[Akarui SM (Hikitogu)] Henai Mama [Kinsei Translations]

A doting mother with gigantic breasts that strain her blouse discovers her crossdressing son sporting an erection he definitely wasn't supposed to have, and there's only one solution — the punishment room. Bound in a straitjacket and ball gag, the trembling boy endures his mommy's loving brand of discipline: enema inflation, orgasm denial, and relentless teasing that leaves him drooling and ahegao while she pats his head and coos that he did so well. Twisted maternal devotion has never been this possessive or this thorough.
