I loved this! It was hilarious, great job.

A marvellous, quite distracting, story. The last 3 sentences moved it from good to excellent

Brilliant, what a gem! You had me glued to the screen and couldn't help grinning. :-)

Poor Sev, he really didn't need to feel such performance anxiety, I'm sure that she was pleased with his superb equipment, especially since it only took 2 thrusts for her to come. I hope they both lasted longer the next afternoon, 2 thrusts would be far from enough for me.

From your description of her scent, I'd say she was wearing Coco Mademoiselle or Organza Indecence. I love them both, but the Organza Indecence has been discontinued. There have been a multitude of protests about that , but I am using mine sparingly until Givenchy puts it back into production. You must be able to tell from this that I am a perfume freak.

This is absolutely, wonderfully hot!

You know, I never thought I'd really like a relationship between Severus and any of the other Hogwarts staff, but you've just proven me wrong. I think this is one of the best "Severus' First Time" fics out there. Well done.

Fans self vigorously-lovely smut, thank you!

I would love to see a sequel to this

Professor Sinistra and Severus -- interesting, indeed. A pairing I had never considered before (mainly because Sinistra is not on my radar at all) but all the more fun because you can invent whatever you'd like as you go along and have it still be perfectly plausible, which this is. A lovely little romp. Severus is so charming as a virgin. I'd gladly trade places with Sinistra. ;-)

Loved this:
Her eyes widened a little at the none-to-subtle bulge of his erection pressing against her through the fabric of his trousers. “Oh ho…” She cocked an eyebrow. “Perhaps not so honest after all.” She made a small clucking noise with her tongue and feigned a bit of a pout. “Here you were making me work so hard, and yet you wanted it all along…"

This part:
“Stop thinking…” she whispered against his lips. “I can hear the cogs in your head whirring, Severus, and it’s most distracting.

... was very masterful because having just read what preceded it, I got the distinct impression he was too busy thinking and not busy enough doing. And then Sinistra says the very same thing and I felt guilty as a reader, too, because I had been "drifting off" while reading Severus' thoughts! Nice work as always.
