Mo attempts to pull out, but get's stuck.

Mo could feel Alexcia's walls constricting further than before and could sense the librarian was close to her orgasm. She watched as librarian's body contorted and the convulse. Then right before an orgasm could be triggered, Mo quickly attempted to break free from the clenching walls, but forgot Alexis's legs were locked behind her ass. The librarian moans erupted and despite Mo's struggle Alexis legs pulled her deep in. Her body convulsed violently as her body was rocked with what was one of her most intense orgasms. Copious amounts of fluid surged out from all around Mo's deeply penetrating cock. Mo was suspended above the librarian and moaned in unison as her cock was giving a more rigorous massage from the constrictive walls of the librarian. Mo had been able to begin a low and steady movement through the vice grip of the librarians walls as she had begun her descent from the high of her orgasm.

"Oh my god, I've not come that hard in a very long time." said Alexis through gasps for air. Mo smiled at the librarian's innocent confession as she continued to saw her cock in out of her slowly. "Why do you have such a sinister smile on your face?" asked Alexis still breathlessly.

"If you think that's the only orgasm you're going to encounter during our mating session, you have no clue what you're in for," Alexis looked at Mo as she found her self caught on the labeling of their session as mating. Before she could ask for elaboration of what the succubus meant by matting session, she yelped as she was flipped over like flap jack on Mo's cock. She now found her self on the couch on her knees and her hands draped over the back of the couch. Looking over her shoulder she peered back at Mo who had took a firm hold of her hips and Mo drew her self back until just the tip of her cock kept the librarian's pussy open. Her eyes were honed in on the the lips that held onto her barely inserted cock head as she held there for moment. Alexis's innards had a fire burning for the need of burial of Mo's cock and her pussy lips that were kissing Mo's tip gently seemed to shutter as if trying to suck the cock back in. Her mouth agape as the growing need of fulfillment cascaded over her body. She tried to push back onto Mo's cock, but was stopped by her hands that gripped her hips tightly. The librarians pussy juices were leaking out, coating the tip showing that entry was permitted and welcoming for the large cock. Whimpering could be heard from Alexis as her body felt riddle with withdraw and as she peered once again over her shoulder, her eyes lit as she watched the succubus slightly lean back.

With great ****, Mo slammed her cock hard and deep into Alexis who let a loud moan as she was completely filled by Mo's cock. Mo repeated her retreat and slammed back in. Harder and quicker with each motion. The pleasure rippled across Alexis body and as if being reintroduced to a **** for the first time, sending her into frenzy, pushing back into each slam of Mo's increasing tempo thrusts. The sound of clapping skin and soapy wet noises echoed in the small study as the two fucked like rabbits. Both profusely sweating and edging each other on in pleasure. The librarian's eyes rolled into the back of her head as Mo's cock bottomed out into her. Alexis was being stretch far more than she'd ever been and the electrifying stimulation from the power fucking had stirred up another impending orgasm. Burring her head into the crevice of the couch like a ostrich she let out a load moan as she climaxed again.

Mo gritted her teeth as she pushed through the gushing pussy and the constricting walls. Sliding her hands over Alexis's ass, she grabbed around the torn area of her clothing and tore the leggings more revealing more of Alexis's ass. Reaching down, she pulled Alexis's head out the couch by her hair and both groaned at the new position. The sound of slapping flesh echoed more in the room and then with one pull back, Mo changed her thrusting into long power strikes. Alexis let a load gasp during each strong thrust. Mo's hands had transitioned to grasping the throat of Alexis and pulled the librarian to her feet while still in a semi-bent over state, testing out the dancers flexibility. Sliding her hands down to the arms of Alexis, she pulled her backwards further, enabling her cock to get deeper. In steady motion, Alexis bounced back and forth on Mo's cock. The overbearing pleasure of the domination had sent her brain to mush as she no longer could control her reaction to the succubuses ****. Mo watched her victim's body go somewhat limp to her thrusting and decided on the next move.
