[Yuruchin Kyouso] Twins Love (COMIC LO 2021-12) {Mistvern}

A NEET uncle gets roped into babysitting his sister's twin nieces, only to find himself already dating both mischievous girls—meek Moka and spunky Moe, who compete shamelessly for his attention. The sisters trade sloppy deepthroat blowjobs and take turns riding him before pressing their slick, dripping bodies together to demand he pick a favorite with his dick. When neither will back down, the twins corner their exhausted uncle with a proposal he can't refuse: a permanent three-way relationship where nobody has to choose.
