No

As Alyssa's mouth is hanging just a mere inch away from your aching balls, desperate for release, you think about what she just said. She's asking permission from you for Sid to fuck her anytime he wants. You can't stand the thought of what happened in the bedroom just now happening again. Alyssa's body should be yours to enjoy....not Sid's...

You: "n...no..." you say as Alyssa had nearly put her mouth on your balls, clearly expecting you to say yes. She pauses in a confused look.

Alyssa: "What?"

You: "I don't want Sid to fuck you ever again.....It's not right...."

Alyssa sits back on her heels and looks to Sid: "I told you he doesn't want this...."

Sid: "Damn shame....we could have had some great fun...."

Alyssa: "What should we do now?"

Sid: "Nothing's changed, really. We'll keep doing the lessons, but without sex. I have loads more to show you." he says, clearly disappointed with your answer, but doesn't seem to be concerned.

You: "Can....can we take the cage off, then?"

Sid: "You just deprived Alyssa of sex, I think it's fair you also don't get any sex until marriage."

Alyssa: "That sounds fair...."

You: "Then...I want to sleep in my bed...with Alyssa...."

Sid and Alyssa look at each other, and Alyssa shrugs: "I guess since you're caged, that's okay...."

Sid: "...fine....but you're being a real spoilsport, Matt."

You: "I should be the one enjoying Alyssa's body, not you."

Alyssa seems happy with your answer, standing up a little to Sid. She stands up, clearly not going to give you a release, and goes to the sofa. "Let's watch a movie then." so you get up and join Alyssa, cuddling her naked on the sofa while Sid sits on the lounger.

After a while of watching the movie, Sid speaks up: "I'm hungry....mind ordering some food?"

You: "Sure...." You go and get your phone and order some delivery. When you get back, Sid has joined Alyssa on the sofa, leaving no space for you.

Sid: "She seemed lonely...." he says as he massages her breast idly.

You: "I'm here now....get up...." Alyssa looks at you expectantly, almost giving you the signal that she is looking for you to become more dominant, more assertive.

Sid: "Just sit down in the chair...."

You: "No. She's my fiancée, get up." you say, spurred on by Alyssa's look. She clearly likes it. Finally, Sid gets up and you take his place next to your naked fiancée. That felt really good.

In about 30 minutes, the delivery driver shows up, and you ask Sid to use the money you gave him to pay for it. He goes and gets it, then answers the door, fully nude, his cock swinging in the air between his legs. The delivery driver let's out a nervous laugh when Sid opens the door.

Sid: "Hope you don't mind, we're trying to open up sexually here....Tony...." he says, reading the drivers nameplate.

Tony: "haha....whatever dude, that'll be $59.99."

Sid: "Come in, while I count the cash...."

Tony: "Not gonna join a bunch of naked dudes....I don't swing that way.....just give me the cash...."

Sid hands him some money and closes the door behind the driver, and you finish the movie.

Sid: "It's a damn shame you're still so sexually repressed, Matt. We could have had some great fun with this driver, he looked like Alyssa's type....and she needs some experience with more men..."

You: "I think she's had enough experience....she's mine, Sid."

Alyssa: "I like this assertiveness from you, babe. Maybe Sid's lessons are really having an effect on you..."

Sid: "Whatever..." he says, taking a bit of the food.

After you finish the movie, you get ready for bed, moving Sid's stuff to the guest room, and your stuff back to the master bedroom, where just hours before, Sid fucked his cum into both of Alyssa's holes. Trying not to think about it, you cuddle up to Alyssa, your cage pressing up against her pubic bone, causing you to get an erection, which the cage of course stops.

You: "ow...the cage..."

Alyssa: "That's alright, baby, I'll spoon you from the other side." so you turn around, and Alyssa presses her naked breasts to your back, and wraps her hand around your stomach, cuddling you.

Your dick doesn't calm down until you finally fall asleep in Alyssa's embrace. Finally, some semblance of normality.

The next week, you keep going to school, while Alyssa and Sid stay home and continue the lessons. Alyssa said she was fed up with school anyway, and would like to learn how to become a good housewife for you when you get married. She's taken up learning to knit, sow, clean, and cook, and looking up how to take care of babies. Which would be really wholesome if she wasn´t also learning how to accept the pleasures given to her by another man. Sid explained this by saying that a big part of being a housewife is knowing how to please your man. To that end, Alyssa has resumed sucking Sid off at least once every day, while Sid has taken up massaging her sexy body with the massage table you bought for them. Sid said that it is necessary to make Alyssa cum as well at least once a day, so he usually fingers her pussy to completion on the massage table, sometimes with the butt plug inside her asshole or some anal beads. It still bothers you that they're being so sexual towards one another, but at least they're not having sex anymore. It feels like you got control of the situation.

After about two weeks, you're sat in the classroom taking notes from the professor's lecture, when your phone dings. You pull up the phone, and can see from the notifications that it's a photo from Alyssa. But before you can open it, the professor spots your phone and confiscates it.

Professor: "No phones in the classroom, you all know this. You'll get it back after the lecture...." he says as he shuts the phone off.

A bit disappointed, you have no option but to comply, so you keep taking notes and finish the lecture. It takes about 45 more minutes, so when you finally leave, you turn your phone back on. It's a bunch more messages from Alyssa. The first message is a picture, from Sid´s point of view, sitting on the sex sofa you bought them. Alyssa is sat on top of his hips, but you can´t see Sid´s cock....

"Hey bud, It´s Sid. We were practicing positions on the sofa you bought, and we had a bit of an accident. The sofa is angled in such a way that my cock just slid inside of Alyssa´s pussy, probably because of the oil. I just finished massaging her, but couldn´t bring her to orgasm, so we started grinding."

You scroll down to see another picture. This time Alyssa has pulled her hips up and back, giving you a clear view of Sid's meaty, veiny cock lodged deep inside Alyssa's juicy, shaven pussy, stretched to the max to accommodate him. What remains of Sid's cock is covered in her slick juices.

"Alyssa felt bad, so she tried getting up, but she was so oily she slipped and fell, pushing my cock all the way back inside her. I just asked her if we couldn't ride this accident out like before, but she doesn't want to cheat on you. So what do you say? It's not cheating if it's an accident, right?"

Another message: "You kiiinda need to answer quickly, bud...."

When you scroll down, there's a video, you press play. It's from the same point of view, Alyssa's sat firmly on Sid's hips, his cock clearly still inside of her.

Alyssa: "What....did...he...say..?" she says as she makes tiny motions back and forth, stimulating her pussy, filled with Sid's big cock.

Sid: "No answer yet....maybe that means he's fine with it...."

Alyssa: "He's....probably in class....ughhh..."

Sid: "You should just ride me until you cum...."

Alyssa: "I...don't want to....cheat on him...." she says, squeezing her large, aroused tits together for Sid.

Sid: "It was just an accident...Matt didn't mind the first accident..."

Alyssa: "He said....not to have sex...."

Sid: "This isn't really sex....you're just....using me to cum..."

Alyssa: "yeah...."

With that, it clearly took very little convincing to get Alyssa to place her hands on Sid's chest and start riding him, cowgirl style. As she starts bringing her hips up and down on Sid's cock, she starts breathing heavy, and moaning in sync with the sound of their hips slapping together as their sex escalates. You can't really see on the video, but they're clearly kissing deeply while she rides his cock.

Alyssa: "uughhnn....I fucking....love.....your cock...."

The video ends there, the final message is a picture of Alyssa's pussy, filled to the brim with Sid's cum once again. "I didn't mean to cum inside her, buddy. Just another accident."

Seeing this, you rush home, skipping the next and last class of the day. So pissed off you could stare daggers at Sid. When you get home, you hear the shower running. When you enter, you can see Alyssa on her knees in front of Sid, a stream of piss coming from the end, going into Alyssa´s mouth, and she's swallowing it! She just moves her eyes towards you, but obviously can´t say anything. Sid turns his head towards you, and while pissing in Alyssa's mouth, says.

Sid: "Hey bud, just a second while I finish up here...."

You: "What the fuck is going on here? I just saw the messages. You had sex again! And now....this?!"

Sid's stream dies down, all of it going down Alyssa's throat. "Good girl." he says while she gives the head of his cock a little kiss.

Alyssa: "Sorry baby....it was an accident. It was my fault, I wanted to cum, and Sid offered to grind on his cock....so it wasn't really cheating, I was just using him to cum."

Sid: "That's right. Think of me like a meat dildo...."

You: "It's not right, Alyssa. You cheated on me. I didn't give you permission."

She gets out of the shower and starts toweling off: "You're right....I was just desperate to cum. Being around Sid's cock all day, sucking his balls in the morning, getting massages from him....It just makes me so freaking horny.....I knew it was wrong. I won't do it again, I'm sorry. Please forgive me?"

You: "I...forgive you....but no more lessons with Sid. It's gone too far."

Sid: "That's fine. I've arranged a trip with your dad on his boat. We're leaving today...."

You: "But...I've got school...."

Sid: "Guess you can't come then...."

Alyssa: "Do you mind if I go, baby?"

Thinking about it, it would actually probably be for the best. Since Sid and Alyssa couldn't fool around so blatantly in front of your dad.

You: "No....I'll be fine here..."

Alyssa gives you a kiss and goes to pack. Sid taps you on the shoulder in a sort of pride. In just a couple of hours, they're leaving the door to go to the airport.

Alyssa: "Bye, baby...see you later!"

You: "Bye...have fun..."

Sid: "oh we will...."

After a few days, Alyssa sends you a picture. She's naked on your dads boat, sunbathing out on the ocean. "Hey baby, really enjoying the trip. Your dad is a great guy, he didn't mind Sid and I going nude for the trip. He even joined us!"

The thought of your dad seeing your fiancée naked, and her seeing his cock all day, makes your stomach twist, and you grab your cage instinctually. Alyssa sends you more pictures of her, and in the background you can see Sid and your dad naked, semi erect. Seems like things are very erotic on that boat.

You send a message back: "That's fucked up, Alyssa. I don't want my dad seeing you naked...."

Alyssa: "It's already happened now, so it's no big deal...."

You: "I guess..."

What followed were more pictures and messages of your dad rubbing sun tan lotion on Alyssa, and them playing truth or dare, and so forth.

Surprisingly, just a day later, Alyssa comes home, alone.

You: "Hey honey! What's goin on? You're home early." Then you notice she has tears in her eyes.

Alyssa: "I...broke it off with Sid..."

A massive wave of relief washes over you.

You: "What happened?"

Alyssa: "I...over heard them talking so badly about you when they though I was asleep. They talked about how stupid both of us are, letting Sid manipulate us and....use me for sex." More tears stream down her face.

You: "Oh my god, really? My dad said that?" Alyssa just nods.

Alyssa: "I've been so stupid, Matt. I let Sid come between us. I....think I just became addicted to sex and he used that against us."

You: "I'm....glad it's over now...."

Alyssa: "I have to admit something to you, baby. I hope you can forgive me."

You: "What is it?"

Alyssa: "They day I met your father.....he fucked me on our bed....Sid told me it's what we needed, and.....I did it because it excited me...."

You: "What?! My dad?!"

Alyssa: "Yes....and....we had sex on the boat, too....they used me for everything. Double teaming me almost every night...."

You: "Oh my god.....you cheated on me with my dad?!"

Alyssa: "I don't expect you to forgive me right away...but it's over now, I don't ever want to see them again, and I hope this will help you forgive me...."

She then takes out a little key. "I ripped it off Sid's neck before I left. I banned him from ever coming here again, and he's going to be staying at your dads..."

As she unlocks your cage, finally, another wave of relief washes over you, and your dick goes almost instantly hard from feeling the air around it.

Alyssa: "Come on, I want to have sex with my fiancée...."

After running to the bedroom and having some rather disappointing makeup sex, since you came in just less than a minute, you still feel like things with Alyssa are finally going on the right track. Sid is out of your life, and you never have to see your dad again.

A few months later, Alyssa is pregnant as she walks alone up to the altar. You decided to believe it was your baby after the makeup sex, but you and Alyssa both know who is the more likely father.

As you finally kiss as husband and wife, you feel, for the first time in a while, genuine happiness.

Alyssa is yours, and yours alone.
