Tonari No Sumire-san (“My Neighbor Sumire-san”) [English], by Karasu

Because she feels neglected by her husband, a smoking hot woman (I’d say she looks 25 ?) gets drunk on alcohol and crashes at her male neighbor’s flat, effectively seducing him in the blink of an eye. He was dreaming of making her his “possession”, he found he was nothing more than a playtoy fling – but does it really matter, after all, «Doesn’t matter, had sex» ©®™
The story was unpretentious, the art was quite nice (on the minus side: white hole censorship, on the plus side: THOSE BREASTS!! ) but I fear the carefree adultery will put off most of you guys ?

Credits are for Ark, Capt. Crunch, MrWayne from LewdWaniBootleggers, commissioned by CellFT, thank you guys! ^_^

–Update: this is now in TANK scans! Much less censorship, and better image quality!
Thanks to Viacheslavovich and Mysael

–Update #2: good news, this share is obsolete. It’s now part of MESUhame IKIzome, a 238 pages long manga
