I don't really think about seeing my younger sister's body like a bra, but one day I was surprised to see her in a sports bra! She made fun of her, saying, "You've become a girl and haven't graduated from Sports Bra yet!", but when I looked closely, it was surprisingly erotic and I couldn't help but get an erection! When my sister noticed this, she suddenly approached her and said, "I was getting an erection while saying something!" What's more, I played with my erect cock, so I couldn't help but ejaculate a lot! ! Then, he puts his dick in his mouth with the face of an adult woman...
