I picked up a little surprise on My way home from work today... and My bimbo-brained sissy girlfriend has no idea what's in store! She's been locked in a tiny pink chastity cage under My control for so long that she's found... other... ways to play with herself, behind My back. I finally found her hidden stash, so I know exactly what kind of embarrassing things she's been up to while I'm away! No matter, I'll just incorporate this new type of play into our dynamic... by making pegging the only way she's allowed to have sex from now on! To make sure she can't squirm away or protest, I handcuff her behind her back and stuff her cute lace panties in her mouth, holding them there with My hand over her mouth as I sensually pound her slutty hole from behind. Her embarrassment and hesitations simply melt away with Me in charge... and all is as it should be.
