This is the first time I have been to my girlfriend's house. Her parents went to the countryside, and her sister went on a business trip, so it was just the two of us at home. My girlfriend always insists that I wear a condom, even though I don't like it, but because she wants to, I have to comply with her. Just as we were about to get started, her sister burst into the room wearing only lingerie. Because her sister was here, we had to stop. My girlfriend went to buy groceries while I went to take a shower, and her sister followed me into the bathroom and wanted to shower me to apologize for what just happened. There was no way out, so I had to agree. She showered me with her body, using her large breasts to clean my penis. She kept seducing me, even though I love Ran very much, I couldn't resist her big breasts, especially since she didn't make me wear a condom and let me ejaculate inside her directly!!!
