A very hot self-pleasant luxury sensual spa-like resort time enjoying himself in a lovely water therapy session doing both active physical exercise in nature - as an otter he is enjoying water swimming a lot - and/or cleaning himself in a soothing bathinng after it, enjoying himself on the mirror or on the water forming image how epic magnificent his physique has became and well having some hot pleasant activity of the life growing within him!

That he has a surprise birth, let's say: he is watching something like television on the sofa when out of nowhere he feels the sensations of labor (he clearly thinks it is a false birth), so he does not give it importance, out of nowhere, he feels like a great contraction, therefore, he decides to give a big push, which causes his water to break (feeling a sense of peace) from there, it just pushes without realizing it, making the baby's head pop out very... Slow (he feels amazing) So let it happen until later in the morning, he hears a baby crying (he gave me the idea that he had a normal pregnancy of 9 months, he possibly wanted to postpone the delivery, but seeing that the situation could not be done, he simply grabbed the baby in his bras until later in the morning, he hears a baby crying (he gave me the idea that he had a normal pregnancy of 9 months, he possibly wanted to postpone the birth, but seeing that the situation could not be done, he simply grabbed the baby in his arms, They looked for a sheet, And the 2 of them fell asleep again (something exciting and cute at the same time), it can easily be a single drawing of him in childbirth , or a story, or a comic even, that's my idea
