I was lying down feeling tired when suddenly my sister kicked me and said, "Let's play wrestling!" Then she jumped on top of me and started using an electric massager on me out of nowhere! I got pissed and fought back with the massager, but she started getting turned on, twitching and eventually climaxing! Haha, it got interesting, so I spread her legs open so she couldn't close them and zapped her with the massager while recording video! She was moaning sexy, begging "Stop it already!" but of course I wasn't going to stop! Haha! While twitching, she said, "I'll do anything you say!" so I pretended to forgive her—only for her to hit me with tickle torture next! Haha! She's always been super ticklish, so her reactions were amazing! I kept tickling her while shocking her with the massager, tormenting her endlessly until all my stress was gone! After getting tired, I made the completely worn-out sister give me a massage, but she seized the chance, rolled me up in a mat like sushi, and immobilized me! Now her revenge begins! She used the electric massager on me until I ejaculated, and even endured a double attack of electric massager and denma, pathetically climaxing over and over from my little sister's "Shiori"! ※ Facial exposure in main video
