You have some very revealing photos of Mom with another man, and you have no qualms at all about blackmailing her hard. You've got some ideas already. As you wander into the kitchen, she brings it up and says she believes that you won't tell anyone about this little issue, even though you have a rocky relationship. She trusts you. You chuckle and let her know you'll be blackmailing her. She's shocked. But... accepts this, as you really don't get along. But she maybe doesn't expect what you hand her... a diaper, a vibrator, and a butt plug. All meant to be used at the same time. As she's giving you the blowjob of your life. Reluctantly, she agrees to all of it... presses the butt plug inside painfully, tries to press the vibrator in her pussy and slowly gets it in... and pulls up the diaper... before bending down, dropping a few drips of milk so as not to taste her own son, says all she asks is you NOT to cum into her mouth, and finally takes your cock into her mouth. And just because you can? You blast a big load right into that whore mouth of hers. Your cheating Mom. She deserves it.
