Summer at the Grangers

You consider your options for a second. It's really tempting to ask her to get on her hands and knees if only to satisfy your curiosity. You remember the glimpse you got of her anus and you would really like to see it closer but you know you'd be tempted to at least touch it. She seems really uncomfortable with that option and looks like she only added it for your benefit and even if you would never go against her wishes in something like this touching her there might give her the wrong impression, that you are trying to force her or something. No that won't do at all, it's her turn to feel good too.

You sit on the bed and pat your lap giving Hermione a reassuring smile. Looks like that manages to calm her nerves and she walks up to you turns around and parks her butt on your lap. You two squirm for a bit trying to find a comfortable position. She spreads her legs and slides her butt forward a bit to give you better access to her pussy and your already hardening member ends up between her butt cheeks. She also slouches a bit so your chin rests on her shoulder.

Your hands, that at first go instinctively to her hips, begin to roam. Your right hand runs through the patch of hair that got you so intrigued a while ago to find that yes, her hair down there is quite soft. The left caresses lightly her cute bellybutton before moving up to her breast. You can feel her heartbeat under your palm and it speeds up when you accidentally tweak her nipple as you are kneading her tit.

"Harry, I haven't told you how to do it yet." She says putting her hands over yours holding them in place.

"Sorry, please tell me what to do, Professor Granger." You say teasingly. You hear her give a small gasp that you wouldn't have heard if you two weren't so close together and feel her heartbeat that was starting to calm down speeds up again.

"Ahem, very well, since your hands will be busy during my lecture you are excused from taking notes mister Potter." She says in her best teacher voice. "We will begin with the erogenous zones. They are divided into three categories, primary, secondary and tertiary. We will 'touch' them from the less sensitive to the most." She says and you give a little snort at her pun. "The tertiary erogenous zones are those that normally wouldn't be associated with sexual stimulation but some people find stimulating nonetheless. In my case I like my earlobes and the part of my neck below them to be caressed, kissed or nibbled lightly." You turn your head and proceeded to do exactly that.

"Like this?" You whisper in her ear and feel her shiver in your arms.

"Yes, just like that." She answers in a breathy voice.

"Can I ask a question?" You say before going back to nibbling on her earlobe.

"Yes, of course." She says, trying to get her serious tone of voice back.

"That was rather specific, I mean, it's not like someone is going to do it on accident. How did you find out that you liked it?" She hesitates for a few seconds before answering.

"Julie. She helped me with the practical part of my sexual education and experimenting with what I like and what I don't, It was when I entered puberty back before starting at Hogwarts and every summer since." You picture in your mind the kind of help she's insinuating that her sister gave her and your penis stiffens against her butt.

"But I thought you two didn't get along, I mean, when I got here..." You trail off remembering Hermione's scowl as Julie climbed the stairs.

"She can be exasperating sometimes and she ignores the meaning of personal space but her heart is in the right place and I know she loves me. Not like that you prat." She adds elbowing you guessing right what you were thinking. "Let's just's say that my relationship with my sister is complicated and leave it at that. Can we go back to the lesson now? "

"Yes, yes. Sorry."

"Okay, as I was saying. Another one of my tertiary erogenous zones is my stomach." She says bringing your right hand up from her pubis and making you trace random patterns with your fingers. "I prefer light touches or lightly racking your nails all over it. This is an example of how doing the same thing in the same place can give different results, if I'm already aroused it excites me more, but doing this after an orgasm kind of relaxes me."

You humm as you continue to caress her belly.

"Next we've got the secondary erogenous zones, unlike the tertiary these are better known for being sexually stimulating without being the sexual organs themselves. These areas include the groin, the area located between the hip bones, between the belly button and pubic bone, inner thighs," As she's naming the different parts of her body she pauses for a few seconds after each one and moves your hand to them "ass cheeks," She wiggles her butt a bit, stimulating you even more as said cheeks rub against your member "And nipples." She finishes guiding your fingers to rub her hardened nub.

"Any preferences?" You ask, bringing your right hand to her unattended breast.

"Good question, ten points to you, mister Potter." She says, back in her teacher role. "Of all my secondary zones my favorite is my nipples. I really like when they are played with. But they become very sensitive when I'm aroused so try not to be too rough, some girls like them pinched or pulled, like my sister for example, but for me is just painful."

"Got it. Like this?" You ask as you make circles with your palms pressing lightly on her nipples.

"Hmm, oh, yes!" She humms appreciatively. "But stop for a second or I won't be able to concentrate on telling you the last and more important part of tonight's lesson." She says stopping your hands with hers.

"The primary erogenous zones are those areas that are more commonly related to sexual stimulation and they consist of the genitalia, in my case my vagina, in yours your penis and testicles, then there is the anus and the perineum wich is the flesh that's between the two previously mentioned areas. These areas have some of the most tightly packed nerve-endings in the body, and they respond strongly to touch." She says bringing her left hand to her waiting pussy and spreads her outer labia as her right hand brings yours to a fleshy nub at the top of her slit. "Tonight we will ignore my anus and perineum and concentrate only on my genitalia. This is my clitoris and it is one of the most sensitive spots on my body. While most of the work in the female masturbation happens in or around the vagina it is also important to give the clitoris enough attention." She guides your hand further down until you reach a wet and slippery hole. "Unlike what some boys might think us girls do not pee from the vagina, there is another smaller hole just above it called the urethra; and when we get aroused or as they commonly call it 'wet' it's not that we pee ourselves. That is a natural lubricant that our vagina generates to help with the act of penetration." You groan, remembering a certain conversation with your dorm mates.

"You overheard Seamus back at the end of first year." You affirm more than ask.

"We overheard Seamus." She puts emphasis on the 'we' "A perfect had to come to our dorm to tell us to quiet down because we were laughing too hard. I think that was one of the few times that I bonded with the other girls. Even if it was over the stupidity of some boys."

"In my defense I'll say that I didn't correct him because he was so convinced that he discovered some kind of girls secret that I didn't want to crush his illusions. And I'm pretty sure that Dean knew that it was wrong too because he is also muggle raised so he must have had biology class at his previous school. Neville was too embarrassed to know what he was thinking and Ron fell for it hook line and sinker until the twins gave both of us 'The Talk' later that summer." You chuckle remembering the face of the redhead when he discovered that he was wrong.

"Okay, okay. Just making sure that you know that I didn't pee myself." She says laughing too.

"So, Professor Granger. Have we reached the practical part of this lesson?" You ask kissing the side of her neck and playing with her nipple.

"I guess we did, mister Potter. Show me what you learned" It seems like she has perfected the strict schoolteacher voice. "Just remember to be gentle. Okay, Harry?" She adds in a more vulnerable tone as she puts her hands on her knees to let you do whatever you want without interference.

"I will." You whisper as you continue to pay attention to her earlobe. You move the hand that was tending to her breast down to caress her stomach while your other hand works on her sex.

Your thumb rubs gently her clitoris in circles as you press the pad of your middle finger into her entrance. With a squelching sound your finger disappears into Hermione easily. She lets out a small gasp and her breathing becomes heavier. You marvel at the warm and snug feeling of the inside of Hermione's vagina. Your finger retreats almost completely before going in again. All this without stopping the other ministrations. All that multitasking training for quiddich sure comes in handy.

"You... you can put another finger in." She gasps after a while.

You do as she asks, squeezing your ring finger into her. Her gasps become small moans with the words 'Oh', 'yes' and 'Harry' mixed between them; those moans increase in volume as you return the attention of your left hand to her breasts. The walls of her vagina contracts around your fingers. Her juices running down from her pussy into the crevice between her buttocks coating your dick.

You suddenly remember that part of the reason why your last orgasm was so strong was the buildup and if you want to do the same for Hermione you should take your time making her cum.

You stop rubbing her clit and gingerly extract your fingers from her sex.

"Why... ah, ah. Why did you stop? I was almost there." She asks, panting.

"I got an idea." You say when she turns her head to look at you. She bits her lower lip a bit unsure. "You know I'd never do anything you don't want me to do and you just explained to me very clearly what you find acceptable and what you don't. And I really think this will make you feel as good as I felt earlier."

"Okay, Harry. I trust you."

You turn her sideways on your lap. You left arm supporting her back while you right hand goes back to caress from her pubic hair up to her belly button and back again. You also kiss your way from her neck down to her right nipple. You lick and suck on it for a bit before giving the same treatment to the other.

Hermione starts moaning again and again until, with a sudden cry she gives a shudder and goes limp in your arms.

You stop, confused. Did she just?

"Did you just made me cum from my breasts?" She asks incredulously.

"I guess so." You reply surprised. "How was it?"

"It was nice but..." She trails off, slumping against you. "It lacks something."

"Sorry." You say. Dammit the plan backfired.

"No, it's okay and anyway you are hard again." She says wiggling her butt. "Maybe, maybe it would be better if we take care of our problems at the same time." She looks at you with a hungry look in her eyes.

"You mean?" You ask as she rearranges herself to straddle your lap.

"intercourse," She says putting her hands on your shoulders "sex," She pushes you back to lie on the bed "fucking." She kneels on the bed still straddling you and grasps your cock aligning it with her soaking pussy.

As she is lowering into you the door opens suddenly startling you both. Hermione jumps back, falling from the bed and landing on her butt.

"Really, Herms. Do you know how lucky you are that mum and dad's room is downstairs?" You lift your head and see Julie strutting into the room this time just with the same top from before and a pair of rather skimpy panties. "Have you forgotten how loud you get when you cum?" She says bending down and flicking Hermione on the forehead. "I understand that you want to play with your boy toy. I really understand." She adds giving your stiff dick an appreciative look.

"He's not my boy toy." Hermione protests weakly.

"Okay, boyfriend then." Julie's smile widens at the lack of denial. "About time you admit it. Anyway couldn't you have waited until tomorrow when mum and dad will be gone all day and we'll have the house all to ourselves. You know that dad only agreed to let Harry stay because you gave him your word that it wouldn't happen what was about to happen, and if you two had kept going they would have heard the ruckus. They expect something like this from me not from you."

"I didn't..." Hermione trails off looking properly chastised.

"You owe me one, Hermione. You both do." Julie says embracing her sister, before getting up. "And next time use this." She says, turning to you, taking something out of her cleavage and tossing a pack of condoms into your lap "I'm too young to be an aunt." She says turning to the door showing that what she's wearing is a thong not panties. When she's at the door she turns around and asks "So does this mean that Harry here has accepted our family tradition?"

"Yes." Both you and Hermione answer at the same time.

"Great." She says taking off her very tight top freeing her generous tits. "Here." She tosses the top to Hermione.

"Wait a minute, isn't this one of my tops?" She says picking it up. "Julie! You ruined it with your... your udders." She puts it against her chest showing that it was stretched past its limits.

"You never wear it anyways. But here." Julie says slipping out of her thong and tossing it to Hermione making it land on her head. "Have my favorite thong as an apology. Good night both of you, have nice dreams... of me preferably." She says going down the hall to her room.

"That, that... arrgh" Hermione is still fuming as she throws Julie's thong to the floor.

You finally sit up on the bed as Hermione turns to you. "She's infuriating, but she has a point. If my parents had caught us it would have been a disaster. Maybe it's better if we go to bed. Each to our own bed I mean."

"You are right."
