The bath was nice and hot, and Sebastian threw his head back, over the edge of the tub. His lip curled with satisfaction, always enjoying the nice warmth of a filled bathtub.
But it was the sound of a pair of feet padding towards him that made him smile even wider. He bared his teeth, smiling up at the ceiling, eyes still closed as he heard the sound of her bathrobe drop on the floor. He lazily opened his eyes and rolled his head back, catching sight of her in her naked form. He offers her his hand, which she takes and she steps into the tub, first trying her toes first to see the warmth before dipping her leg in entirely, her second following, sinking through her knees and down into the water.

She let out a sigh of pleasure, taken by that feeling you always get when stepping into a bath that's just perfect. Sebastian knows that feeling too well. He happens to love taking baths, and what better way to enjoy it with a pretty girl sitting between his bend knees.

The tub is small, he agrees, but he props one leg up to the side of the tub to give her more space. He has already done the noble deed to sit on the plug, which is never a nice thing and when he shifts his leg he accidentally touches the metal pipe of the hot water tap, yelping with pain and jolting up, pulling his leg away from the hot source. Water splashes over the side and he swears unnecessarily loud, rubbing his leg and quickly dipping it in the (somewhat) cooler water. She laughs.

'I was going to say: "this is nice",' she chuckles as she rubs Sebastian's leg as well.

'Usually is,' Sebastian agrees, the corner of his lip curling. 'You know what's even nicer?'

'What?' She asks with that wide smile of hers; that smile that's actually a bit too wide, but it's what makes her so adorable.

'Ever had sex in the bath, Hooper?'

The smile is wiped off her face as she stares at him, her cheeks flushing even redder than they already were, caused by the heath of the bath.

'I— well, no. But—

'Wanna give it a try?'

'Er— sure but, is that— possible?'

'Sure it is,' he says and extends his hand towards her. 'Come on.'

She takes his hand and indicates her to stand up. He shifts forwards to the middle of the bath and indicates her to sit on his lap and wrap her legs around his waist.
As soon as she sat down on his lap he grew hard; of course that was bound to happen, but hell, it was necessary anyway. She blushed against as she felt his hardened manhood push up against her and he smirked. Nothing he could help.

He leaned forwards, kissing her slowly and wrapping his arms around her waist. He caresses her back, smooth and warm from the water they were bathing in. They had the advantage of the water so that she didn't have to be ready for him, so he pulled her closer, took a hold of his cock and gently guided it into her, pressing her closer to prevent from slipping out of her.

'Easy as that,' he muttered against her lips, wrapping his arms tightly around her tiny body, craning his head back a bit as her face was now higher than his. She buried her hands in his hair, softly kissed him, her lips stiff from smiling awkward at him.

He rocked her forwards, his hands on her hips and pulling her towards him, letting her know what motion she had to make to create the friction. She soon picked up the motion.
It was warm. It was soft. It was wonderful. She gently rocked her hips, their lips only parting to kiss. The friction is minimum, but it is enough for he can feel her contract around him a few times as she comes. And after half an hour of kissing, caressing, touching and nipping, he breaks off the kiss, letting out a shaky sigh as he reaches his own climax, closing his eyes with delight, opening them again and smiling up at her red, flushed and sweaty face.

She wraps her arms around his neck and rests the side of her head against his.

'That's certainly nice,' she agrees and he chuckles fondly at little Molly Hooper.
