Offensive spells.

"We'll practice the Full Body-Bind Curse", you say. "Repeat what I say, and follow my movements."

You point your wand away from Neville.

"Petrificus Totalis!" you chant, moving your wand in the prescribed motion.

Neville tentatively repeats the spell a few times, until you're satisfied he's got the spell right.

"You've got the theory", you say with a grin. "Now, for the practice."

You and Neville stand opposite each other, a pile of cushions placed reassuringly behind you. You take it in turns to try to cast the curse correctly, or try to deflect it using a Shield Charm. You manage to get through Neville's the first few times. Each time you hit Neville with the curse, his arms and legs stiffen, and he topples back onto the cushions. After casting the counter-curse, Neville stands up shakily to try to curse you. Unfortunately for him, you are too fast with casting a shield, and his curse fails.

Finally, after fifteen minutes of practice, Neville manages to raise a strong enough shield to deflect your curse. His face glowing with self-pride, Neville raises his wand, and before you can shield yourself, casts the Full Body-Bind Curse. The curse hits you, and you feel your muscles freeze. You topple backwards, and land on the cushions with a thump.

"I'm so sorry, Harry", Neville says apologetically, hurrying over to you.

You roll your eyes at him, willing him to say the counter-curse, and free you. Neville bites his lip in embarrassment.

"I can't remember the counter-curse", he says.

Inside your head, you're screaming at Neville, reminding him of the counter-curse, telling him to find Hermione so that she can free him. Instead, Neville kneels next to you. He looks into your eyes, then quickly averts his face, probably because he's embarrassed that he can't free you. You glare a Neville, but he is now resolutely looking away from you. You close your eyes, trying to push away your anger at Neville; it won't help to get annoyed with him, and anyway, you can't express your anger to him now.

While your eyes are closed, you hear Neville moving around, and feel the cushions around you move as he does. You keep your eyes closed, resolute in your attempts to keep your anger down. Your eyes snap open, though, when you feel something in your leg. You can't see anything due to your limited field of vision, but you're sure that Neville is involved. You want to tell him to get off you, but can't. Neville's hand – you are convinced that Neville is touching you – rests on your knee for a moment, before slowly heading up your leg. You want to roll away, but the paralysis of the curse prevents you from moving. Neville's hand finally stops on your upper thigh, too close to your cock for comfort. It rest there, a warm pressure that you feel through your clothes. To your embarrassment, you feel your cock twitch. Although you hope that Neville doesn't notice your hardening cock, you don't have much hope of that. Your fears are confirmed when Neville's hand lifts suddenly from your thigh, and then after a few seconds, presses down lightly onto your cock. It twitches again, now half hard.

It seems that Neville is curious about your reaction to his hand. He presses down again, and then his hand vanishes. You only have time to breathe a sigh of relief, when you feel Neville fumbling with the zipper of your jeans. Your heart stops for a moment in your chest as Neville unzips your pants, and pulls down your underwear to expose your cock. While you aren't embarrassed about your cock – it's average length, and quite good-looking, if you can say so yourself – you can't help feel self-conscious when Neville holds it up between thumb and forefinger. Your cock, though, has no such qualms. Neville's touch sends a thrill through your groin, and your cock pulses, and becomes fully hard. You can almost feel Neville's eyes ogling your cock.

After a short time, Neville grips your cock, and begins to awkwardly jerk you off. He needs to adjust his grip a few times before he is able to stroke your cock with long strokes. A moan catches in your throat, unable to escape due to the Full Body-Bind Curse. When Neville lets go a few minutes later, your mind has melted; the feeling of a hand of your cock was so stimulating. A few seconds later, you feel something warm and wet on your cock, and you realise that Neville is sucking it. For a moment, you struggle with the curse. When you fail to break it with sheer will, though, you resign yourself to wait, and, although you won't admit it to yourself, enjoy the experience.

Contrary to your expectations, Neville gives a good blowjob. You don't know whether it's because he's a natural, or he has had previous experience, but you don't want to speculate. You don't want to imagine Neville sucking cock. This train of thought brings you back to the present, where Neville actually is sucking a cock, and not just any cock, but your own. His tongue grapes around your cock in an intricate pattern that eludes you. Neville's mouth bobs up and down onto your cock, taking it deeper than you would have thought possible, then pulling off so that the cold air is in stark contrast to his warm mouth.

When you finally cum, Neville swallows it all. He sits up, and tucks your cock back into your pants. No sooner has he done that, when the door to the room slams open, and someone enters

"Harry?" Hermione says, leaning over him, with a worried look on her face. "What happened?"

"We were practicing the Full Body-Bind Curse, and I got him", Neville explains, "but I couldn't remember the counter-curse."

Muttering with annoyance, Hermione casts the counter-curse, and you feel your muscles loosen. She pulls you up.

"I was looking for you", she chides. "You wanted me to help you with your Potions essay."

"Sorry", you apologise without feeling.

As Hermione drags you from the room, you look over to Neville, and blanche. In the corner of Neville's mouth, you can see a bit of you cum. Neville winks at you, then licks it up.
