As she undressed and got into the shower Natalie once again felt the mixed emotions of excitement and worry. For a short while the excitement took over while her hands, lubricated by the shower gel, wandered over her body. She knew that her tits and pussy were no dirtier than the rest of her, but she gave them extra attention anyhow, enjoying the sensations as the stroked and teased herself. She was rudely interrupted by her husband banging on the bathroom door demanding to know when he could have the shower. Reluctantly she got out and opened the door to let him in. He was already naked and as he entered the bathroom she reached out to cup his balls, then gently scrape her fingernail up the bottom of his rapidly hardening cock. With a wicked grin she kissed him and went through to the bedroom just as his erection reached its peak. Normally she loved a good fancy dress party, but this one was advertised as having an adult theme, with guests expected to dress as sexily as possible. What if her outfit was too revealing compared with everyone else? What if she looked overdressed next to all of the others? What if the adult them carried over into behaviour and not just dress? Natalie sort of convinced herself that there was no point in worrying about these things and she may as well get dressed, go down to the party, and enjoy herself. With a mental shrug she pulled on her red stockings, and small red lacy thong. The rest of her Little Red Riding Hood outfit comprised a very short dress that just revealed the lower curve of her buttocks when she was standing upright. The dress did of course have a hood, but there was very little else to it, especially at the front where it was open right down to her navel. Her breasts were only small but she was very well aware that they were not well covered up and the chances of her inadvertently flashing during the evening were very high. Just as she finished dressing Pete came out of the shower and gave an admiring whistle, telling her how sexy she looked. As he tried to slip his hand inside the front of her dress she smacked his wrist and told him they didn’t have time. They both laughed and he quickly got dressed. His Sixties flower power outfit was much less revealing than hers, although she couldn’t help but notice that the tight trousers showed off the bulge of his cock as it pressed against his leg, making it obvious that he was not wearing underwear. They shared the lift down with a couple in togas, which both revealed large amounts of bare flesh, and Natalie started to feel a twinge of excitement at the prospect of the evening ahead. When they got into the main room, there were already a large number of couples there, and she was delighted to see that her outfit appeared to have struck exactly the right balance. As she looked around the room, Natalie was more than a little surprised to find that her gaze was getting drawn more to the women than the men. What’s more she was starting to feel a little turned on by some of the revealing outfits and the fit bodies that were being displayed. She could tell by the growing bulge in Pete’s trousers that he was enjoying what he saw as well. After getting drinks and wandering the room, they bumped into the couple from the lift again. This time they all felt a bit more relaxed, so actually spoke to each other. The couple introduced themselves as Bob and Sue. They enjoyed the usual small talk about where they were from, what they did for a living and the like. They also had a few more drinks, and Natalie was starting to feel much more uninhibited. Without any warning, she blurted out “Are you two wearing anything underneath those togas?” Pete looked stunned but Bob and Sue just laughed. “Check for yourself” said Bob, taking Natalie’s hand and guiding it up underneath the bottom of his short toga. She gasped as her hand encountered his hardening cock, which she rubbed just long enough to bring it to full erection before pulling her hand away. “Do you want to check me now?” giggled Sue, before following her husband’s suit and guiding Natalie’s hand up under her toga. Her fingers soon felt the smoothness of Sue’s shaved pussy, This time she allowed one finger to explore and feel Sue’s wetness before removing her hand. As if suddenly aware of what she had just done, Natalie looked across to see how Pete had reacted. Her answer lay in the very obvious outline of his hard on through his tight trousers. “Sorry sweetie, did I leave you out?” she mock pouted as she rubbed his cock through the material. He responded by kissing her deeply and sliding his hand between her legs, fingering her through the lacy material of her panties. Natalie suddenly became conscious of what they were doing in a room full of people, but looking round she saw couples all over were starting to indulge in often very blatant foreplay. Indeed right next to them Sue was on her knees in front of Bob, taking his long hard cock into her mouth. Turning her attention back to Pete she slowly undid his zip and opened up the top of his trousers so she could get her hand inside. Grabbing his erect shaft she eased it out until it was pointing straight out in front of him. Slowly she began to wank him with long deliberate strokes. She was so engrossed in this that she didn’t notice Sue moving round behind her until she felt her hands moving round to her to slip inside her open dress. She felt a sudden tingle of excitement between her legs as Sue started to tweak her nipples, and kiss the back of her neck. Pete’s eyes were bulging with delight at the sight of his wife’s breasts being fondled by another woman. His excitement grew even further as he watched Bob and Sue help each other to pull Natalie’s dress up over her head, leaving her standing there in panties, stockings and suspenders. “Now your turn” smiled Sue at him as she moved across to start undoing his shirt. He felt a little uncomfortable that Bob was helping her, especially when he felt Bob’s hard cock press against him through the material of his toga. However he made no objection, even when Bob grabbed his cock and offered it up to Sue’s mouth. Natalie couldn’t believe how much this sight was turning her on, but it clearly was. Easing her hand down the front of her panties she felt how wet she was as she started to stroke her own pussy. All around the room couples, foursomes and moresomes were getting themselves into ever greater stages of excitement and sexual activity. “Can we go to one of the small rooms” asked Natalie, who, turned on as she was, was starting to feel a bit overwhelmed by the sheer volume of sexual play going on around her. They gathered up their clothes and made their way to one of the smaller lounges that adjoined the main room. “That’s better” smiled Natalie as she pushed Pete down onto one of the sofas and knelt in front of him, taking his balls into her mouth one at a time and gently sucking them as her fingers traced up and down the bottom of his shaft. Her tongue then followed the route of her fingers until she got to the tip of his cock. Opening her mouth she lowered her head and took in almost all of his length. A loud moan caused her to stop and look up, to see that Bob had bent Sue over a table and entered her from behind. From this angle Natalie was unsure which hole he had entered, but Sue seemed to be enjoying it in either case. As she looked back at Pete he pulled her up onto the sofa, so that they were both laid on their sides with him behind. Natalie raised her right leg to make it easier for him to guide his hard cock into her soaking wet pussy. As she felt him thrusting in and out of her she looked up again at Bob and Sue, who were still testing the strength of the table. She had never dreamed before that she might be in such a situation, but now that she was it was a huge turn on. Reaching down she started to stroke her clit, while Pete continued to thrust, his movements getter more and more urgent, until the combination of his cock and her fingers drove her over the edge and her orgasm swept over her. As she climaxed her pussy walls tightened and Pete shouted out with pleasure as he started to come. She could feel his cum shooting up inside her, as he pounded into her harder and harder. Finally they both came back down to earth and realised with a shock that they were naked in a hotel with another couple fucking just feet away, and a whole roomful of people getting up to who knows what just through the doorway. They both pulled their costumes back on in silence, broken eventually by Pete “I need a drink”. “Me too”. As they stood at the bar, they grinned at each other over the top of their glasses. After all the night was not yet over.
