[KakiPeanuts] Brothers

The runt little brother suddenly sprouts upward and outward into a towering, voluptuous beauty, flipping the sibling size gap on its head while her flustered big brother can only stammer in disbelief. Now saddled with heavy breasts, a soft plump belly, and wide hips, she trades height insults with him until she spots the telltale throb in his pants and happily claims his arousal as her own problem to handle. What follows is a sweat-slicked, smothering session where her massive soft frame swallows him whole, his face pinned beneath her belly and thighs until he spurts helplessly under her weight.
