Something had been on Satoshi Tainaka's mind for awhile now. He got tired of keeping quiet and eventually decided to talk to his older sister about it. He walked over to her room and knocked on the door, hoping for a response.

"Come in." his sister said.

Satoshi opened the door and walked into her bedroom where he saw she was still wearing her school uniform.

"What?" she said.

"I uh…" he said.

"Spit it out." demanded Ritsu.

"I was wondering… if you could… do something for me?" answered Satoshi.

"Like what?" asked Ritsu, "Do you need your older sister to protect you?"

"N-no. I-it's not like that." answered Satoshi.

"Then what do you need?" the brown-haired girl asked.

"Please… Sis, I want you to eat me!"

"Uh… what?" responded Ritsu.

"I want you to eat me."

"...That's what I thought you said..."

"...Uh… You know what, I'm sorry I-"

"I'll do it. I'll eat you."

"You really will?"

"Of course. Since you want it so badly."

"Heh."

Ritsu took off her shirt, exposing her light brown bra and then slid her skirt down to the floor, revealing her light brown panties. Satoshi looked at her, unsure of what to say. Before he knew it, his older sister was lifting his shirt off and threw it to the floor. Then she unzipped his pants, leaving him in his underwear resulting in a blush in response.

"It's time for dinner." Ritsu said, licking her lips and before opening her mouth.

His sister's mouth opened really wide so that she could take in his head. She slowly sucked it into her mouth and started bringing his face toward her throat. Her brother made no movements as she continued working on swallowing him whole. His head started to slide down her throat and his chest began sliding past her tongue. His stomach entered his mouth next, and then she brought his hips in and kept going.

Ritsu moved her hands over to Satoshi's legs and started to shove them in, getting her past his underwear. Some more swallows get her further down his legs and approaching his knees. She felt her belly expand to make room for her brother and he was really filling her up. Ritsu didn't stop. She took his knees into her mouth and then slurped up the rest of his legs until his toes curled up behind her lips and she finished him off. He completely landed in her acid filled stomach, ready for whatever it was going to do to him.

"Thanks for the dinner." said Ritsu.

"N-no problem, Sis." he said in response.

"I guess this is the part where I digest you."

"Yeah." responded Satoshi.

Ritsu put her hands on her belly and started rubbing. The walls of her stomach started to squeeze him and he began feeling a little bit softer. As she rubbed, Satoshi could feel the movements of his sister's hands which resulted in him feeling much more comfortable. He didn't even move. He just relaxed and let her belly have its way with him. His body was slowly broken down, piece by piece, flesh coming off his body and pooling around him.

"How ya feeling?" asked Ritsu.

"It feels great!" responded Satoshi.

"Glad you like it." said Ritsu.

The stomach acid started working a bit faster. The walls of her stomach started moving at a quicker speed as well. Satoshi's body was tossed all over his sister's belly, acids continuing to splash over him, soaking into his skin. More of his flesh was melting off of his bones and he was greatly enjoying the feeling of getting digested by his sister. Before he knew it, he couldn't move and was soon submerged by her stomach acid. Ritsu noticed how much smaller her belly had gotten, so she gave it a poke.

"How are you now?" she asked.

The only thing she got in response was gurgles.

"Good boy." she said.

Satoshi hadn't lost consciousness yet, but he was getting close. He just smiled, happy that he was such a great dinner for his sister and then it faded. He was completely unrecognizable by this point. Just a mess of flesh and bones, floating around in his sister's gut. Ritsu's belly was way smaller than it was when she first swallowed him. Ritsu soon relaxed and watched her belly shrink some more until it was almost flat. She had gained a bit of fat from digesting her brother, but she was happy he made such a good dinner.

"You were the best dinner I've ever had." said Ritsu.
