Imagine shuichi pounding his cock into you. His face is red and you see tears rolling down his cheek. It feels so good for him he looks like he's gonna cry. He says sorry mommy for being so horny. You caress his face and kiss him, his breath is so hot. You tell him to enjoy it inbetween your sensual moans.
He nuzzles your sweaty breasts and sucks on them while the bounce around.
Your husband is already at the front door, hearing your moans.
Your marriage is over and you'll likely lose custody of your son.
He says he's gonna cum and you think about what a pathetic mother you are.
He cums inside you, your back is arching.
You feel your son's hot thick semen entering your womb. The door swings open. Your husband is shocked to find you cheating with the son you helped raise. You stare at another, while Shuichi's copious amounts of semen still entering your uterus. You turn around to face your husband, you stretch your pussy to show him Shuichi's hard work leaking out.
Your husband runs off to throw up.
You tell Shuichi to fuck you from behind now while brushing some sweat off your forehead.

Your husband is throwing up in the bathroom. He sees the dinner you made yesterday that you ate as a family in the puke.
You stand at the doorway, with Shuichi still inside you. He's making cute boy noises as he plunges his dick in and out.
His semen is overflowing inside you, his cock is churning it.
You feel you son's semen drip out onto your legs and travel slowly down. There's so much it's like you pissed youself.
You make moans that your husband never made you make. You make him know that you prefer your son's cock to his.
You failed as a mother and he as a husband.
Shuichi releases another load inside you, it makes a wet glopping sound. He pulls his cock out and you kiss Shuichi behind you.
You husband is crawling towards you, he begins licking his son's semen out of you. He's mind broken.
Shuichi continues to make cute noises as you play with his sensitive cock.
