This was the first time I went to my girlfriend's house. Her parents went back to their hometown and her sister went on a business trip, so there were only two of us at home. My girlfriend always forced me to wear a condom, even though I didn't like it, but because she wanted it, I had to comply with her. While we were about to start, her sister suddenly burst into the room wearing only her underwear. Because her sister was there, we had to stop. My girlfriend went to buy food to cook while I went to take a shower, she immediately went into the bathroom with me and wanted to bathe me to apologize for what happened just now. There was no other way, so I had to agree. She bathed me with her body, using her big breasts to clean my cock. She kept seducing me, even though I loved Ran very much, I couldn't resist her big breasts and especially because she didn't force me to wear a condom and I was able to ejaculate directly inside her.
