We invite an emotional J○, wearing a sweaty uniform and showing her bra, to the studio! We negotiate the plan, saying, "If you can make me cum with a thighjob through my panties, I'll give you a prize!" The horny girl, who just broke her hymen, rubs the tip of a huge dick 3cm into her pussy, and gradually twists her hips, wanting it deeper, distorting her face and reaching her limit of activity! She squirts with joy at her first direct piston-like porcio thrust, and can't refuse the sudden explosion!
