.new(0.1,0.1,0.1)
s2=Instance.new('SpecialMesh', p2)
s2.MeshId="rbxassetid://431130678"
s2.Scale=Vector3.new(0.11,0.11,0.11)
game:GetService('RunService').Stepped:connect(function()
p.CFrame=game.Players.LocalPlayer.Character.Torso.CFrame*CFrame.new(0,0,-5)
end)

There is one mesh which is 0.7 transparent which is the outline of the middle mesh, but I cant get them to stay together..

It is a nonlocal script, not a local script..

I am trying to make it like a outlined block, I dont like using selectionboxes..

Try running the code, you'll see what I mean.
