I still wasn't sleeping well after my experience of seeing the ground rushing towards the three of us in that little plane, and it put a damper on my sexual adventurousness for a couple of days. However, I was looking forward to starting a new pose at the life class, wondering which part of me the Professor wanted the class to focus on.
Bill and I headed off that evening, and I left him when we got to the building. He went to join up with Peggy and the rest of his class, while I went to the changing room that opened on to it. Changing was a bit of an exaggeration, because I was only wearing slip-on shoes, and a loose cotton smock, and I'd hardly had time to slip them off before the Professor came into the room.
"Hi Prof. What pose do you want me in this time?" I asked.
"Well ... um ... Jo. Remember the Courbet and the Schiele when you auditioned?"
The Courbet painting was of a woman lead on her back, one leg off the side of the bed, and her face hidden under one arm, but it was the Schiele I remembered, because it was a similar pose, but with the woman pulling her labia wide open. A shudder went through me, as I remembered the fear and thrill the first time I'd let a stranger look at the full glories of my open cunt, and how I'd ended up fucking myself with my car's gear stick afterwards.
"Yes? Well, I think the Schiele is a bit much to ask, but ... um ... I was thinking ... um ... maybe you could get you labia to stay apart, so everyone can see inside your ... um ... vulva, but you could still keep your face covered."
Oh fuck, could I really let the whole class, still strangers except Bill and Peggy, look up my hole? My blood was pumping adrenalin around me, making me tremble, while at the same time, the thought of it made me tingle all over.
"Fine, Prof, let's give it a go then."
I followed him into the classroom, getting the usual thrill at letting everyone see my naked body, and I lay back on the bed, my head hanging over one end, my legs apart, with one dangling over the other side. I knew everyone could see the full length of my slit, and I used my hand to try to pull my lips open so they could see up inside.
"How's that Prof?"
"Well ... um ... I'd like you ... um ... a bit more open, Jo."
A wicked thought flashed into my mind, and my mouth spoke it, even before my brain realised just how wicked it was.
"Alright, Prof, why don't you arrange it me how you want? That way, you can make sure it's the same next time."
I heard a sharp intake of breath from him. "Are you sure you don't mind, Jo?"
I said no, but it was only as I felt his fingers touch my cuntlips that I realised quite how wicked this was. I'd had some pretty way out experiences, but a shudder ran through me as I realised that it was one thing to show pussy to the class, but quite another for them to see their Professor pulling my cunt open right in front of them, my husband included.
God, it felt the dirtiest, most shameful thing I'd ever done. I mean, what sort of woman would let a stranger pull her pussy around so that a group of strangers could look up her hole? I was disgusted with myself.
The problem was, though, that it was also one of the most intensely thrilling things I'd ever experienced. I caught the waft of my scent. I knew from the smell that cum must be pouring out of me, which was confirmed by the soft sound like Velcro being pulled apart as he separated my labia with his fingers. I had a vivid image of threads of white goo, taut across my vagina. I could see the bulge in the Professor's pants, and I knew that had we been alone, I couldn't have stopped him fucking me, and nor did I want to.
With my head over the back of the bed, I couldn't see the class. That didn't stop me imagining all of them staring, amazed for sure, disgusted probably, excited hopefully, as they watched the Professor's fingers pulling my cuntlips apart right in front of them, each time letting them see up into my vagina, repeating it until he managed to leave it gaping and open.
I desperately wanted him to touch my clit, because I wanted to come, and was sure even the first touch would send me over the edge. It would be fun to come in front of Bill, but yet it struck me that it would be a very unprofessional thing for a life model to do. It took me all of my determination to force myself to wait until the class was over, and just to lay back and enjoy knowing that the whole class could now see deep into my cunt.
Maybe it was my lack of sleep, or the pose of laying on the bed with my arm over my face, or just my imaginings of what the class were thinking about seeing right up inside me. Probably the combination, I guess, because I must have dropped off to sleep, sleeping right through the break, because the next thing I was conscious of was something sliding up inside me.
It took me a while for my brain to catch up where I was, and I kept still as I tried to work out what exactly was happening. I slowly lifted my arm, and opened my eyes part way. I could see that the class had left, all except the Professor, who was standing at the edge of the bed, his erect cock sticking out of his pants being stroked by his left hand, while the fingers of his right hand were pulling my hole open, then pushing deep inside, before being pulled out again.
I'm sure you'd agree, it was too good an opportunity to miss, wasn't it?
"Why don't you just fuck me, Prof? Shove your cock up my cunt instead of your fingers. I know you've been dying to do it since you auditioned me."
He pulled his fingers out of me, but for a few moments, I didn't think he was going to do it. Then I heard a second voice, in a loud whisper. It was Bill, of course.
"Go on Prof. You could see she was gagging for it earlier. I mean, what sort of woman would let you pull her around in front of us all? She's just a fucking slut. You take her cunt while I use the hole at the other end. You don't mind, whatever your name is, do you?"
He knew I didn't, of course, but I'd only just got my mouth open to answer, when Bill rammed his cock right down my throat, at the same time as I felt the Professor's cock forcing its way into my slippery cunt.
Oh God, it was so good to feel the Professor's cock pistoning in and out of me, while my husband, who as far as the Professor was concerned was also a stranger to me, was fucking my mouth hard. And when I say hard, I mean it. Bill had rammed his cock deep into my throat, leaving his balls and pubes against my face. I couldn't help gagging at first, but I'd had plenty of practice with the delivery guys, and Bill had learned from that just how far he could go to turn my mouth into a tight hole to get him off, while still leaving me enough air to breathe.
He'd watched me get fucked before, of course: the time with the janitor, and I'd told him every detail of the cocks I'd had in me in Chicago, and the experiences in the sex shop and that wretched little aeroplane. However, this was the first time he'd seen be being screwed while he fucked another of my holes at the same time. It was a wonderful sensation, my entire being buzzing from having sex with my husband and another man at the same time, their two cocks deep in my body.
I just hoped he was getting a good look at the Prof's cock tearing my pussy apart, disappearing inside me. In any case, he was also squeezing one of my tits, while the Prof was working the nipple of the other one between his fingers and thumb. I could see the fixed stare on his face as he watched Bill's cock fucking my mouth, but I knew he was focussed on the stimulation my cunt was giving his dick as it went in and out of me like crazy.
I knew he was never going to last, having fantasised about me for weeks, his fantasy now having come true. He was in me, and going to shoot his spunk as deep into me as any man ever could. I was enjoying the spit-roasting as much as him, so I could forgive him not paying as much attention to me as he should, and I used my own hand to rub my clit, getting hit against his pubes with each massive stroke.
The situation must have got to Bill as well, because I recognised the signs: the taste of his precum in my mouth, the tightening of his ball sac, and the pace of his strokes, pulling almost right out of my mouth, letting me catch a breath, then driving his cock past the back of my mouth and into my throat.
"Come right up that dirty cunt that the whore loves showing everyone, Prof. Fill her fucking hole with your cum."
I guessed that Bill did it partly to excite him, but as much to make sure that he didn't fill my mouth with spunk too long before the Prof filled my vagina. Of course, it worked on me as well. I did, I really did love people seeing my naked body, and my cunt more than anything, so as I felt the Prof's short strokes and the twitching of his cock as he jetted his sperm into me, I came.
I guess Bill was going to come anyway, but as the Prof and I jerked around as I took his spunk into my vagina, Bill shot his seed straight down my throat, making me struggle to swallow it without choking, as my climaxing body sought oxygen.
As I came down from my orgasm, I guess I was expecting Bill to point out that I was his wife, though I don't quite know why. Would it have made me seem any less of a slut that the cock in my mouth was my husband's, while I was letting the art teacher fuck me? But he didn't. It was the Prof who pulled away first, looking a bit guilty as he realised what he'd done. He stuffed his limp cock into his pants, then went to the changing room to get my dress and shoes.
"You'd better get dressed, Jo. The janitor will be around soon to lock everything up. And you ... uh ... sir," he said handing me my dress, and dropping the shoes on to the floor. "See you next week, I hope?"
"Yeah, don't worry ..." I started to say, but the Prof had already shot out of the classroom.
