Sierra loves being the center of attention, and she's gotten quite good at holding the spotlight. The bigger the audience, the faster her bulge starts to swell. The tight grey yoga pants she wears leave nothing to the imagination. Everyone in the room can see exactly what she's packing, and that's her favorite part. When her flexing muscles are upstaged by her growing erection, which steals the spotlight easily. Sometimes Sierra waits til she's hard to strike up a conversation with someone new, just to watch them struggle to keep their eyes off her stiffening cock.
