In his perverted state he searched under Hermione's bed, hoping to find more of her underwear to inhale. He found a forgotten pair of her socks up against the canvas wall of the tent. His cock pulsed in his hand at just the sight of them. He pulled them from beneath the bed and held them carefully. They were white cotton, but had seen better days and were slightly stiff from her sweat which had dried into them. Their soles were darkened, leaving a grey outline of her pretty feet on them.
He observed them closely while, letting go of his cock just long enough to hold them up to his face. He covered his face with them, soles down, and inhaled the sweaty aroma of Hermione's dirty feet. He held them up to his face and rubbed them against it, allowing the stink of her feet to cover his face. He grabbed his cock once more and wanked it hard, the dirty socks sending him into a frenzy of desire for her.
Another perverted thought crossed his mind. He stopped wanking just long enough to take one of her socks and carefully placed it over his cock. The rough cotton felt good against the exposed head of his cock. He held it onto his cock and continued to masturbate, enjoying the sensation of the dirty sock on his cock. He continued to sniff the other sock, intoxicated by her scent. He thought about her feet, about all the times he had stared at the, aching to touch them, to smell them. Even if he would never get any closer to the real thing, this was close enough. He fantasised about kneeling before her and sunk to his knees as he imagined worshipping her dirty feet once more. He ached to lick her soles and suck her toes, cleaning them with his tongue until they shined.
He finally couldn't stand the pressure in balls any longer. He pulled on his cock faster and faster, finally allowing his spunk to erupt from his cock into Hermione's sock. He gasped in pleasure, on his knees, bucking against her dirty sock as he milked another load of cum from his balls.
He stood up in the tent and stood there naked, the sock still on his cock. He pulled it off, a trail of spunk connecting it to the end of his cock. He hastily put the socks bag together and pushed them back under Hermione's bed, along with her thong. He used the towel to rub down his previous load of cum of his chest and tossed that under the bed too, covering the underwear.
Harry was just about to put his boxers back on and get back in his own bed when a small vial caught his eye in the corner of the tent. He walked over and stooped to pick it up. He recognised it as polyjuice potion, then it hit him; he could become Hermione and explore her body first-hand. His mind immediately flooded with all the dirty acts he could perform whilst in possession of Hermione's body. Ordinarily he would not behave in this manner, but these were no longer ordinary times.
He knew he may never get another chance, so he searched Hermione's bed for one of her hairs. He scoured the sheet until he found one; a small curly one undoubtedly one of her pubes. He opened the vial and dropped in the hair. The potion turned a shiny silver colour, gleaming in the low light of the tent. He lifted it to his lips and drank the whole thing and allowed it to take over his body…
