The school year started with Gina and Mike eagerly looking forward to their final year of school. Mike ended up having a particularly heavy load of classes the first semester. He was short a few credits and wanted to make sure the final semester of his senior year would be fairly light.
From practically the first week of classes his schedule keep Mike very busy studying, working at the lab, or meeting kids from his classes to work on group projects. He and Dana managed to keep up their personal workouts in preparation for the coming swim season, but it wasn't hard to see that the heavy class schedule was wearing him out.
Mike worked hard once the swim season started, but some of the magic from the previous year seemed to be missing. Dana knew it might be a result of his heavy class schedule, and she and the other coaches changed Mike's training plan to get those last few percentage points of performance back. Unfortunately, nothing worked.
She and Gina also kept themselves in control and spent most of the swim season fucking each other exclusively so Mike could concentrate on his studies and training. Only occasionally would Mike join them for a wild, incestuous, three-way fuck.
Dana's desire for a hard cock, and specifically for Mike's hard cock, was left mostly unsatisfied all through the swim season. She occasionally toyed with the idea of renewing her relationships with Jack or Rick, but she decided it wouldn't be right.
She guessed they would be more than willing, but she had seen both of them spending time with their girlfriends before and after practices and meets. What they had before was wild and fun, but she didn't want to be the cause of breaking up their relationships by being the other woman.
Besides, Gina had committed herself to Mike and had stopped fucking other guys. Dana wanted to honor Gina's commitment to her son by doing the same and not sleeping around. Also, Dana was afraid that if she started fucking other guys that one of them might somehow learn about her "arrangement" with Gina and Mike and expose their secret life. For the sake of Mike and Gina and for her own privacy she couldn't risk that.
The season was a success for the team if less so for Mike individually. His personal results were still very good, but they didn't quite match up to the incredible standard he set for himself the previous year. He did well enough to be an important part of the team's solid season, but Dana knew Mike was disappointed that he wasn't doing as well as the previous year. He handled his disappointment like a true leader and focused on doing whatever was best for the team and helped his teammates however he could. She was proud of the way he handled his disappointment like a real man.
The season ended, as usual, with the team's end of season party. The night was wild and loud, but the loudest cheer of all came when Mike dropped to a knee in front of Gina and asked her to marry him. As shocked as Gina clearly was, Dana was equally surprised. She smiled widely when Gina happily said yes and the place erupted with cheering.
Dana slipped out of the party fairly soon after Mike's big question. She wanted to stay and congratulate both Mike and Gina, but being around all those horny, excited guys in the drunken, testosterone-laden atmosphere of the party was more than she could resist. She was afraid if she stayed any longer she wouldn't be able to stop herself if one of Mike's teammates came on to her.
Back at the apartment Dana masturbated to relieve her pent up lust. It helped a little but she couldn't wait to fuck Mike silly. She looked forward to being able to do that often now that the season, and Mike's collegiate swimming career, were officially over. She changed and got into bed with a book figuring that Mike and Gina would be out very late celebrating their engagement.
Indeed, they did stay out very late. She heard them return and glanced at her bedside clock through sleepy eyes to see that it was nearly 4AM. She had been sound asleep and was only awakened by them talking excitedly and stumbling around the apartment drunkenly. The sounds and voices quickly moved to the other bedroom.
Dana imagined them tearing off each other's clothes and getting ready to fuck. She knew she should leave them alone on this special night, but she couldn't resist her horny curiosity. She quietly crept into the kitchen on her way toward Mike's bedroom. She didn't have to get very close to the door as they weren't even trying to be quiet and had left the door open. Dana paused in the kitchen at the sound of her future daughter-in-law moaning wildly.
Before long the bed started creaking and it was obvious Mike and Gina were fucking. They both moaned often and the fuck soon became wild and frantic. The bed creaked loudly and bumped into the wall.
Just listening to them caused Dana's fingers to find her excited clit. Dana leaned back against the kitchen wall and played with herself while listening to Mike and Gina fuck. The sounds from the bedroom reached a loud peak as they both came. Suddenly the house was washed in silence.
Dana bit her lip as she came to keep from moaning or crying out and gripped the counter to steady herself. When she finished cumming she crept back to her bedroom looking forward to giving the couple a special engagement congratulations the next night.
Since she had gone to bed fairly early, Dana was up long before either Mike or Gina and felt refreshed and well rested. She looked forward to throwing her own little celebration for Mike and Gina and hoped they didn't already have plans for the night. She went out shopping and found they were still asleep when she returned.
Mike and Gina finally emerged from their room a while later. Dana greeted them excitedly and they talked about the engagement. They chatted about possible wedding dates and locations and Dana and Gina agreed that Mike's announcement had been a complete surprise. Dana asked if they had any plans for that night and when they said they didn't she told them that she wanted to give them a congratulatory evening.
In the early evening Dana prepared an elaborate dinner for the three of them. As they ate and talked Dana could practically feel an excited anticipation fill the room. She felt her own lust growing and she hoped she wasn't just imagining the feeling in the room.
She knew some of her own excitement was caused by her choice of wardrobe for the night. She had selected a form fitting dress that dipped low between her tits. It revealed more than a little of her cleavage, especially when she leaned over. The dress came to about mid-thigh and underneath she wore only a very skimpy black thong and matching bra. It was complimented with a pair of high-heeled shoes to create what she knew was a "fuck me" look.
