My sister almost dropped her wallet, so I called out to her—only for her to immediately target my cock with a kick. Turns out she does kickboxing, and I'm amazed by her power. I ask if she can try using it on me, and she invites me home. When I tell her, "I usually get rock hard squeezing tits like these," she starts moaning more and more, despite protesting. Her panties grow wetter by the second. In the end, I insist she's no use unless I confirm I've cum inside her—so I finish by shooting my load deep within.
