You're in your stepmom's room in the evening, venting to her about some issues in your life. She's listening and absent-mindedly rubbing lotion over her arms and neck like she does every night before bed. Then she opens her robe and her hands slip lower, from her chest down to her full natural breasts. She massages the lotion into the skin of her boobs for a second before realizing what she's doing! Having her breasts out in front of her stepson is so inappropriate! Then she laughs it off, oh it's fine, it'll just take a second for her to finish. But she notices that you're getting... excited. She tells you it's natural, and you should come closer and put your dick between StepMommy's tits. She encourages you to hump into her warm, soft breasts. After all, it's not like you're really having sex!
