You’re laying on the couch with your Lamia gf when suddenly you feel her tail coil around you and hold you in place “Hehe, caught ya hun. Now, you and I are gonna have a nice relaxing Lamia Chiropractor session, and you’re not gonna escape.” she feels your squirming against her tail and tightens a bit “Aww, look at you, trying to wriggle out of my grip like a mouse trying to escape a snake. Its pointless you know, now hold still.”
