We were all packed and ready to go when Annie drove up precisely at 4:00 on Friday. I introduced her to Mom, and Mom exclaimed, “You are much too pretty! No wonder the boys are so interested in your class.”
“Mrs. Lange, you are much too pretty to be the mother of teenagers!”
I interrupted, “OK, knock off the buttery stuff. Let’s get going.” I drove with Chuck up front in the passenger seat. We weren’t out of town before they were calling each other Linda and Annie. They talked the whole 2 hours to the hotel. We checked in and were shown up to our rooms. The hotel was very nice, and the rooms were large. In our seventh-floor room, I asked Chuck to try and get Mom away so Annie and I would have some time together. He grinned and said it would be his pleasure. We stowed our clothes and knocked on the connecting door. Mom opened her side, and we walked in to look at their room, an exact mirror of ours. Annie was hanging her clothes as I looked in their bathroom. She gave me a wink and touched her pendant. I almost groaned. Her eyes sparkled. We talked about dinner and decided to eat at the hotel that night. Mom called down and made a reservation for 8:00. We had two hours, and Mom asked if anyone of us wanted to look around the shops with her. Chuck told her he would be glad to, and I said I wanted to go look at the auditorium across the street. Annie took the hint and said she would go with me. She grabbed her coat and purse. We went out through my room and shut the connecting door on my side. She giggled and gave me a hot kiss as I got my coat.
“Mike, I would love to put you on that bed and fuck you right now.” I told her that it would be a fight to see who put whom on the bed. We kissed again and went down to the street.
We walked over to the auditorium and looked around for a few minutes. It was pretty empty except for some booths set up for the exhibits and some tables for registration. I asked Annie if she wanted to go back to my room, and she nodded vigorously, her eyes bright. We hurried back to the hotel and up to my room. We were frantically kissing and trying to get our clothes off, both of us frantic to get at each other. After I tore her clothes off, I threw her on the bed, and we were all over each other. I was kissing her all over, and she was trying to suck my cock. Her pussy was pretty wet, and she asked me to fuck her hard. I slid into her quickly, and we were bucking hard against each other. We didn’t last too long before we came. She was laughing and smiling at me as I kissed her feverishly.
“I guess we were pretty horny, honey.” She hugged me, and we kissed a long, sweet kiss. I told her that I loved her, and she told me of her love. She sighed and said we had better get dressed. She went into the bathroom to wash her pussy off, and I followed to help. I’m afraid I wasn’t much help, and she almost let me take her again. She pushed me away, then ran back into the room and picked up her bra to put it on, fiddled with it a moment, and took it back off. She examined the clasp and told me I had torn the eyes off when I ripped it off her. She looked at me accusingly, and I apologized. Still naked, she went to the connecting door and slowly opened it and looked into Mom’s room to make sure the coast was clear. She gasped and said loudly, “Oh! Please excuse me!” I was at the door in a second and looked in to see Mom on all fours, facing our door, being fucked by Chuck. Her face was beet-red, and she was in shock. Chuck was frozen in mid-stroke.
I said, “Oops! Sorry, Mom. We thought you were shopping.”
The door was open far enough that Mom could see Annie’s bare shoulder and hip. Of course, I was naked. Mom’s eyes tried to comprehend what she was seeing, and then comprehension came to her. She asked me almost calmly, “How long has this been going on, Mike?”
I blushed and said softly, “A little more than two months.”
“Was Kathy in on it?” I nodded.
“You could have told me, Mike. I would have understood.” She was truly disappointed in me.
My heart hit bottom. “I’m sorry, Mom, but we thought it would be too dangerous for Annie if you disapproved.” It was a pretty silly scene. Mom was still on all fours, her great tits pointing straight down, and Chuck still frozen in her cunt. He looked like a deer in the headlights of an oncoming truck.
Annie stuck her head back in the open doorway. “It was all my fault, Mrs. Lange. Please don’t blame Mike for any of it. He was following my wishes, and let me assure you that I was the one who initiated sex with him.”
Mom stared at us incredulously and then she began to laugh. She laughed so hard her tits were swinging violently, and tears were streaming down her face. She gasped for control and then managed to blurt out, “Here I am, the mother of a teenage boy, with his seventeen-year-old friend’s cock in me, and you are apologizing for having sex with my son. Does anybody think this is funny besides me?” Chuck laughed nervously as Annie looked at me, trying to comprehend the situation. I smiled at her and wrapped an arm around her shoulder as I pulled her to me in the door opening. She smiled at me tentatively and then smiled at Mom uneasily. Mom burst out in a fresh fit of laughter, and her tits jostled wildly. Annie’s eyes were huge as she looked from Mom to me, and her tentative smile began to relax. I hugged her to me as we both looked at Mom and Chuck. Mom finally seemed to get control and gasped out, “It’s OK, Annie. I understand, and believe me, I know how you feel!” Then she burst out in a fresh fit of laughter and looked back at Chuck.
“Chuck, honey, wouldn’t you agree?” She grinned at her, then nodding, finished the stroke into her that had been suspended a few moments ago. Mom’s eyes closed for a moment, and she looked up at us. “You two relax. Get back in bed or something. We’ll talk when Chuck and I finish this. It may be a while. This boy can last forever.” She was laughing again as I reached into Mom’s room and pulled her door shut.
Annie looked at me with wondering eyes and said softly, “Wow!” I led her back to my bed, pulled the covers down, and we got in. I cuddled her to me and told her that Mom and Chuck had been lovers since Annie and I had started. With a note of wonder in her voice, she said softly, “She didn’t seem upset with me, honey.”
I laughed softly, “Nope, she seemed to think it was funny.”
Annie giggled softly, “I think I really like your mother, honey.” I hugged her, and then we had a long kiss. She sighed and whispered that she loved me. We proceeded to make slow, sweet love. She was the sweetest, sexiest, lover a man could have. I gave her all the love I had so that she would be happy with me. It seemed to work, and we fucked each other with the perfect meeting on every stroke. She had two orgasms before I came in her with surges that came from my toes and built to a red cloud over me. She was on top of me, being cuddled when Mom came in. Annie started, but Mom reassured her that it was OK and to stay where we were. Where we were was ... my cock in Annie’s oozing cunt. Mom had the silk nightshirt on, and she sat right on the bed at my shoulder.
Mom started without preamble, “Tell me about you two.”
“I’m in love with her, Mom.”
Annie said sweetly, “And I love him with all my heart, Mrs. Lange.”
Mom laughed, “You have to call me Linda, or I will be upset.”
Softly, I said, “Mom, we want to get married before I graduate from college and have our first baby on the way. Annie wants to get her master’s while I’m in school for my bachelor’s. We plan on getting an apartment off campus next January.”
Mom looked down at me and asked, “Is that why you want to graduate early?” I nodded.
“Mike, you are barely seventeen. What makes you think you are ready for marriage and a family?”
I answered as earnestly as I could, “I’ll be twenty or twenty-one by then, and I’m sure we will know it’s the right thing for us by then. Think of it as a four-year engagement, Mom.”
“Do you both realize what will happen if the school finds out that a teacher is having sex with a student?” We both nodded, and I tried to reassure Mom that we were careful.
“How did Kathy find out?” I told her about the slip I had made and Kathy putting two and two together.
“Well, let’s not make any more slips like we did today, or it will be all over town, and who knows what would happen then?” She said resignedly, “I guess Annie wouldn’t be in as much trouble as I would be if Chuck’s parents found out. Annie, I guess that means that you are now a member of our strange family. We might as well change the sleeping arrangements. Come on, you two, let’s move Chuck to my room, and Annie can move in here.” Annie got off me and scampered into the bathroom. Mom whispered, “Does she know about you and Kathy?” I nodded. She rolled her eyes, “How about you and me?” I shook my head.
“This whole thing just gets stranger and stranger.” She grinned sardonically and gave my sticky cock a flick with her finger.
“That thing has caused a lot of strange events in my life.” She laughed and went back to her room. Annie came out and asked if I wanted a shower. I nodded, and we went in together.
“Your mother seems pretty calm about the whole thing, honey.” I told her how Mom had been celibate since Dad died and had avoided relationships. Then when Chuck and she started up, she suddenly seemed a lot happier and certainly well-fucked.
“Does she know that you and Kathy have sex?”
I paused and nodded.
“She figured it out real quick. You know all too well how loud Kathy gets!”
She laughed and hugged me, asking, “How did she take it?”
“She seemed resigned about it at first. Kathy was her irrepressible self and wouldn’t let Mom try to ignore it. She either had to accept it openly or try to stop it. Need I say that she didn’t try to stop it?”
As she washed my cock slowly with soapy hands, she asked, “How does she feel about Chuck?” Now she was getting onto shaky ground. Carefully, I said, “I think she loves having sex with him, but I don’t think she’s in love with him. Chuck has had a crush on her since we were little, but he doesn’t seem to have gone goofy. It might help Mom if she talked to you about it. I know she worries about her influence on Chuck.” She nodded, and we quickly finished. After drying, she put on one of my shirts, and I put jeans on. We knocked on the door and went into Mom’s room. She still had the silk shirt on, and Chuck was dressed. We quickly moved Annie into my room and Chuck into Mom’s. Mom and Annie discussed what to wear to dinner and scanned the clothes they had brought. They agreed on conservative outfits from Chuck and me. Annie explained that it wouldn’t do to have a teacher at a school-related function showing cleavage, especially if she was with students. She grinned at me and said softly, “How about if I don’t wear panties or pantyhose?”
She looked at Mom, and Mom shrugged as she smiled, “Oh, what the hell? We will be the only ones that know. Right?” Chuck and I nodded. She grinned at Annie and sent us back to our room so she could get ready. I dressed quickly while Annie did her hair and makeup. I noted that my shirt collar was tight, and the sleeves seemed short. I asked Annie if she wanted me to stay with her, and she told me to go. She would meet me in the lobby when she was dressed. I kissed her neck and stuck my head in to see if Chuck wanted to go down with me. Mom said she would come down with Annie, and we went down to the lobby.
The hotel lobby was busy with lots of kids in for the science fair, their parents, teachers, and the regular business crowd. The hotel was old with lots of ornate chairs, couches, and seating areas laid out like formal “rooms” where groups could collect. We sat and watched the hubbub, making comments about the various people we saw walking through the lobby. Most of the teenagers looked like the school nerds. There were some exceptions that included two girls that wore mini-skirts and sweaters the right way. They saw us watching and pretended to be cool, but the nervous giggles gave them away. I felt superior to the normal teenage role-playing and realized that Chuck and I would have been more nervous than the two girls a few months ago. I smiled at them and waved as they looked back at us on their way to the elevators. Chuck noticed and commented that they were acting awfully juvenile. I reminded him that they were our age, and he realized what I had been thinking. I wondered aloud if I was maturer now or if I was just playing an adult role. He noted that we hadn’t talked about any girl’s tits or ass for a couple of months. In fact, we had no conversations about women in general because the mystery was pretty much gone. I laughed and told him that masturbation used to make my brain mushy.
We were talking about the presentation when the ladies came down. They were dressed conservatively, but the sexiness was still there. Mom had a high-neck black sheath, slit on the sides to just above her knees. Annie was wearing a long pleated plaid wool dress with a tan Cashmere sweater and an unbuttoned cardigan over it. She looked like a schoolteacher, except for the makeup, jewelry, hot figure, and flashing eyes. I guess a better description would be a really hot schoolteacher. They were talking to each other and laughing as if they had been friends for years. I couldn’t help but feel a swelling of pride. They spotted us as we stood and walked toward us. I noted that many nerds were staring at them as well as the adults. Even dressed down, they stopped traffic. I offered my arm to Annie, and she took it with a flirty look. The restaurant was off the side of the lobby. Mom and Chuck led. I watched Mom’s ass twitch sexily, and I realized she wasn’t wearing panties. That made my cock twitch a bit. Annie noticed and said under her breath, “She has a great ass, doesn’t she?” I blushed, and she squeezed my arm briefly.
There was a wait for a table, so we went into the bar. No tables in the bar were available, so the ladies sat on bar stools while Chuck and I stood. A crusty little bartender, with white hair, took our order after Cardin Annie. It didn’t seem to bother her, and I realized that it probably happened to her a lot. I had four more years before I could order a drink. Jeez! She saw me looking at her and smiled as she fingered the pendant. Mom noticed the pendant and said, “That’s an unusual necklace.”
Annie’s eyes sparkled as she said, “It was from Mike.” Mom looked at it closely and recognized the coffee bean.
“I take it that there is some significance to the coffee bean?” Annie giggled and nodded. Mom looked at me with a raised eyebrow. I nodded, and she said, “I take it that I will have to be told that story when we aren’t in public?” Annie gave a sparkling smile and nodded.
Looking at me with a sexy smile and fingering the pendant, Annie said softly, “I’ll order room service coffee for breakfast tomorrow.” My cocked head lurched.
Mom laughed and asked Annie in a whisper, “Is this coffee an aphrodisiac?”
Annie’s eyes lit up. She nodded and said to Mom, “I’ll order two pots in the morning.”
Grinning at her, Mom said, “I can’t wait to find out.”
“It will rapidly become your favorite kind of coffee.” Annie’s eyes were dancing with mirth.
We were called to our table and led into the restaurant. It was dimly lit, and the predominant light source seemed to be the candles on the tables. It was an elegant setting. The tables were set with pressed white linens, crystal, and silver. The waitress was an attractive young woman in a black skirt and tuxedo jacket. Mom ordered a bottle of Dom Perignon and four glasses. The waitress didn’t blink. I looked at the wine list after Mom put it down, and it was a very expensive wine. I guess she figured this was a special occasion. We looked over the menus. When the wine arrived, Mom ordered several appetizers, including oysters. After the waitress poured and left, Mom raised her wineglass to Annie and said softly, “To my future daughter-in-law.” I just about cried as I toasted Annie with Chuck and Mom. Annie’s eyes were sparkling and moist as she thanked Mom. Mom looked at Chuck and me as she said, “You boys had better eat all the oysters. You’ll need them this weekend.”
I raised my glass to Mom and Annie as I said quietly, “May this hotel have enough oysters for this weekend.” We all laughed and drank. When the oysters arrived, Chuck and I did our duty and ate most of them. We also finished the champagne, and Mom ordered another bottle. The waitress was very nice and made several recommendations for dinner that we all took. I had always wondered what a filet of sole was like, and the waitress assured me that it was prepared “almondine” and I would love it. Annie ordered veal, Mom had lamb, and Chuck wanted steak.
We had finished our salads when an older woman in a gray wool suit greeted Annie. Annie stood and hugged her, then introduced her as her student teaching mentor when Annie was in college. They exchanged information about so-and-so and agreed to talk at the auditorium tomorrow. After the lady left, Annie said softly, “I’m very glad I dressed like this. If that old biddy had been suspicious, the rumors would have been all over the state tomorrow. She is an incredible gossip.” She looked at me with a level stare and warned, “If she asks you anything, act like a dimwit.” I grinned and told her that wouldn’t be hard.
The dinner was delicious, but I was very impressed when the waitress removed the bones from my fish with a couple of spoons and a little flourish that landed the bones on a side plate as a unit. We had no trouble finishing the second bottle, and I was very light-headed when we went up to our rooms.
I had Annie’s clothes off in seconds. We held each other close, and I told her how wonderful it was to be open with Mom about our love. She agreed, and we had a long series of passionate kisses. I explored her body with kisses and tiny little sucks. She was free in her movements and more expansive in her expression. I asked if she was drunk, and she giggled. I noted that my mouth and nose couldn’t smell and taste as sharply. I was kissing her thighs when she grabbed my ears and pulled my face tight to her pussy.
“Kiss my clitoris, honey. Don’t tease me.” I took the hint; I was afraid she would pull my ears off! I pushed a finger into her cunt to rub her sensitive spot and sucked her clit gently. She was having an orgasm a few minutes later, while still holding me by my ears. She pulled me up to her face and told me, “Fuck me.” I pushed my cock into her, and we had a hard, fast fuck. She was intense and directed the speed as we met each other at the midpoint of the thrusts. She was cumming hard when I exploded in her and tried to drive my cock through her. We collapsed, and I lay on her for a few minutes as we recovered. She giggled and said softly, “I’m drunk, honey. Could you tell?” I laughed and told her we both were. I got out of bed and fetched her some water after I had a long drink. We placed an order for room service for breakfast at 7:00, two carafes of coffee, and four cups. Annie giggled, “Your mother is going to love coffee.” We fell asleep cuddled together. I woke during the night with a headache and needing to piss. I took three aspirin, pissed, and snuggled up with Annie.
