Mel was pushing against Ben’s chest, trying to sit up to stop Jason’s cock totally fucking her ass but Ben pulled her forward. ‘She’s a wriggly little cunt aint she’ said Ben. ‘Tie her arms’ demanded Jason. Martin grabbed the rope, pulled my gf’s arms behind her back and tied them together at the wrists. She slumped onto to Ben’s chest and was now completely defenceless which allowed Jason full reign on her bum. He started to pick up speed, really thrusting into her asshole whilst Ben fucked her pussy. Martin grabbed her head and slid his dick into Melanie’s gob. She now had all her holes filled and my cock was close to exploding as I watched on my computer. As Martin fucked my girls face, he picked up a pen and I could see him writing something on her face. I couldn’t see what he was writing though as she was facing away from the camera. Ben and Jason continued ploughing Mel with her moaning on every thrust. ‘Shit I’m gonna cum’ shouted Ben. ‘Fill her up then man’ replied Martin. Ben let out a huge moan as he emptied his seed into my gf, her second cum load of the evening. After Ben had cum, Jason pulled out of her ass to allow Ben to slide of the bed. Mel, still with her hands tied behind her back, crashed face first onto the bed like she was just some sort of sex doll. They left her in that position whilst they started fiddling with the rope device connected to the ceiling. They attached a dog collar to the rope that hung down onto the bed. Martin then undid her hands, picked her up and turned her round so she was facing the camera on all fours and placed the collar round her neck. Jason pulled on the device which pulled the rope lifting Mel’s head slightly. As he head raised I got to see what Martin had written on her. On her forehead he wrote ‘Cum Slut’, on her left cheek he had written ‘Cunt’ and on her right cheek he had written ‘Martin’s Property’. It looked like he had written it in black permanent marker. The bastard, that may not come off for days! Once Mel was in position, Martin moved behind her and slipped his cock into her butt. He grabbed her hips and started to pound her. Jason moved to her face and offered her his dick which was fresh from her own asshole. She had no choice really as she couldn’t move away due to the dog collar restraint. He began stuffing his big dick into her mouth, making her gag again. Martin began building up speed, slapping her ass harder and harder. I looked at my gf’s face, her eyes had glazed over and she seemed trance like. Martin then unloaded into her butt, squeezing her cheeks as he shuddered. Within in seconds Jason whipped his cock from my girl’s lips and shot his creamy load into her mouth. He wanked his cock, ensuring she got every last drop. ‘Swallow it whore’ he shouted to which my girl obeyed. Martin removed himself from her ass and undid the rope but left the collar on her. He flipped her over so she was on her back, head slightly of the end of the bend facing the camera. ‘Congratulations, you got an A ’ he said. ‘After doing so well on your exam, I think you deserve a little treat’. With that, John and Ben both returned to shot. They bent over my girl’s face wanking their cocks furiously. My gf just lied there smiling. John was first to cum as he shot 4 big dollops of spunk covering her face. Then Ben unloaded. His cum hitting her between the eyes and shooting off on to her forehead. He squeezed his cock one more time and then knelt down and gave her a big kiss on her lips. Martin helped a cum covered Mel up and sat on the end of the bed with her on his knee. ‘I hope you enjoyed the show mate’ he said. ‘We’ll drop her back into town tomorrow at some point and she can give you a ring to come pick her up’. Shit I thought, drop her into town? Everyone will see what she is and know what she has done. Martin turned my girl and whispered ‘Say goodnight to Jamie’. ‘Goodnight babe, I hope I did everything you wanted’ Mel said. Martin then turned Melanie’s head towards his and started to passionately kiss her. Then the cam was turned off and my screen went black. # I hope you all enjoyed reading my experience. It was so horny remembering the details and writing it for you all to read. I have loved all the comments, especially the detailed ones. I will re post the whole story as one story so those who missed the first 3 parts can read the whole thing.
