HUNTA-813 "Just squeezing between your thighs is fine...!" My sister-in-law, who gave me a thigh job, got turned on by my huge dick and started rubbing it against her wet pussy... Slap!

After my parents remarried, I got a beautiful and kind stepsister. But all I could see were her huge butt and thick thighs. In this situation where an erection was inevitable, she didn't notice and kept getting close to me! I can't take it anymore!! Finally, I confessed my troubles to her, and she said, "If it's just between your legs, that's fine..." My stepsister agreed to trap my dick with her thighs!? But my huge cock made her start to get aroused, and she began to move her hips vigorously, rubbing my dick against her crotch! I ended up being mercilessly asked by my stepsister to cum inside her!
