[Itaba Hiroshi] Imouto to Yatte Shimattashi, Imouto no Tomodachi to mo Yatte Shimatta [KittyKatMan] [Decensored]

A favor to pose as his younger sister's boyfriend spirals when a compromising photo turns into the real thing, and soon her bold, big-breasted friends want a taste too, teasing since you asked for a threesome. Caught between forbidden sisterly hunger and her curious schoolmates competing for his naughty cock, every secret meeting melts into eager blowjobs, messy creampies and breathless group sessions where they admit this is seriously making me horny. As the cheating thrill and harem tension escalate from playful posing to shameless anal and sweaty, flushed threesomes, pretending becomes impossible to stop.
