You invited your colleague to your wife's birthday party, as she's a mutual friend, with the understanding that they don't really get on... but she flirts with you a lot and she's a hot readhead. She turns up early and starts on the beverages, you find her in the living room alone messing with the cake and tell her off but she mocks you. She ends up pouring her glass all over it... Now what? Your reaction makes her even more insolent... she starts licking the icing off the top and tells you she's going to really ruin your wife's birthday. Next thing you know, she's on the table with her dress pulled up showing off her magnificent arse in her little thong. Before you can stop her, she plants her arse down on top of the cake. It's flattened - but that's not enough for her, she bounces on it many times, squashing it down into the tablecloth before spinning around and pulling out her pussy - she grabs handfuls of the crushed cake and rubs it into her bare folds. She tells you your wife is old, fat and not good enough for an alpha man like you... Your cock is solid by this point and she notices. She wants you to fuck her on top of your wife's cake... You plunged into her wet, cream and cake covered cunt - stuffing some of the mixture inside her with your cock. She's so wet and feels amazing around you. She insults your wife while you fuck her and moans how good you feel. She pushes you on your back and rides you, squashing the cake even more beneath both of your bodies until she cums hard around your cock and begs for you to fill her up. You oblige and spill a gigantic load in her pussy - she's right, it has been a long time since your wife has fucked you - and she pushes your creampie out all over your wife's ruined cake. Happy fucking birthday to your cunt wife.
