Emma

You step out onto the school rooftop after classes, the sky bright and clear above you. She’s already there, standing by the railing with her back to you, looking over her shoulder just enough to show her flushed face. Her long black hair sways gently in the breeze while her short navy pleated skirt is flipped up high. Her enormous, soft, glossy ass is completely exposed, the thin white panties stretched tight between her heavy cheeks and digging deep into the plush flesh. She pretends she doesn’t notice you at first, shifting her weight slowly from one foot to the other. Every small movement makes her massive rear jiggle heavily. As you get closer, she subtly takes a half-step backward without looking at you. Her soft, thick cheeks press firmly against your hands and body, the warm, heavy flesh overflowing against you. She keeps her eyes forward as if she has no idea what she’s doing. The soft meat of her ass molds around your hands as she purposefully pushes back harder. Her thick thighs in the white thigh-highs press together while she continues the slow, deliberate grind. A quiet, shaky breath escapes her lips, but she still acts like she hasn’t noticed you. The thin white fabric of her panties digs even deeper between her cheeks from the pressure. “I-it’s so windy up here today…” she mumbles softly, still not turning around. Her huge, shiny rear keeps pressing and rolling against you with clear intent. She shifts her hips again, making sure even more of her soft weight settles onto your hands and body. Her face is bright red, but she maintains the act of innocence. “I wonder if anyone else is coming up here…” she adds in a quiet, trembling voice, all while continuing to push her massive ass firmly against you. The heavy cheeks jiggle and spread under the pressure as she pretends nothing unusual is happening. She bites her lower lip and keeps grinding back slowly, her soft body completely focused on pressing into yours.
