After a lot of trial and error on what he allowed me to write, I manged to get a descent story. I will let you judge.

It was a warm summer evening, and Sarah had just turned 18. Her boyfriend, Jake, had planned a special surprise for her birthday. As Sarah walked into the kitchen, she saw a beautiful four-layer chocolate sheet cake, with chocolate frosting on top, and drizzles of Nutella on it. She was delighted and moved towards the cake, but as she stepped on a wet spot, she slipped and fell face-first into the cake, covering herself from head to toe.

At first, Sarah was mortified, but Jake quickly reassured her that it was okay and that it was all part of the fun. He grabbed her by the hand and led her to the bedroom. As they entered the room, Jake pulled Sarah close to him and started kissing her neck. She could feel the warmth of his body against hers, and the sticky sensation of the chocolate all over her skin.

Jake started to smear the cake all over her body, and Sarah moaned with pleasure as he licked and sucked the chocolate off her skin. She ran her hands through his hair as he moved lower, kissing and licking his way down to her breasts. He took one of her nipples into his mouth and sucked on it, sending a jolt of pleasure through her body.

As Jake continued to explore her body with his mouth, Sarah grew more and more aroused. She couldn't resist the urge to reach down and stroke his hardening shaft through his pants. Jake let out a deep moan as she rubbed him, and he quickly removed his pants to reveal his throbbing member.

Sarah wrapped her lips around him and started to thrust her mouth back and forth, licking and sucking on him as he grew harder and harder. Jake groaned with pleasure as he grabbed her hair, urging her to take him deeper.

As he thrust into her mouth, Sarah rubbed and licked his shaft with her tongue, taking him in as deeply as she could. She could feel him getting closer to climax, and she increased her pace, bobbing her head up and down faster and faster.

Finally, with a loud moan, Jake exploded in her mouth, covering her face and breasts with his warm release. Sarah licked her lips, savoring the taste of him as they both collapsed onto the bed, completely spent.

As they lay there, covered in cake and each other, Sarah couldn't help but feel grateful for her amazing boyfriend and the incredible birthday surprise he had given her.
