[Kawazuko Chouji] Imouto Ijiri to Mama Asobi - Mama's satisfaction

With her husband away on a long overseas trip, a lonely housewife's boredom melts the moment her son Haru walks through the door — and it isn't long before he's mounting her from behind, her heavy breasts pressed into the sheets as she pants and cries out under his relentless pace. Her beauty-marked face twists in open-mouthed bliss with every deep thrust, each climax leaving the mature beauty more satisfied than the last until she welcomes his release inside her without hesitation. By the final page she cradles him against her chest with a contented smile, teasing that a little brother or sister is on the way and Daddy will just have to be told.
