The morning that Karina and Stacy were coming over to use my pool was another beautiful day outside. I also knew that it was going to be a very difficult day because my teenage lover would be within feet of me and I would be unable to touch her. To make matters worse I would have a second nubile young girl prancing around my pool nearly naked.

Around 10 AM I again heard the doorbell ring when open the door and then in front of me stood my dark-haired Angel, Karina and another beautiful teenage girl, this one with long flowing blonde hair and bright blue eyes. Karina had on the same clothing that she had worn the day before but this time she on the white bikini and a small white crop top that covered her bikini top.

Stacy had on similar clothing except her top was a light blue T-shirt and a pair of tan short shorts. Karen entered the living room first followed by Stacy. Karina introduced Stacy to me and I shook her hand and made her feel welcome. I gave Stacy the same tour of the house that I had given Karina on her first visit. Stacy was kind of quiet at first but as she grew more comfortable with me, she started to open up. Two girls chatted as they walked out of the as they walked out to the pool. I had chosen to wear a pair of board shorts and a tank top that day and whilst Stacy was looking elsewhere Karina winked at me seductively. I spent a few more minutes puttering around the kitchen and then decided it was time to go to the pool. By the time I arrived outside the two girls had stepped out of their clothing, and exposing their bikinis. Their bikinis matched string for string except for the color Karina had chosen to wear white while Stacy had worn red.

If I hadn’t seen Karina in that bikini before I am sure I would’ve had trouble keeping my face neutral. Stacy’s bikini, like Karina’s, left little to the imagination and the color looked very becoming on her. Several times with course of the next couple of hours the girls would jump into the pool and swim a few laps and climb out. On one such occasion I happen to be looking at Stacy and could swear that her bikini bottom had moved in such a way as to expose the lips of her vagina. I would also swear that she either had no pubic hair or very little on her Mons.

Stacy did have a very good tan. If I had to guess I would say her breasts were just larger than a mouthful but held the promise of future development. A few times a slight breeze would kick up and both girls’ nipples would harden. A couple of times I noticed the two girls smiling and whispering to each other as they stared at me above their sunglasses. I remembered what Karen had said to me about Stacy and wondered how long it would take to seduce Stacy. Stacy was only about five foot one and very waif like in her build. Slim in the waist as well as the hips, her small tight ass just begged to be held in my hands.

A late lunch was followed by a couple more hours by the pool and was time for the girls to the home. It had been very hard looking at two of them and not being able to touch either of them.

The next day Karina came over earlier than normal because she was in need of my cock. She explained that Stacy would be over just before lunch as she had something to do that morning. We were both ready to fuck and didn’t make it to the bedroom before I had my cock buried in Karina’s tight pussy. Just about the time we were getting dressed after a quick shower, we heard the doorbell ring and I rushed to the door to see who it was.

I greeted Stacy and let her into the house. We exchanged a few words then we walked out to the pool. I saw that Karina was in the water laying on her back, wearing a dark blue bikini instead of the one she had arrived in. I knew that her last bikini was balled up and hidden in her bag, I had fucked her with the bottoms still on and must have soiled it with our juices.

Over the course of the day the two would occasionally put their heads together and then giggle and then Stacy would look at me and then at my semi hard cock the turn her head and look elsewhere. Karina had told me after we had fucked that she was getting Stacy ready to be my next teen lover. Karina wanted Stacy to feel the same things that she had felt her first time with me. I just said that if it was what Stacy wanted then I would be happy to be her first man. Karina had admitted before that She and Stacy had made love to each other.

Friday came with bright sunny skies and warm temperatures. I had explained to the girls that I had work to do before they arrived and they both understood.

I caught up my work, then did laundry and cleaned the house. I spruced up the yard and the cars and sat down later to rest and take a nap.

I told both of them that I had to take a short business trip and that I wouldn’t be able to call or text them while I was gone. As soon as returned home from my trip I texted Karina and she came over. As soon as she was in the door, she plastered her body to mine and reached up for a deep kiss. I swept her into my arms and carried her to the couch and together we stripped out of our clothes and started to make love too each other. As I knelt behind her and drove my cock into her pussy, I dipped my fingers into our combined juices and gently worked my index finger into the tight ring of her ass. I heard her gasped as my finger sunk in past the first then second joint.

This anal intrusion caused her already tight pussy to tighten even more and I heard her say in a breathless voice, “God that feels so weird, but good.”

I gently moved my finger deeper into her tight rectum and after a minute or so of that I started to slip another in besides the first finger. After a few more minutes I had brought Karina to another orgasm and now had three fingers wedged deep in her tight ass. I continued to work my cock in and out and at the same time as I drove into her pussy, I would also push my fingers into her ass.

By this time, I was very close to coming and as I let myself come, I pushed a fourth finger into Karina’s ass. This further intrusion pushed her over the edge and she let out a loud scream as her next and biggest orgasm washed over her body. I watched through half-closed eyes as Karina came down from her orgasm and slumped forward to lay on her stomach. As she fell forward my fingers slipped out of her ass and I also slumped forward and lay partially on top of her.

After I had caught my breath, I slipped off of Karina and sat on the floor and waited for her to wake up from her nap. She slept for half an hour then started to wake up. First her eyes half opened then as they did, she smiled at me and indicated for me to give her a kiss. Her lips were moist and soft as they toughed mine in a tender kiss. She sat up and I joined her on the couch and we snuggled for a few minutes.

“Can I ask you a question?” Karina asked as her fingers played with the hair on my chest.

“Sure, ask away.”

“Would you like to fuck my ass?” Karina asked as she looked up at me.

“Yes, I would, but you must understand that I have a bigger than average cock and it would be difficult for you, we would have to prepare you in advance for the experience.”

Karina was quiet for a few seconds then asked, “What would we have to do.”

“The first step is to train your rectum to accept something large in past the tight ring of muscles, which is done by using a series of butt plugs that get larger as we make progress in training your ass.”

Karina was quiet for a while then said, “Okay, when can we get started.”

“Right now, if, you’re sure.”

Karina smiled at me and said, “If having your cock in my ass feels anything like your fingers then I want to try it.”

“Okay, but once we start you need to follow my instructions to the letter and if at any time you want to stop, please tell me.”

Karina agreed and we held each other for a few more minutes then, I got up and led her to the master bath and we cleaned up. I walked her to the master bed and instructed her to lay on the bed face down and with a couple of pillows under her hips. While we were cleaning up, I had told her the instructions and she repeated them back. I was going to put a small butt plug in her ass and she had to keep it there the rest of the day. We would repeat this every day until she was able to take and hold a large butt plug. The last step would be to remove the large plug and replace it with my cock. I had also told her that is possible she should sleep with the plugs in.

I admired her ass as she lay face down with her tight ass elevated. I had laid out the four different sized plugs and applied some lube to the plug then her ass and kissed her left ass cheek and gently, and slowly worked the plug into her tight rectum, and when her body encountered the larger flange of the plug I kissed her lips, our lips intertwined. I broke the kiss and then whispered, “Take a deep breath and relax.”

Karina took a deep breath and as she began to let it out, I heard and felt her relax her body. As she relaxed, I worked the plug past the flange and watched as the base of the plug rested at the opening to her tight anal ring. I heard her gasp as the feeling of having the plug in her ass. “It feels so strange, like I need to take a shit, but it feels kind of good to.”

“Good, now let’s see if you can walk and keep it in at the same time,” I said, As I reached out to help her off the bed. She first got on her knees and reached around and felt the plug in her ass then slipped her hand into mine and got off the bed. As she stood up straight, she gasped again as the butt plug changed angles in her rectum. She started to walk forward and as she did, she gasped again and reached around and felt the plug in her ass. She assured me that she would keep it in for the rest of the day.

We had lunch then spent some time by the pool and then I took a few more pictures of her and a couple of her with her ass filled with the butt plug.

We started to make love again in the afternoon and this time she was on top so I could take a few pictures and I also used the camera’s video function to take a few minutes of footage of her tight pussy sliding up and down on my cock. Part of the time she was playing with the butt plug in her ass. We came together, Karina screaming in pleasure, myself grunting as I filled her pussy with my cum.

We rested in each other’s arms, enjoying the afterglow of mutual pleasure. Karina moved so that she was laying on top of me with her face near mine. “Stacy knows that I’m not a virgin anymore.”

“Okay, how does she know and does she know who took it?”

“We were sort of fooling around with each other and as she started to lick my pussy she noticed that I could take three of her fingers in my pussy. She guessed the rest and wanted to know who I had done it with.”

“Did you tell her it was me?”

“No, of course not, but she believes that it was you.”

I thought for a minute then asked, “How does that make you feel and will she keep her mouth shut if she indeed knows.”

“Stacy is my best friend and I know we can trust her. She and I have been making out with each other for about a year. I want her first time to be as great as mine was. Besides, I love her like a sister.”

“How would you feel if I did make love to her.”

Karina had a thoughtful look on her face for a minute then said, “I would love to share her with you, maybe even watch as you fuck her then have her watch as you fuck my ass the first time.”

We talked about Stacy for a while longer and I agreed that Karina could ask her how she would want her first time to be and I would be willing to be her first as long as she kept this all a secret.

It was late in the afternoon and it was time for Karina to leave. On her way out she turned to me and said, “I’m going over to Stacy’s tonight, with your permission I will ask her about how she wants to lose her virginity.”

I thought for a moment then responded, “Okay, but remember she has to swear to secrecy, I know you can keep a secret but I still have a lot to lose, and if we get caught, we could never see each other again.”

“I’m going to tell her how I lost my virginity but not who and see how she reacts to that. When we come over tomorrow, I will somehow find time to get you alone and tell you what she said.”

“That sounds like a plan, promise to keep that butt plug in unless you need to use the restroom.” I playfully slapped her ass as she headed for the door. She turned once more and give me a kiss, and then she was gone. It occurred to me that Stacy might find out about the butt plug and ask why Karina had it in her ass. I trusted Karina to make the right decision about that and our future relationship.

I spent the rest of the evening puttering about house, I had a couple beers, and caught up on some TV then went to bed.

The next day arrived with clear warm skies. I worked until I heard the doorbell ring around 9 AM. Somehow, I knew that it was Karina coming over early and that Stacy would be a long about 10 AM. I put my work away and walked to the front door to see who was. As I thought, it was Karina standing near the door dressed as usual and a pair of shorts and a T-shirt. I let her in the front door and closed it behind her.

We hugged each other and shared a deep kiss. It was Karina that broke the kiss and said, “I talked to Stacey last night, I told her about how I lost my virginity and my story left her horny. We started to fool around and she noticed the butt plug still in my ass. Without telling her your name I explained why I had the plug in my ass.”

“And what was her reaction?”

“She wants to lose her cherry badly, and then she wants to see what it feels like to have a cock in her ass. I have to tell you that as she was eating my pussy she started to play with the plug in my ass and as she did I had a very strong orgasm, not as good as when you’re fucking me but almost as good.”

“That’s great to hear,” I said as I reached down and squeezed her ass and found that she did have the plug still firmly embedded in her ass. “Are you ready for a bigger plug, or do you want to wait?”

“I came over early so we could try the next one,” replied Karina as she again kissed me.

“Stacy is sure to notice the bigger plug and then she’ll know it was me that took your virginity. Will she keep our secret or maybe join us?”

“She knows that it was you or rather she guessed that it was you and she told me that she would like you to be her first lover. I didn’t agree or disagree with her, but I did tell her that she had to make her own decision and ask you herself.”

“So, Stacy knows and she might ask me today?”

“I’ve known Stacy most of my life and I am willing to bet that she will ask you. I know that it makes me very horny to think that I might be able to watch my best friend make love to you for that first time.”

“We’ll see what the day brings, now we have just enough time to see if you’re ready for the next size butt plug.”

“Okay, let’s plug my ass again,” Karina giggled as we walked arm in arm to the bedroom and the supplies I had laid out on the bed. I took me half an hour to loosen up Karina’s ass enough to seat the larger plug. As she stood up, she gasped and reached out to take my arm. “God, I almost came then.”

I helped her with her Bikini bottoms and when they were in place, I had her turn around and it was then that I noticed the slight bulge at the rear of her bottoms. “Stacy is going to see the bulge unless you wear your shorts or remain seated or on your back.”

“Well, I knew that she might see it so that’s why I told her about my first time and how great it was. Let’s keep an open mind and let her make the first move,” Karina giggled and started to walk out of the bedroom. It was interesting to see her ass wiggle with the bigger plug lodged in her tight ass.

Karina and I sat on the living room couch until we heard the doorbell ring. Karina had put her shorts back on but left her shirt off. I answered the door and there standing on the porch was Stacy. Her long blond hair was loose and gently swaying with the wind. Her blue eyes and pink lips were showing a smile. She was dressed in the usual pair of tan shorts and a white T shirt.

“Hi Mr. A. is Karina here already?”

“Yes, she is, come on in, the pool and the sun are waiting.”

“Thanks Mr. A.”

Stacy saw Karina sitting on the couch and walked over and the pair headed out to the pool, talking in whispers as they walked. I closed the door and followed them out to the pool. Over the next hour the two girls talked in whispers before they finally got into the pool. During that time, I made some iced tea and added five drops of M-133 to both girls’ drinks.

Stacy was the first to remove her shorts and shirt and revealed a small sheer white bikini that just managed to cover her nipples and her pussy, the rest of the bikini was just strings. I knew that Karina was wearing my favorite Red one piece bikini, I also knew that this would either shock Stacy or get her horny.

Stacy was swimming lazily in the water as Karina stood up and began to remove her shirt and revealed the two vertical red strips of cloth that ran down into her shorts. When Stacy got her first look at the suit Karina was wearing, she stopped and stared at her friend. Stacy just stood in the pool as Karina shimmied out of her shorts to reveal the rest of her suit.

“My God, you really bought it.”

“Yes, and it makes me feel so wicked and horny,” Karina giggled as she ran her hands over her suit and body.

I was sitting across the pool watching the two girls, trying to remain calm, but failing at the effort. I knew that as soon as Karina turned around, Stacy would see the base of the butt plug in her ass. I steeled myself for the expected barrage of questions that were sure to come from the two young girls.

Karina walked to the edge of the pool and slowly slide into the water, being careful not to expose her ass too soon. We had discussed this and decided that we would wait for a few minutes and see how Stacy reacted to the suit first. Karina would talk to Stacy and then get out of the pool first, exposing her ass and the plug and then we would play the rest by ear.

The two girls talked and held each other for a few minutes and then the swam a few laps and talked a bit more. Karina finally got tired and started to walk to the pool stairs. As her butt came out of the water the plug in her ass became clearly visible. Stacy looked at her ass and gasped, a look of shock crossed her face.
