Katrin, her belly round with life, has discovered a new, exhilarating way to pass her time at home. She waits, naked and eager, on the staircase, her body a symphony of curves. Her fingers, slick with her own arousal, trace her pregnant form, pausing to tease her hard nipples and swollen clit. She's left her socks on, the simple fabric a stark contrast to her bare, vulnerable flesh. As she strokes her wet pussy, her mind races with fantasies, her body tensing with each wave of pleasure.
