Sway his decision

I could sense the hesitation and indecision in Marcus as he stood there motionless, speechless, and still dumbfounded. It was clearly evident that he didn't know what he should do, presented with the possibilities that lay before him. Sensing an opportunity to further take advantage of my helpless sister, I decided to help Marcus make a decision. I grabbed Kristi's cum-streaked hair and twisted her head, tilting it back so that she was looking towards me. I tightened the grip as I twisted her hair in a knot, causing her eyes to flutter as they focused in on mine.

“Kristi! Show Marcus how much you would like for him to stay and watch your performance today! Prove to him that you don't want him to leave. Let him know that he won't be let down!”

I chuckled at the pun as I let go of Kristi, who obediently turned her attention back to Marcus. She dutifully laved her tongue along his shaft, bringing both, him and his cock back to life. His cock bounced and swayed as she playfully tried to plant wet kisses upon the love lance. It was several long minutes before Kristi managed to capture the helmet into her mouth, swirling her tongue over the sensitive tip. It was at that moment that Marcus seemed to snap out of his trance, grabbing his sword by the hilt and using it to punish Kristi. He slapped her cheeks roughly with his broadsword, occasionally thrusting the turgid length deep into the recesses of her oral cavity.

I encouraged Marcus to continue as he thrust into her roughly at varying angles, threatening to punch a hole in the back of her head, or tear a hole through her cheek as he roughly rammed his rod in hard. “That's it Marcus! Treat her like the cock craving, prick pleasing, shaft sucking, weenie whore that she strives to be. Give it to her good! Give it to her hard!” Marcus obediently redoubled his efforts, following my commands. It was ironic how, now Marcus was following my lead instead of Kristi's, as he had done in the past. It made me wonder, how much could I influence Marcus simply by using Kristi? One look at Kristi, and it was evident that she had embraced her new lifestyle, her hands once again, buried deep in the vee of her unzipped jeans. I couldn't see much, but her excitement was evidenced by the growing wetness, staining the denim.

Unfortunately, I didn't have much time to ponder that question of how I could use these two to my benefit, as the doorbell summoned me away from the action in the basement. I was not worried about monitoring their activities, as I knew they'd be occupied for some time. At the door was Brad, Pete and Jeremy, three of the friends that were at yesterday's party. I invited them in and escorted them to the living room. It was difficult avoiding answering the questions posed, as to the meaning behind the cryptic invitations. I managed to keep them at bay, assuring that once everyone arrived, we'd get the party started and all their questions would be answered. Luckily, I was drawn away by the ringing doorbell once more, to find Austin, Chad and Eddie, all waiting to come in. Once again I was barraged by the questions, that were now gearing as to the whereabouts of my sister. I hadn't had much time to prepare for this as Marcus' arrival had come unexpectedly, but I was able to deter them with some music from the radio and some leftover soda from the day before. I only wished now, I had access to my dad's beer, but then again, I'm sure everyone would want to be sober to enjoy the entertainment. I returned to the door, where Dave, Freddie and George were waiting patiently. I was particularly thrilled at this point, since all the people that I left messages with, were already in attendance, meaning the last three were guarantees to show up. It was getting increasingly difficult to dodge their inquisition, but once again, I somehow managed, assuring them that when the last three arrived, everything would get underway. The sound of the doorbell was my savior as I opened it to find Hank, Ike and Karl waiting to join the party.

Twelve in all, plus myself, and Marcus! This was truly going to be a party to remember!

I informed everyone that the party would be moving downstairs, but that we needed to bring the party supplies with us. I handed out six full two-liter bottles of soda, which four of the guys each took one to carry. One took a large bowl of chips, while another took a bowl of pretzels. Someone grabbed the bowl of dip, someone else grabbed cups, another grabbed the tray of barbecue, and the last carried the buns, while I had the leftover birthday sheet cake. I made sure to lead the way, so as to ensure everyone's surprise was genuine. As we noisily made our way down the steps, the temperature in the cool basement suddenly spiked. A cacophony of cries, gasps, shocked murmurs all mixed together. It was impossible to decipher who said “Oh my god”, or “What the ...”, or “Jeezus”, or “Holy shit!”, amongst all the other indecipherable words that jumbled together.

Kristi was still on her knees with her hands diddling in her pussy as Marcus battered his ramrod into her skull. Drooling frothy white foam leaked from around the seal of her lips and his cock. Marcus instinctively and reflexively pulled away from Kristi, turning away to hide himself from the unbelieving eyes of the others. “What the fuck, Luke?”

Kristi, meanwhile, knelt there just as dumbfounded and shocked that my earlier threat had been carried out to fruition. She had stopped masturbating, but was too embarrassed to remove her pussy-coated fingers from within her pants. Her face was still smeared with the piles of makeup that had clearly run down her face due to tears and cum. Her hair was matted from sweating, and streaked with Marcus' earlier deposit. She looked a shambles.

I calmly placed the cake on the nearby table and had to physically pry the other supplies from the other party-goers, taking what they brought down and placing it on the table next to the cake. They all stood frozen, slack-jawed and speechless, staring at the spectacle of the girl of their dreams, subjugated in such a sexual manner.

It was time to put everything into perspective, so that everyone knew how this party was going to continue.

“You see Marcus? Yesterday, all these fine folks were at my birthday party. We were having a good time, but Kristi, thought it would be fun to tease them mercilessly, bending over and showing her cleavage to them as she served them food and drinks. She thought it was fun to make them think she liked them, when all she was doing was tormenting them. She never had any intention of letting any of them get close to her. She thought it was fun to watch their cocks twitch in anticipation, probably wishing they would go home and jerk off to thoughts of her.”

I was now staring at Kristi, whose eyes were lowered to the floor in utter shame and embarrassment. “She thought it was funny how she poked fun at me in front of them, and how she smashed the cake in my face.” I walked over to Kristi and pulled her hair up once again, bringing her head up to look at the group of men gathered around the room. “So today, Kristi thought it would be best to apologize for her behavior yesterday. The only problem is that mere words are not enough, are they Kristi?” I shook her head for her, not giving her an opportunity to object. “And I'm sure you'll now agree, that nothing worthwhile comes out of her mouth, and that her mouth is only good for one thing! That was evident when we walked down here Marcus!”

I turned back to the group and instructed everyone to take a seat, which they eagerly did, including Marcus. “We're going to have another party today, and Kristi will be our perfect hostess ...”
