[Reducing Mosaic]SSIS-469 The younger sister of the childhood friends I'm dating has actually been in love with me all along, and her older sister, driven mad by jealousy, tries to seduce me with her bare breasts. Koyoi this way...

I'm dating the younger sister of a pair of childhood friends. One day, when I went to her house, her older sister 'Konan' was clinging to me in a no-bra outfit! I hadn't noticed, but it turns out she has huge breasts. Her nipples were poking through her bra-less camisole, and a bit of her areola was visible, which was so erotic that I couldn't hold back my erection! 'Don't you think my boobs are better?' Unable to resist her H-cup aggressive promotion, I secretly groped her breasts, enjoying their fullness, and ended up crossing the line.
