With his parents away on a trip, Nami — the girl he grew up next door to, now very much an adult — comes to stay. They were close enough to share a bath as kids, but the Nami standing in front of him is nothing like the one in his memory, and his heart won't settle. Somewhere along the way she got big tits and a body to match, and when he can't help putting his hands on her, she snaps at him. Now the sleepover is awkward. He sulks off to the bath — and she climbs in naked with him. They go all the way. Once it starts they can't stop: all night, and still going when the parents are due home.
