It was the sound of paper and a gentle swaying of the bed that woke me up. I opened my eyes and saw Prof Laufer leafing through a university report. That was the sound of paper. The gentle swaying was Cathy's head going up and down over his cock.
I was on the left side of the large king-size bed in a hotel in Birmingham, where Prof Laufer was attending a conference. And, as usual, he had brought one or two of his students along to taste the atmosphere of an academic conference. That was of course the idea.
Reality was, that he had brought both me and Cathy, a student one year ahead, along not to taste academia, but something entirely different. That was happening right now in front of my eyes.
Prof Laufer noticed me opening my eyes. A quick movement of his head indicated what he wanted me to do: join Cathy sucking his cock.
It was not the first double headed blowjob I would be giving him. I knew his rules, most importantly: no hands. He liked tongue and lips only. And he liked it with multiple girls at once.
Cathy was just working his shaft, gently licking it up and down. She was of course fully naked, her breast swaying along as she licked. Occasionally her tongue would flip over the top of his penis before making its way down to his balls again. Cath licked up and down and Prof Laufer flicked through his paper.
I edged closer to them and my tongue made contact with the top of his penis. I circled it a few times. Then I took it in, still rotating my tongue around its head. I took it in a bit deeper, then up again. Main rule: no hands. Meanwhile, further down, Cathy was licking his balls.
For us girls in his study group it was a strictly no hair policy. He expected us to be cleanly shaven at all times. "My little nymphs", he used to call us, when he was in a good mood. But his own rules did not apply to him. He still favoured the all hairy look.
Cathy licked his shaft upwards and our tongues met, french kissing with his helmet between our tongues. We both went down his shaft, one girl on each side, then up again, our tongues entwining when we reached the top.
Then Cathy took possession of his helmet while I went down his shaft to his balls. I licked them gently, twirling my tongue around one and then the other before gently lifting his scrotum up and licking it from behind.
Between us girls it was a silent competition. We all wanted to please him so he would reward us with better grades, invitations to conferences or arrangements for internships. But as favours were often withdrawn without notice. That made us forever obedient to him.
I knew how much Prof Laufer liked a good piece of ass, so when I sucked his cock I always made sure that my backside was in full view for him. Sometimes he would take his hand and gently touch my ass, sometimes he would ease a finger into one of the holes or even pull my whole back over for some 69. But today there was nothing of it even though I tried to spread my cheeks as wide a possible. The more he rejected me, the more I tried to please. At this point he could have asked me anything, but he didn't.
