Your dad just re married and she's hot, kinda ditzy and fun but seems pretty slutty because  she's always flirting with you and your buddies and walking around showing off her body and making sexual comments to you. Especially when your dad is traveling for work. You know she wants your young cock so bad, especially because your dad is twice her age. You can tell she wants to fuck but you're not sure if you should make a move.

Its Christmas eve tonight and the 2 of you are all alone and decorating the tree. Your dad has been out of town all week,  but allegedly is arriving home around midnight.  You want a small  xmas party so  invite your 2 best friends and she gets really excitedt to hear they are coming by. Within minutes of them arriving, she's undressing and showing off her big ass and talking about how much she loves to suck cock. She suggests to suck your friends off while you watch and wants you to record everything. You do as she wishes. Blowing them both while you record snd watch is getting  her so horny that she decides to ride both their cocks and let them cum in her pussy. 

After they leave she begs you to fuck her on the couch  before your dad gets home and you say yes. ..

Its the best xmas eve you ever had.
