A female friend misses the last train and ends up staying at a man's house. - A man gets excited about a big-breasted woman while sleeping in the river. - The woman seems excited when I secretly touch her breasts, and when she starts making noises, I take her into the futon and make her cum close to me. - The other woman, who was watching the scene from outside the futon, also got horny and crawled under the futon, making for a harem close-up threesome where she was attacked by two big-breasted girls.
