How would I reduce the movement of this part when it reaches the location?

(rpet is a brick in workspace) (base is a part that is welded to the character)

My issue is once it reaches the location it moves too much heres a gif of it:

what I need is for it to move a bit but not that much how would I do that?

function MoveBook(pet, mode)
    local character = game.Players.LocalPlayer.Character
    local rpet = workspace["Book1"]
    local rmode = mode
    local inc = .7



if mode == true then -- if this is true then make book float



local base = character[id.."A"]
local dir = CFrame.new(rpet.Position, base.Position).lookVector
print(dir)

for i = 0,10,2 do
    rpet.CFrame = rpet.CFrame + (dir * inc)
    wait(0.05)
end
else
local base = character["Left Leg"]
local dir = CFrame.new(rpet.Position, base.Position).lookVector
print(dir)
for i = 0,5,1 do
    rpet.CFrame = rpet.CFrame + (dir * inc)
    wait(0.05)
end 
    end

end








while wait() do

    MoveBook("Book1", true)
end
