Because he's a child, my nephew, who went into the women's bathroom with me, got a full erection when he saw her large breasts! DANDY-914

I went on a hot spring trip with my mother and aunt (who has huge breasts)... "Since I'm just a kid, it's okay, right?" My aunt and I decided to go to the women's bath together. Surrounded by large breasts in the women's bath, I couldn't help but get an erection because I love breasts. My aunt noticed my erection and started massaging me in the bath. But it still wouldn't go down... So my aunt did something even more lewd, making it an incredibly blissful trip.
