Encouraging you to get penetrated makes stepmommy cum so hard

Hey boys...I came upstairs to see what you two wanted for dessert after we eat dinner. I was thinking maybe you both would like to have... each other. Sweetie, I'm not stupid. I know exactly what's been going on here since your friend came over. Don't try to be slick. Look at your raging hard-ons! I can totally hear you from downstairs.  You're both going through that "experimental" phase. Yes, he's a boy. So what.   Here's the thing...you two are under MY roof. I should call his stepmom and tell her...but I'm not that kind of stepmom. But I do INSIST on getting a front-row seat to your naughtiness...or else.  Mmm, I knew you'd see it my way.  Stepmommy loves masturbating to boy-on-boy action and watching a tight ass gets stretched for the first time.  Seeing your face as you experience the best orgasm of your fucking life while having his cock penetrate you so deeply will make us all cum so hard together...
