[Sakai Hamachi] The Mommy Next Door is My Sex Friend (COMIC AUN 2021-08) {Doujins.com}

When a busty mother-daughter pair moves in next door, young Yuuta is instantly smitten with Keiko, the curvy MILF neighbor whose snug sweater can barely contain her enormous breasts. Friendly coffee visits turn feverish once she catches sight of his swollen hard-on and offers some hands-on emergency first aid, milking him with her mouth before eagerly riding him raw, the thrill of their families catching them in the act only making them louder and hungrier. A pregnancy bombshell finally exposes the secret affair to both households, but between Keiko's beauty-marked smile and a sheepish love-at-first-sight confession, everything ends in joyful acceptance.
