"Haaaaah ......"

He looks down at the thick bandages wrapped around his arms. The doctor said it wasn't a serious injury, but still, an injury is an injury. His girlfriend "Chisa" is also traveling with her friends. It was summer vacation, but I had no choice but to stay at home and be quiet.

Then one day...

"Yoo-hoo, long time no see!" "Hinami-san ......?"

Hinami is Chisa's older sister. She's so famous that even in the school there's no one who doesn't know her and she's the object of everyone's admiration.

Why are you here? The reason for this is that Chisa, who has been taking care of him up until now, is going to take over for her during her trip.

"It's my dear sister's request, of course she'll be happy to come."

Hinami-san carefully wipes his body. The soft scent of cologne wafting close by and the somewhat lickety-split hand tracing the body ...... and naturally the crotch...

"Oh, ......, well, you're a boy and if it's been a while, you've got a lot on your plate." "No, well, she usually does a lot for me."

Hinami's hand, which was wiping his body, stopped and she went downstairs. She kept her hand on the zipper of his pants.

"That girl who does so much for you, she's gone now, isn't she?" "So ...... I'll do it for you." "I've taken on the responsibility of taking care of you, so I should be responsible for these things, right?" "I can't betray Chisa ......." "It's okay, it's okay, it's not cheating as long as you don't put it in there, okay, I'll take care of it?"
