Tara smiled as she listened to slow, rhythmic beating of Tim's heart while he ran his fingers through her hair and down the bare skin of her back. Nearly twenty minutes had passed since they'd had sex but she felt very little desire to leave his bed.
"Can I ask you something?" she said.
"Yeah, of course," Tim replied.
"How would you feel about Seth watching?" Tara asked.
Tim was silent for a few seconds and Tara worried that she'd just made a significant mistake. "Sorry, when you say watching, do you mean watching us?" he asked.
Tara sat up and smiled at her boyfriend. "You don't have to be okay with it, but I figured I'd ask, because Seth would be into it."
"Really?" Tim asked.
Tara couldn't help but laugh. Despite her repeated insistence that Seth was actually turned on by her having a boyfriend, there were times when it seemed like Tim just couldn't wrap his head around the idea. Tara didn't blame him for that - Seth was amongst a minority of men who found it thrilling to be cuckolded - but it still put a smile on her face when Tim seemed utterly astounded by Seth's desires. "Yes, really," she said. "I know you still find it hard to believe that Seth is actually turned on by this whole thing, but he really is, and I like to ensure that his fantasies come true."
"I know, I know," Tim said. "Sorry for my...reaction, I guess. I shouldn't judge your husband's desires."
Tara moved a little closer and gave him a kiss on the cheek. "No, you shouldn't, especially since I think we both know that you like that you're dating another man's wife. I think you really like that I'm married but that I have this incredible desire for you. I'm right, aren't I?"
"Yes," Tim admitted. "You're right. I do like that you're married and that you end up in my bed so often. I like that I seem to be able to make you cum so hard, that you really seem to like having sex with me."
"I love having sex with you, Tim," Tara said. "I really do. I love that my husband loves it too. It's all part of the fun for me, just like I think it's a part of the fun for you. Now, maybe it wouldn't be fun to fuck me while Seth is watching, but I'm asking because I think there's at least a chance that you'd enjoy it. Probably not as much as Seth would, but I do think you'd enjoy it."
"How would it work?" Tim asked. "I mean, would he be in the bed with us? Would he be sitting in a chair? Would he be directing the action?"
Tara ran her fingers through Tim's chest hair and kissed him on the cheek before resting her head against his shoulder. "It would work however you wanted it to work. I'm fairly certain Seth would enjoy any version of getting to watch us have sex, so I think it would be best to do it however works best for you, especially the first time. If you want it to be like he's not even in the room - like he's sitting in a chair in the corner - we could do that. If you're okay with him being closer, we could do that too. I know you haven't yet given this a ton of thought, but is there a version of fucking me while my husband watches that you'd enjoy more than any other?"
"You know, when you say it like that - me fucking you while your husband watches - it does sound good," Tim replied.
Tara looked up at him and smiled. She was fairly certain Tim was feeling just a bit of arousal, so she let her hand move down his chest and she took hold of his cock and stroked him slowly. "When you say good, do you mean it's a little bit of a turn on to think about fucking me while my husband is watching?"
Tim nodded.
Tara felt like she had a good grasp on what turned Seth on with regards to his cuckolding, but she was curious to dig a little deeper into Tim's enjoyment of dating - and fucking, of course - a married woman. Not all men would have been into a relationship like the one they had. Tim was into it, though. He was turned on by it, even if he wasn't fully in touch with that yet.
"Do you like the idea of making me cum while my husband watches?" Tara asked. "Do you like the idea of him seeing just how good you make me feel, how hard you make me cum?"
"I do," Tim replied as his cock grew a little in her hand. "I love how hard you cum when I fuck you, Tara. I do. I love how much you seem to want me."
"And I love how much you want me," she replied. "My husband loves that too. He loves that his wife gives her boyfriend such intense pleasure. He loves that his wife's boyfriend can't help but want to fuck her as often as possible."
Tim turned towards Tara and kissed her. She offered her tongue and he took it as his cock fully came to life in her hand. "And I love that you're almost always happy to drop whatever you're doing and come to me when I want you," he said.
"Do you want me right now?" Tara asked. "Do you want to fuck me?"
"More than anything," Tim replied.
"And if my husband was here, where would you want him? Would you want him sitting in a chair in the corner, or would you want him up close so he could see how well you fuck his wife?" Tara asked.
The smile on Tim's face was all the answer she needed. "I'd want him close," Tim answered, confirming her suspicions.
"Put on a condom," Tara said.
Tim rolled to his side, grabbed a condom from his nightstand, and had it on his stiff cock in a matter of seconds.
Tara imagined Seth in the bedroom and wondered how he'd like to watch her get fucked. She crawled towards the foot of the bed and then looked over her shoulder and said, "Take me from behind. Fuck me as if Seth was on his knees at the foot of the bed, looking up at me and watching as my boyfriend fucks me."
Tim smiled and his eyes lit up with desire as he moved into place. He rubbed the head of his cock over Tara's pussy - she was soaked - and slipped inside her with ease. He grabbed her hips and almost immediately started fucking her hard and fast. Tara pushed back on him with every thrust and moaned at the unexpected pleasure of being taken from behind with such vigor.
"That's it," she said. "Fuck me, Tim. Fuck me while he watches. Fuck me while Seth watches!"
Tim fucked her with an uncommon kind of aggression, proving that he was thoroughly aroused by the idea of Seth watching, which put a smile on Tara's face. That meant it wouldn't be too difficult to make Seth's fantasy of watching into a reality. As it turned out, Tara was keener on having Seth watch than she expected, as the mere thought of it had put her in a heightened state of desire, a state that she was eager to pursue further with her boyfriend and her husband. With any luck, she'd be able to make it happen soon.

"I crawled onto my hands and knees and faced the foot of the bed," Tara explained as she sat across Seth's lap on their couch. "I told him to fuck me from behind like you were watching. I told him to take me - to take your wife - while you watched from the floor."
Seth ran his hands under her shirt and up her back. He applied gentle pressure and Tara leaned forward to kiss her husband as she ground her hips into his crotch. She felt the stiffness of his desire pressing into her through his pants and it filled her with delight. She'd fucked her boyfriend twice and it was almost guaranteed she was going to fuck her husband fairly soon, ensuring three intensely satisfying sexual experiences for her in the span of a single day.
"What did he do?" Seth asked.
"He moved behind me, slipped his cock inside me, and fucked me hard from behind," Tara said. "My boyfriend fucked me so hard, baby. He fucked your wife so hard. And it felt so fucking good."
Tara pulled Seth's shirt off and he did the same for her. She hastily unhooked her bra and leaned forward. Seth took one of her breasts in his mouth and flicked his tongue back and forth over her nipple as she continued to grind in his lap, eliciting a steady stream of moans.
"I imagined you were watching, Seth," Tara said. "I imagined you were on your knees on Tim's bedroom floor and watching him take me from behind."
"Was that...was that good?" Seth asked.
Tara smiled and nodded as she took her husband's head in her hands. "It was," she said. "Particularly when I imagined you kissing me as he fucked me from behind. I imagined feeling your lips against mine and your tongue in my mouth. I imagined moaning as we kissed, moaning as my boyfriend fucked me while you watched. It felt good, Seth. It did. It felt so good."
"And Tim, did he enjoy all of it?" Seth asked.
Tara nodded again. "He did. I think he might have cum harder the second time we fucked, the time when we both had the idea of you watching on our minds. I think he really likes that he's dating a married woman, that he's regularly fucking another man's wife, and that he makes that other man's wife feel so good when we have sex."
Seth reached under Tara's skirt and grabbed her ass as he moaned. She watched a certain kind of pleasure wash over his face and she was convinced that Seth loved that her boyfriend was so into dating and fucking a married woman.
"Do you like that Tim enjoys making your wife feel so good, Seth? Do you like that it turns him on to know that he's fucking a married woman, that sometimes I've left my husband to go to him on a moment's notice, that sometimes it seems like I just can't resist the allure of being able to fuck him, no matter what else is going on in my life?" Tara asked.
Seth responded by tightening his grip on Tara's ass and standing up, which struck her as an impressive feat of strength. He set her on the couch and pulled her panties off with remarkable swiftness. His pants and underwear hit the floor a moment later and he moved between her legs and slipped his cock into her soaking wet pussy.
"Fuck me, Seth," Tara said. "Fuck me hard."
Seth delivered the hard, fast fucking she craved. He pounded her with a wondrous kind of vigor and each thrust send waves of pleasure through her body. She wrapped her legs around him and held Seth close as he seemed to lose himself in the overwhelming lust he felt. Tara felt no need to fill his head with more dirty talk. It would have been a distraction. Instead, she simply enjoyed the beautiful, deeply pleasurable sex with her husband.
They both came quickly, as tended to happen when they were turned on in that overwhelming manner. Tara climaxed first and screamed loud enough that someone on the sidewalk outside the house might have heard. She wrapped her legs tightly around Seth and he buried his cock inside her and came soon after. She held him close and showered his neck in kisses as he unleashed his load in her pussy.
"Holy shit," he said between heavy breaths. "Tara, that was astonishing. You're...you're amazing. I know I say this a lot, but I'm not sure what I've done to deserve you as a wife."
Tara laughed and kissed him on the lips. "That's very kind of you to say," she replied.
"Your boyfriend is lucky too," Seth added. "I can't say for sure, but I'll bet he's having the best sex of his life with you, which really says something about your ability to make the sexual dreams of men into reality."
"Speaking of which," Tara said as Seth remained inside her. "Do you want me to arrange an opportunity for you to watch? Do you actually want to go through with it?"
"I do," Seth answered. "I'll admit that the idea of meeting Tim and watching him fuck you makes me a little nervous, but it's also really exciting, so yeah, I think I want to do it. How would it work?"
Tara ran her fingers through his hair and stared into her husband's eyes for a moment before saying, "I told Tim that for the first time it would essentially work in whatever way he wanted it to. He could decide where you were and how involved you got to be. He could even decide if you get to masturbate or if you just have to watch while fully dressed. I know that might not be perfect, but I think it's the best choice for the first time."
Seth nodded. "I'm okay with that. I get that it might be pretty weird to have your girlfriend's husband sitting there and watching while you're having sex."
Tara smiled brightly.
"What? What's with the smile?" Seth asked.
"I just kind of love that I have a boyfriend," she replied. "I don't know, sometimes it just puts a smile on my face to think about that, you know? It's definitely not something I ever thought I'd have as a married woman, but now that I do, I really like it."
"Well I do too," Seth said. "Obviously. And, well, this idea just popped into my head, but maybe we could go shopping to get you some lingerie to wear for this night with Tim. That might make it feel like a little more of a special occasion, you know?"
Tara smiled. "Yeah? You'd be willing to do that?"
"Honestly, I'd really enjoy doing that," Seth answered. "There's something kind of sexy about buying something beautiful for you to wear for your boyfriend."
Tara could see the excitement in Seth's eyes, so she had no trouble believing he'd enjoy helping her look good for Tim. "Okay, then we'll make sure to do that. Let me arrange things with Tim and then we can go lingerie shopping."
"This is so exciting," Seth said. "I swear, I feel like I could fuck you again with just a little bit of a break."
"Then let's do that," Tara replied almost immediately.
Seth looked surprised. "Seriously? You'd be up for going again? Wouldn't that be four times in one day?"
Tara bit her lower lip and nodded. "Is that too slutty?"
Seth shook his head. "There's no such thing."
"Good. Let's go to the bedroom. I'll get cleaned up and then we can work on getting you hard for another round," Tara suggested.
Seth pulled out, grabbed his clothes, and headed for the bedroom with Tara close behind. She wasn't just offering another round for his benefit, either. She was in the mood for another orgasm and Seth was fully capable of ensuring she came hard, so Tara was going to take full advantage.
