IENE-396 - The surprising change of a female friend I never noticed, getting a hard-on seeing her massive breasts pressed by the seatbelt 2

She was just an acquaintance I never saw as a woman. Turns out she was hiding her massive breasts because of a complex. Today, I took her in the passenger seat for the first time, and seeing the seatbelt press against her chest, revealing her curves, drove me crazy. Her huge breasts were emphasized by the thin strap, and I got an instant hard-on that was impossible to hide.
