As the orgasm finally receded, I was slumped in my restrains, trying to catch my breath. Even after the cold shower Sarah had given me, I could feel the heat radiating from my body. Sarah went back to massaging my legs and Peter was rubbing my back. It was heaven. Sarah began adding more oil to my back and butt, rubbing it all over. I could feel it start dripping down the crack of my ass.
Sarah's hands moved all over my glutes, massaging them and getting closer to my private parts with every pass. Soon she was between my legs, moving my clit around with the knuckles of her hand. I sighed, resigned for another wonderful bath of sensations. Her other hand was working the small of my back and began to move down towards my asshole.
With the help of the oil, Sarah ran her thumb up and down the crack until it was right on top of the opening. She massaged the oil around it, making sure that everything was coated with the lubricant. I started to exit the fog of pleasure while she was doing this.
"Sarah, what are you doing?" I sheepishly asked, it was as if speaking was going to break the spell. Peter reached forward and pulled my hair back.
"What did you call her?"
"Uh, ma'am? I mean ma'am what's going on?" Sarah didn't answer, but I could imagine her smirking. "Sir, sir, what are you doing? What's happening?"
"Ada." Peter said condescendingly "If you continue to speak out of turn, we're going to have to put the gag back. You don't want that do you?"
"N-n-ooo..." I trailed off
"Great! So, you can make all the noises of pleasure you want, in fact we encourage it. But nothing else. If you do as we say, we can make this next part a little easier on you." Peter paused, I assumed it was to see if I was going to speak out of turn again. I didn't fall for his trap this time. "See, you're getting the hang of it already."
Sarah, who had continued to massage between my legs the whole time, began to put pressure on my asshole. The pad of her thumb began to open my anus. Not wanting to anger the couple again, I started to make sounds of an injured animal, whining and panting. The couple just laughed and continued what they were doing.
Sarah's thumb started to make it's way into my asshole, which burned at the intrusion. The muscles spasmed around her finger, trying to push it back out. I gasped, continuing to make as much noise as I could without any words. The finger moved in an inch or so before retreating, giving me a moment's relief before plunging back in again, working the oil further into my hole.
As she was doing this, her knuckles were working my clit over, but it wasn't exactly pleasant. They stimulated me enough to work myself up, but not enough to go over the edge. Peter was still rubbing my back and shoulders, not paying any attention to what was happening at my back door.
The thumb moved in and out, pumping very slowly, allowing my anus to get used to the size. As soon as I felt like I could maybe take it, she moved further in. Soon she was using the entire length of the digit, rotating it once she got to the bottom of the stroke. Once she was satisfied, she plunged the finger in one last time and wiggled it around in my hole, causing strange vibrations in my body. I had never done anything like this to myself, so the sensations were foreign and weird.
Sarah removed her fingers and stood up to wash her hands. I could hear the sink running and her walking around the back of the bathroom. She was still wearing heels from before and the quick glance I had gotten of her before filled my head: black lingerie with straps crisscrossing her body. I heard her heels draw closer again and she resumed massaging my butt. I was going to melt at this rate, all the pampering it was getting. But she was focused again on my asshole. I was so disappointed, if they could just continue massaging me, I could almost forget they were holding me here against my will.
He hands were cold from the sink and I could feel goosebumps appear on my legs. She ran her thumb down my back again, stopping on top of my rosebud. She began to press in again, but I felt like something was off. Instead of staying the same width, her thumb felt like it was growing wider and wider. I couldn't help myself.
"What are you putting in me? What are you doing!?"
Peter laughed, moved to the back of the bathroom, and then appeared in front of me holding something in his hand.
"Do you see these?" He said, holding up little clamps in front of me. "These are nipple clamps. They attach to those little buds of yours and hold them tight. If you don't shut up right now, you're going to get the gag and the clamps. Understood?"
