Part 4 - Nude Day and Free Use
Joey and I nodded and grinned, and in unison, we entered the other's mother at the same time. They'd closed their eyes, sighing as the cocks slid in. There was no sexual Olympics this time, just some full length missionary sex under the sun. Slow and easy, we read the looks on their faces, going for intensity over speed. Neither mom had the energy for the doggy position, but continued to hold hands.
Watching from her lounge chair, Alice stood and wandered over with the tanning oil in her hand. "This is so you practice safe sex." The heat was becoming unbearable. She began spreading oil over Joey's back, bum and legs, studying each back muscle as he flexed into our mom.
Next, my sister was oiling me from heels to neck. Working her way down to our aunt underneath me, she began massaging the oil over one of Jill's breasts, squeezing and caressing it, finishing with her long nipples. With all of the oil on her fingers, she had to squeeze it hard to maintain contact. When she finally relinquished it, it audibly popped free. That simple sequence was enough to made Jill shudder. Next were our aunt's toes and legs before reaching up to the spot where Jill and I were joined 'at the hip'. It was so erotic having a third person oiling you up while fucking. I pulled my cock right out so she could grease around the pussy lips, and out again while she, spreading oil all over my cock. I doggedly plunged back in, rewarded with a slow application on my balls. It was all so surreal.
Both couples were now having protected sex, safe from the sun. Alice started oiling herself, every spot she was able to reach. She passed the bottle to me, asking me if I would do her back. She straddled out Auntie Jill's face and lowered her furry, black bush until she was rubbing slowly from chin to nose. After I finished oiling her back, Alice leaned back into me, so I reached around and groped her big, oily breasts and nipples. It occurred to me that it was the first time I'd ever truly held Alice's tits. I cradled them in my oily hands, lifting them until they slipped through my fingers. My God, she was a gorgeous creature. From below, Auntie Jill was licking Alice's pussy with the same slow, intense rhythm that I was using.
At last, Jeanine had woken from being splayed on the floor inside to come up to the top deck in search of everyone. Her cousin, Alice, passed her the tanning oil, warning her to slick herself up everywhere she could reach. "Joey can get the rest." She knew what Alice meant. Jeanine slathered herself up, taking care that her white spots were covered.
"May I sit? Would you mind, Auntie April?"
Looking up at her, Mom responded. "Not at all honey. Give me that bare pussy of yours." Mom's eyes danced. She was going to lick her niece's pussy for the first time. Sp man firsts on this trip.
Jeanine punched Joey's arm before climbing aboard Mom's lips. "I've never been fucked like that, gentlemen. Never been fucked until I lost consciousness."
"And you might not ever be again," replied her Auntie April. "I'll tell you about that late..." Jeanine kept her from finishing the sentence, covering Mom's mouth in shaved vagina. Passing the tanning oil, she asked Joey to get her back.
Jeanine was just getting into it when her brother took his oily fingers, shoving them in her ass in a single stroke.
"Jesus Christ, Joey! Didn't you guys get enough of my ass already?"
"Never."
"You'll get yours someday. I'll get you back, somehow."
The following morning, the moms were still naked at breakfast. All of the girls were a bit bowlegged and the guys were still pounding energy drinks.
"I have an announcement." Mom began. "Jill and I have decided to declare the rest of this trip Nude Week. It's been such a fun time and the thought of putting restrictive clothing back on this morning just wasn't working for us. Considering the day we all had yesterday, clothing seems unnecessary."
Auntie Jill continued. "April and I feel that no clothes would be far more fun. Our trip is half over and all too soon, getting dressed for the real world will be upon us."
"We both are awed by the beautiful bodies you have all grown into, and frankly, we want to look some more. And, you are invited to check out every inch of your moms."
"I think you're mom's a closet exhibitionist," Jeanine whispered to Alice.
"I'm cool with that," I responded. "Nude week works for me. Forced to look at 4 of the hottest women I know naked is an inconvenience I could get used to."
Mom continued. "Further to Nude Week, we have also determined that that this houseboat will be a Free Use vessel for the rest of the voyage. If anyone is horny, then choosing someone to fuck is all you need to do. Anytime, anywhere. Bend us over a table, fuck us in the lake, we ladies will spread your legs gladly if your cocks are 'up' to the task. Fuck more than one person at a the time, if you like. I know that I am certainly looking forward to trying out what Jeanine got. The idea of laying on top of one of you boys for anal while being pussy fucked from above definitely appeals to me."
"The only line in the sand is pain, unless the person is asking for it." Auntie Jill added. "But in general, we don't want anyone to go through that. To us, that's not what sex should be about. It's about pleasure. It's about excitement. I've never been so horny. It's even crazier than the old days, right April?"
"Way crazier. And fucking you all in as many ways as we can think of gets me horny just thinking about it. As I'm sure you're all aware, us old ladies haven't been getting any sex for a while now. We haven't found anyone we could trust with our feelings. So please You're welcome to fuck us! We have a lot of time to make up for."
"Whoa, wait a minute," interrupted Joey. "The old days? I want to hear more about that."
"Well, we had the same rules back in the day. There were some very erotic visits with your fathers."
"And?..."
"Joey, do you remember the day you found me tied to the bed?" asked Mom. "You were only about 5 years old at the time."
"Wait a minute. I think I do remember that. You were tied spreadeagled naked on the big bed. I totally forgot about that."
"It was the last time we were all nude when you kids were around."
"So, you guys swapped back then?" I asked.
"We had that big king sized bed that all 4 of us adults slept in. That went on right up until your fathers died, but we did start closing the doors."
"Yeah, yeah. I remember that day. The bedroom door was open and you were tied with your legs wide open. And then, my Dad climbed on top of you."
Auntie Jill broke in on the conversation. "Ah, the good old days. I loved coming to visit you guys. Sure, you had the backyard pool, but it's the bed that I remember best. Do you remember what happened next?"
"Hmmmm... I remember wondering why Auntie April and my Dad had different colours of pubic hair. Or any pubic hair, for that matter. I knew I didn't, so why did you? Dad was bouncing on top of you, Auntie April and you were screaming."
