After the first time having fun with custard Katy and Tim had added a new dimension to their relationship. There was so much more to try once they started looking into it some more. With Tims birthday coming up Katy started plotting a special treat for him. She had seen the look on his face as he had covered her in custard and it had been an incredibly fun and sexy experience that she really wanted to try again.

With time to plan katy started looking into something different to the custard they had already tried. What caught her eye as being really appropriate for the occasion was cake batter. She could easily buy some extra when she went to get the things for his actual birthday cake.

Last time they had both been completely naked this time she decided she was going to dress up a little. Not too much as she wanted to feel the cake batter on her skin. After going through her lingerie and pajamas she settled on a satin playsuit with a halter neck. The V went all the way down to her waist so plenty of skin on show. Tim had already told how great it looked wet when she had worn it in the shower a few months ago.

So on the day of tims birthday she let herself into his flat and prepared 3 lots of ready mix chocolate cake batter, one she dutifully put in the oven to bake the other 2 she hid on top of the bathroom cabinet after adding bit more water just to make sure they were runny enough.

when tim got home, katy was changed and waiting for him in just the playsuit.

"Treat now or after dinner?" She asked

TREAT NOW! Tim grinned pulling her close and kissing her as he ran his hands over her satin clad bum

Grinning katy took his hand and led him to the bedroom, once there she started to unbutton his shirt kissing his chest as she worked her way down. She kept undressing him until he was stood in just a pair of black trunk style boxers, with a very obvious bulge.

He groomed as she kissed the bulge before standing and walking through to the bathroom. After making Tim sit at the end of the bath and instructing him not to move. She carefully moved the 2 bowls of cake mix to where they were hidden behind the shower curtain within reach but hidden from tims view. Sheturned the shower on, checked the temperature was warm but not hot and hit play on her phone. As the music started she stepped into the bath and started to sway and move her body to the music. Keeping her eyes locked on Tim she moved slowly back under the spray feeling the material cling to her body and seeing tims eyes light up. Running her hands over her body feeling the satin across her nipples excited her more. She turned around under the spray letting Tim see the material clinging tight across her arse. As the song ended she turned the shower off and turned to face him. The spray from her dancing under the shower had soaked his boxers and she could see the water droplets on his skin.

The next song started to play and she reached behind the shower curtain and picked up the first bowl. Tims eyes widened as the bowl appeared and his breathing quickened as katy lifted the bowl up above her head.

She could see his reaction and shiver of excitement ran down her back as she tilted the bowl and began to pour.

Time seemed to slow as she waited with anticipation for the batter to land but when it did it flowed in a slow but steady wave over her hair and down her face. As it ran off her chin and onto her chest she pulled her tummy in and thrust her chest up to meet it. She felt it flow over her breasts and funnel down her cleavage over her bare stomach, it started to pool in the folds of the material around her waist. Some over flowed and ran over the outside of the playsuit over her crotch with the material clinging tightly to her.

WOW!! was all that Tim could say, she grinned and gyrating to the music she ran her hands up through her chocolate covered hair slicking it back as the batter ran down her bare back some finding it's way down between the cheeks of her bum. Her hands then spread the batter over her chest before she reached behind her neck to undo the halter allowing it drop. Her hands ran over her breasts feeling the batter against her sensitive skin.

She pulled open the waistband allowing the batter to run down and over her crotch adding a whole new sensation.

Tim had released his hard cock and was gently stroking it as he watched his girlfriend caress her chocolate covered body.

Seeing this katy, reached for the other bowl of cake mix. Kneeling infront of him she began to pour the chocolate over his chest and down over his boxers his hand sliding the mix up and down ad he continued to stroke himself.

Let me help with that katy whispered hoarsely putting the half empty bowl down on the side.

Moving herself between his legs she moved so that his hard cock was sitting snuggly in her chocolate cleavage. He groaned as she pushed her breasts gently together feeling him slide between them.
She was as lost in the moment as Tim was until she realised he had noticed the left over cake mix. She grinned as he picked it up and began to pour it over her breasts and up over her hair . Dropping the now empty bowl he began massaging the mix into her hair. She could feel him tensing and suddenly with a cry, Tim released and she felt his warmth land first on her chin and then her breasts. She didn't stop until she was sure he was empty before pulling him down into the bath with her and kissing him as she pulled his body against hers.

Happy birthday! she whispered.
