Harry Potter doesn't belong to me.
This takes place during the fifth book, right before Harry brings Hedwig to Professor Grubbly-Plank in the teacher's room.
"Minerva, I can't. I knowhow you fee, and I feel the same way, but with Umbridge around, it's just not possible."
"Wilhelmina, we are alone. I put a spell on the door so that no one can enter without knocking. Please, just this once, let us feel what we want to."
Professors McGonagall and Grubbly-Plank snuggled closer on the teacher's lounge couch. McGonagall had her head on Wilhelmina's shoulder, and she was peppering the other teacher's chin with frantic kisses.
Professor Grubbly-Plank turned slightly and started kissing Minerva's ears. She was starting to feel hot as they leaned back on the couch.
Minerva reached up and grabbed Wilhelmina's left breast in her hand. Through the robe, she started to rub excitedly. Wilhelmina, aroused by this show of affection, slipped her hand into Minerva's groin. With her index finger, she slipped into the slippery hotness of McGonagall's excitement. The two kissed and rubbed together more. They felt a subtle change in the tension of each other's body. Minerva, still rubbing on Wilhelmina's breast, reached her other hand down to Grubbly-Plank's groin.
With a groan, both women satisfied each other quickly. Then just as suddenly, they broke apart. Somebody was knocking on the door.
I know this was really short, but I needed and explination for why neither woman is married, and why Grubbly-Plank seems to hate men. Besides why else would two teachers with unrelated subjects be alone at a time where everyone else is teaching?
