Garden Song (слэш)

Ilya thinks about the last night they spent together, thinks about Shane splayed out on a hotel mattress pleading for his touch, thinks about how they hadn’t even kissed, and it starts as a strange little tickle in the back of his throat. Barely-there. He could ignore it if he wanted.
Then the intensity grows, flourishes into full-blow irritation, and suddenly he’s sputtering on his Coke and attracting the attention of the woman in the first-class seat across the aisle from him. He thinks it’s just some odd coughing fit, or that he inhaled his soda on accident, so he’s shocked when he feels something soft and smooth and triangular against his tongue.
It’s not until he spits the object into the napkin he’d received with his drink that he can see what it is: a long, thin, green leaf. A sepal.
As soon as Ilya realizes what he’s looking at, he’s flooded with dread.
