[Hoshino Darts] Mama no Ichiban Kowai Mono (Mama Milk Bokujou) [MrBubbles]

A curvy mother with enormous breasts wakes her young son Kei and immediately discovers the sticky evidence of a naughty dream, and her teasing interrogation about which girl caused it quickly turns into her ordering him to show her exactly how he touches himself. Flustered but obedient, Kei strokes it under her watchful eye while she teases his technique, until his courage finally cracks and he blurts out that he wants to have sex with her, coaxing a resigned smile from his well-endowed mom as she spreads herself and tells him to ask properly. Just as things heat up, a cockroach sends the household into screaming chaos, and the morning ends with a sheepish offer to sleep together that leaves mom completely speechless.
