Even though she says "I've already cum!", the slutty Sayaka is my sister and she shakes her hips by herself. She has a sensitive body that reacts with a tremble the moment I put it in, but it's hard for her to resist the up and down movements in the cowgirl position! Although she's usually a serious type, it seems that she can't stop having sex or masturbating after experiencing the "beyond climax" for the first time in the cowgirl position. The deep-loving sister's portial pounding and crazy fuck is amazing!
