Ending 4: Open Relationship

Swinging Round And Round

You try your best to hold back your orgasm as she clenches hard on your cock. Her pussy is extremely tight and you rock gently, scared of hurting her with your girth. You cup her small breasts, enjoying the feeling of enveloping them completely in your hands as her hard nipples poke delectably into your palms. You watch in appreciation as, across the room, Karen’s lover picks Karen up as he continues to fuck her pussy while standing. She wraps her legs around his waist as he holds her aloft with his hands firmly gripping her ass. She gives a guttural scream of pleasure every time he lifts her up and releases her, letting gravity make her slide roughly back down his long cock until he bottoms out. You genuinely enjoy the view: getting fucked this way was one of Karen’s favorite fantasies, but you just didn’t have the upper body strength to fulfill her desire. Luckily, Sean had no problem filling the void, his youthful body able to hold her up for as long as she wanted.

Your attention returns to Megan who lies below you, panting and moaning with her eyes closed. She squirms with pleasure while your pace builds up steadily, as she wills her pussy to open up more for you. She had cum twice already, the first time on penetration alone, and your crotch was damp and musky with the juices she had squirted out.

“Baby, I’m so close,” you hear Sean call out. “Can I?”

“Not yet!” Megan snaps back immediately. She gives him a warning stare and Sean moans in frustration. You hear Karen cum loudly, her third in quick succession, and she shakily gets off Sean and heads to the two of you. She lies down next to Megan and the girls kiss and play with each other’s breasts. Sean obediently stands at the edge of the bed, his erect cock twitching and dripping precum, as he watches you pleasure his girlfriend. Karen uses her feet to tease his swollen prick, her toes dancing naughtily along his slick shaft, the underside of his balls and along the cock ring keeping his dick clamped shut. Sean’s legs tremble visible as he struggles to stay upright - his brain caught in the **** of Karen’s attention and his inability to cum.

Megan grins evilly at him as she commands, “If she makes you cum, it’s the cage for the whole week. No exceptions! You know that I don’t need your cock anymore now that I can fuck Mark whenever I want.” Sean swallows hard and nods in agreement, his torment unable to make him speak. She then turns to Karen and, making sure Sean can hear her clearly, tells her, “If you make him cum with your feet, I’ll be your **** for the rest of the day.”

Karen gets to her task with alacrity, expertly using her beautifully manicured toes and soft soles to stroke and pleasure his cock. Sean starts to beg for mercy but his pleas fall on deaf ears. You start fucking faster, knowing how turned on Megan is from the view. Finally, he can’t take it anymore and turns to Megan. “Babe, pleeeease!” he moans loudly. “Please, please give me permission.”

“You know the consequences right?” she teases him

“I don’t care! Please, please. Fuck anyone you want. Cage me as much as you like. But please, I’m so close!”

Megan nods at Karen who unhooks the clamp keeping the cock ring shut. Karen then kneels with her mouth wide open, ready to receive Sean’s load. You feel Megan’s pussy throb and grip you as the girl edges closer to her own orgasm. “Cum for me baby,” she pants finally. “Show Karen how much you love me!”

Sean unloads with a loud moan of satisfaction as he pumps load after load into Karen’s mouth and face. You hear Megan cum below you as she squirts again, weakly grabbing your hands for support. As always, you were amazed at the length of Sean’s orgasm and the size of his load. You would have never believed that men could orgasm for that long if you hadn’t seen it with your own eyes.

Once he was done, Sean collapses on the floor, unable to move or talk except for a string of panting grunts. Megan slides you out and crawls over to where he is and cradles his head onto her chest, whispering gently into his ear as she uses her hands to stroke his body and calm him down. Her dom mode has completely disappeared and is replaced with her true nature – a sweet and caring girlfriend who is very much in love with her man.

Karen moves up to you, Sean’s cum dripping from her face, and lies down as she offers her pussy to your unsatisfied cock. You readily accept, turning your eyes away from the couple on the floor, not wishing to eavesdrop on such an intimate moment. You slide inside Karen and your cock throbs as you see your wife’s face light up with pleasure at your entry. A sudden metallic click distracts your attention back to Megan. She’s placed a chastity cage on Sean’s cock, just like she had warned him earlier. Well, mostly sweet and caring, you tell yourself as you go back to making love to your wife.

The two of you started to introduce other lovers to your bed since that holiday with Sarah and Jakob. During the first two weeks of opening up, you two barely fucked each other: satiating your lusts by spending nights with a variety of different lovers. Each night you had been delirious with the combination of the excitement of fucking a new lover, the thrill of being able to openly cheat on your girlfriend, and the happiness at knowing that Karen was also enjoying herself at her fuckbuddy’s house.

After the novelty of sleeping around had diminished, the two of you began to spend nights together again: lovingly fucking and pleasuring each other as you both swapped stories of your sexual escapades. The two of you settled into a less adventurous rhythm, inviting lovers and other couples over only during weekends.

It was no surprise that she quickly took Robert as her lover. It had not taken much to convince your best friend to sleep with her - you had invited him over one night for dinner. After he was a few drinks down, Karen walked into the room dressed in nothing but sheer lingerie. As he stared open-mouthed at her, at a complete loss for words, you had whispered into his ear, “Three rules: treat her with respect, NO condoms, cum inside her pussy. Also this is the only night I’m not joining in, so make full use of it.” You then made your way to the guest room, grinning with happiness at finally being able to fulfill Karen’s fantasy, as you left the two of them alone.

Your sleep was interrupted many times that night, as the two lovers screamed and moaned with pleasure through the thin walls.

A few days after that, Kate had called you aside at work. “Karen invited me to dinner yesterday,” she told you, her gaze not quite meeting your eyes as she bit her lower lip. You were surprised: you knew Karen had dinner outside last night, but assumed it was a date with a new lover.

“She told me that you two were in an open relationship?” she questions.

“Yes, that’s true,” you answer, wondering what Karen had set you up for.

“She also said that you wanted to fuck me. She... she told me that she’d be really happy if I wanted to fuck you too.” Kate’s face is flushed now, her breathing irregular. You notice that her nipples have hardened under the thin fabric of her shirt.

“What did you tell her?” you ask as you move closer to her.

“I admitted that I had a crush on you for the longest time,” she replies, her voice practically a whisper, “but I gave up after I saw how happy you were with her. But I didn’t lie, I told her I wanted to fuck you too.”

You kiss her mouth and she replies with enthusiasm, her hands flitting lightly over your hardening crotch. You gently pinch a nipple and she breaks off gasping, with a moan. “Not here!” she admonishes you. “Somebody could walk in at any time.”

“Nobody comes here at this time,” you reply. “Besides, it’s hotter if we risk getting caught. Don’t act like it doesn’t turn you on: I’ve seen the way you dress. You have an exhibitionist streak in you.” You slide a hand inside her skirt and start massaging her wet pussy.

“Oh God! I can’t believe I’m letting you do this,” Kate whispers but spreads her thighs apart for your hand. Her fingers quickly unzip your pants and pull out your mostly erect cock. “Oh fuck!” she gasps in pleasant surprise. “It’s so big! It’s so much better than I imagined.”

You had wanted your first time with Kate to be slow and comfortable, where you could take your time worshiping her sexy legs. Unfortunately, the cramped room and the risk of discovery made it a quick and uncomfortable fuck. Kate enjoyed it though, biting hard into your shoulder to stop her moans as she came. She then let you cum inside her mouth, since neither of you had a condom on hand. “Can you sleep at my place tonight?” she asked after she swallowed your load, licking her lips with pleasure at your taste. You immediately nodded in assent.

As both of you rearranged your clothes and tried to look presentable, you were hit by a sudden thought. “Karen came home pretty late last night,” you tell her. “And how the hell did she manage to convince you to confess your crush on me?”

Kate blushes a sudden, deep red; her face was so inflamed that for a moment you thought that she had fallen ill. Refusing to meet your eyes, she takes a deep breath and mumbles, “Mark, Karen’s a lovely person, and I’m genuinely happy you found her... but she scares me a little. I... I think she might not really be human.”

“What?” you ask confused. “What did she do to you?”

“Well we met and chatted for a few minutes. It was a little awkward at first... talking to the girlfriend of the guy you had a crush on. But she was very sweet and fun to talk to. I was really enjoying chatting with her.” Kate turns around, refusing to even face your general direction out of embarrassment. “Then she started flirting with me. And... and I enjoyed it. Like... I’ve never been interested in girls, and I knew I should stop her... but I couldn’t. I wanted her to go on.” You see her hands move to cover her face. “I don’t know what she did to me! After teasing me for like half an hour, she just said, “I want to eat your pussy. Come to the bathroom with me.”” Kate falls silent for a long time, before she adds in a very tiny whisper, “And I did.”

It takes a lot of effort for you to **** back your laughter. A part of you is extremely amused at Kate’s sexual awakening, another part equally amazed at how quickly Karen managed to seduce her.

“I actually let a girl eat me out,” Kate continues, “and it was amazing. She made me scream... I... I can’t go back to that restaurant. Everybody knew what we had done when we left the bathroom. They were all staring at us, even the waiter, as we paid the bill. It was mortifying,” and in a much lower voice, “and so fucking hot!” A pause, and then she says, "Anyway, after all that, she told me you two had an open relationship and wanted us to be lovers if I was interested."

As time passed, Kate overcame her inhibitions quickly enough to join you and Karen in your lovemaking. With Kate’s permission, you started inviting Robert when she was over and the four of you spent many pleasant weekends in each other’s arms. A few months later, the two of them started hanging out together and began visiting your apartment less. A little while after that, they told both of you that they started dating and wanted to be exclusive to each other.

Karen and you had seen the signs for a while and were genuinely happy for them, albeit a bit disappointed at the loss of such fun lovers. “This is just like Sarah and Jakob,” you had told her excitedly. “I think you have Cupid’s touch, love.”

“At least Sarah and Jakob continued to fuck me when they were dating,” Karen had replied morosely, taking the loss of Robert’s cock a little harder than she expected.
