"I'm sorry to make your penis bigger." Since it's so small, it should be okay, right? The nephew, who entered the women-only carriage with his aunt, became completely erect under the influence of her large breasts! His panicked aunt secretly pulled it out for him. (DANDY-987)

I went on a trip with my busty aunt. As we boarded the train… I thought, “It’s okay since I’m just a kid,” and we got into the women-only carriage. The older women boarded, and I was surrounded by so many breasts. Unable to resist, my aunt, noticing my penis had gotten bigger, secretly pulled it out for me! But the erection wouldn’t stop… My aunt did something even more lewd, making the trip truly blissful.
