[18master] Musuko ga Byouki ni Narimashita. [Full Color] [mare_mio]

When a mother realizes her son's sickness has left him aching for release, she tears open a condom and offers to relieve his pain herself, murmuring that this kind of act should never happen between mother and son. What begins as one desperate act of care a month ago has become a shameless ritual—she rides him with eye-rolling, tongue-out bliss, cries that she loves him too, and proudly shows off the flood of cum dripping from her well-used pussy. All the while her furious husband screams at them to do it in their own room, and all she can offer him is a blissful 'I'm sorry... Honey' as she keeps happily taking her son's cock.
