Recently, my wife's mother, who has begun to worry about her plump mature body shape, has become so embarrassed I got an erection

I saw my wife's mother changing clothes after being able to peek at me. Her body line is tightly tightened by her tight, corrective underwear... Her beautiful areolae, huge breasts that are about to pop out of the fabric... Her son-in-law is completely captivated by her voluptuous body. If things continue like this, I will betray my wife one day. Before he makes a mistake, he seals his feelings for his stepmother... but when he comes home drunk, his stepmother, who should have been sealed in his open body, begins to fuss.
