If you have been following my adventures, you know that I am Tom, a 42-year-old divorced man with a hot 17-year-old daughter, Mandy, and her equally hot best friend, Janice. My previous stories chronicled the first two weekends when I first accidentally saw my daughter naked, which led to her and Janice seducing me.

Over the next couple of weeks, the sex got wild and crazy to say the least.

Well, the rest of the summer continued in much the same way. During the week, Mandy and I tried to live a normal father-daughter relationship, but the weekends were almost solid debauchery for the three of us. The only exceptions were those in which Mandy spent weekends at Janice's house, mostly because of their family pool.

All that meant, though, was that I was celibate, while Mandy and Janice feasted on each other's bodies without me. They had to be a little quieter about it because Janice's parents had no idea the girls had become lovers. When they were here at my house, no one needed to hide a thing.

Unfortunately, the calendar has a way of moving faster than we would like. In just a couple of weeks, Mandy and Janice will be starting their Senior year in high school, with all that entails, including hard work and lots of time visiting colleges and submitting applications.

Our wild weekends will certainly have to be severely curtailed as a result.

I wanted to have a fitting send-off to the summer, so I arranged for the three of us to spend a long weekend at a clothing-optional resort in Mexico. Janice had to do a little convincing with her parents before they gave their okay, but she convinced them it was a beautiful family resort, and it would just be a last hurrah to summer.

I booked a two-bedroom suite, although I was certain we would only use one of them. The unit had a full kitchen, a living room, and an outdoor deck with a hot tub.

On the flight down, I took the middle seat, so I could have my beautiful girls on each side of me. They were both dressed in very mini shorts, tight tops with bare midriffs, and flip-flops. Somehow, they managed to look delightfully sexy and even innocent, without looking like the tarty little sluts they both had become!

Mandy had the window seat, and Janice had the aisle. I spread a blanket across the three of us, so I could diddle both girls without it being obvious. At least I hoped it wouldn't be obvious.

I had one hand each stroking and caressing the thighs of my two little sluts. They both opened their legs so my hand could stroke their crotches through their little shorts. Mandy, being in the window seat, was a little more hidden, and I realized she had just unsnapped and unzipped her shorts, pushing them down to mid-thigh.

Her naked pussy was suddenly beneath my fingers, which meant she either pushed her thong down as well as her shorts, or she never bothered with a thong in the first place.

I whispered to her, "Did you push your thong down just now, too?"

She giggled quietly. "No, Daddy, I didn't bring any underwear on this trip at all. Neither did Janice. We talked about it and realized underwear this weekend was a waste of time and space."

My fingers probed my daughter's wet, bald snatch now. I loved how dripping wet her little cunt was. I pulled my hand from under the blanket and made her watch as I licked my wet fingers clean. I slid my hand under the blanket again and got my fingers nice and wet. This time, I leaned across my seat and offered my Mandy-juice-coated fingers to Janice to savor.

That immediately caused Janice to undo her shorts and push them down as well. Now I had two juicy cunts to finger and rub. I always love teasing my two teens, and now I wanted to see if they could keep quiet on this crowded plane as I worked to make them both cum.

The two of them were wriggling in their seats. I was starting to smell their aroused cunts, and began to wonder if other passengers might notice it as well. My fingers were furiously working their clits, and I could hear little mews of pleasure coming from them as they tried so hard to keep quiet!

Almost simultaneously, their bodies stiffened. They arched their backs, and their breathing got heavy and rapid as orgasms overtook them both. I could only imagine how wet the seats under their cunts must be by now.

My fingers stopped, and they slowly relaxed. Each of them leaned toward me, kissed my cheeks, and whispered, "Thank you, Daddy!" to me.

Suddenly, two hands were undoing the snap on my jeans and were tugging down my zipper. My cock was extracted from my boxers, and I felt one hand begin to stroke my shaft, while the other hand cupped and massaged my balls.

Payback can be a bitch, and these two young sluts knew oh so well how to push my buttons! Janice gently squeezed my balls, and Mandy expertly stroked my cock. It would not take long at all to complete their magic.

I moaned softly as the cum surged from my balls and spurted all over Mandy's hand. She covered the top of my penis with her hand, so my spunk coated her fingers and palm. She pulled her hand from under the blanket and made a show of licking every drop from her fingers and hand.

I offered my wet hands to each of them so they could taste themselves on my wet fingers.

There was movement around the cabin now as we approached Mexico. The girls pulled their shorts back up, and I rezipped myself. Somehow, we seem to have done all that without detection by other passengers or crew, thank God!

The plane landed. We collected our luggage and spotted the van with our Hotel name on it. We boarded, and before long, we were dropped off at the front desk to check in. I had booked a 2-bedroom suite for us, but the second bedroom was unlikely to be used much unless we invited some new folks to join us.

Mandy and Janice were thrilled with our accommodations. We had a beautiful balcony overlooking the pool, and the beach and ocean were just beyond it. It was sunny and warm, so all three of us were anxious to hit the pool and beach.

While the resort was clothing-optional, you were required to wear something inside the hotel and at meals. Complimentary robes were provided, so we stripped naked and donned a robe before heading out. The girls wanted to go to the beach first, rather than the pool, so we grabbed beach towels and headed outside.

As we passed the pool, we all made sure to check out the people around it. Some were wearing bathing suits. Some women were topless, and others, men and women both, were naked.

The beach was less crowded, and it appeared virtually everyone was naked, which suited my two sluts just fine. We grabbed three lounge chairs and removed our robes.

There are few sights more beautiful than two lovely naked young women, tanned and toned, their brown skin in luscious contrast to the white sand of the beach and the blue of the ocean. I couldn't take my eyes off them. Because they often sunbathed naked at Janice's pool at home, they had no tan lines. Their breasts were exquisite, with luscious pink nipples. Their bodies were toned and perfect. Their pussies were utterly soft and smooth, with not a trace of hair or stubble. Yesterday, they had their pussies waxed in preparation for this long weekend.

I needed to focus my attention elsewhere, as staring at them was stiffening my cock quite rapidly. They noticed and giggled. "Are we doing that to you, Daddy?" Janice asked me.

"You know you are, you naughty little sluts!"

"Want to watch us put sunscreen on each other, Daddy?"

I sat up and draped my beach towel over my crotch, so I could watch them slather sunscreen all over each other, paying special attention, of course, to their most private parts.

As they did so, I noticed some nearby people were also checking them out.

Most notably, a black couple, who appeared to be in their 30s, were paying close attention to Mandy and Janice as they sensually applied sunscreen to each other. When I told the girls they were putting on a show, they looked over at the other couple and smiled.

The man was about 6' tall, quite dark, almost ebony, really. His cock was flaccid, but even so, it was huge. His entire cock and balls were shaved, which made him look even bigger. His lady was more of a mocha color, about 5'5", slim with beautiful, firm breasts and dark, almost black, nipples. She was mostly shaved smooth, except for a tiny landing strip of hair just above her slit.

The girls finished their applications, stood up, and walked over to the other couple.

Mandy held out her hand to the man.

"Hi, I'm Mandy. This is my best friend, Janice, and that is my dad over there. Don't worry about him. The three of us do EVERYTHING together," she said with a naughty grin.

"I'm Marcus, and this is my wife, Wendy. It's a pleasure to meet you. As you noticed, we both enjoyed watching you slather on that sunscreen. We don't have to worry about that as much as you, as you can see!" he said with a laugh.

I stood up and walked over to meet them myself.

"I'm Tom," I said as they introduced themselves.

"We just arrived," I told them. "We're hoping to simply get some sun and have some fun before the girls head back to school."

Marcus said, "Well, we'd be happy to help share in your fun if you are willing, no matter what direction that fun may take."

"Just the way you phrased that makes me think we are looking along the same lines," I said with a knowing smile. "Let me be blunt. Are you swingers?"

Marcus laughed. "Well, that might be too extreme a name for us, but especially on vacation, we enjoy getting to know some new people intimately, you might say. And from what I am seeing and hearing so far, this weekend has a lot of possibilities!"

Wendy put her arm around her husband's waist. "I love how Marcus indulges me and lets me have fun with whomever I want on vacation." She reached out with both her hands and caressed Mandy and Janice's cheeks. "I hope I'm reading this right," she said softly to the girls.

Mandy shivered just a bit, and her nipple stiffened. "Oh, yes, Wendy. We want whatever you guys want, right, Daddy?"

"Oh, yes, Baby," I replied. This is getting off to a very nice start."

We continued chatting and getting to know our new friends. Check-in was at 4 pm, so it was almost dinner time already. We agreed to meet Marcus and Wendy in the dining room at 6:30. We'd have dinner together and see where things might lead, although I think we all felt it would lead to the bedroom.

The girls showered, together, of course. I could hear them giggling and moaning in there, so I knew they were pleasing one another. They were both insatiable when it came to giving and receiving orgasms.

They came out naked and wet and proceeded to dry one another, as I took my turn in the shower. When I came out, the girls were dressed in sexy little sundresses and sandals. The dresses barely came to mid-thigh. They were putting on their makeup as I dressed in dress shorts, a collared golf shirt, and sandals.

We went down to the dining room. Marcus and Wendy were waiting for us in the lobby. Marcus was dressed similarly to me, and Wendy wore a miniskirt, a top, and heels. There were hugs all around, and we proceeded into the dining room.

The first thing we did was order margaritas all around. Fortunately, in Mexico, no one paid much attention to the drinking age, so nothing was said about Mandy and Janice having cocktails. A toast to a fabulous weekend was made, and then we ordered dinner and a nice wine.

Over dinner, our conversation got more and more revealing. Marcus and Wendy knew enough about my relationship with Mandy and Janice that there was no reason to hold back. They actually seemed very turned on by the stories of our shenanigans together.

Mandy and Janice shyly admitted that they had never been with a black man before, but they were so anxious to find out if the stories were true. Wendy smiled and told them she would share Marcus with them if she could have them as well. The girls blushed and told her they loved pussy almost as much as cock.

I looked at Wendy. "What about me? Don't I get some nice chocolate pussy as well?"

She laughed. "Of course you do, Tom. But do you think you can handle it?"

"If I can fuck you, while I watch Marcus enjoy my daughter and her friend, I will be in absolute heaven!"

The wine, the margaritas, and the conversation were getting us all very horny. We decided that tonight, we would go back to our suite, and if all went as well as we hoped, we would use their place tomorrow.

We got in the elevator and headed upstairs. Once in our suite, Marcus looked at Mandy and told her, "Come here, girl!"

She walked shyly to him, and he pushed on her shoulders. She dropped to her knees and unbuttoned and unzipped his shorts. She yanked shorts and boxers down in one motion, and his cock, now more than half erect, sprang into view.

"Oh my God, you are fucking HUGE! Janice, come here and help me with this."

Without missing a beat, Janice pulled her sundress over her head and dropped naked on her knees beside Mandy. They greedily began stroking and licking this massive shaft until he was fully erect. He must have been 9" long and incredibly thick.

As I watched, I came behind Wendy and nuzzled her neck. She leaned back into me, and I pulled her top over her head, baring her breasts. My hands fondled them, pinching and squeezing her almost black nipples. She reached behind her and unzipped her skirt. It fell to the floor, so she wore only a tiny red thong.

I slipped my hand inside the front of the thong and felt her wet pussy, as we watched her husband rub his massive cock over the faces of my daughter and her friend.

After a while, Marcus pulled Mandy to her feet and pulled her dress over her head. Both girls were nude now, and he led them to the bed. He lay on his back, and Janice straddled his face as Mandy positioned herself above his massive cock. She slowly lowered herself onto it. She couldn't believe how thick he was. Never had her cunt been stretched like this. Inch by inch, she pushed down, impaling herself deeper on his member. Janice was rubbing her cunt over Marcus's face, and his tongue probed her wet hole.

I pushed Wendy's thong down, so she was nude now as well. She turned around and frantically stripped me, pulling my shirt over my head and then yanking down my shorts. "Fuck me, Tom! Throw me on the bed and fuck me next to your slut daughter!"

I did just that. Threw her onto her back next to her husband. I rammed my cock hard into Wendy's cunt. Next to me, Mandy had taken at least half of Marcus's cock into her cunt and was bouncing up and down on it.

"Oh, fuck, you're so big. It hurts, but I fucking love it! Fuck me, Marcus. Make me your little white bitch!"

Her tits were bouncing as she rode him as best she could. Wendy had her thighs wrapped around my ass as I plowed her hole. Janice was moaning in pleasure as Marcus's tongue used her sodden snatch as his watering hole. The bed creaked as the five of us used it like the bed in a whore house.

Janis shrieked and came all over Marcus's mouth and face. She lifted herself from him and immediately lowered her cunt onto Wendy's face to clean.

"Fuck her, Daddy! Fuck this bitch, while she cleans up my snatch," Janice ordered me.

Mandy bounced harder on his cock, as she started to cum and cum. Marcus stiffened and flooded my little girl's cunt with a massive discharge of semen. I followed suit, filling his wife's pussy with my own creamy load.

The bed was soaked with cum. As we came down from our sex high, Marcus and Wendy thanked us for an amazing evening. Marcus told us they were going to go back to their room for the night. Otherwise, none of us will get any sleep, and we all want to enjoy tomorrow.

They dressed, and we said good night with kisses and hugs. Our bed was a cum soaked mess.

"Well, girls, now I know why we got a 2-bedroom suite. Let's sleep in the other room. Housekeeping will give us clean sheets in the morning!"

We headed to the spare bedroom. As we got into bed, Janice said to me, "Daddy, I didn't get any cock tonight, only tongues. Fuck me, please, Daddy?"

Who am I to disappoint my surrogate daughter?
