My birthday is May 19th, so I decided to make this to celebrate! Don't forget? You come downstairs to find your step-mom making eggs, acting strangely happier than normal. She asks why it's strange for her to feel good on a day like today, but all you say is... Sunday? She gets discouraged, but ignores the fact you forgot her birthday. You say you have plans and will be home for lunch, but instead you go out with friends. Upset and alone on her birthday, your step-mom results in some self care masturbating on the couch after reading some smut. You come home earlier than expected, however, and catch her touching herself. She is shocked, as are you. She sits you down when you say you're sorry for forgetting her birthday, and she comforts you. However, after getting caught staring at her boobs, you pull her in for a kiss. She is shocked, but she kisses you back, eventually getting down to suck your big cock too. She climbs ontop of you and starts riding. She wants to cum, and she doesn't want you to cum in her. She says to hold it while step-Mommy gets closer, wanting to cum bouncing on her step-son. You try to hold it, but unload as she starts cumming. She protests, but you cum deep inside of her, letting it drip down her leg... She is angry, but she says it is okay. When she walks away, you take the chance to wish her a happy birthday... Aren't step-sons great?
