The stairs had collapsed at the third floor, forcing them to squeeze tightly past the debris. Tiffany found herself having to help Brooke through the tightest spot, as the girl's more generous curves made it hard for her to fit.
Pressed together, Tiffany found herself badly turned on, the scent of Brooke was driving her wild. Tiff had never noticed it before but a strong sugary vanilla scent was pouring off her short stack sorority sister. It was intoxicating. She wanted to kiss her, squeeze those spectacular DDs. Tiffany's clit was pulsing, engorging beyond what should be possible. She could swear she could feel her panties getting tight in the front.
Finally on the third floor, Julia suggested splitting up to find another route up.
'I'll go with Brooke!' Tiffany heard her own voice say. It had been reflex.
The rest shrugged, and formed their own pairs.
As they explored, Tiffany could barely keep her hands off Brooke. She also could feel something happening, something terribly wrong. Her panties were very tight, and a quick glance and grope when no one could see confirmed a rather masculine bulge just in front her pussy.
The scent of Brooke kept terror from overcoming her. It kept expanding, changing. Tiffany could still pick up the vanilla sweetness, but now she could pick up a cinnamon spiciness. Was she just noticing it now, or was it new? This kept seizing her thoughts and drawing her attention from whatever was happening in her panties.
As they climbed over more debris, Tiff's eyes were glued to her curvy friend's ass. She realized what she was feeling, masculine lust. She wanted to bury her cock between those plump round cheeks.
'Dead end, coming back' Brooke announced as she started backing up.
As she squeezed past, Tiffany's resolve broke. She shoved the shorter girl against the wall, and kisses her. To her surprise, Brooke didn't resist, she returned the kiss and pulled the blonde in tighter.
Tiffany's left hand slid down along Brooke's soft stomach, sliding into her waistband. The brunette's panties were soaked, her clit a gumball. Her fingertip circled that sensitive nub as they passionately locked lips.
Brooke returned the favor, her hand sliding down inside Tiff's underwear. Without hesitation, she wrapped her hand around the erect cock she found there.
Under Tiffany's fingers, Brooke's clit swelled. It pushed forth, undergoing a metamorphosis into an impressive eight inch manhood. Well proportion balls swelled and dropped into place below.
The two hermaphrodites masturbated each other with abandon, oblivious to everything but their desire. They came almost in unison, adding to the wet mess of their panties. They slid down the wall, spent.
At first neither spoke. Brooke broke the silence. 'We can't tell the others. We get out of here, and we go straight to a hospital.'
'No, we go to see my sister. She's an OB GYN, or almost, she's doing her residency at the campus hospital.' Tiffany said.
Brooke raised an eyebrow at this. Tiffany shrugged 'She got the brains, I got the body.'
Just then they heard Tammy's voice calling for them.
