[Excruciating pleasure!] In the cowgirl position, the cock is slowly twisted around in the vagina, and the pleasure is so intense that it makes you lose consciousness! "Don't cum on your own," says the older sister, who always takes the lead! Every time you're about to cum with a violent up and down pounding piston, it stops right on the brink. Kokoro and body are controlled, and when you're teased, you can't stop the pre-cum because you want to cum so much! It's all for the ejaculation paradise that awaits you at the end of your patience, so you can feel the liberation ecstasy of a massive ejaculation that makes your mind go blank!
