I suggest you read Chapters 1 and 2 of this story; this chapter picks up from there.
*************************
Bob followed me as I went through the door to return to the bedroom. After we entered the bedroom, I turned to him, put my index finger on my lips to shush him, and pointed toward the chair sitting against the wall in the bedroom. I motioned silently for him to bring it over next to the bed, knowing that with her blindfold on, Ruth would not be able to see what was going on. He did, and with my hand making a downward motion, indicated that he should sit in it. As he complied, I glanced at his robe which had fallen open as he sat, and could see, not surprisingly, that he was once again getting erect.
I sat down on the bed to Ruth's left, on the opposite side of the bed from Bob, close enough to Ruth for her to feel the heat of my body on her naked skin through my robe. I lightly grazed my fingers over her left breast, and both of her nipples immediately sprang to attention.
"How are you doing, my pet?" I asked. "You may respond."
"Truthfully, a bit frustrated," she said.
I chuckled softly as I continued to run my fingers over her breasts. "I'm sure you are, my dear. I think that when I do give you permission to speak, that you need to call me something special. Your Mistress would be appropriate, don't you think?"
"Yes, Mistress," she responded, immediately complying with the role play I suggested for her.
I patted her stomach lightly, as if I were rewarding a puppy. "That's a good little girl."
I got up off of the bed, and took off my robe, laying it at the bottom of the bed. Now naked, I glanced over at Bob and could see he was enjoying the show, as his penis was even more erect than before. I pointed at it, and mimed touching it, and then wagged my finger back and forth at him, indicating that he was not to touch himself. I know him, and knew he would want to start stroking himself as I played with my little pet.
As I sat back down on the bed, I asked Ruth, "Are you ready to continue your training, my sweet?"
"Yes, Mistress."
"Good. You just lie there and let your Mistress play with you." I started gently squeezing both of her nipples, which elicited a gasp from her. She settled down, and I began squeezing harder and harder, as the nipples became more erect in my fingers. I pulled them outward, elongating her breasts, and as I let them go, they popped back down to her body but her nipples were now bright red and grossly elongated, standing at least three-quarters of an inch off of her breast. Even though her breasts were not that big, her responsive nipples were quite impressive.
I went back to them and rolled them more gently between my fingers. They stayed at attention, and after about a minute of this I began to smell her arousal as her pussy became wet once again. Even though she claimed not to have had much experience with sex, she was clearly enjoying this stimulation.
After a couple of minutes of playing with her breasts, I shifted my attention downward and began running two of my fingers through her pussy, first just grazing her outer labia, but then adding more pressure and stroking her inner labia. My sense of smell had been spot-on; she was once again leaking like a busted pipe; her pussy, like her nipples had been before, betraying her state of arousal. I now dipped both of those fingers deep into her, and once again, she gasped.
"Quiet, my pet, or I will gag you," I warned. She quieted down again, allowing me to plunge my fingers in and out of her without responding verbally. After a dozen or strokes like this I pulled my fingers out of her. She started to object in frustration, but before a full word could escape her lips, she caught herself.
"Good girl, you're following instructions well. I have a reward for you." I took the two fingers that had a few seconds ago been deep in her pussy, and I pressed them to her mouth. She immediately opened, allowing me to put them into her mouth, and she closed around them. I felt her tongue swirling on them, tasting her own pussy juices, until the fingers were well cleaned.
I withdrew my fingers from her mouth. Shifting on the bed, I spread my legs and inserted the same two fingers in my own pussy, which by this time was wet once again from the teasing I had been inflicting on Ruth. I thrust them in and out a few times, the squishing sound quite audible in the room. I knew that Ruth must have recognized that sound, wondering what would be coming next.
After getting them thoroughly coated with my own juices, I proceeded to repeat what I had done earlier, bringing the two fingers to her lips, and waiting for her to open and accept them into her mouth. She did so immediately, and once again, cleaned them off with her tongue. As she did this, I leaned down and whispered into her left ear, "Do they taste as good as your own juices, my lovely?"
She nodded her head up and down as she continued to lave my fingers. After giving her enough time to clean them thoroughly, I sat back up and removed them from her mouth with a "plop." I saw her lick her lips, getting a final taste of my juices from there as well.
"I bet you never thought you'd enjoy another woman like that, did you pet? You may respond," I prompted her.
"No Mistress, I've never done anything like this with a woman before."
"Well, there's even more for you to experience." I shifted a little bit closer to her on the bed, and throwing my left leg over her body, I sat down on her chest just below her breasts. She seemed surprised by this action as her body adjusted to having my weight on her. I lifted my body just a bit, and leaning forward, I began to slide up and down, my very wet labia grazing across her belly from her pubic bone up to just below her breasts. I continued this for a few minutes, feeling my own arousal rise, and then glancing over my shoulder and down, seeing her own wetness secreting even more from her pussy. I could feel her breathing getting deeper, as she was clearly enjoying this sensation. As I turned back around again, I glanced at Bob, and saw that he was entranced by our act, staring down at my pussy as it dragged across Ruth's stomach.
I stopped the sliding, and still leaning forward, I lifted my body and slid just a bit more toward her face and to the right, dropping my wet pussy right on top of her left breast. I couldn't tell for sure being as wet as I was, but I thought I could feel her nipple pop right into my pussy. I could just picture it, being coated with my pussy juices, as I rotated in a very tight circle around her breast, allowing them to coat the entire surface.
After continuing this for a stretch, I lifted up again, and slid my pussy down her body, enough that I could now lean forward and begin to lick my own juices off of her breast. "Mmmm," I sighed, continuing along the outside of her breast and moving inward toward the nipple. "You're right, sweetie, my juices are absolutely delicious." When my lips approached her nipple, I sucked it into my mouth, and pulled upward, extending it and her left breast once again. As I tightened my lips so as not to lose my grip on her nipple, I heard her gasp once more.
I tugged her breast up and down repeatedly, loving the taste of my own juices on her firm, puckered nipple and her skin alternating between taut and loose as her small breast extended and retracted. I then let it go, slid back up on her body, and repeated the procedure on her right breast. Once again, I glanced over at Bob, seeing him still spellbound by the performance in front of him. I rubbed my pussy juices all over her breast, then slid back down and began sucking it and her nipple as I had with the other. As I did it this time, I reached between my legs with my right hand, and began stroking her labia. I was not surprised to discover she was just as wet as I was, and while I couldn't see it, I could just imagine her juices beginning to soak the bed underneath her.
After a few more moments I shifted my attention from her lips to her clitoris. Finding it hidden beneath its hood, I began to circle it with my finger. Just as with her nipples when they received my ministrations, her clit too began to expand as it responded to the attention being applied to it. I continued stimulating both parts of her body, until again I felt her orgasm was close. I removed my right hand, and sat back up, releasing her clit and breast at the same time.
Her body slumped back down at the bed, now being accustomed to my teasing her by bringing her to the precipice and not allowing her to fall over it. I chuckled as I saw her reaction. "Oh you poor thing," I said in a sympathetic voice. "It must be soooo hard for you to come so close to that release and not achieve it. You may speak, pet."
"Oh god yes, Mistress," she replied, the frustration obvious in her voice. "Plllleeeaaaase won't you let me cum?"
"Not yet, you'll cum when I say it's time," I admonished her. "Time for a little break." I got up off of the bed, and walked around it to Bob. I bent down and whispered to him, "Be a doll and get me some of that white wine from the mini bar. Being so wet I'm getting a little thirsty, so I need a cold drink." I took hold of two of his fingers and placed them between my legs, providing him an opportunity to see firsthand exactly how wet I was. As I did this, his cock bobbed up and down, attesting to how much he enjoyed the thrill. I took them away again, and nodded toward the living room. He got up and walked in there.
I walked over toward the full-length mirror on the wall of the bedroom, and glanced at my reflection. My nipples stood outward proudly, even though my large, 44D breasts sagged toward the floor. As I heard the sound of a cork being removed from a wine bottle in the next room, I glanced at the glistening of the juices on my public hair, visible even in the dim light of the room. While quite overweight, I was still pleased with my appearance and proud of myself. I know not everyone finds an overweight, middle-aged woman sexy, but I had learned that there were enough people, both men and women, who had cougar and BBW fantasies, that I could still get a rise out of them. I knew from Ruth's reactions so far that she was in that camp, even though I was almost twice her age.
After a minute of admiring myself, Bob returned to the bedroom balancing three wine glasses. He handed me one, and put a second on the night stand on Ruth's side of the bed, keeping the third for himself. I took a sip, the cool Sauvignon Blanc quickly quenching my thirst. "Ahhh," I sighed in satisfaction, "just what I needed."
I returned to the bed and sat down next to Ruth. I put my arms behind her shoulders and pulled her forward a bit, about as much as her cuffed wrists allowed. "Sit up here for a moment, my love." I reached over and grabbed her glass, and brought it to her lips. "Drink," I commanded. She complied, and as the chilled liquid hit her throat, she drank more eagerly, she too clearly parched from all of the fluids dripping out of her crotch.
"Thank you, Mistress," she said in appreciation.
