I came to a hot spring trip with my mom and aunt (big-breasted and plump)… "It's okay because you're a kid, right?" My mom and aunt decided to enter the women's bath together. However, more and more female customers came in, and I was surrounded by many breasts. As someone who loves breasts, I couldn't help but get an erection! Noticing my erection, my aunt tried to make it go down by jerking me off in the bathtub! But the erection wouldn't subside… In the blind spot of the tidying space, she secretly helped me release with blowjobs and paizuri! Furthermore, even more excited, my aunt and I went to the changing room…
