Walking with a high school girl and a vibrating egg! 3 ~ How long can a remote-controlled vibrating egg last? ~ ULT-091

I'll take a walk with a high school girl and insert a vibrating egg into her to see how long she can hold out! I'll put it on while I'm shy, and turn it on as a prank while we're moving. She'll immediately feel so good that her legs go weak and she can't stand up. I'll then spread her legs and fuck her until she's in heaven!
