"Sweety, Miranda and Jessica are staying over for the weekend. When they arrive, can you please help them with their baggage?"
Aunt Miranda is a big, very big, woman. She has red hair and is more than 6ft tall, but, what calls more attention to her is her weight, she is at least 350libs, distributed through her thick legs, large breasts and big belly. Arthur always liked her, despite her being a little bit clingy.
Jessica, his cousin, is pretty much like her mother, just a little bit smaller in weight size, but still with a very chubby figure, and her red hair is a little lighter. She is one year younger than the boy but still manages to tower over him and treats him like a child.
"Sure", Arthur said, "When are they..."
The moment he opened his mouth, they heard someone at the door. Laughing with his mom, Arthur calmly opened the door, suddenly feeling his head being forcefully pulled into a hug, his face being buried into a pair of large, milky-skinned, breasts.
"Oh, Arthur! We missed you so much!" Miranda said, her strong arms smothering the boy in her bosom, "Give your favorite auntie a hug, come on!"
"Mom", Jessica said, "I think you are crushing him..."
Without the girl noticing, her own aunt, Arthur's mom, Andrea, appeared at the door and pulled her sister in a hug, while she still was smothering Alex. The boy was buried so deep in the flesh of his aunt's fat belly and large breasts that his mother could barely see him.
"Come here, Miranda", It's so good to see you!" The woman said as they sandwiched her son.
Eventually, when they stopped their reunion moment, Arthur was able to escape the powerful bear hug he was receiving. His face was blue and he was quite dizzy, but at least his ribs didn't crack, what he was pretty sure would happen. For a moment, he thought there was something hard pressing against him when his aunt was crushing his body, but he dismissed it as just his imagination...
"Alright," he said, taking a deep breath, "Let's get your baggage to the guest's room, shall we?"
As he said that, he grabbed his aunt Miranda's heavy luggage and started to climb up the stairs with it. As they were walking up to the rooms, with him in the front, she said, as she discreetly watched his butt moving at every step he took:
"Oh Arthur, you are such a good boy!"
"Thanks, auntie..." he grunted, pulling the heavy, old, bag up.
As they opened the door of the guest's room, both women looked at the bed and gave each other a worried glance.
"What's the matter? You can't share a bed?"
"Well honey, the problem is not sharing a bed, the problem is that we don't think that this bed is gonna be able to support two big girls like us..." His aunt said.
"Yep, we need resistant stuff, little guy," his cousin said, playing with his blonde hair.
As he examined the bed, and his aunt and cousin's big bodies, he presumed they were right. The bed would probably crack the moment the two lay down on it. As he was thinking about a solution, they heard someone:
"Well", his mother said, appearing from down the stairs, "I am pretty sure that, if sharing a bed isn't the problem, then Arthur would have no problem about sharing his own with one of you, right Alex?"
Arthur gulped as he turned his face around and looked at his aunt and cousin's huge size. As he nodded, he was pretty sure that judging by the sudden twitching bulge between their legs, their bellies weren't the only thing big with them...
Skipping to the night, who is sleeping with him?
