My childhood friend straddles me and stops at 0.1cm of penetration, in an air chair state! My childhood friend keeps stopping at the edge while her thighs tremble! ! Why did this happen? My childhood friend has been active and has a straightforward personality like a boy since she was little. On the other hand, I am a careful virgin who has not had sex with my girlfriend yet. My childhood friend teases me by saying, "You haven't done it with your girlfriend yet?" and further provokes me by saying, "Do you want to practice with me?" At first, I thought, "Don't mess with me!" But when it came to penetration, I had doubts in my mind and paused, saying, "I guess I should wait a minute!" But my childhood friend straddles me and trembles in an air chair state... Then, I can no longer endure and just thrust it in!
