Libby was 5' 8" tall, with long blonde hair, pale blue eyes, and a 34D 24 34 figure. Mark thought he'd won the jackpot when he met her four months ago, getting to fuck her on the first night, but now he was seeing the downside. Because of her looks, Libby got a lot of male, and female, attention, especially from Mark's friends. She laughed it off, asking Mark if people should think she was unattractive and slag him off for having an ugly girlfriend.
Every Saturday night they'd go out and the night would usually end with Mark arguing with someone about the way he'd supposedly looked at Libby. At first, she found it amusing, him defending her honour, fighting her corner, but now it was getting tiresome that they couldn't just enjoy an evening out together.
The Saturday thing was to get them away from the house for the night. Mark's parents had divorced and his mum had moved away, and he had stayed with his dad Ian. Every Saturday Ian had friends around for drinks and they watched movies and played cards, usually poker. This Saturday Libby hoped things would be different as it was her 20th birthday. The one thing that would be better was that they were going out to a house party, a lot of Mark's old school friends were having a reunion.
Libby liked Ian. He was pretty sensitive, she'd already found he'd listen if she wanted to vent, usually about Mark, and then Ian would find a way to try to softly speak to him about it. He had a similar sense of humour to Libby and was very fond of giving her hugs when greeting her. Mark had moaned one night it was an excuse to squeeze her close and feel her tits pressed against him, Libby telling Mark he was so very wrong, at forty-five years old Ian was far too old for her even if he wasn't Mark's dad.
With Saturday approaching, although it was her birthday she had a treat lined up for Mark too, but he'd have to find out what it was for himself. She'd been lingerie shopping and had treated herself to a black corset with a zip front, with push-up cups that would enhance her already large tits. To finish off the outfit she'd bought some black stockings and a black see-through thong. The corset had no shoulder straps so wouldn't be able to be seen under her loose-fitting floral dress.
Mark didn't bat an eyelid when she turned up at his house ready to leave. Ian told her she looked gorgeous, complimenting her on the dress and how she'd styled her hair. he asked if the present he'd bought her had been enough, she told it was very thoughtful, and better than the money that Mark had given her in her card.
The party itself was quite enjoyable. Although she didn't know many people apart from the ones she'd met previously with Mark, there were constantly people making sure everyone had a drink, taking empty glasses from her and handing her another. The mixture of drinks loosened her inhibitions and she danced and sang loudly when a song played that she liked. She looked towards Mark who was frowning, not enjoying the male attention she was getting. She mouthed to him she was just enjoying herself, and he scowled and walked away. Twenty minutes later she went looking for him, asking people if they'd seen him.
"Oh yeah, he went upstairs with Mandy," one boy laughed.
"Who's Mandy?" Libby asked.
"Oh, she was the fittest girl at school and Mark had a major crush on her. You'll have to find someone else to chat up," he laughed in response.
"She's his girlfriend you dick," the girl with him said, punching him on the arm as she did so.
Libby went upstairs, where could Mark be and what is he doing Libby thought to herself. She saw him at the end of a corridor by the bathroom, with a brunette, both had their backs to Libby.
"Oh, there you are," she called out.
The two of them jumped and she saw the brunette's hands move from in front of Mark.
"What's going on?" Libby demanded.
"Nothing babe, chill out," Mark said.
"Nothing is happening, we were just talking, reminiscing about at school," the brunette said.
"Then why is your zip undone?" Libby asked.
"Oh, I hadn't noticed, I'd just been on the toilet," Mark said.
The brunette wandered off quickly leaving them arguing. Mark made things worse by telling her she was doing exactly what she moaned about him doing, arguing with people while they were out.
"I want to go home," Libby said.
"But it's only 10 pm," Mark answered.
"I don't care, I want to go," Libby told him.
Mark phoned a taxi and then went around telling his friends they were leaving, saying Libby had mixed her drinks and was unwell. He quickly drank five more shots before the taxi arrived. Getting in the back, he kept telling Libby he was sorry, pulling silly faces at her, leaning over and trying to kiss her. Libby had calmed down by now but kept up the pretence by pushing him gently away. She stopped moving him when he slid a hand up between her legs, expertly moving her thong to one side and sliding a finger along her dampening pussy.
Libby groaned and opened her eyes to see the taxi driver looking, adjusting the rearview mirror to get a better angle. He saw Libby watching and waited for the backlash. With Mark busy kissing the side of her face and his fingers rubbing along her pussy, she opened her legs a little more and smiled at the driver. All too soon for all of them, they made it back to Mark's house. Mark handed him some money and told him to keep the change, and the driver handed Libby a business card and asked her to call him if she needed a cab anywhere, winking as he did so.
They stumbled into the house, Libby having to hold Mark steady as the drinks were kicking in. Going inside, they saw Ian sitting with John and James. They were here every week, others visited as well some weeks but not tonight.
"Hi, we didn't expect you back so soon," Ian said.
Mark grabbed a bottle and took a large swig from it, burping loudly as he did so. Ian walked over to Libby and hugged her, and Mark grabbed her hand and pulled her away.
"I know what you're doing, we're going upstairs," he said, pulling Libby with him, "we're going to celebrate your birthday properly," he said, playfully slapping her arse.
Libby smiled at Ian and then got whisked through the door. Mark pulled her upstairs to his bedroom and then started getting undressed. He half undid the buttons on his shirt and pulled it over his head, then unbuckled his jeans.
"Come on babe, don't you want to fuck?" he asked her.
"Of course I do, but you need to undo my dress zip first," Libby instructed him, turning her back.
There was a delay as she heard him pulling his jeans off, and then she felt the zip being pulled down. Keeping her back to him she swayed her hips and took the dress off slowly, letting it fall to the floor. Turning and smiling at him, he was lying back on the bed, not looking at her, stroking his erection. As much as he could be an insensitive prick at times, he did have a very nice cock although it wasn't the longest he stayed hard for hours, and after being fingered in the taxi Libby needed her pussy filling.
She slid off her thong and crawled over him, straddling him and lowering herself down, taking his seven inches with relative ease. She rode him how they both liked it, her feet planted as she raised and lowered her hips, pushing down onto him as hard and fast as she could. His grunts got softer and softer, and Libby sensed something was wrong, his cock didn't feel right. She pushed his chest, and he groaned at her to leave him. She raised herself and his now limp cock flopped out of her, she pushed him again and he turned onto his side and told her to let him sleep.
Libby sat on the bed for ten minutes, pushing him and stroking his cock hoping for his erection to come back, but by now Mark was snoring. Libby decided to go downstairs and get a glass of water. She slid the thong back on and went to put on her dress, wishing she'd bought a change of clothes with her. She knew the dress would look weird, the zip at the back opened right down to the small of her back and she wouldn't be able to fasten it up much by herself. Looking down, she picked up Mark's shirt and pulled it over her head. With Mark being taller than her it reached almost to her knees and was also quite loose on her. Now Ian and his friends wouldn't be able to see what she had on underneath, although she couldn't hide her nylon-clad legs.
Walking down the stairs she could hear them all chatting away, as she walked into the room they all turned and stared at her.
"That was quick, you've only been fifteen minutes at most, we didn't expect to see you again tonight," James laughed.
