Each spank landed on Kam's nearest cheek, accompanied by a satisfying slap, and almost immediately I saw Kam's eyes close as they pushed their butt out even more, inviting my hand, and from my angle I could barely see their butt but I could see their face, eyes clenched shut, and I watched them flinch and wince at each strike.
"Fuck..." Kam mumbled, then sucked their lips in, trying to silence themselves, and the excitement wouldn't stop disco dancing inside me. I tightened my grip on their hip and pulled them closer -- Kam stumbled a little in obeying, making one step towards me, pressing against my body, and now I could reach their further cheek, which I moved all my focus onto. Kam murmured quietly, a constant, everpresent note, thighs pressing tightly together, as I wondered how it felt to be so exposed with the cold air on you and, to my amazement, looked forward to finding out. Another strike, harder, my fingers pressed against each other so hard it hurt, broke Kam's lips open again.
"Ow!" they wailed, following it up with whimpers, hands refusing to leave the tree trunk. I let go of their hip, eager to regain my view of their exposed rear, and moved behind them again, throwing slaps at random cheeks, each sending a sear of pain through my palm and sometimes even up my arm, as Kam came to almost dance from leg to leg to ride it out. Their breathing was fast and heavy and I realised then that I was working to lure out the tears which had eluded me with the students. I wouldn't stop until I had them. More smacks came, keeping up the rhythm, not permitting Kam a moment's peace, as they suddenly let go of the tree and fell against it, their hands instead clasped to their mouth to keep their whines from getting too loud. These whines became cries, almost animalistic, desperate and pleading, muffled against their hand, and then I saw their back shudder and heard the first inklings of sobs drifting from them. I slowed, but didn't stop, each spank eliciting another shudder, and as Kam's hands left their mouth to hug the tree and fasten themselves to its trunk, they cried openly against the bark. I stopped.
"Are you okay?" I whispered -- I wasn't. My hand was killing me. Kam just nodded. "I'm gonna stop now." They nodded again, quietly sobbing, and I put a hand on their back, rubbing it gently. One of Kam's hands left the tree and grabbed my hand, squeezing it, as they stared at me with head resting against the trunk, eyes full of tears and breathing painfully, trying to fight off the sobs.
"I'm sorry," I said, quickly. "Did I go too far?"
"I told you not to say sorry," Kam whispered through the tears, smiling weakly at me. "Green." I smiled back and squeezed their hand too, as they stood there, bared and shaking and a little bit pathetic. "Oh, this is so embarrassing." Slowly, Kam pushed themselves up from the tree and put their hands on their butt, feeling it, wincing again.
"How is it?" I asked, as Kam turned towards me, darkness concealing what hid between their legs.
"Burns," they replied, gripping their cheeks, flinching at the pain but doing it again, anyway, before reaching slowly down for the waistband of their boxers and pulling them back up to cover themselves, their jeans following. The flaps of their dungarees stayed undone and hung loosely either side. "I feel so sorry for the students who get sent to you."
"Well..." I said, quietly, as Kam regarded me, "I think I've set myself up for a bit of a fall, here," and they nodded in a way which made me realise nodding could look evil.
"Oh, my revenge will be so sweet," they whispered, wiping at their face.
"Yeah?" I asked, excitement crescendoing in my belly.
"Oh, yeah. Put your hands against the tree and don't move for anything. You got that?"
"Y... yeah, I got that," I said quietly, turning and copying, leaning against the tree with both hands holding its bark. I felt Kam's presence behind me, as their hands came to wrap around my waist and reach for the buttons of my jeans. Inhaling deeply, their whole body pressing against my back, I felt my jeans loosen as the first button unhooked, then Kam's hands effortlessly, deliberately slowly, undid the rest.
"Let's see what you've got hidden under here," they muttered into my ear, before sinking below me and, gently, slipping my jeans down my legs. The cold air hit me at once, making me fidget, splashing over my bared thighs, as Kam pulled my jeans all the way down to my ankles.
"I only pulled yours to your knees," I mumbled, acutely conscious of my exposure; I'd worn plain black briefs, as far as I could remember, but in this position I could have worn anything or nothing and I'd have felt just as on show.
"I know," said a pleased voice behind and below me, and I knew they was staring at my butt just as I'd done to them. "You've got such a nice bum."
"Do I?" I mumbled, and I shivered as Kam's hands unexpectedly gripped my thighs, tightly, trying to draw out a gasp which I refused to provide.
"Definitely." Then, I felt their cold fingers slip under my underwear's waistband, trailing beneath, toying with me, then pulling them away from my skin, ready to peel them down. Suddenly, my whole body erupted in hot panic -- I forgot everything, all at once, except a furious need to get away.
"Wait!" I cried. "Red! Red!" Kam's hands left me instantly -- I felt their presence grow behind me as they got to their feet.
"What's up?" they asked, sounding concerned.
"I've never..." I whispered, still trying to make sense of my reaction even to myself. "I've never let anyone see me like this before."
"That's okay!" said Kam quickly. "I don't have to -- I'm not gonna do anything you don't want. Promise. You're not a student." I hissed out a note of laughter, my breaths itchy in my throat, and felt Kam's presence grow as they stood up behind me and leaned close to my shoulder. I felt their arms wrap around my waist and hold me tightly. The sense of safety started to prevail again. I felt ready again. "Do you want me to stop? We can go, if you want."
"No, I..." I took a deep breath. "No. I'm all yours." Kam grinned with delight and, to my eternal surprise, leaned past my shoulder and kissed my ear. My whole body shivered and they sank back to their knees, their fingers went back under my waistband, and by the cold air I felt my butt be exposed as they pulled them down. I felt my underwear drop down my thighs to my knees, stay there for a moment, then fall all the way to my ankles with my jeans, as Kam murmured in approval at their unwrapped present. I pressed my thighs together, instinctively, my hands shaking uncontrollably, already feeling tears coming, but not feeling the humiliation I expected -- no, I felt something else. Some sort of longing for it to keep going and a sadness at the knowledge that it might end. Damn it, Cherry was right, I am a sub at heart, aren't I?
"Ready?" came a whisper.
"Green." Kam didn't hold me as I'd held them, instead standing on their knees, enjoying the view I suppose, and throwing their open palm at my cheeks, alternating as I usually did. I hissed at the first strike, embarrassed to have caved so quickly, but held on as more smacks came, each one surely harder than any I'd given Kam. Their promised revenge was upon me. I whined and whimpered with my lips sealed shut, trying to ride it out, trying not to let escape the noises I was holding, as a feeling of liquid burning rose and swirled between my legs which I was desperate to reach down and relieve. Or for Kam to relieve. It was this feeling which made me keep going, keep riding the pain, as it built and built and built and every time I thought it would plateau it only grew in strength. Kam kept smacking, each one now coming with a grunt of exertion, or pleasure, or something, and finally my lips broke open and I cried out -- but, as I did, I felt something burst between my legs too, my back arched completely involuntarily, and I was looking up past the treetops at the empty black sky and crying out as my legs shuddered and, an awesome warm wave crashing over me, I climaxed desperately. My legs gave out from under me and, still holding the tree, I fell onto my knees, breathing heavily, a glowing warmth between my thighs, whimpering against the trunk,which isn't a sexy word but it's all I've got. I felt Kam's eyes drilling into me.
"I'm sorry," I whispered, my eyes shut, my whole body shaking, aware of my continued exposure as I sat on my knees, and I felt Kam get closer before they wrapped their arms around me and pulled me into a tight hug.
"Don't say sorry," they whispered, "that was amazing. All of it. Oh my God." I opened my eyes, my breathing still tricky to control, and turned to see Kam's face close to mine, close enough to see even in this darkness.
"I had no idea I'd react like that," I whispered.
"I was close, too," Kam said, quietly. "So don't worry. Maybe I will, next time."
"But you're ace."
"Stuff like that ain't voluntary." They grinned and leaned in to kiss the side of my head. They smelled of pinecones -- we were, to be fair, in the woods, so maybe that was just the woods.
Eventually, having forgotten any semblance of modesty in the raging afterglow of my orgasm, I was able to get to my feet and dress myself, before we scurried out of the woods and back onto the path. There was nobody around and we hurried back to Crownbird, parting ways at Lady McQueen House.
"Well," I said, looking up at the building, my butt burning under my jeans, still twitching between my legs, "this is me."
"Yeah," said Kam, looking up at it with me, and for a moment I thought I was going to invite them in -- but it was late they were still ace. We parted ways with a hug and, limping more than a little, I went upstairs, past a group of partying students in the kitchen, and collapsed onto my sofa.
