I disagree, because MT already has several people involved Peter, the hot maid from the toilet with Alice, Aron and David. It's already a mix, so their mom would just add to this awesome collection. Aron didn't just want to have Sarah, he wanted to have her every day! And if it happened once, then why would he give it up? That would look stupid, that both (Aron and Sarah) of them felt great together, and realized that they wanted sex every day!That itself is pretty dumb since MT started out as an Aunt thing opposed to SN and ID, now you got Aaron so the mom fetish is met nonetheless, pulling new family members each time would just make already introduced character less prevailing in story. Example- Peter is already forgotten in the story and has no impact, all it took was for Aaron to get Sarah and Alice with David, extra characters would be bad addition. If you want new milfs it’s better to create new stories
AND then suddenly it disappears. That would be even stupider than introducing David and Alice's mom, whom they had mentioned several times.
Sarah showed David the way of life, opened the wide world, the ocean with "fish"! She did her "job".
If the comic hadn't infiltrated Peter, Aron and the crazy hot woman in the cafe toilet, then I could agree with you, but now this story has been expanded, so it must be continued.
