spunk on a cake

It was Sarah's Birthday and after spending the day with family she was looking forward to going out at night, with here best friend Thelma. She got changed and and came down stairs with a short dress on and high heels, black stockings etc, my cock was rock hard and she sat down on my knee and opened her legs and my hands were on her pussy rubbing the black satin panties she had on, I nearly shot my load but I managed to hold back.
She got up and adjusted her panties and dress, finished her make up and asked if I would take her to Thelma's house, I pulled up outside their house and dropped her off, I watched her walk up the drive and saw the door open it was Thelma's partner Robert, he shouted to me that Thelma had to nip around to her mothers and that she would join them later, so I drove away, after about 10 minutes or more, I couldn't stop thinking about Sarah being alone in the house with Robert and his mates as they were planning a lads night out, and I couldn't go because of work the next day, so I turned the car around and drove back, I pulled up outside the house and walked up to the door and knocked and walked in, I went into the living room and no one was there but I could here geering and laughing coming from the integral garage, so I went to the door and saw Robert and seven of his mates all wanking over Sarah who by now was bent over a sofa chair with her legs apart and her dress up around her waist and three of the guys rubbing their cocks on Sarah's tight black panties that had by now gone into the crack of her arse, Robert was the first one I saw slide his cock between her crack, she had now put a cock in each hand and was sucking on one, within 10 minutes she was being fucked all over the place and Robert had brought in a sponge cake which he had placed on a table, Sarah wanted a layer of spunk on top of the cake, of which a few of the guys duly did, she then asked Robert to sit in the chair and she bent over sucking his cock good and hard, while being fucked relentlessly from behind, after all the guys had shot their load, she pick the cake up and shoved his nose and tongue into the sponge before standing up and shovong some of it into her mouth, I knew then that this had been planned but I knew Sarah would be enjoying thi special birthday shagfest, I made my quick exit and drove home, all the way with an hard on.
