"Sophia dear, why don't you get Melissa out of those straps?" Miss Rose suggested, getting off the bed.
"Yes, Miss Rose," I said obediently.
I began to unbuckle the straps holding Melissa's knees up while Miss Rose went and gathered more supplies for whatever was coming next. Once Melissa's legs were free, I worked on releasing her wrists from the bonds as well.
"How would you girls like to play a game?" Miss Rose asked. "A little competition of sorts, to see which of you is a good girl, and which is of you is bad."
"I'm always in the mood for games," Melissa said eagerly as she sat up.
"Sure, I'll play," I said nervously, knowing full well whatever game Miss Rose had in mind would push me like she'd done the last two days.
"Good, let's get Sophia undressed. Melissa, will you do the honors, please?" Miss Rose asked as she carried a few lengths of rope in her arms.
"Yes, Miss Rose," Melissa answered with a smile.
The buxom woman clambered off the bed and beckoned for me to follow her off. I stood up next to Melissa and she began to unstrap the harness from my waist.
"This game will have three rounds, each different from each other, and as is the theme with everything I do, the goal of each is to not cum," Miss Rose explained as Melissa unclipped my thigh high stockings from the garter belt at my waist and rolled them down my legs. "If you cum, you lose the round. Win two rounds, and you will earn an orgasm from me in the manner of your choosing."
The idea of having Miss Rose make me cum the way I want her to was very enticing. However, the game was still ambiguous, and I already knew it was going to be difficult, especially with as highly aroused as I already was.
"When you're done undressing, come here and sit down on the floor," Miss Rose instructed. "You'll be competing against each other, trying to make each other cum, whilst also trying to stave off your own orgasm."
Melissa smirked devilishly at me as she reached around my back to unclasp my lacy black bra. It was as I feared. Melissa had more experience than me, and would likely have an easier time resisting orgasms. I had my work cut out for me already and I still didn't know all the rules. She hooked her thumbs in the waistband of my garter belt and panties and slid them both off together. Melissa bit her lower lip seductively as she stepped back, drinking in the view as she saw me naked for the first time. Being naked so much for Miss Rose gave me the confidence to not instinctively cover up in front of Melissa, and it made me feel good to know that Miss Rose wasn't the only one who thought my body was attractive.
Together, we walked over to where Miss Rose stood in an open area of the bedroom and sat down on the soft carpet.
"Get close together, and wrap your legs around each other like your going to scissor," Miss Rose commanded.
Melissa and I obeyed, scooting close to each other. I put my right leg over her left, and she put her right over my left leg. The whole time, Melissa had this look in her eye that made my confidence shrink.
Miss Rose took a length of rope and began to tie Melissa's arms behind her back starting at her wrists and wrapping her forearms together up to her elbows the way she'd done to me last night. Without the use of her hands to stabilize her, Melissa wobbled, and her legs instinctively tightened around me to keep her from falling over. The motion pulled her closer, until our mounds made contact and our faces were mere inches apart. My womanhood already throbbed from the touch of Melissa's against mine. Miss Rose then came around behind me and tied my arms the same way. My legs wrapped tightly around Melissa too, locking us together as I felt myself lose stability. Miss Rose tied the rope tightly so that my elbows touched, making my chest stick out a bit.
Finally Miss Rose took a small, silver bullet vibrator and turn it on. She reached between us and both Melissa and I gasped as she wedged it between our pussies.
"This first round is simple. This vibrator must stay pinned between your pussies. Do not let it fall," Miss Rose explained. "Like I said before, if you cum, you lose, but you can do whatever you want to try to make each other cum. You may begin."
Melissa immediately squeezed her legs, mashing the bullet between us and forcing it hard against my clit. The pleasure took hold of me and Melissa took advantage of my lapse in concentration and shifted her weight towards me. I fell backwards onto the carpet, her legs and my bound arms awkwardly pinned under me, and she quickly maneuvered herself on top of me. Right away, I knew I was out of my element. I was no doubt stronger than Melissa, but she was bigger and heavier, and wrestling was not my forte. Not to mention she'd just had an orgasm and I was still close from being edged by Miss Rose earlier.
"Nnng-fuck, that's not fair!" I whined. "You're bigger than me!"
"That doesn't mean you can't fight back," Melissa said, starting to grind against my already sensitive clit.
She was right, I still had to try, but I was afraid trying to wrestle would only hasten along my orgasm. I took a deep breath, regained my composure, and twisted my hips to try and roll Melissa onto her back. It took three tries but eventually I succeeded in rolling her off of me, but I couldn't get enough momentum to get on top, so we ended up on our sides, still locked together with our legs wrapped around each other. I had to try something else to increase her pleasure, so I buried my face in her neck and started kissing and flicking my tongue along the sensitive erogenous zone.
Melissa moaned in response to my kisses, but it didn't have as much of an affect as I'd hoped. She still had her wits and was able to roll back on top of me. This time she bent down, laying all her weight on top of me and pressing her big, plump breasts against mine. She began to hump furiously against my pussy, and the friction combined with the vibrations made my eyes roll back. I could already tell this would be over quickly. I had been too pent up before this game even began.
"Oh god... come on..." I moaned gutturally in frustration.
