The first time I met her sister, she was a cute J-system girl with big breasts. Unable to resist the unconscious temptation of her unguarded school uniform panty flash, I couldn't help but get an erection. My pent-up sexual desire and semen found their target in her panties! I made her wear the panties soaked in semen, promising only that she would dress up like this, and then had her do a panty sock. The freshly ejaculated semen and her sister's love juices mixed together, becoming all slippery and squishy! Unable to hold back any longer, I pulled aside her panties and thrust in raw! Her body arched backward, shaking her big breasts as she reached orgasm. Aroused by her, I couldn't stop pistoning and ended up releasing inside her multiple times.
