Teaching incorrect sex education to an innocent but extremely lewd-bodied younger sister led to her curiously touching my cock and asking, "Can I put this inside?" Completely unaware of incest, she doesn't even realize she's being fucked bareback and filled with creampie. As a result, I pound into her with deep pile-driving thrusts, continuously shooting creampies in non-stop cowgirl position. She remains oblivious, even shouting, "You already came inside me!" while losing control. With stiff joints and struggling during stretching exercises, I take advantage of her ignorance to massage her in wide M-shaped legs. Telling her, "This is a highly effective massage even pro athletes use," I slide her panties aside and tease right up to her labia majora. She reacts confused, moaning, "Hmm... something feels weird!" When I insert fingers for deep tissue pelvic massage, she jerks violently from the squishy, intense handjob. Hesitant at first toward my hard cock, she starts stroking it. I expose her massive I-cup tits and shoot my cum deep into her obedient mouth as she sucks me hard. "Can I... put this inside?" she asks. Responding to her request—"Lick while fingering me... do more"—she lifts her hips into a shrimp curve. "Onii-chan, wow! It's amazing, it really works!" she cries out. "You're still covered! Gotta pull it back!" she pleads. While jerking me off, she gives a vacuum blowjob, and I tempt her: "You want this, right? A titty fuck?" Her huge, full breasts engulf my cock. "Go slow! Wow, amazing!" she gasps. My cock penetrates her soft, plump pussy, and she exclaims, "Whoa! It hits so deep! Ah, no—shoko... yes, right there!" Grinding her hips tightly, she rides me with pounding up-and-down grinds, her massive tits bouncing wildly. "What's that look? Is it crazy? So warm! Onii-chan is incredible!" she marvels. In relentless, non-withdrawal pile-driving cowgirl, I drain creampie after creampie, sperm overflowing from our joined bodies.
