Mistress Nicci is trying to get ready for her Valentine's Day date but walks back into her room to find you rummaging through her panties again. She says you're like a lost puppy always following her around and if you weren't such a looser you would have a Valentines date instead of having your nose in your step-sister's panties. She suspects if she leaves you alone with her panties while she's out on her Valentines date you will sniff and chew the crotch of her dirty panties. She had a feeling you would do something like this again so when she stopped off at the sex store to get something for her Valentines date, she picked up a cage for you... a cock cage for your pathetic little penis.  She proceeds to put it on you so you don't make a mess with her dirty panties while she is out on her date with a real man.  She decides she will officially make you her little puppy all locked up in chastity, and if you hopes to get out of the cock cage you'll have to behave and do what she says, but she expects you'll need a lot of training to be a good pup.   She proceeds to tease and temp you by lifting up her red lingerie showing off her panties and pulling them down to expose her plump, juicy ass.  If you behave yourself while she is gone, she may give you her dirty cum filled panties she is wearing so you can sniff and lick away. She might even bring her date back home and if her new puppy is good, she will allow you to sit by the edge of the bed all locked up and watch her fuck her date.
