Get on your knees. Keep working on those nipples. Pinch and tug on them. Pull good and hard so that a little sissy moan just escapes those pretty red lips.
I think when Mel gets home, we can perform a little experiment. I'll set up a chair and computer just like I did before. We'll sit down one of the big muscular guys she's bringing home in front of the laptop. I cue up a bunch of your sissy videos and play them on a loop.
Of course, you'll be on your knees with your head on his lap, you can stare at his cock, but you are not allowed to touch it!
