Caviar and Lamb (Mature erotic story)
The most seductive thing about Nathalie was the fact that she was utterly forbidden. She was a first year undergrad at my college, and I am a married man, dependent on my job and in deep shit if I should lose it. The consequences on my part were about as serious as they could get were I to be caught in a compromising situation with one of my students. But, as I say, that was the most seductive thing about her. The devil on my left shoulder kept whispering in my ear all the way through that first semester, and I was experienced enough with female undergrads to be able to distinguish the merely flirty from the serious propositions.
