I plan on using a small, thick, cylinder cake rather than one of those large sheet cakes. More cushion for the pushin. I don't plan on climaxing, personally, because I will serve it to my friends after (after they witnessed me fucking the cake, I mean, I think it'd be fucked up for them not to know I fucked the cake). You can use a condom if you want to, so you dont get cake on your dick. I'm pretty sure it'd wash off easily, though.
Wouldn't you rather have your boyfriend fuck a custard roll? Then it would be tastier to lick him clean. I say this because my favorite dessert is vagina topped with whip cream.
At first i thought this was sick and you need help mate but now...u still need help but i'd eat cake i've seen a friend fucking.Just cause its so insane it will definately be a memory worth having.
