My niece, whom I hadn't seen in years, had grown incredibly cute and developed enormous breasts. She was completely unguarded, with accidental cleavage and panty shots, and although I thought I shouldn't be thinking this way, I was getting aroused. Then she suggested we take a bath together, and her G-cup or larger breasts kept rubbing against me in the narrow tub, causing an involuntary erection! Seeing this, my niece didn't find it disgusting but was instead highly excited and even demanded oral sex and raw insertion with internal ejaculation. So I ended up having continuous internal ejaculations with my niece!
