The following week was a whirl as we got back into our routine. I had a hard time concentrating on my studies as I daydreamed about the vacation. Everyone commented about how tan Kathy, Chuck, and I were. They didn’t seem to make any connection with Annie’s tan. Billy was very flirty as I struggled through my workouts. Mom made arrangements for Kathy’s birthday party, the weekend after next. I had a hard time realizing she would be sixteen. Annie had a hard time realizing that she was only sixteen. Kathy was torn about whom to invite, so I stayed out of it as much as possible. I just went shopping for cookbooks, a chef’s hat, and a jacket. The latter two items were easy to find at a restaurant equipment distributor in town. Annie had more homework each night than we did, and she rarely came to bed before eleven.
The e-mails continued from Lila, but now they were encrypted. She was graphic in her descriptions about how she was going to fuck me when she came for her visit. Need I say that Annie and Kathy received a few of the hard-ons Lila caused? She had told her “mama” that she wanted to start taking birth control pills, and that had caused an eruption for a couple of days as her mother tried to find out who she was having sex with. Lila assured her that it was just precautionary since she was going out with a boy from her school. Her mother finally relented, but she was never to let her “daddy” know. Lila said the boy from school was never going to even touch her breasts. She was sure that he would blab it to all his friends, so she was resigned to remaining celibate until her visit. I showed them to Annie and Kathy. They started writing her too.
We had a call from Anita, Friday night, to tell us that she had a court date set already. James had an attorney, but they had run over him in the first meeting, and James had agreed to all the terms. She expected the divorce to be final within two months, probably a record in Connecticut. She said James looked like hell during the meeting. His face was an ugly green and purple on one side, and his black eye was still puffy. He moved like an old lady, and every time he sat, he groaned. His lawyer had started to make a scene about contesting the conditions until the pictures of James and the banker were shown, the affidavit from the ship’s doctor, and the picture of Anita’s bruised face. When Anita’s lawyer had broached the subject of a restraining order, James had broken down and started crying. His lawyer had quickly ushered him out of the room, and when they came back in, the fight was out of the James’ lawyer. She said she missed us all and especially her wonderful lover boys. She giggled and said she was getting very horny. Kathy had to rub it in and say she wasn’t horny at all. Anita growled that she was going to have to go upstairs and masturbate after we hung up. Kathy invited her to the birthday party next Saturday. Anita said that she just might come to it, just so Kathy couldn’t go to bed with either Chuck or me. Anita would take us both to a hotel for the weekend as her private studs. They sparred like that for a couple of minutes, and it ended when Kathy capitulated and said she would share. She gave her love to all of us when she hung up.
The big surprise, Friday night, was that Chuck’s parents made him go to his aunt and uncle’s. Steph was pretty upset about it, and I had to relay to Chuck that she would be waiting for him Saturday morning. Steph kept him in bed all day Saturday and most of Sunday.
Kathy and Mom had their periods the following week, so Annie and I had each other for five days. Kathy grumbled the whole week. Wednesday, after school, Annie and I bought her a coffee bean pendant for her birthday present from both of us. Chuck went with us and bought her a sexy red silk shirt. Annie bought her matching red silk panties and bra. I commented that the bra was like not wearing a bra. Annie grinned and repeated a now familiar phrase, “That’s the idea, honey.”
Friday, after school, there was a message from Mom to call her at the office. I called, and she told me to be at the airport at 5:30 to pick up Anita and not to say anything to Kathy. I was to take Anita to the house at 6:15, so Mom could be home when we arrived. I told Annie when she got home. She was excited to see Anita and thought it was very considerate for her to come. I left for the airport, telling Kathy I had to pick up her birthday cake. Anita’s flight was a half-hour late. She came off the ramp, looking like a New York society lady, which she probably was. She had a full-length fur coat on, that I learned later was sable. It was certainly soft. She wasn’t a society lady when she kissed me. Her tongue painted my tonsils, and her body pressed against me hard. Man, she was horny! When the kiss ended, she whispered, “My God, honey, you look good enough to eat. If I didn’t want to fuck you so badly, I would eat you up!” She held my arm as we waited for her bags. She looked cool and aloof as we stood there waiting, and she drew lots of looks from men and women. She was obviously not a local resident. She didn’t travel light. We put her two big bags and shoulder bag in the car. As we headed home, she snuggled up to me and cupped her hand over my rapidly swelling cock. She nuzzled my neck and whispered at the first stoplight, “When we get to your house, I’m going to put your cock in my pussy. I may not even say hello.” At the next light, she whispered, “I think I’ll suck your cock before we get there. You fuck so much longer after you have an orgasm.” The next, “I think I’ll fuck you till you have your first orgasm, and then I’ll fuck you until the second.” All the while, her hand gently squeezed my cock, and her lips brushed my neck.
I decided to retaliate, “Anita, I’m not going to fuck you. I’m going to kiss and suck your nipples till they burst from the swelling.”
She sighed, “Well, my dear, my poor nipples will look forward to that experience.” I laughed and hugged her.
“God, Mike, I’ve missed you. I literally lay in bed at night wondering if what I experienced was my imagination, working overtime, or if I was going batty from an overactive libido. You know, darling, that you have made me into a sex maniac.” I kissed her warmly at the next light, and a car full of kids honked at us. Anita broke the kiss and smiled at them sexily. I thought I recognized one of the girls. I was aching hard when we got home. I carried in her bags as she made a grand entrance. Kathy squealed and rushed her for a kiss. Mom and Annie were next.
Anita asked if Chuck was coming, and Kathy laughed; “He might be. He’s upstairs in bed with Aunt Steph. She is a nympho when it comes to Chuck.”
Anita snorted, “I can certainly understand how that could happen.” Mom had taken her coat and was stroking the fur. She commented on the lovely coat. Anita gave a scornful look; “Little dick got it for our anniversary. I’ll probably end up paying for it if it’s on a joint account. The closing statements haven’t arrived yet.” I was still holding her bags and asked where they should go.
Mom looked at her with a questioning eye; “Mike’s room or mine?”
Anita smiled; “What a choice.” She looked at me with a raised eyebrow. I nodded and started for my room. Anita said with a little laugh, “Maybe I should see where it is.”
Mom smiled and nodded, saying, “I’m sure you should.” As I went up the stairs, Anita was behind me and whispered, “Hurry, honey. I’m aching.” I laughed and raced for the room.
She giggled and followed, as Kathy’s voice followed, “What’s the hurry, Anita?”
Anita yelled over her shoulder, “It’s been two lonely weeks!”
In my room, she turned her back to me and asked, “Do my dress, honey?” I found a button at her neck and then the zipper down to the crack of her ass. She had the entire suit of body armor on: slip, bra, panty hose, and panties. It all came off, along with her jewelry. I was naked while she was still taking her panty hose off. It was a struggle, and I told her making love to her on the cruise was a lot simpler. She nodded as she worked, and I tried to help. When she was naked, I commented that she looked a lot younger with her clothes off. She giggled as she grasped my cock and told me I looked a lot older. I laughed, picked her up, carried her to the bed, and we fell onto it in a kiss. I took my time on her neck and her breasts. She finally pushed me down off them. I moved to her belly and then down her thighs to her knees. Her pussy hair was freshly trimmed, and her labia were glistening. I slowly worked up the inside of her thighs, and she rolled her hips. “Mike, honey, you make me ache like no man ever has. God, I love this!” I pushed her knees further apart and began working a wide circle around her pussy. It was a few minutes, and she was trying to move her pussy to my lips. I avoided it until she grabbed my hair and pulled my face against it. It was either that or go prematurely bald. Her labia had been recently shaved or waxed, and the coating on them, with her juice, made my lips slide over them as I sucked and moved. She smelled of woman’s pussy and an expensive perfume. My mouth watered, and my senses filled with her sexuality. I vowed to make this one memorable. I smeared her juice over my face as I sucked lightly and tasted her pussy with the tip of my tongue. I reached up to her tits, stroking them as I moved my lips over her pussy. She was murmuring in appreciation, and her hands moved over my head gently. I moved my hands down over her waist and hips, then down her thighs to her knees, and lastly to her feet. I ran my thumbs over her arches and got a reaction. Her feet must have been ticklish, so I experimented by lightly dragging my fingernails over the arches of her feet. She jerked her feet away suddenly and gasped, but her pussy jerked against my lips. I grabbed her knees and then ran my hands to her feet again. This time when I tickled her feet, I pushed my tongue into her cunt. She shrieked and her heels slammed into my butt as she arched hard. I tickled her feet twice more, with my tongue buried in her cunt. She had a hard orgasm, holding my face to her pussy and squeezing me with her thighs. I felt like a king, making her cum without touching her clitoris. She released her clamps on my head after her orgasm died and I went to my more traditional methods, rubbing the sensitive spot in her cunt as I sucked her clit. She had another hard one and her belly was fluttering this time. Before she eased up all the way, I pulled away and guided my cock to her cunt. She had tightened up in the two weeks and I had to go gently to get into her. She was encouraging me and her heels pressed against the back of my thighs. She was moaning and telling me, “Push it in honey. Oh shit! God, I had forgotten how much you stretch me.” I waited until she urged me to push again with her hands. She seemed tighter than I remembered. I was patient and talked to her as I waited. I was feeling big and hard when my cock suddenly slipped completely into her cunt. It was so good! She gasped and held me tight with her arms and legs. I nuzzled her neck and whispered how good it was. She was panting when she gasped, “Oh God Mike, this is so good! Fuck me honey. I need to feel you filling me.” I began to slowly fuck her and she began mumbling nonsense. I figured she was having little orgasms because her nails were digging into my butt. A long while later, I was fucking her hard enough to get the first surge of cum. She was almost delirious by then and her coif was shot, strands of hair stuck to her sweaty face. She was in constant orgasm when I yelled and began pounding her hard. The cum shot into her, and the cloud swallowed me.
Later, I rolled us over, and we talked. I asked her about the tickling, and she said that when she was going through puberty, a playmate girlfriend used to tickle her until she had an orgasm. I asked her if she still could, and she murmured, “Maybe.” I told her we would save it for later. She sighed and wiggled her cunt on my cock. She softly asked me to give her the phone. I reached over and set it beside us. She raised up on an elbow and dialed. When the other end answered, she asked, “Could I speak to your mother, Amy? It’s Anita.” There was a pause.
“Greta, honey, guess where I am?” She giggled, “I’m lying on top of Mike with his great cock in me and his semen dripping out of me.” There were several confirmations, and then she grinned at me, “Greta is jealous and wants to be here too.”
I called out, “We miss you, Greta.” They talked a few more minutes, and she hung up.
“I couldn’t resist that. We talk almost every day, and sex is always one of the items for discussion. Poor Greta is even worse off than I am. She doesn’t masturbate at all.”
We were still snuggling and talking when Kathy came in. “All right, Anita, get off his cock. We have dinner reservations in an hour.” Anita complained that she wanted more sperm for dinner. Kathy slapped her butt and laughed, “Pretty horny are we?” Anita affirmed that she was sated for a little while and would let me up, only so I could get sustenance for the next round. We kissed lightly, and she got off me. We were pretty sticky, so I led her into the shower. We cleaned up after I ate her to another orgasm in the shower. She was giggly and talking like a little girl as she put her makeup on and fixed her hair. I dressed for dinner as Annie and Kathy came in to get ready. I went downstairs to wait for everyone.
Anita met Steph when they came down from Mom’s room. Anita was dressed like she stepped off the pages of Vogue magazine. I’m sure it was a designer dress, and she had her big diamonds on. Steph immediately liked her, and they discussed Anita’s dress, a long sheath that was black with a sheer patterned skirt over it. There wasn’t much cleavage, but it clung to her breasts nicely. It was a designer that all the women knew of, and Anita said she would take them to the studio when we came to New York. Well, that was the topic all the way to Karen Schmidt’s restaurant, after we all crammed into Mom’s big Suburban.
Dinner was wonderful, as always, and Anita brought us up to date on events with her and Greta. Greta believed her husband was being investigated by the police for pedophilia and sodomy. Calls from scout parents had suddenly stopped, and her lawyer refused to talk about it until something was known. Greta was filing for divorce, and the bank had put her husband on a leave of absence. The daughter was still upset about losing her father, and Greta was having some trouble getting money out of her husband. The bank board had sent a vice president to her, asking that she keep the whole mess as low-profile as possible. They had come to an agreement that she would have access to half of the accounts her husband held, and he would not be able to close them. Her biggest worry was losing everything to legal fees if her husband was charged. Her lawyer was working to get the divorce and property settlement completed before any criminal charges were pressed. We all agreed that Greta would need all of the help she could get.
Anita said that she had held two more meetings with James and his attorney. He had been utterly mute during both meetings, obviously under orders from his attorney. She expected the divorce would be final in another month.
The conversation turned to the weekend agenda, and I brought up the subject of going to the cabin after Kathy’s party. Mom thought it was too much trouble for just a day, but Kathy, Steph, and Annie voted to go. Anita was especially interested when she found out clothes were optional.
The trip home was interesting when Anita and Steph started giving Chuck a blowjob. There was no delay in getting him up to Mom’s room after we arrived. Mom was sighing as they went upstairs in a rush. Kathy hugged Mom, “Why don’t you come to bed with us, Mom? They will be up all night, and I’m sure you are horny.” Annie joined her in the hug, and it was decided.
Mom, Annie, Kathy, and I went up to my room. They were giggling as we undressed, and Mom wondered how the four of us would get any sleep in one bed. I wondered too. How was I going to satisfy three women? Fortunately, my earlier bout with Anita had taken the edge off. By prolonged oral sex with each of them, Annie helping with breast stimulation, and keeping Kathy’s mouth off my cock, I managed to fuck all three to orgasm before I came in Annie. I fell asleep, exhausted, with Annie on top of me.
I woke, having to piss, and found Annie and Kathy gone. Mom was snuggled against me. I quietly got out of bed, pissed, washed dried cum off me, then looked in Kathy’s room to see them both asleep. I smiled at the thought and got back in bed with Mom. She woke and murmured, “Good morning, honey,” as I cupped her breasts from behind her and nuzzled her neck. I stroked her breasts for a long time, with one hand, and let the other roam from her tits to her knees, paying particular attention to lightly tracing her labia and stretching the hood over her clitoris gently. She slowly got turned on. The indication was pushing her ass back against my cock, pointing down, nestled in the crack of her ass. I began pushing against her ass as I played with her body, and after a while, she lifted her leg so my cock could fit along her pussy. I scooted down a bit so it would reach up to her pubic mound. She lowered the leg to squeeze my cock between her thighs and began a gentle rocking motion, which quickly lubricated both of us. Her smooth labia got very slippery, and I could feel them part more as she rocked, working me deeper into her slit. Her clitoris was rubbing over the knob of my cock, and it felt like a slippery, hard pencil as she went faster and harder. Her breathing became strained, and she clutched my hands to her breasts as her pelvis worked frantically. I let her dictate the pace and quit pushing as she neared her climax. She was sobbing when she gave repeated hard jerks of her pelvis for a minute, and then she quieted. I waited for her to begin again, and a few minutes later, as I continued to caress her breasts, she began the slow pelvic thrusts. Her pussy was really slippery now, and I was getting the urge to enter her cunt. She felt my movements and began rocking further, bringing the tip down to the entrance to her cunt. Several minutes later, she lifted her thigh, and with a longer rock, I slid into her cunt. I moaned and thrust deeply into the slippery, hot home of my cock. She held still as I kissed her neck and shoulder, whispering how much I loved her. She whispered her love as she reached a hand behind me to hold my butt tight. I let my hand play down over her belly to her clitoris and then to her parted labia around my cock. I did it very gently. When I was at her clitoris, I used the pads of my fingertips to very lightly play over the sensitive nubbin. I worked as she began moaning and fucking me. I continued to play her clit as she fucked me, holding my thrusts back. A few minutes later, she had another orgasm. Once again, I held still and waited for her to resume. This time, when she started up, she whispered, “Fuck me, honey.” I began meeting her thrusts, still keeping my fingertips on her clitoris. We built slowly, and this time I didn’t hold back. I let my fingertips tap against her clitoris as we fucked hard. The cum surge started slowly, and I warned her that it was starting. She went into overdrive, sobbing and calling for me to give it to her. When I started to come, it was very hard and very long. I was yelling, and then the cloud settled over me. When I regained my senses, she was clutched in my arms, my right hand pressed to her sticky pussy, my fingers fanned with my cock between them. I kissed her sweaty neck and realized we were sort of glued together with sweat. I asked her if she wanted to get up yet, and she wanted to stay like we were for a while. I cuddled her from the back, stroking her breasts and pussy for a long time. I dozed off to sleep like that. I woke a little later, still holding her and my limp cock still in her cunt. I gave my cock a little twitch, and it responded. Over the next several minutes, I concentrated on twitching my cock, and slowly it grew. She was lying quietly, like she was asleep, until I was almost completely hard. When she stirred, it was to whisper, “Now, this is a pleasant way to wake up.” I gave my cock a strong twitch, and she responded by wiggling her ass against me. Suddenly, she pulled away from me and turned over to face me.
“Hi honey, give me a kiss.” It was one of her soft, sucking kisses that made me immediately rock hard. I pulled her against me so I could push my cock against her pussy and belly. She said softly, “Put it in me, honey. I need to feel it inside.” She pulled me on top and spread her legs. Without either of us touching it, my cock found its way into her slippery cunt. She gasped and held me still in her for a minute or so, then we began fucking slowly. She talked to me for several minutes about how good it felt and how much she wanted to fuck me. The speed built rapidly, and I was pounding into her sloshing cunt with all my power as she went crazy under me. This time, there were no stops after she had an orgasm; we just kept fucking harder. It took me a long time to cum, and she was almost hysterical when I finally shot weakly into her. She held me and cooed for a long time until I was able to rise up and begin kissing her face. Some time later, I pulled out of her, and we showered leisurely. She put on one of my sweatshirts and nothing else, then we went down to fix breakfast.
It was an hour later that Annie came down. She grinned when she saw Mom with the fresh, fucked look. She kissed me and asked, “So, did you two sleep well?”
Mom laughed lightly. “It was the waking up that went well.” Annie looked at me and winked. Eventually, everyone came down for breakfast. Anita and Steph had the look too.
Chuck was a little wobbly, and Kathy asked, “Tell me, Chuck, did they wear you out?” He grinned and nodded as he looked at them.
Anita smiled at him lovingly. “It was mutual, Kathy. He is truly amazing.”
