Her underwear starts to revolt

The two girls make their way to the front as Gigi makes a subtle gesture with hand once again for Tammy’s thong to ride up again as she walks to the front of the class. Tammy gasps as her thong shoots up into her pussy lips and more specifically into her clit. Gigi laughs to herself seeing Tammy struggle to walk as the thong tightens further into her butt crack and pussy slit. The teacher asks Tammy if she is alright and she reassured her teacher it is nothing but she realizes she cannot adjust her wedgied thong in the front of the class so she bears with the uncomfortable yet erotic sensation.

Tammy introduces herself as well as mentioning partially Gigi but presented the project as if she did most of the work. Gigi became enraged by Tammy’s belittling comments and proceeded to step up the punishment. Gigi envisioned Tammy’s bra being a matching color to her thong and gesture her fingers as if she was cutting her bra straps. Tammy was speaking and felt her bra straps suddenly feel looser on her shoulders but not enough to stop her from continuing her presentation. Gigi then gestured her hands and envisioned the clasp on the front her bra to pull apart. Tammy stopped mid-sentence as she heard the bra clasp snap and felt her bra slide down to the bottom of her turtleneck.

Tammy’s breasts and nipples were now clearly outlined in her shirt as well as everyone heard her bra clearly snap since she was the only one talking. Tammy started to get flushed as she thought about her 32C breasts now naked and pressing against the material of her turtleneck, hoping they were not too visible. She knew that her thong had been still turning her on so she knew her nipples had to be poking through from her horniness. Gigi was seeing Tammy squirm and enjoying every second of it. Gigi was ready to take this up a notch as well.
