Harry and Hermione were struggling to survive in the wilderness since Ron's departure. He had left them in a rage, seeking the refuge of his family. However, Harry and Hermione remained determined to find the remaining horcruxes, and were still in hiding, moving around the country regularly, camping in isolated areas. Tensions were rising between the two of them as they had barely escaped from Godric's Hollow with their lives after being attacked by Voldemort while in search of new clues at the home of Bathilda Bagshot. They had retreated to the Forest of Dean and set up camp, frustrated as they were running out of ideas as to where to find more clues.
Harry's wand had broken in the fight to escape, leaving them with only one wand between the two of them, therefore they had to take it in turns to keep watch outside their tent. They had every charm Hermione could think of protecting the area, leaving them relatively safe, but Voldemort had proven that he was more than capable of tracking them down no matter what protection they had. Hermione took the first watch outside the tent, leaving Harry alone inside. He tried to sleep on the low bunkbed but was struggling. He couldn't stop thinking, about their next move, how Ron had left, them and about how he felt about Hermione.
He had always thought of her as just a friend, but over the last few weeks he had felt increasingly physically attracted to her. It was just little things, like a certain look from across the tent, their eyes meeting for several seconds while she bit her bottom lip slightly, and it was starting to drive him wild with desire. Maybe it was the fact that he had seen very few other people for months, or the fact that they were bonding during their dangerous quest. He knew Ron had feelings for her, but he had selfishly left them, leaving Harry very little reason to feel bad for these strange new feelings. Whatever they meant, he found his mind wandering, imagining the two of them together, and exploring the possibilities in his mind.
Inevitably, these thoughts in his mind led his body to react. His cock became hard in his boxers, which was all he was wearing under the blanket. As he imagined the two of them together in his head, it throbbed and ached to be touched, leaking precum. He closed his eyes, slipped his boxers off and tossed them onto the floor, allowing his cock to spring forth. He seized it and started to pull on it, slowly and deliberately, as he imagined Hermione stark naked and riding him right there on the bed, he perky boobs swaying while she ground against him.
He had only glimpsed the more intimate parts of Hermione's body as they changed in the confined space of the tent, always accompanied by blushes and averted gazes, but he could not help becoming aroused whenever he saw a flash of her boobs or ass. It was these glimpses that fuelled the fantasy he was having now as his picked up the pace on his cock.
He wondered what position she would like to be taken best. Would she like to ride on top? Or would she prefer to be taken from behind, on her knees like a beast? Perhaps his lust would be too great to consider such things, and he would just mount her and take her on her back, pressing himself between her legs and fucking her roughly.
What noises would she make? Was she a moaner, a gasper, a sigher? Or perhaps she was a screamer. He thought back to his previous experiences, with Luna and Ginny, and the sounds they had made during their sexual exploits. He was sure he had heard Hermione moaning in her bed late one night, stirring him from a deep sleep only briefly. He was even sure if he had been dreaming or not, but it sounded like she had been pleasuring herself. It was these sounds that he imagined she would make as she took his big cock deep inside her wet pussy.
His mind wandered to the various fetishes he had. He hoped that she wouldn't mind that he liked to worship feet and would indulge him in his fetish. He had seen her feet on many occasions as she was not shy about going barefoot in and around their tent. Her feet would get dirty outside and she did not seem to mind, propping her dirty feet up while she read The Tales of Beedle the Bard for the hundredth time. He tried his best not to stare when she did this but could not help himself. He was sure she had caught him looking, smirking coyly to herself while she flexed her beautiful toes, crossing and uncrossing her legs. This never failed to get a rise out of his cock, causing exquisite pain that would have to remain until Hermione left the tent or fell asleep.
Any worries about being caught by Hermione soon evaporated. They could both die any minute; being caught masturbating was the least of his worries. He imagined worshipping her feet as he wanked himself faster, sucking on her toes, both as foreplay and while fucking her. He wondered if she would give him a footjob, imagining her massaging his big cock with her pretty feet until he could not stand the pressure anymore and emptied his balls all over her dirty feet…
Thinking of this was too much for Harry to bear and his cock erupted all over him, covering his chest in spunk. He lay on the bed satisfied, naked and covered in cum, panting in post-orgasmic bliss. He didn't know how long it took him to catch his breath, but by the time he did he had come to his senses. He stood up gingerly and looked for something to clean himself up with. Usually his post-wank clean up only required a wave of his wand, but without it he would have to wipe it off. He pulled a towel from under Hermione's bed and unravelled it. Something black fell out onto the floor as he did this. He bent down to see what it was and found that it was one of Hermione's thongs. He picked it up and observed it closely, and noticed that the crotch was stiff with the dried remains of her pussy juice.
His thoughts quickly moved on from cleaning himself to wanking off again as his cock grew hard once more with Hermione's dirty thong in his hand. He held the crotch up to his nose and inhaled her incredible scent, his cock becoming erect once more. He couldn't help himself, he just had to have another wank, and he took his cock in his hand once more. He carried on inhaling the wonderful scent of her pussy while working his slick cock in his hand.
