My sister went out without a bra and got soaked in a sudden downpour when she came home! I was captivated by her erect nipples under her uniform, and while she was still wet, I squeezed them hard! I had sex with her without a condom, ejaculating into her soaking wet vagina; I couldn't tell if it was rainwater or her vaginal fluid. She had multiple orgasms! SCOP-906
