This sexy femboy teases with his insane bubble butt, all pure fat crammed into a lean 130-pound frame. Curly afro hair peeks from under a tight black top hugging his slim torso, pale arms reaching back as he arches that lower back. Black thong disappears between those enormous, glossy brown cheeks, so round and heavy they jiggle with every shift. Side views pop that ass out like twin planets, smooth skin glowing under room light, no blemish on that perfect shelf. Pink fabric drapes teasingly nearby, maybe for later play. He's got that feminine curve from narrow waist flaring to hip-hugging width, thighs thick but toned leading to those monster glutes. No cock or frontals shown, just pure ass worship fuel for gooners stroking hard. He questions how much weight to gain to balloon this literal fat ass even bigger, making it clap louder, wobble wilder, perfect for edging sessions. Imagine feeding him calories till those cheeks overflow thongs, swallowing his slim build into pure booty beast mode. Amateur realness, no fake implants, just natural femboy fattie begging for growth. Stroke to the way it protrudes, pregnant-level roundness on such a petite body, side profiles screaming 'spank me, bury your face'. Goon out to this hypnotic jiggle, decide his gain goal and pump your load fantasizing his ass doubling in size.
