彼女の姉とのイケない関係～先っぽまでって約束なのに…～（Kanojo no Ane to no Ikenai Kankei ~Sakippo made tte Yakusoku na no ni...~）

I let out a sigh, looking over the thick bandage on my arm. The doctor told me it wasn’t a big deal, but still for me, an injury nonetheless.
Chisa, my girlfriend, had been away on a trip. I, on the other hand, had to sit still at home with this injury now, wasting away summer holidays.

On one of these days…

“yahoo---! How are you doing!” “Hinami-san!?”

Hinami-san is Chisa’s elder sister. It would be hard to find someone at school who did NOT know her. That’s how much respected she was at school.

“What are you doing here?”

Chisa apparently asked her to come see how I was doing and help out, since she couldn’t, being on a trip and all.

“Like, don’t let it bother you, ok? I’m more than glad to listen to my cute little sister’s request!”

She very gently takes off my clothes, to wipe my body. Her soft mellow hands carefully trace my body, her sweet fragrance wafting near me.
I naturally get an erection.

“Ah! You must have bottled up, being like this for so long.”

“yeah well, I mean, I usually have Chisa take care of it for me.”

Her hand wiping my body stopped, then slowly swept down, and started unzipping me.

“Now she isn't here to ‘take care of it’. let me do it in her place. No, I have to do it. I did accept her request to take care of you, and I have to show it.”

“No I can’t do anything to betray her trust…”

“It’s fine really. It’s not cheating as long as you don’t penetrate.”
