Mark, her brother, storms in ()

The bathroom door swings open. "Jess are you alright?" He screams. Jessica freezes, Her hand still buried deep inside her pussy and the other still firmly gripping her tit.
Mark also freezes and stands in the door opening. they stand there looking at each other. Shocked at first... but this stare lasted longer... it continued what seemed to be forever. She saw how he looked at her.
Then: a sparkle in her eyes. Defiantly her hand started rubbing her pussy again. slowly at first but soon she was rubbing as fast as she could. She watched how Mark was watching her. How he was slowly rubbing his pants. She arched her back as she was about to cum. Tensing all of her muscles as her pussy screamed in pleasure.
"The water is lovely" she said invitingly once she came to her senses. She watched how Mark removed his clothes without ever taking his eyes off of her. When he removed his boxer his dick sprang out. Jessica opened her legs a little as if she was inviting it in.
Marks walks into the shower and puts his hands around her. She meanwhile moved her head forward towards his. An ever smaller growing stream of water separated their lips. She kissed him, he kissed back. Their lips parted, tongues entangled they embraced each other while the water splashed down on them.
She felt his stiff dick press against her wet throbbing pussy, which was still coming round from its orgasm.
She Slowly went down onto her knees until she was eye to eye with marks dick. She licked her lips before she started flicking her tongue at the head of his dick. she moved her tongue all along the shaft and back up again.
With one hand she fondled his balls while her other rubbed his inner thighs. Mark reached down and lay his hands on her head. "You are the best, sis." he said. She smiled. She opened her mouth and took her brothers dick in. "hmm" he moans approvingly.
While his dick is in her mouth she flicks her tongue along the head. the hand on his thigh moves up again towards his shaft. Jessica notices how Mark looks down on her so she steps up a notch to please him.
After a while Mark helps Jessica up again. "I don't want to blow my load just yet..." he says. with his hand he rubs her clit a few times before he takes his dick into his hand and moves it towards Jessica's pussy. she arches her back a bit pushing her pussy forward so that her brother can enter her more easily. her enters her and starts thrusting. after a while Jessica turns around and braces herself at the walls of the shower. Mark lines up behind his sister and pushes his dick into her pussy. He smacks her ass as he trusts his dick inside of her. He increases speed as he is coming close to cumming. He moans as he shoots his load into his sisters pussy.
Jessica turns around and kisses her brother again. "That was great she said."
She said.
Mark turned off the shower and they dry each other off. Jessica gets dressed and ready for school quickly, she's already late as it is.
