No!

Lisa had no intention of bending over and taking it from that asshole. The other one was kind of cute and if he'd been the one with the handcuffs...

what was she thinking? She had to get out of there. She was fit and figured her best chance was to bullrush them, she hoped they weren't used to their prey fighting back so physically and maybe that would surprise this DKM asshole enough to make a mistake. She charged towards them dropping her shoulder. Before he could get his handcuffs completely free the frat brother went down. The other one dropped his shoulder to meet hers and she bounced off course but stayed on her feet. She moved towards the doorway and was a step through when she heard the click of a handcuff snapping into place. It took a second for her to register the feel of a fluffy handcuff closed snugly around her ankle. She looked down and sure enough the asshole brother on the floor had managed to get her ankle as he hit the ground. She sighed in exasperation. She was going to get fucked by DKM after all. Her pussy was dripping wet by now and the prospect of being taken but such a repulsive idiot, was... exciting. She looked away from him in shame, hoping he couldn't see the lust in her eyes. She did see his look of absolute glee before she looked away and the urge to slap him came screaming back. She couldn't believe how she was reacting to this, being captured and used was driving her insane and she realised, much to her own chagrin, that she was starting to feel impatient for his cock. As if on autopilot she felt herself move over to the edge of the bed, the handcuffs dragging on the ground. She bent over the wooden bedframe and reached behind herself to pull at the strings tying her bikini bottoms together. After a few short pulls the strings came loose and they dropped to the ground revealing her glistening pussy excited and ready to be taken. She steeled herself embarrassed by her actions but desperately needing to be fucked at the same time. She didn't look back as she felt him move behind her. She heard the click of a marker lid being removed and slowly felt marker on her skin as she was marked as DKM property. She groaned ashamed that she had let herself get into this situation. She looked at her sister, who was still moaning as the monster took her from behind. As if aware of Lisa's attention, Felicia opened her eyes and stared in horror as she realised her sister was about to experience the same fate she was. Lisa opened her mouth, wanting to explain it wasn't her fault, convince her sister (and herself) that she didn't want this when the DKM asshole behind her thrust forward. He entered her in one smooth thrust, sliding easily into her, despite his reasonable size, due to the state of her arousal. He confidently, almost casually, fucked her in no hurry but firm enough to have an effect. Before long she was moaning along with her sister. What Lisa had felt before was multiplied tenfold now that she was actually taking DKM cock and the thought of being another conquest drove her wild. She came, shuddering and gripping onto the bedframe with all her strength to stop from collapsing. The asshole frat bro fucking her chuckled to himself, obviously assuming it was his own prowess and not the situation that had brought her to climax so quickly. Lisa had always assumed multiple orgasms were a myth told by people trying to sell dubious pharmaceuticals but as he continued pounding into her from behind it quickly became apparent that she was going to be experiencing it very soon. She looked up, and saw Felicia staring at her in surprise. She was moaning even loader now and it seemed like watching Lisa get off was pushing her over the edge. Lisa had never felt like this before, she hated being used like this but it only turned her on more. Her nipples were starting to rub uncomfortably against her bikini top, rock hard from the attention her pussy was receiving and trying not to meet Felicia's eyes she untied her own top and removed it, giving her conquerer access to her breasts. He wasted no time taking them in his hands and squeezing them. He didn't show any prowess or skill in his touch, but something about the confidence and dominance in the way he used her breasts for his entertainment hit the same nerve that had been exciting Lisa and she came again, screaming out her orgasm for the whole frat-house to hear. She looked up again at Felicia, ashamed but needing to know her sister's reaction.

Felicia looked back at her, shocked but also clearly past the point of caring. As Lisa watched she saw 'The Monster' increase his pace to a blur and the slapping of his gut on Felicia's toned ass grew louder. He groaned and Lisa saw Felicia's eyes roll up as she shook with what Lisa could only assume was another orgasm. Lisa was sure she'd just been filled with DKM cum as had been promised. She knew it couldn't be too long before she shared the same fate. She was approaching her third orgasm now and the attention her breasts were still receiving was driving her to new heights of excitement. She felt the thrusts coming from behind her begin to get more erratic and knew what was coming. Sure enough a few moments later she felt spurt after spurt of DKM cum coat the inside of her pussy. She groaned, still embarrassed by what she was doing but the feeling of being marked by DKM so completely drove that thought out of her mind as she was hit with the biggest orgasm of the night. She shook with the power of it lost her footing, slipping off the now softened DKM cock she dropped to the ground, the orgasm continued and she shook on the ground for a few moments as the waves of pleasure passed over her. Eventually she opened her eyes and saw Sarah's wide eyed look of surprise. She looked away. She had been conquered by DKM after all, and she wasn't entirely sure she minded.
