Poor Lisa. Bro B scores an easy five points.

Lisa watched herself in horror in the bar mirror as she turned her back on the frat boy's exposed cock, before undoing her bikini straps, bending over and arching her back in complete surrender. She knew perfectly well that the cocky douchebag was about to plow her into submission before inseminating her in front of her sisters.

She heard her sisters' laughter turn to gasps as they realized what she was doing.

"Lisa, no!" said Beth in shock, covering her mouth to repress fresh giggles at the shameful way her sister was behaving.

"Not these douchebags!" added Sarah.

"You can't just let him win like that!" cried Felicia, though she too was stifling shocked laughter.

Bro B looked each of the sisters in the eye before saying "I told you so."

Lisa heard a click as he opened his marker, and groaned as she felt him draw D-K-M on her ass. She was officially marked, her ass now belonging to this douchebag. "Yup" the shame filled part of her thought "it sure does".

Bro B penetrated her without ceremony. She gasped, and hear her sisters gasp in sympathy. "A new DKM record!" said one of the other watching Bros. "Meeting to fucking in less than 60 seconds!" Bro B let out a jubilant "Wooo!" while all 4 sisters groaned at hearing this dubious honor. Lisa really hadn't put up much of a fight.

She tried unsuccessfully to stifle her moans, but before long she was unable to keep from letting out submissive little noises with each of her conqueror's thrusts. Bro B gloated obnoxiously over his prize even as he fucked her. "Sure is a tight pussy; I wonder if you other girls are this tight?" he said while staring at the sisters. None of them could meet his gaze.

Finally, she felt his thrusts become less regular and realized the the Coup de' grace was near. "Smile for the camera" whispered Bro B into her ear, and she couldn't help remembering Felicia's comment asking her about what face should would make for the Wall of Shame. Sure enough, another Bro was standing in front of her on the other side of the bar with a cell phone aimed at her. Bro B roared "I AM A STALION!" as he emptied his balls into her, pushing her over the edge and no doubt making an excellent Wall of Shame picture.
