Kushina had a few idea's on how to decide which girl would be best for her son to start a relation with. She was secretly planing to swallow the one she found lacking so Naruto wouldn't be able to pine for the one she felt was wrong for him. As you can see in the next picture things didn't go quite as planned and Kushina was rather hungery explaining part 3 Hungery Kushina. The other two were basicly what-if the other girl was quicker.
I've thought about doing just that sadly though I'm not to good at writing vore stories. But should inspiration hit me then I most currently will write something for this. In the mean time anyone who wants to try is welcome to as reading them may in turn give me an idea or two on how to better make a story of it.
