Bob looked back and forth. This had to be the toughest decision he ever had to make. He had experienced being up his wife's ass, and her pussy before, but to choose only one, how could he do that?
After once again looking back at the glistening insides that led to her womb, Bob took another look at his wife's rear. He had always been ass man, and from the moment he first spotted this one way back in the day, he knew he had to have it. Sure he acted all cool and said thngs like "I work alone." like most heroes, but no matter how many powers you have, you still have human needs.
Helen chuckled as she watched him struggle to make s decision.

"Let's go with the ass." Bob just picked at random. Now it just didn't matter, he just wanted some more action.
Helen continued to grin, and parted her cheeks apart once again "Oh poor thing, my butt hasn't gotten any attention yet has it? It needs to be fed.".
Her voice suddenly became lost as she felt her husband's head push up to her rectum. It widened greatly.

With a tough jerk it pulled in the top half of Bob's head. Helen started to scream, he was just so big, but she could take it. Her juices began to drip down on the sheets.
Helen in a sense meant what she said before. From the first time she treated Bob to anal vore, she had gotten a craving for it many times afterwords. Even before then, Helen always had a thing for her big booty. When she just started being Elastigirl, there was nothing big about it, she was about as flat as they came. Then later on, when she found out she could swallow people, Helen noticed something. Everytime she digested somebody, she noticed that she mainly gained in her lower region. Soon she had a nice big bubble butt, and she loved it. Next she started to think that her legs were too skinny, and so were her hips. That quickly changed.

Helen's voice was almost lost as her ass ate up Bob's shoulders, and prepared to move on to his broad chest. Eventually she screamed as she came.
On the inside, Bob didn't do much except squirm. Actually, that was pretty much all he could do. Helen's insides may be flexible, but once something or someone was inside, they held with a tight grip. Probably to insure no escape. Bob chuckled at that thought.
He couldn't see much inside her aside from the pink shade of the walls, but that didn't matter to him. Helen's bowels were also very clean, especially after she took care of what was left Fire Swallower earlier.

After cumming again, Helen groaned as her ass tryed to keep going. At one point she wasn't sure if she could finish. She shook that off, not wanting her rear end to go hungry. Her cheeks flexed as the worked on her husband's midsection. Speaking of which, Helen looked back at her cheeks. How many villains had been sacraficed to these two perfect orbs of fat? Still, Helen did also owe some of it to her 'diet'. Like she mentioned to Fire Swallower, her body could hide any unsightly bulges, so she could pretty much eat anything she wanted. When it came to her large caboose though, there was nothing to hide.

Helen suddenly heard a loud groan from inside her. She soon realized why when she felt Bob's dick start to be pulled in. Her rosebud began to subtly suck in his hips, Helen wanted to make this count. Bob had already experienced to orgasms, and the feeling of the tight, pulsing, hot walls against his member just set him off.
Helen moaned as she felt her bowels being coated with hot seed.
Finally, as her ass once again demanded more, it sucked up his legs. Helen's cheeks slapped together loudly with the final swallow.

Helen collapsed back on the bed. Hormonely drained, the bed wet with cum, and now with a large belly once again, she smiled.
