Al and Severus were cute in a very Slytherin way. I particularly enjoyed reading their letters to Harry. This was yummy:
Snape snorted, stepped up, and pressed his upper body to Harry’s back. Snape’s hand came to rest over Harry’s on the knife, and Snape slowly cut the plant. Harry madly attempted to keep his breathing steady; his heart rate was a dead giveaway.
Snape lowered his head and his lips almost caressed Harry’s ear.
“Now, notice how lightly I hold the knife. There’s no need to throttle the knife, a nice light touch is all that’s really needed.”
Harry managed to not slump back onto Snape by sheer will power alone. Snape’s silky voice reverberated from Harry’s ear to his toes and then took residence in his cock.
