Erica, Judy-the-lawyer's daughter, was approaching her first semester as a sophomore at Green Cay College. She had been in Kjem's biology freshman survey course and had committed to studying biology as her major. This meant that she needed to get certified for scuba diving so that she could do the marine classwork.
She was not alone, there were two other students; Brittany and Elena, who were also incoming biology students who needed scuba certification, and Sharon, who was certified but hadn't been diving for a while and needed a refresher course. Brittany was a vivacious dark-skinned girl (she was, in fact, Brazilian), and was very petite, although she still had great curves. Elena, in contrast, was very tall and thin, with short blonde hair. She spoke with a distinct German accent. Sharon was a medium height American, quite busty with long blonde hair and a big smile. She wore no makeup and old clothes, with ratty flip-flops, and her hair was simply tied into a pony tail. Kjem knew her from last semester, she was a junior biology student, and was very smart despite her simple unassuming style.
This, with Kjem as instructor and Aud as divemaster, was the second summer semester scuba and skindiving class.
The first couple of weeks of class was taken up with the three certification students doing their book work, followed by a week of uneventful daily sessions in the West Village pool. Aud brought tanks and gear to each session and helped Kjem manage the students in the water. He made a point of reminding Aud that they were on campus and to behave herself, which she did for the most part. Everything was very by-the-book and professional, and all the students did well.
On the first day of their open-water classes they were all to met early in the morning on a Saturday at the Haulover landing dock next to Kjem's house. Aud had tanks and gear, and some lunch and drinks for everyone; she arrived half an hour before time to run things over to the Bommie Hut. She and Kjem loaded it all into the skiff and Aud headed off across the water.
Kjem met the students as they arrived, including Sharon for her refresher dives. He reviewed the plan for the day, and before long they could see and hear Aud returning in the boat. When she got to the dock, they all piled in and drove, low in the water, out to the hut.
Once at the Bommie Hut they all collected at the shallow end of the dock and assembled their gear, stripped down to their swimwear (the students all had skimpy two-piece ones, very nice), and Aud did the standard dive briefing.
Aud then continued, "OK now, Sharon, you're my buddy. Kjem, you're with Erica, and Brittany and Elena are together. But Kjem and the three of you need to stick together today and tomorrow. Sharon, for now we'll stay with them, too, and go through the basics, then we'll head out on our own. Now, check each others gear, suit up, and make sure your buddies air is on. Then follow me; it's just a giant stride into the water, just like in the pool. It's only 5 meters deep here, not much more than the pool. Once you're in, check your kit and swim out to the mooring ball and hang out on the tag line."
Everyone helped their buddies get their tanks and BC's on, masks, &c. Fins were, as usual, the awkward part for most of the girls, but it wasn't long until Sharon and Aud were ready. Aud stepped in, and when she resurfaced pointedly gave the "OK" sign. Then Sharon stepped in, OKed, and they both swam out to the tagline and floated face down, watching the wildlife of the reef below.
Erica was ready next but Kjem held her back while the other two finished getting ready and entered the water.
Floating face down on the surface, Brittany squealed through her regulator and grabbed Elena, pointing at something under the dock. They both seemed to get very excited. Aud swam over to them, got their attention, and got them to join Sharon back at the tagline. Aud popped up and gave the 'barracuda' sign to Kjem, who laughed and directed Erica to join the group in the water. As soon as he got her "OK", he stepped in himself and ushered the group together.
Signing everyone to pay attention, they all pulled their heads up and Kjem took out his regulator and told them, "OK, we'll all descend in buddy pairs to the sand at the mooring ball anchor. Circle around and adjust your buoyancy. We'll hang out for a while, let you take it all in, then start the drills."
Aud and Sharon again went first, then all four of the rest of them sorted themselves out and headed down to join Aud and Sharon. When they were all roughly circled around the line, Kjem signaled to each of them in turn to add or release air from their BC's to adjust their buoyancy. When Kjem got to Sharon and Aud, he could see that they'd taken their bikini tops off from under their BCs. Their gear was slimline and compact, for tropical water only, and so their uncovered tits were plainly visible. Kjem wagged his 'naughty' finger at them, and Aud shrugged and showed Kjem the mesh bag she had their tops stowed in. She then kicked over to the mooring line and clipped on the mesh bag; everyone could she that she was topless.
They spent almost 10 minutes getting acclimated, readjusting buoyancy and gear, and just watching the fish go by. The barracuda from under the dock came over and hung out at the periphery, and at one point a big school of bar jacks swam by. The students were all excited, but after a while Kjem could see that their breathing had settled down so he could get them refocused and go through the drills.
Aud took Sharon off to deeper water along the reef face to do some basic refresher drills and advanced skills.
Once Kjem had taken the neophytes through the routine drills for the morning, he had them all check their air supplies, then took them on a 30 minute tour around the base of the bommie. He pointed out a couple of lobsters, a big grouper and various other fish, using his fish ID slate to show the students. When they arrived back at the mooring line he had them do a slow, controlled ascent hand-over-hand up the line, then swim back to the dock. Aud had dropped the ladder, and Kjem guided them all in removing their fins and, with Aud's helping hand, climbed out of the water..
It was only when he tossed his own fins up onto the dock that Kjem realized that Aud was naked. When he climbed up, he saw that Sharon, too, was naked, lying face down on a towel in the shade in the hut. He took off his mask and gave Aud the eye as he climbed out of the water.
"What?" Aud said, "We've been back for ages. Just catching some sun."
As the others took off their gear, switched out tanks and filled out their dive logbooks, they one by one also removed their bikini tops. Aud passed sunscreen around, and they all lathered up, helping each other coat their backs.
Aud and Sharon were the exceptions. "Kjem, could you do our backs?" Aud asked, as she tossed the bottle of lotion his way. She pointed to Sharon as she lie on the towel, who nodded.
So Kjem knelt and rubbed lotion on Sharons back, starting with her shoulders and working down. When he finished around her waist, Sharon spread her legs further apart and tensed one ass cheek then the other, back and forth. The other two, who watched as they spread lotion on themselves and each other, laughed at this invitation. So Kjem shrugged and spread lotion on her ass with both hands, massaged it in, then in one swipe ran one hand deep into her ass crease and over her pussy, then swatted her ass sharply. Sharon yelped.
"My turn," said Aud, who turned around next to Kjem, presenting her back to him.
So he lotioned up Aud's back, using both hands again, and when he got to her ass he continued straight on, grabbing and rubbing both cheeks firmly. Aud moaned dramatically and pushed into his hands. When he passed lotion on one hand into her ass crease and down onto her pussy, she clamped his hand between her thighs and grabbed the invading hand with both of hers from the front, holding his hand in place and rubbing it back and forth over her pussy.
Kjem's thumb was rubbing up and down Aud's clit and vulva, so he lifted his thumb when Aud rocked backwards, it slid all the way up into her pussy.
Aud leapt with a yelp of surprize, releasing Kjem's hand and stumbling forward. Kjem wagged his finger at her, "That's what you get, harlot!"
