You go into stepmom's room one night when she's reading and tell her you need to chat. You've found out that she has pawned some very expensive earrings given to her by her husband for their anniversary and you know he'd be furious if he found out. She tells you it's none of your business and to keep your mouth shut but you tell her you'll keep her secret only if she does you a favour. To her disgust, you tell her you want her to give you a handjob. She tells you no and that it's totally inappropriate! After some pushing and promise of blackmail, she finally caves and reluctantly pulls your cock out of your pants. She is visibly disgusted from touching you and is grimacing as she's stroking you. She berates you for being such a perv and tells you this is a one time thing and it will never be happening again. You tell her you want to see her tits too and she agrees if only it will make you finish faster. She jerks you off topless as she continues to tell you how disgusting this is. After a while, she tells you maybe it's not entirely your fault, she knows she's a MILF and it must be hard for you to resist seeing her around the house all the time. She notes that you do actually have quite a big dick and seems impressed by it. You're thinking she's starting to enjoy this as she's becoming a bit more encouraging and engaged with stroking you. She starts really getting into it now, dirty talking about your naughty fantasies just like you've always wanted. She encourages you to look at her big hanging tits while she milks you, telling you this is going to be your naughty secret. She tells you to let go and cum for strepmommy until you bust a huge load all over her hand.
