Mommy's Little Sissy: Aerobi-shame
*chuckle* You do love Mommy-bottom, don't you? So irresistible. So sleek and shimmery. So luscious and round. Poor little sissyboy. Just can't help himself.
Someone's going to see your little bulge and figure out you're a sissy. Don't ruin it today - you're so girlish-looking, no one would be able to tell you were anything other than a girl who's a bit flat-chested.
Do you really want all of the women in the gym to think you're a pervert? That you get hard from wearing white girls' tights, and prance around in a hot pink girl's thong leotard like a sissy? That you just snuck in today to watch women work out in their tights, so you could play with yourself?
Because that's what they're going to think when they see your teeny weenie bobbing so insistently against your leotard crotch.
