Försöker något nytt med min flickvän

Abby and her boyfriend, Nicky, are exploring more and more new things in bed to spice up their romance. So, when Nicky calls Abby to come to his stepmom's house one afternoon where they could have some alone time, Abby arrives wearing just a romper, no underwear. Nicky tells her he has something he wants to try, and she allows him to handcuff her wrists and ankles to the bed. He then starts tickling her, Abby giggling uncontrollably. Nicky is having a great time tickling his girlfriend, but he knows she wants her pretty pink pussy played with since she is bound for his pleasure, so he pulls aside the bottoms of her romper to dip a finger into her already wet pussy. He alternates between teasing and tickling Abby and fingering her until she squirts, driving her absolutely crazy. Just then, Nicky's stepmom comes into the room, and catches the couple in the act! She is furious and gives them a talking-to, but she is a fun stepmom, so she has an idea that will make EVERYONE happy...
