The job of my girlfriend's sister, whom I met for the first time, is an esthetician. While she was out, I decided to give her a treatment at home. After enjoying the pleasant sensation for a while, I thought, "Hmm...?" "What? My sister's pussy is touching the tip of my dick...?" "Is this on purpose?!" She pressed her pussy against my erect dick through my paper pants and seduced me! I was teased by her inserting my glans 2cm deep, and she made me cum over and over again until I was on the verge of exploding...! It's the best!
