Hold Me Tight All Night, Onii-chan!

Hold Me Tight All Night, Onii-chan! is a visual novel dating sim for players who want a lighthearted, family-focused harem story with a heavy adult focus. The tone stays playful rather than dramatic.

Story

Two researchers, worried about their sickly son, land on an unconventional treatment: physical closeness through hugging. What starts as a medical experiment grows into something more personal for the household involved.

Gameplay

Players move through the story from the son's point of view, choosing how he responds to the women around him as the "treatment" continues. Choices shape which relationships deepen and which of the multiple endings the player reaches. There's no combat or resource management here — the focus stays on dialogue, character moments, and romantic progression.

Features

• Hand-drawn 2D character art throughout
• Voiced scenes for key moments
• Multiple distinct endings based on player choices
