We had been back on campus for about a week when Jess told me she wanted me to go to a party with her. A professor at our school had just published his latest book and was holding a release party in his home.
His house was what you'd expect from a tenured professor. Three stories, all wood, with books everywhere. Professor David Jensen was a big celebrity, often appearing on cable news shows, so the party was well attended. His glamorous, much younger wife, Rebecca was a big socialite in town. There were all sorts of rumors about how they got together, focused largely on her having been an undergrad and him having been her professor.
I guessed she was about 40 and he was in his mid-sixties, so pretty scandalous, I guess. They'd been together since then, so it appeared to have all worked out. They even had a daughter, Ainsley, who was about our age. She was in town for the party and something struck me the moment I saw her- there was more than a passing resemblance between Ainsley and Jessica.
After some time mingling, Jess grabbed my hand and guided me towards the stairs. "Come with me," she whispered. We went upstairs to the third floor. It was a den with leather couches and even more books. There was single door in the room which held a small office. I guessed that this was the professor's and as he stepped out from the door my suspicion was confirmed.
"Took you long enough. I was afraid you weren't coming up," Professor Jensen said to my fiancée.
"Are you kidding? It's the whole reason I came to the party," Jess replied to him and shot me a devilish look.
Suddenly, Jess dragging me to this party made sense. She was going to fuck him in his own house during his party.
"You must be Darren, the fiancé. Pleasure to meet you, but I'm afraid our window might be a little too short for pleasantries," he said, shaking my hand despite my stunned expression.
"Sweetheart, be a dear and keep watch out for anyone while I give the professor something he's long wanted, ok?" Jess said, giving my cheek a quick kiss.
I flushed red as the professor gave me a knowing grin while he took Jess's hand and led her into the office and closed the door behind them.
I stood there for a bit not really comprehending the surreal situation. I loved how dirty her mind was and screwing a sixty-year-old professor while he had a house full of guests was so hot. So she had set me up to not only know exactly what she was doing but put the pressure on me to play lookout.
I moved up to the closed door and I heard some muffled talking and movement. Were they undressing? Thinking about what they might be doing but not knowing for certain was intensely erotic. I stood with my ear to the door but my eyes towards the stairs. My heart was racing. What would I do if someone came up the stairs? How would I keep them out? Had they locked the door or was I the only thing between them getting discovered?
Then I heard Jess moan. It was faint, but I had certainly learned the sounds of her moans through our experiences together. My best guess was that the professor had begun going down on her. I realized my own dick had gotten hard which really made me fear someone would come upstairs. I wondered how would that look- me standing in a private room in the house with an erection while moans came from the office.
I heard what sounded like the best effort by Jess to muffle an orgasm. I noted how fast that had occurred, so either he was really good or she was very turned on by the situation. Perhaps a little of both. Then the sounds from the other room quieted down.
I couldn't help myself. I had to see for myself. I tried the door and found it unlocked. Fortunately it opened soundlessly. And then I saw them.
They were stark naked, as if clothing was an insult to what they were doing and they had no care in the world about being caught. He stood before her, his old wrinkled body illuminated by the sunlight coming through the window near them, and she was on her knees before him. Seeing her gorgeous youthful body so submissively prostrate before him and his not that impressive manhood caused me to shiver.
That's when I heard it.
A creak on the stairs below told me someone was coming.
I closed the door as quickly and silently as possible. Then I did my best to get between the stairs and the door to the office while at the same time hiding my erection. This had me behind a couch which certainly would be an odd position to be in so I grabbed a book and opened it as if I was reading.
Coming up the stairs was Ainsley, the professor's daughter. Again, seeing her was jarring as her resemblance to Jessica was pretty extreme. Red hair of a similar shade, although Ainsley wore hers longer. Their cheekbones and smile were also eerily close. And then it hit me- the professor was into this BECAUSE Jess looked like his daughter.
I shook the thought out of my head as I knew I had to act fast.
"Oh, hello there," I said, trying to act casual.
"Oh. Umm, hi?" she said, obviously confused.
"You're father, ummm, recommended this book."
"Oh? Have a stirring interest in the Socio-economical situations following the Second Boer War?"
"Oh. Oh! Y-yes. Sure. Of course. Who isn't?" I replied unconvincingly.
"Have you seen my father? Someone said they might have seen him come up here," she said glancing at the closed office door.
"Ummm, no. I've been here for a bit and I-I've not seen him," I lied.
I could tell she didn't really believe me. And then she started going towards the office door.
"Whoa, ummm, hey... Ainsley..." I stammered, putting myself between her and the door. Thankfully, my erection had faded enough it wasn't obvious. "So where- where to you go to school? I didn't catch that before..."
"We didn't talk, so not sure how you would've 'caught that'. I'm at Wellesley," she said, looking at me incongruously.
"Ahhhh... Wellesley. It's a... it's..."
