Read on G-Spells

You use the enhancement spells quietly before proceeding.

You gain your knowledge on G-spells and turns out(to your advantage) that they are non-verbal spells. You then read on how sensitive the G-Spell is and you can't wait any longer to try it out. You cast out,'Geesensitivius' and suddenly Hermione jerks. Her face turns red and begins to get sweaty. You felt the need to tease her more. You cast the spell again and this time you hear a slight moan from her. She then quickly bit her lip to stop herself from moaning furthermore. You then found a spell which makes her nipples erect. "Nippuserectus" you cast it in your mind. Through her robes, you can see her tits clearly. As you read on you found out that for maximum power the steps need to be repeated. You begin to use the above ways, again and again, her hair gets bushier and bushier.

Slowly and Slowly, bit by bit, she couldn't resist. At first, she hugged herself, legs crossed with occasional moaning. Then slowly she starts to unbutton her robes and pulled out her breasts. She started playing with them whilst closing her eyes. Her legs begin to ease out and she pulls up her robes till her waist. She starts rubbing her clit over her panties with one hand and plays with her nipples on the other. She then pulls out her wand and cuts through her panties. Feeling so sexually excited, she started lubing her wand with her saliva and began masturbating with the wand as her dildo. You then cast a spell which took her orgasmic limit higher.

Hermione couldn't resist any more. She wants a real human cock rather than a piece or wood(ironical isn't it?). She turns at you hungrily...
