A girl I've known since childhood straddled me and inserted just 0.1 cm, stopping in an air chair state! She kept her thighs trembling while maintaining the tease. Why did it come to this? Since we were little, she had a tomboyish and lively personality. On the other hand, I was still a virgin, cautious even about having sex with her. This girl teased me, 'You still don't have a girlfriend?' and then provocatively asked, 'Want to practice with me?' At first, I thought, 'Don't mess around!' But somehow, we ended up having sex. However, when it came down to insertion, doubt crept into my heart, and I said, 'Wait a second!' and paused. But the girl straddled me, maintaining the air chair state with her thighs trembling. Finally, I couldn't hold back any longer and thrust in!
