The next day all three of my roommates came on my girlfriend’s face.
It wasn’t all at the same time and it was pretty much within the rules, but on some level it still bothered me. Dominating Mia like I did the previous night was fun in the moment, but it still felt uncomfortable leaving the house that morning knowing what was going to happen. It felt like I was being taken advantage of in some way. Or that Mia was being taken advantage of. Or maybe that Mia was taking advantage of me. I couldn’t quite place the feeling, but it was unsettling.
Of course, that feeling didn’t stop the thrill that charged through my body when Mia texted me at 10am that she’d received her first load of the day from my roommate Mark: Facial #1 I hope u like it sweetie!
I did, in fact, like it. I liked it so much that I ran to the bathroom to rub one out while I looked at my beautiful girlfriend’s beaming round face frosted with another man’s spunk. The picture she sent me was a selfie, a streak of semen shot across one cheek, a smattering on her nose, and at least a few globs pooling on her tongue. She was still wearing her shirt and seemed alone in the room, which meant that my roommate simply walked in, blew his load on her face and walked out.
My girlfriend is a dirty fucking whore, I thought to myself as my own cock spasmed in my pistoning right hand. The mental image of my love being nothing more than a cum target for multiple men was both the trigger for my own orgasm and the thought that bothered me as I left the bathroom after cleaning up. Why did this turn me on so much? Shouldn’t it just upset me?
I tried to shake the vexing thoughts loose by reminding myself that this was a temporary situation. All Mia was doing was providing her room and board in kind while she was unable to find her own place. Moreover, while the “labor” she provided was certainly lewd, there were strict rules that would ensure things did not get out of hand. The rules were that my roommates could use my girlfriend once a day to get their rocks off by either cumming on her face, tits, or ass. They were not allowed to see her pussy, and under no circumstances would they touch her or would she touch them. These rules were clearly set forth to all parties involved the previous night, and I reinforced them with Mia in the morning before I left for work. Everyone was on the same page, and there would be no expansion of or amendment to these regulations.
Except ... as I settled back into my chair and tried to get some work done, my mind wandered back to the picture Mia sent me that morning, in particular the semen Mia had on her tongue. I hadn’t explicitly told her that she couldn’t taste it, nor had I told them they couldn’t shoot off in her mouth, so I guess that was a loophole. Mia loved the taste of cum and of course who wouldn’t want to watch a hot girl swallow their nut? Obviously they were going to try to do it there. I shook my head, frustrated at my lack of foresight.
“You OK, Frank?” a voice snapped me out of the haze. It was Britney, the perky blonde office receptionist, walking near my cubicle. “You look annoyed.”
“Oh, yeah, just trying to figure out this new expense report system,” I lied, searching for an excuse for my visible agitation. In truth I was far too junior to have any expenses to report. Nevertheless, that fib seemed to satisfy Britney.
“Gotcha! Yeah, such a pain,” she laughed. “Let me know if you need help with them! The bosses usually just give me receipts and I fill out the reports for them. So whenever you get too backed up don’t be afraid to dump your load on me!”
I nearly choked at her phrasing, but tried not to betray my amusement. Britney was no older than me and did not seem dumb or naive. She had to know what that meant ... right? Was she joking with me? Or was she ... flirting?
“Thanks,” I said awkwardly. “Will do.” A text notification in my pocket reminded me that it was likely someone else was dumping their load on my girlfriend. I decided to save it for later. I knew it would turn me on like crazy but didn’t know if I could pull off two long trips to the bathroom back-to-back in rapid succession.
It took a herculean effort but I managed to start concentrating on my work a bit more, and even managed to get into a bit of a groove with my spreadsheets. I got a few more texts from Mia but decided to put them off as well. The thought occurred to me that maybe I should save them for when I get home and open them with Mia there. That way if there was something that bothered me about her pictures, like the fact that she was swallowing their cum, I could bring it up right then and not stew about it all day. Honestly, that seemed like the best way to go.
1pm hit and I took lunch, hitting up a nearby taco truck. I didn’t want to be tempted by my phone so I put it on silent and ate in a nearby park while reading a book. It was a SciFi novel set in outer space, and I relished the opportunity to get out of my anxious and confused headspace for a bit. By the end of the hour, I was thinking about galactic political intrigue and cruiser battles, not the weird living situation in which I found myself. It felt wonderful.
As I was walking back into my office building I glanced at my phone. There were 15 new texts and 2 missed calls from Mia, a clear sign something was wrong. I ducked back out into the parking lot and called her back immediately without checking the texts.
“Hi is everything OK???” she asked when she picked up the phone. I could tell from the tone in her voice that she was very nervous and perhaps a little upset.
“Yeah, why wouldn’t it be?” I responded. “What’s up?”
“Oh thank god.” The relief in her voice was palpable. “I just didn’t get any response to my texts and worried you were mad at me.”
“I haven’t looked at your texts yet. Why would I be mad at you? Did you break the rules?”
“No! I mean, I don’t think so. I just ... well, I am scared of upsetting you, is all.”
“Mia, if you were really scared of upsetting me you never would have agreed to this crazy deal. This whole situation is upsetting!” I said tersely.
There was a pause at the other end of the line. When she eventually spoke, there was a quiver in her voice that suggested she was starting to cry.
“I ... I’m sorry. I just agreed to it and thought it would be fun and would turn you on. And yesterday you got so excited when I sent you those texts and that was so hot for me to know you were jerking off at work and then when you got home and fucked me like you did ... I thought you liked it. I thought you were having fun too. Oh god.”
She was really crying now. I felt terrible for that. The truth is she was right. I ... I like it. It ... turn me on. I WAS having fun. I was just having a lot of conflicting feelings about it at the same time.
“Honey, don’t worry. I’m sorry. I ... do like some parts of it. A lot. I just have some feelings about it I have to get through as well. I didn’t look at your texts because I didn’t want to jerk off to them at work again today.”
“Again?” she queried as she regained her composure. “Does that mean you already jerked off to my texts today?”
I sighed with resignation. “Yes, once, to your first picture. It was really sexy and got me off super fucking hard.” Mia squealed in glee on the other end of the connection. “It’s just that I have to do it in the bathroom and it’s right next to Brea’s desk and I do need to get some actual work done, you know?”
“Oh that’s suuuuuch a relief,” she said, with full sultriness returning to her voice. “I thought you didn’t want me to text you anymore when your roommates used me as their cum dump. Because I like texting you about it, sweetie.”
I was getting hard again thinking about it, despite the reminder that it was my friends who were getting their rocks off. It was like all of my previous anxieties about the situation went right out the window once my libido was triggered, and Mia was a master at triggering it.
“No, slut,” I responded in the most dominant way I could muster. “The rules say you will continue to text me pictures, as needed. You will follow the rules.”
“Thank you siiiirrrr!” Mia practically sang in response. “Let me know how you like my texts when you do look at them!! Hopefully we can figure out a way to get you more space to enjoy them at work in the future, but I won’t keep you any longer bye I love you have fun!”
The line clicked dead. I waited a minute or so for my erection to subside to acceptable levels, then returned to my desk, and tried to calm down from the phone conversation. It was reassuring that Mia confirmed that she hadn’t broken any rules. Or ... did she? What was it she said again? That she didn’t “think” she had broken them. My heart sank at the same time my head spun at that ambiguity. Had they touched her? Had she touched them!? Either way would be a clear violation, so I could probably be sure THAT hadn’t happened. Maybe she just misspoke and I shouldn’t worry about it.
Once again I tried to concentrate on my spreadsheets. Once again, my imagination lingered back to Mia and her texts. I decided I needed to look, just to put my mind at ease. I also decided that I probably needed some privacy, so I waited for the bathroom to open, scooted by Brea’s desk, and locked the door.
I put in my earbuds and sat down, unbuckling my belt and lowering my fly. Scrolling past the last several messages asking me if I was OK, I went to the first unread text.
Facial #2, I hope u like it tooo! This time David asked to look at my butthole while he jerked off. when he got close he asked me to take off my shirt and I thought he was going to bust on my titties but he blew his load on my face instead!!
The photo looked like a porno spread. Mia was sitting up on the bed and looking proudly at the camera while covered in white gooey cum, her large breasts and hard pink nipples jutting prominently upward. At first glance, I thought she was naked but as I zoomed in I saw the thin strings of a tiny black thong stretch around both of her wide hips. I began to work my cock in earnest thinking about my beautiful girlfriend bending over and pulling aside her G-string to display her tightest hole for another man. My mind imagined him kneeling and craning his neck to look at her ass as closely as possible while he cranked off. The notion that he then told her to take off her shirt and get down on her knees before painting her pretty face with his spunk was almost overwhelming to me. If I wasn’t intentionally trying to hold back my orgasm to see the entirety of Mia’s texts, I would have shot off myself.
Instead, I slowed the pumping of my right hand and clicked away from the picture. My heart was pounding as I scrolled past the next few texts until I saw what I was looking for. It wasn’t a picture this time, it was a video, a lengthy one, a little over six minutes long. The text that accompanied it said: Hope u like this one it’s really hoooottt!! and several heart emoji. I took a deep breath and hit play.
The screen showed Mia on her knees, wearing only the same thong she wore in the previous picture, and it was taken from the point of view of what was certainly Alex. His cock, every bit as big as Mia described it, was pointed in her direction and he was stroking it languidly. Mia wasn’t just going to show me some other boy’s cum on her, she was going to make me watch him do it. My own cock could not be harder.
“You like watching me jack off, don’t you?” asked Alex’s disembodied voice.
Mia nodded mischievously. “Oh yes, you have a beautiful cock and I like watching you play with it.”
“I’ll bet you’d like to suck on it wouldn’t you?”
“That’s against the rules, silly.”
A wave of relief washed over me. She was following the rules!
“Yeah but I can tell a slut like you loves to suck dick” he said as he moved his cockhead closer to her lips. Reflexively, she licked her lips and locked her bright blue eyes on the camera.
“I do, I love sucking cock a lot, especially when they’re big and fat like yours. But today I’m not going to do that and instead I’m just going to let you empty your balls all over me.”
The scene was ludicrously hot, and whatever conflicted feelings I might have had about my girlfriend saying nice things about my friend’s member were washed away by a torrent of lust. I even felt a small twinge of disappointment when Mia said she wasn’t going to blow him. What was going on with me?
Alex laughed. “Ok slut, where do you want it?”
“Anywhere you want. You could cum on my tits. You could do it on my ass. If it’s up to me I want you to give me a big messy facial. I’ve already had two today and want one more. Can you do that for me? Can you cover my pretty face?”
“I’ll think about it, slut. Why don’t you play with your titties for me while I make up my mind.”
Alex was taking control and dominating my girlfriend, and for whatever reason I loved watching every second of it. Mia cooed and began kneading her double Ds and pinching her nipples, eventually bringing them up to her mouth for her to lick them. Then she cradled both of her breasts in one hand while tracing her cleavage back and forth with the other as if she were stroking an invisible cock nestled between them.
“I bet you’d like to fuck these big tits, wouldn’t you?”
“I probably would, slut. Do you let your boyfriend do that?”
“Anytime he wants. I love it. He says they’re heavenly.”
She was right. I do say that. And they are.
