[This was a custom request] Hermione and her friends are seeking a Polyjuice potion. She comes to you, as you're one of the top wizards in your year, for some help. You don't have a polyjuice potion but you have just finished brewing a love potion. You've always fancied Hermione but she's a bit too straight laced for your liking, so you get an ingenious idea. You lie and tell her that you have her polyjuice potion right here. You encourage her to taste it - just to make sure that it works. She admits that that's probably a good idea so sip your love potion straight from the cauldron. After a few seconds, she looks at you with lust in her eyes and begins to tell you that she's always been in love with you. She strips out of her uniform, showing you her underwear and perfect, tight little body. She begs you to make love to her right now on the desk. Your cock jumps to attention. But you want her mouth first... you instruct her to wrap her little damp panties around your cock and suck it. She happily obliges, slurping on your hard length with an enthusiasm that only a girl in love would give. Before long, you need to feel the wetness of her cunt. So she climbs on top and rides you cock on the desk until you both cum. Your seed spills into her hot womb but your cock stays hard. You want to make the most of your potion and you know, under these circumstances, that she'll even let you take her sweet, virgin arsehole. She moans with both pain and pleasure as you slip into her arse - never before stretched by a big cock. It's a tight fit and it takes a while for her to adjust to your whole length. But soon she's sat on top of you with your entire cock eaten up by her arse. She begins to move on top of you once more - riding you with her asshole. She feels incredible. Inhumanly tight and warm around your aching dick. You buck your hips into her and she matches your strokes, riding you until you cum once more into her belly. Leaking cum from both of her holes, the potion begins to wear off and she suddenly realises what has happened. She's ashamed and quickly rushes to cover up her exposed body, calling you all the names under the sun for taking advantage of her in such a way. You know she won't tell anyone of this little indiscretion though - she's far too much of a "good girl" for that. You've had your way and no one need ever find out.
