[Karakuri Korokke] What if My Mother Tried Giving Me Sex Lessons? [Full Color]

A devoted mother takes her son's sexual education into her own hands, offering hands-on practice that quickly spirals far beyond a single lesson. Their arrangement escalates into daily morning deepthroat sessions behind his girlfriend Ruri's back, until she appears at his bedroom door to 'congratulate' him on getting back together—with an open invitation to finish inside her one last time. A postscript epilogue reveals the consequences of all that unprotected practice, as the heavily pregnant mom welcomes her 'darling' home.
