ワンピースの水着とレギンスを着た義理の妹に捕まったところ、足コキで終わりました

Caught by step sister while wearing one of her one piece swimsuits and leggings. At first she was unsure but started to get turned on looking at my hard dick under her swimsuit. It didn't help seeing her feet in pantyhose. It all ended in a footjob I will never forget.
