The kissing is great as far as it goes. Ron has an armful of Hermione's back and handfuls keeping him interested in her chest. She leans into him and wraps her free arm around his shoulder. Her other arm is against Ron. She keeps it straight down at her side - all the way down into his lap. She turns her wrist to cup his testicles and stroke that penis that fascinates her so much. Its combination of soft and hard leaves her wondering how it stood up to her grinding action.
He wonders what she's ready for next. He's afraid he'll get it wrong or go to fast for her. He really doesn't want to scare her or drive her away. He tries to think what was next with Lav-Lav. Hermione is thinking of Lavender as well. She knows she has the smaller breasts and she can see how much breasts interest Ron. Did he have this much privilege with Lavender's body? Does he like her breasts? Her responses? Her passion?
Her passion surprised even Hermione. That grinding wasn't conscious. It's what her hips wanted to do all on their own. It was natural, sexy and oh so enjoyable. What she's afraid of is how all that compares with Ron's experience. Does he like Hermione's response?
Ron hasn't had his hands on Lavender's chest at all or seen anything that was under her clothes. Hermione is doing things that are all new to him and he never expected her to do. He takes a little courage and tries even more. He slides his hand down her chest and over her stomach. He feels rippling muscles under her soft skin. That thrills him as much as the feel of her hand on his penis. The combination makes it twitch and leak another drop. Hermione presses toward him and pulls his head to keep their kiss going.
Ron slides his hand farther down. This is getting close to something he thought Hermione would never let him do. He gets more worried he won't do it right. She knows exactly where his hand is going. Her hand was there just a few days ago. She knows how she'll react, but will that be good enough? How much has Ron-Ron done that before? How did Lav-Lav react? Ron's fears stop him. He takes his hand away from her. He forgets for the moment who had the idea for this whole adventure.
They've been going well and are fully excited by the prospects. They're not alone, though. Oh, nobody is with them physically, but they've both been thinking of Lavender. They both feel awkward and nervous. They break the kiss and back off. They're both breathing hard from their passionate reactions and stammering because they're nervous. They don't actually say words to each other, but they both stop playing with each other's body.
Hermione rolls off his lap into the bath. The warm water with those thick scented bubbles feels so luxurious. She floats on her back and kicks away from the edge. She cuts through the bubbles and Ron can see all of her when he looks down through the clear water.
He slides off the deck, ducks under the water. He tries to open his eyes and take in the sight of the parts of Hermione that are under there. The soapy water burns his eyes so he closes them quickly. He comes up smiling anyway. He's anticipating the sight of Hermione swimming around, but he can't see her. She pushed up such a pile of bubbles that she's hidden. Some of the bubbles tickle Hermione and she giggles. Ron pushes off from the side of the bath and glides through the water in the direction of her laughter. Another laugh comes from a little farther away, so he gives a few powerful swimming strokes in that direction.
He finally bursts through the wall of bubbles, discovers Hermione floating along and seizes her. He lifts her up to his mouth and starts another deep kiss. Her feet are off the floor. She's dangling down Ron's front and feeling everything he has there. She's pressing against his strong chest, stomach and legs. His hard penis is trapped between them again and exciting them both. Just because it makes her feel like it, she starts to wrap her legs around him.
Ron breaks the kiss and drops her saying, "You're it."
"Eep!" Hermione protests as she falls.
Not only does she miss the tight hug and his tongue in her mouth, but he dropped her into the water before she could put her feet under herself. She falls into the water and winds up sitting on the bottom of the bath. She finds out that soapy water burns her eyes, too. By the time she springs to the surface, Ron is nowhere to be seen.
As it was with him, Hermione's only clue to where Ron went is in the sounds. She hears the splashing of his swimming. She glides through the water with a breast stroke. She thinks it's ironic that she'd use that stroke to get her breasts back into his hands. She figures out which way he's going and cuts across the corner. She intercepts his path and waits. When the gap in the bubbles arrives, she pounces. She jumps on his back with a wicked squeal as he's swimming by. He looks up just in time to see her grin and a lot of her naked body before he's driven under the water. Both of them wind up at the bottom of the bath. They struggle and wrestle with each other, but only briefly. They are under water, after all. They don't think of a bubblehead charm or gilly weed until much later.
Ron holds Hermione tight against himself as he stands. She'll go along with that, for now at least. She's getting another deep kiss, passionate sparks from his tongue and tingles everywhere her body is against him. The idea of that hard penis has the tingling spreading to parts between her legs that aren't touching him.
She soon thinks of revenge, though. This kiss has gone a little longer than the last one when she breaks it. She gently strokes Ron's cheek and ear with one hand while she snuggles her face to the other side of his.
"Now you're it," she whispers in his ear.
She arches her back, pulls her legs away from him, tucks up and plants her feet against his thighs. She gives a powerful push with her legs and breaks away. Her thrust pushes her through the water on her back again. It also knocks Ron's legs out from under him. He's dunked again. He's also out to find Hermione. He thinks tickling her naked body would make a good revenge.
He tries listening, but Hermione is being very quiet. He swims and searches and eventually catches her. Hermione anticipates more hide and seek, so she only gives him a quick kiss. Her hands do more. One arm around his shoulder holds her up. The other gropes and strokes his penis. He has an armful of his girlfriend, she has a handful of his penis and he gets a much better idea than tickling. The idea of tickling goes to second place when he sees where they are. Dispensers for scented lotion soap are right there.
Just as she starts to break away for more hide and seek, he says, "Wait, Hermione. Lets wash."
Ron has taken courage from Hermione playing the game with him, naked as they are. She is more confident that this is something he hasn't done with anyone else. Thoughts of an old girlfriend are gone.
Hermione hangs on Ron while he draws out some of the soap. She snuggles her body against him while he rubs the soap in her wet hair, over her ears, neck and shoulders. She hopes some tingly parts of her chest are next for him. She stands away a little to give him room, but he actually washes her back first. He gets to his favorite parts of her chest right after. He spends some time on those, but not too much.
He stands at her side. She turns her head and looks up at him with a sly expectant smile as only Hermione can. One hand reaches down her back. The other reaches down over her stomach. Those reaches are all under water, so he doesn't bother with soap. That's still the excuse, though. Hermione got a lot of tingling from his attention to her breasts. She's anticipating more and more what will happen in a few seconds. His hands get to her butt and her mound.
"OH!" Hermione gasps and her legs give out.
She drops straight down into the water. Playing in the bubbles is over and they both know it. Ron lifts her onto the deck. She lies back with the sort of warm smile that's sure to invite him to carry on.
