You offered to be Wendy's birthday cake and your oldest sisters helped prepare you, by putting frosting on your naked body. Before you know it, you are presented on a plate in front of your favorite sister.
"So you're my cake today, huh?" she said.
"Yep!" you said, "Eat up!"
"Guess I can't talk you out of this." she laughed.
Your sister grabs your body, swallowing it up. She's enjoying the sweet flavor she's getting from your body and keeps going and going. It doesn't take long for your shoulders and bare chest to squeeze into her mouth and head down her throat. You then feel her tongue on her stomach and then you feel your now hard cock enter her mouth. She gulps down even harder getting to your legs and approaches your knees. As soon as your naked body is completely in her belly, she lets out a loud belch.
"Thanks for the cake, little brother." she said, hugging her belly.
