One day, when I went to her house to play, her cute younger sister 'Natsuki' came to greet me. Natsuki, who clearly has bigger breasts than her sister, was bra-less and teasing me with a glimpse of her boobs! 'Please do something about the stirring in my womb!' she demanded, not a relationship but immediately asking for baby-making! I knew I shouldn't get excited by her horny, pregnancy-obsessed body, but I did. As a result, I ended up having my semen squeezed out of me in secret!
