Showering together.

Both now in the bathroom that was adjacent to Cindy's bedroom, Callum turned on the shower and Cindy grabbed 3 towels.

Cindy was given a wonderful sight, as she watched her brother pull his boxers down and expose his semi-erect cock. She couldn't help leering at it.

"Waters fine now." She announced, as she stuck her hand under the shower head and felt the water.

"Great." Callum replied, as they both stepped in.

They both had a quick rinse under the water, to get their bodies nice and wet. Once they were both slippery, Cindy squirted some body lotion into her hands and began lathering up Callum's body. She couldn't help biting her lip, as her hands glided over Callum's toned body and spent an exceptionally long time caressing his butt.

Cindy's eyes had a slight twinkle, went she saw Callum's cock twitch as she soaped his crack, making the mind wonder and thinking that her brother might like anal. Finally, Cindy began lathering up the cock and began gliding, up and down with one hand and massaging the balls in the other.

"W-what are you doing?" He stammered.

"You need to clean this area too, you know?" She replied, in a really patronising tone.

Feeling the hard and warm member, twitch in her hands, made Cindy feel a little spark inside.

"Alright!" Cindy suddenly burst out. "Put this on me." She instructed, passing her body lotion to Callum, faced away from him and prepared for magic.

It took everything to stop herself from fapping her brains out, as Callum began massaging the lotion into Cindy's shoulders and as his rock hard member was pressed against her butt crack. Once her shoulders were lubricated, Callum began lathering the lotion into Cindy's magnificent breasts. She couldn't restrain herself, Cindy began to moan softly, her eyes jammed shut.

Cindy's top half now soapy, Callum knelt down to continue the lower half. But when Cindy felt his breath on her butt, she couldn't help herself. Instantly spinning around, she shoved her crotch right in his face and began thrusting wildly.

The pleasure had completely taken over her body and brain, she didn't care if she did trick Callum yet, all Cindy wanted was to cum.

Rough, would have been the understatement of the century. Cindy was thrusting with everything she had. Juices flooded Callum's face, who was in total shock, unable to understand how he got into the scenario. His older sister, grinding on his face like no tomorrow.

As Cindy was reaching the tipping point, Callum foolishly opened his mouth to breath, so Cindy took her chance and shoved her pussy into the openning and screamed to kingdom come.
