【sea bird】The story of my sexy brother and sister-in-law and their begging sex

While my brother was away on an extended business trip.
I’ve been living with his wife, Marie, for a while now.

The main character, Takashi, was once in love with Marie.
In the end, the love was unrequited and unfulfilled, and Marie married her brother.

It seemed like their life together was going to be peaceful and uneventful.
Then one day…

(Oh, come on! You’re kidding!)

What Takashi witnessed was Marie masturbating.
Takashi pretended he didn’t see it, but he did.

I’d start masturbating every night thinking about that image.

[ugh, I didn’t expect Takashi to be masturbating with me as a wanker]
Takashi loses his virginity to Marie after she sees him masturbating.

From that day on, they were both addicted to sex…
