Your step-mom is upset with you and she called you into her room to have a talk. She has to sit up on the bed with her. She's upset that you take her for granted and don't appreciate all she has done for you. After she grew you in her belly, and suffered as it grew large, and pushed you out of her vagina, stretching it out and damaging her body, you have the nerve to be a disrespectful step-son! She tells you that she's going to punish you for your own good, and makes you take off your clothes. She threatens you and you're terrified, and do as you're told. She is wearing a sexy outfit while she lubricates your butthole and you're so confused and you have strange feelings in your body. She inserts the hose of the aquarium pump and says it is perfectly safe, she's going to put air in your belly so you know what she suffered being pregnant with you. It slowly inflates and your step-mom is so good looking that with the pressure in your belly, you start to get a hard on. At the same time, your belly starts to cramp and you cry out in pain. Step-Mom tells you to stroke your dick, it will make it less painful, she's such a caring step-mommy. You do as she told and it distracts you from the air filling up your tummy. You get bigger and bigger and it's such a strange feeling, but arousing. She slaps your belly and even kicks it to simulate the kicks you gave her during pregnancy. You beg her to let you go and take out the air but she's determined that you'll look several months pregnant before she stops. You're so afraid you'll explode! But maybe you deserve it for being such a bad step-son. Step-mom gets aroused watching you suffer and get bigger and bigger, swelling painfully. You're helpless as you're so large now and it hurts too much to move. Now you know what it was like for her! She lets you grow so large and taunts you about how you're going to pop like a balloon and then she will be free. You can beg and plead, but there's nothing you can do. Step-mom is tired of you and tired of raising such an ungrateful step-son. This will be your final punishment. Ends with a pop sound effect and fade to black.
