Misaki Sugisaki DVRT-014 (Assisting with masturbation and generating her own electricity)

Staying temporarily at my brother and sister-in-law's house, I can only repay their kindness by masturbating. Today, I was also masturbating, but unexpectedly, my sister-in-law came to help me generate electricity. Since there are various ways to recharge, today my sister-in-law taught me how to generate electricity through combined penetration. This felt so good. I ejaculated inside.
