Ninja Training Continued (Pixiv Fanbox)

The sequel to my "Ninja Endurance Training" pic from earlier this year ^^ Since Naruto was so awful at holding in his spunk at the hands of Konohomaru's stroking technique, the smaller boy decided to utilize a more advanced "ninja training method". Zipped up into a tight rubber bitchsuit, Naruto's rising concerns that this wasn't real training were interrupted by Konohamaru pulling out a dildo machine. The rules are once more the same, except this time Naruto has to not cum purely from the anal stimulation. Konohamaru even tied up the boy's dick in a nice package to make it easier for him! Of course, it's all in vain as Naruto fails to withstand the dildo's relentless thrusts. Now he has to listen to Kono's equally-relentless taunting as the machine's speed rises and more cum spurts out. I imagine after this Naruto will realize he's been tricked, but by then he'll be too trapped by the small master to do much about it. He'll make a much better pet than Ninja though!
