WARNING: contains f/m vore, m/f vore, and digestion, all willing and safe.
 On a world very far away, there lived a fifteen year old girl named May who lived with her mother and her almost thirteen year old brother, Ben. They seemed like any other family, but they had a secret they kept from just about everyone. Their mother, a woman named Val, was born with the ability to contain living beings, even ones larger than her, within her body. An ability that was passed on to both of her children, though May seemed to use it more since Ben liked it in her belly.
 "Come on, sis!" Ben said to his sister one day while she was sitting in her room playing video games. "Can you please eat me?"
 "I already told you, Ben. I can't, today. I'm meeting with my friends at the library later today and I can't have my stomach bulging out without revealing our secret." The teenager explained.
 "Come on." Ben pouted.
 May thought about it for a moment before speaking up. "Okay. I'll do it under one condition."
 "What's that?" The boy asked.
 "I've eaten you countless times, but I've always wondered what it's like in someone's belly." May began. "I'll eat you if you promise to eat me once I let you out."
 "Me? I don't know if I can."
 "I think you can. Mom said that both of us inherited her ability." May answered.
 "Hmmmmmm..." Ben said as he thought about it."Okay."
 "That's great." May grinned as she was about to grab Ben. "Oh. I almost forgot. I'm going to have to digest you this time since I have to meet up with my friends very soon, and a smaller bulge will be easier to explain away. You don't mind, do you?" She asked.
 Ben smiled. "Not at all."
 "Okay." May smiled as she grabbed her brother and engulfed his head in her mouth, licking when she could and enjoying the taste. She then swallowed and started working on his torso, which was a slight challenge to gulp down. After a few more gulps, only the boy's legs were sticking out of her mouth, which she slurped down like noodles. As Ben's feet joined the rest of him in May's stomach, the girl let out a small burp as she rubbed her now bulging stomach. "Now to let my stomach do it's thing. You will keep your promise once I have you reform, right?"
 "Yep. Once I reform, you'll go straight to my belly." The almost teenager giggled.
 "Good boy." May said as her stomach acids got to work on her passenger. She turned off her game and decided to lie down on her bed as she digested Ben. After about an hour, she noticed that her belly was about half the size it was when she ate her brother. "Hmmmm..." she began as she rubbed her belly contently. "It takes me about half an hour to walk to the library from here. If I leave now, I'll be there right on time and Ben'll be mostly digested. It would be good exercise." With that, she packed up some of her books and left her room.
 "Are you going to the library, now?" Val asked her daughter as she approached the door.
 "Yeah, mom." She called. "I'll be back in a bit."
 "Is Ben going with you?" Her mother asked.
 "I just had him for a snack." May said as she opened the door. "Bye." She said as she walked out the door and headed for the library. As she approached the library, she looked down at her stomach and saw that it was mostly flat. "Heh. He didn't take long to digest at all, today." She thought as she patted her belly and saw that there was a little bit of noticeable fat on her belly. "I guess I gained a little fat on my belly. Oh well. It actually looks pretty good on me."
 "I guess that's a benefit of eating me." said Ben in her head.
 "Yeah. You make good belly fat." She giggled.
 Another strange ability of May's family is that if they eat and digest a living being, that being will retain their consciousness within them and can communicate witb them via telepathy. It is an ability both May and Ben like.
 "Really?" Ben asked. "I do?"
 "Yep." She said as she walked into the library and met up with two of her friends, Jane and her adopted sister, Sky. Jane was a short red-haired girl and Sky was a brunette who was pretty tall for her age.
 "Hey, May." Jane said as she noticed May's stomach. "You're getting a little pudgy, girl!" She giggled.
 "Oh." May blushed. "I had a big meal before I came here."
 "Don't be so embarrassed." Sky began. "You still look nice. What did you eat?"
 "Um..." May said as she tried to think of a good answer.
 "I know." Jane said as they sat down at a table. "Her brother's in there, or at least was."
 "Huh?" May asked. "How did you-"
 "How did I know? I've actually suspected it for awhile, especially after last week." The redhead answered.
 "What happened last week?" May asked.
 "According to my little sister, she was taking a walk with Ben when she tripped and her head landed in his open mouth, which caused him to swallow her." Jane explained.
 "Is this true?" May thought.
 "Yeah." Ben said, embarrassed. "It was an accident, but Kristen was delicious."
 "Is she alright?" May asked.
 "Yeah. She said she actually liked it." Sky said.
 "And it does sound interesting." Jane began. "Could we try it with you later?"
 "Not today. Maybe next week, though." May answered.
 "Okay." Both girls said in an excited voice.
 "Come on." May began as she placed some books on the table. "We really should study for those tests."
 They studied for well over an hour before everyone decided it was time to leave.
 "I think we should go, now." Jane began as she whispered in May's ear, "Maybe next week you can leave the books in your belly with Ben?"
 "Will do." May grinned as they walked out of the library. "See ya on Monday." She said as she walked home.
 As she left, a boy who appeared to be about May's age smiled. "How interesting. That girl is truly unique."
 When May got home, she plopped down on her bed and looked at her stomach. "So you've alrewdy used our ability?" She asked.
 "Yeah." Ben began. "When I accidentally ate Kristen, we found that both of us liked it."
 "Are you ready to reform, yet?" May asked. "You still have your end of the deal to keep."
 "Yep." With that, May tapped a few spots on her belly and her brother appeared before her, clothes and all, as her stomach returned to normal.
 "Given the compliments I recieved today, I'm almost tempted to just leave you there next time." May chuckled.
 "Maybe." Ben said as he eyed his sister. "You look filling."
 "I guess I should." May said as she dangled her feet in front of her brother. "Come on. Eat up."
 Before she had finished speaking, Ben engulfed her feet in his mouth and started swallowing while enjoying the taste of his sister. He had an easy time swallowing until he got to her breasts. "This will be interesting." He thought as he started gulping. It took awhile, but after a few hard gulps he had swallowed everything up to her head.
 "I hope you like having me in your belly, Ben." May grinned as Ben swallowed the rest of her and saw that while there was a slight bulge in his stomach, it wasn't nearly as big as May's when she ate him.
 "Interesting. My belly's the same size it was when I ate Kristen. I guess only girls get large bellies." He giggled as he went to his room, which was right next to May's, and watched TV for a few hours. As it was getting late, he heard a yawn coming from within his belly. "Getting sleepy, May?"
 "Yeah." She yawned. "Would you mind if I slept in here for the night?"
 "Not at all." He responded. "Would you mind if I decided to digest you?"
 "Nope. I don't mind. I'll probably be in here the whole night."
 "Okay." Ben said as he took a shower and got ready for bed while his stomach got to work on its meal. "Good night, sis." He said as he got into his bed and fell asleep.
 Later that night, Val walked into Ben's room and saw the slight bulge in her son's belly and a low gurgling sound emerging from it. "So he finally decided to use his gift." She grinned as she knelt next to the bed. "I am so proud of you. I'll see both of you in the morning." She said as she kissed Ben's forehead and patted his belly. "Sleep well, kids." She said as she went to her own room and fell asleep.
 Both Ben and May had one of the best sleeps they ever had.
