Regretting Cake

So my friend said his sister was saying her vows In a low key church ceremony three weeks from now No parties, no showers, no flowers, no muss But I thought to myself she deserved a small fuss! So I planned a surprise that would redden her face A Bachelorette Party so hot and debase She would never forget for the rest of her days That wee bit of naughty before strict married ways. I invited her over to casually dine And not knowing her friends, I invited all mine. I decorated the place with men's private parts And hired a stripper from "Bachelor of Darts." She arrived right on time, a quarter past seven And I found my friend's sis was a slice out of heaven And that description is not the slightest bit shabby As his "sister" was a nun from the neighborhood abbey! I welcomed her whilst I was gesturing frantically For my friends to hide all that would shame me gigantically And to their credit they did, even cancelled the stripper And we dined and chatted til I was feeling quite chipper We finished the meal, and I went to the loo When suddenly a scream went up from my crew I ran to see sister slumped, white as a ghost And a room full of people hysterical almost There in front of the nun sat the special dessert I had ordered before meeting the sweet Sister Gert It was fully erect, took a long time to make And for the first time I found myself regretting cake!!! 8/7/2016 For contest "Regretting Cake" Finalized 8/14/2016 Now for "Take the Dagger from my heart, Please"
