This shit (motherly series by nishi iori) might have became one of my favorite series and I didn't even know it existed because of annoying official publishers memoryholing their shit if you only browse places like sadpanda. Who knew they did a few actual momcest manga that are hidden in the back of their catalogues. Well I didn't.

Group of slutty moms showing their sex drives and tiptoeing the line for 2 chapters until they finally give in, and really well drawn hesitant but lustful expressions from the moms as they start to get closer to the actual incest. One of the first things one of the sons requests is just ball licking into a rimjob rather than the usual which I was surprised I love so much, I guess it feels kind of degrading in a kind of "if you want it so much, here, have it" type of moment.
