After a while, Chinatsu's mother lies down on the bed, spreading her legs wide to make it easier for you and her father to continue their lesson. Her hands move to rest on her head, fingers tangled in her hair as she arches her back off the mattress, seeking more contact with each of you.

Chinatsu watches them intently, unsure what emotions she should be feeling or how she's supposed to react to this surreal situation.

Her father begins instructing Chinatsu on various techniques and positions, explaining how to use her mouth, tongue, and hands to give pleasure to a man. He demonstrates each point himself, showing Chinatsu exactly what he means, while you continue to make love to her mother.

Chinatsu listens intently, taking mental notes as she learns from her father. She can't believe she's in such a situation, but part of her is actually excited to explore these new feelings and experiences. When the lesson is over, Chinatsu feels a newfound confidence in herself and her abilities.
