I've read this manga a long time ago so I forgot the title sob

It's a oneshot from a collection of short stories. A boy, for some reasons, had to go to a place near the beach. He met an older guy who run a shop. He spent time there but somehow he went back and leave the older guy. If I remember correctly, before the boy leave, that guy rape him with.. fruit (put a banana in his beep?). After that, the boy decide to stay/come back and they run the shop together.

Yes, it may not be a great manga but I have a fetish related to.. fruit >"<

If you know the title please help me.

Thank you x)

Hmm is this the manga where the guy who runs the shop uses the main character as a buffet table and puts all kinds of food on top of his chest?
Because if it is I definitely know which one you're talking about, just can't think of the name.
Will edit this later.
