Your mom has had a rough day, and she really wants to unwind in a relaxing bath. She knows that she had better check on you first, and make sure you haven't gotten into any trouble today. Ever since your father left, she's really needed you to step up and be the man of the house. You can't help but stare at her ample cleavage, which no reasonably-sized robe could contain. She gets annoyed when she notices that your attention is elsewhere, and is appalled when she sees the bulge in your pants. She gets up to leave, but you convince her to stay. Can she blame you?

Her demeanor shifts when you pull out your cock and start stroking. She had no idea it had gotten so thick, she tells you with a bit of pride in her voice. Her curiosity gets the best of her, and she becomes desperate to have your thick cock in her grasp. It's been so long. Maybe she'll just have a taste too...
