Not physically...

After Emiru bids you goodnight, you decide to return to your own room. The guest room where you left your luggage is furnished minimally with a Tatami mat, a low table, a Japanese potted plant in the corner, and a futon for you to sleep on. It lacked the personal touch that you'd usually add to a room, especially your anime merch, but the simple but efficient design of the space provided a nice feeling of zen-like calmness.

Despite being told by Mrs. Fukada to go to bed early, you don't feel particularly drained or tired right now; instead, your mind is in a weird, semi-awake place of focus. It's like your jet-lag mixed in with your post-nut clarity. Taking advantage before your fatigue catches up again, you begin to replay the events of the past few hours over in your head, focusing especially on a certain two word phrase.

'Yellow Fever'. What the hell was it? Mrs. Fukada said something about alleviating it, like it was a disease or something, and Emiru had met you in the bath to help as well. They couldn't mean the actual Yellow Fever, could they? You doubted it, given the fact you hadn't traveled much out of your home town before now, and the risk of contracting it from a visitor was minimal. But even if the Yellow Fever they mentioned was something different, how did making you cum fit into the equation? You could certainly ask them, but you were afraid that your level of japanese understanding would prevent you from understanding the answer. Could you search it up? Part of you felt searching "Yellow Fever where Japanese women help you cum" wouldn't get you anywhere either (though it sounded like a sweet Light Novel title).
In the end, you find no answers to your myriad questions before fatigue kicks you in the teeth. After the craziness of the night, you finally flop onto your futon and fall asleep soon after.

You dream that night.

You dream about both Mrs. Fukada and Emiru kneeling on your futon next to you. Both of them are completely naked, their tits standing completely uncovered for your enjoyment. With Mrs. Fukada looking so youthful, you could almost trick yourself into thinking you were looking at two sisters, rather than a mother and her daughter.

You imagine squeezing Mrs. Fukada's big tits, so soft and pillow-like, all the while, she beams at you with a motherly look of caring. You imagine fondling Emiru's breasts, caressing the small mounds she has. All the while, she looks away from you with an embarrassed blush.

After you have your fun, you lean back, and watch as the two Fukadas give you big smiles, before crawling slowly towards you.

"Please, let us help you." They say in unison. You're so hard, you don't even question how you're able to understand them.

You let Mrs. Fukada kiss you. It feels soft and warm and comforting. Meanwhile, Emiru plants kisses along your chest, down to your groin, before beginning to softly kiss your testicles.

You dream that they switch places. You imagine Mrs. Fukada lower herself onto your hard cock, taking it without any pain or resistance. Meanwhile, Emiru leans across your chest to kiss you, her lips feeling moist and loving.

Mrs. Fukada starts to bounce up and down on your dick. Her pace quickens, her massive jugs jiggling and smacking against her sternum.

"Ooh! Yes! Yes, Ken! Cum! Cum in me!" You see her lean in close to your ear and whisper the worst thing she could. "You know you want to."

Fuck.

The sensation of your pulsing dick wakes you from your slumber. The first thing you realise as your senses return is that your pants are soiled around the groinal area from your wet dream.

With a slight feeling of shame, you change into your spare pair of pajamas and sneak into the laundry room to throw your current one into the pile of dirty clothes.

"Three times in one night, huh?" You murmur to yourself with slight amusement, before finally throwing yourself onto your futon and promptly falling back asleep.
