Deviant stepmom knows best in her little black dress

"It was such a nice service, right sweetie? My husband would have liked it. I can't believe he's gone. It's just us now. We'll get through this rough patch together. You help step mommy & step mommy will help you. You look exhausted baby. Why don't you lay down. I'll sit with you & we'll relax together. Baby you seem tense. You should stretch your body out, get your veins flowing. There you go...close your eyes...relax & stretch out your arms." (As stepson closes his eyes, stepmom grabs handcuffs she secretly brought in with her & quickly cuffs him to the bed. The sound of the clanking metal raises her boy's awareness but once he realizes what's happened, it's too late. He's bound & stepmom straddles him. She teases him about being locked up & waves the keys in front of his face. Stepmom is wonderful & sexy but also deviant & sadistic. No telling how she'll behave. She needs her darling boy to love, use & punish. Stepson is intimidated yet aroused. How far will stepmom go..?
