"Sure," Mike answered as Wendy took his hand and they slowly moved their way through the crowd and onto the dance floor. They made a small space for themselves on the dance floor and began slowly dancing to the music. The song wasn't necessarily a slow song but they each still held their drinks and the floor was so crowded that there wasn't much room to do more than sway. They finished dancing to the song and stayed on the floor for another couple of songs before the DJ began playing a slow song.
All around them couples began literally melting into each other's arms as their slow dancing generally became either a long, drawn out kiss as they swayed back and forth or something a little more explicit with hips and crotches grinding together very suggestively. Mike and Wendy remained one of the very few couples on the floor to actually dance together. They each still held their now empty glasses in one hand so Mike placed a hand on her side and she draped her free arm over his shoulder. As they danced for the rest of the song they generally kept a small space between them but Mike could feel a growing knot in his stomach and a certain tingling again in his cock at being this close and dancing with her. A couple of times they rubbed together as they danced and each time Mike felt an electric spark of excitement surge through him.
When the song ended they worked their way off the dance floor and moved back to the bar. After ordering another round they stood off the dance floor and watched the dancers. They chatted some while they finished their drinks and then moved out onto the dance floor themselves. They spent the next while either dancing or resting on the side of the dance floor and periodically going to the bar for more drinks. Mike had slowed his drinking some and was managing to maintain a nice buzz, but Wendy had kept drinking at a faster pace than on either of the previous two nights. A few rounds later Mike could tell that she was very drunk and having a ball dancing.
Mike had enjoyed her gradually growing drunkenness because as she got more and more drunk she became more and more physical on the dance floor. Mike knew in the rational side of his mind that he should be ashamed of himself for taking advantage of his mom's drunken state, but he was so horny from the past couple of nights and the whole atmosphere of the club seemed so very sexual that he couldn't resist. Besides, he wasn't doing anything as obvious as groping her or doing some of the things other couples were doing. He merely was responding to her actions even if it meant that his hands would sometimes slide down onto her hips as they danced or that he would occasional rub his crotch against either her ass or her crotch as they danced.
The crowd seemed to somehow grow throughout the night even though it felt like it was impossible to squeeze one more person inside the room. After Wendy finished another round of drinks they moved back out to the dance floor and resumed dancing. Mike was keenly aware that as she danced in front of him with her back turned she was rubbing her ass constantly back and forth against his crotch. The sensation soon had his cock growing stiff in his pants as he began to move his own hips from side to side to accentuate the sensation.
For the next song the DJ played another slow number and Wendy spun around and wrapped both of her arms under Mike's arms and around the middle of his back. He followed her lead and placed his hands on her hips as they began dancing closely together. Wendy pulled him even closer and turned her head to whisper into his ear. As they continued to dance pressed tightly together she began to speak.
"Mike, what I am about to say is hard for me so please let me finish and don't interrupt. Last night I came very close to doing something that I never imagined wanting to do. In fact, since this trip has started I feel like we have been moving very close to a fine line that should probably never be crossed."
She stopped talking for a moment and Mike could feel the knot in his stomach tighten in hopeful anticipation of what she might say next.
"I can't deny it any longer," she continued, "I know it is wrong. But I also know that I want it very badly." She paused again and Mike could almost sense her struggling to find the courage and the right words to continue. "It would never have to leave this ship, but for the rest of this cruise I don't want to have to be your mother. I need to act on these feelings... I need... you."
When she finished she pulled away from Mike and looked him straight in the eyes. He could see that her eyes were glassy with tears as making her confession had obviously been very emotional for her. They stood staring into each other's eyes for a few more moments before Mike answered her plea by moving his lips to hers and meeting her in a soft, slow kiss. At first their kiss was tender as their lips pressed together and softly moved back and forth over each other, but it soon progressed to something more lustful.
Wendy parted her lips first and Mike immediately responded as their tongues met and began a dance of their own. Wendy's hands moved up Mike's back and she began running her fingers through his hair as they wildly kissed in the middle of the dance floor. The people surrounding them didn't even look twice at what to them was just another couple making out, but Mike wouldn't have cared at that moment if every person in the place was staring. He was about to live out a fantasy more wild and forbidden than anything he could ever have imagined and something which until three days ago had never crossed his mind.
As their kiss continued Mike couldn't resist any longer and he let his right hand slide down her hip and around her until he was caressing her ass through her dress. He could feel her moan into his mouth as they kissed. Her ass felt amazing through the sleek material of her dress and he loved feeling it pass under his fingers as his hand slid up and down her ass slowly.
They continued like this for a while longer. Mike couldn't tell if it was still the same song or if ten songs had passed since they started kissing as he was so wrapped up in what was happening. Wendy was the one who finally parted the kiss and took hold of his hand. Without a word she turned and began to cut a path through the crowd. Although she hadn't said anything to him Mike knew exactly where she was heading.
After they finally exited the club they walked hurriedly down the corridors to their cabin. They walked, holding hands, without saying a word. When they got to the door Mike keyed it open and they quickly moved inside and shut the door behind them. Once inside they resumed their wild embrace and this time Mike let his hands roam freely over her back and ass. The heat, the passion, the wantonness between them was beyond anything that Mike had ever felt before. As they eventually parted their kiss Mike began to speak but Wendy put her finger on his lips and said, "No talking. Just act on what you feel."
