The promiscuous sister vs. the virgin brother, an unexpected climax endurance match due to a sibling argument!? My always mocking promiscuous sister and I started arguing and ended up wrestling, resulting in her breasts and ass being fully exposed! She teased me with my erection and gave me a handjob, causing me to unintentionally ejaculate... However, not softening at all, I retaliated by inserting my dick! The sex climax battle continued until she surrendered! But the pleasure was overwhelming, and we repeatedly had internal ejaculations and reached climaxes together!
