ECLIPSE (1/3)

Jonathan gets excited just from hearing the plastic flip-flop slapping of don Fernando Gravina's feet, his Master, approaching down the hallway.
- There's less than an hour left. Is the champagne cold yet? - his Master asks...

Gravina is a 54-year-old physics professor, somewhat heavyset and with gray hair. He also shows a white pelt of hair surrounding his nipples and covering his chest down to his belly. His legs have gradually lost hair over the years but are still not hairless.

He appears in the living room, freshly showered, wearing only a black jockstrap and flip-flops that he makes slap loudly as he walks. He knows Jonathan's skin prickles just from hearing the sound of them around him.

- Yes, my Lord, I put it in the freezer and then moved it up to the fridge. I also have something prepared to nibble on - Jonathan does not look him in the eye. It is forbidden to him. But he doesn't mind. He is happy without taking his eyes off his professor's feet and flip-flops.

The professor is the coordinator of the university's astrophysics department and Jonathan's thesis advisor. Jonathan is one of the best students in his class. For reasons not only academic, but because of something that bound them from the very first class, don Fernando felt increasingly drawn to the admiration Jonathan showed him. He never took his eyes off him during class, until the day the professor caught Jonathan, sitting in the front row, touching the bulge of his trousers, and he himself had to sit down, shielded by the desk, to also hide a most inconvenient erection, being a teacher in front of a large group of students.

Days later, Jonathan went to Professor Gravina's office to give him the reference for a couple of scientific articles about black holes.

- But they're in English, of course - the professor said, and then lied -. My level isn't that good, we could read them together. Surely you, Herranz, have a more up-to-date vocabulary.

- That would be the least of it, Mr. Gravina - assured Jonathan, whose eyes lit up.

- For now, - Gravina went to the door and locked it - it's this black hole that I would most like to observe right now.

Gravina began to massage Jonathan's buttocks. Jonathan closed his eyes and didn't move. A moment later Gravina set about rubbing his thumb along the center of his student's ass, pressing hard, as if he intended to tear the fabric and push it between Jonathan's prominent buttocks, squeezed by his tight jeans.

- That thing you're hiding in there is also of no small scientific interest, Herranz.

- Excuse me, it's Herráez - Jonathan dared to point out in a low voice.

- What difference will that make - Gravina began to unbuckle his belt -. Listen, Herráez: you will recall that in my classes I have referred to the subject of primordial nucleosynthesis and that it is still full of questions to be analyzed.

Gravina, positioned...
