“Bro, we need to talk,” said Alex as I walked into the kitchen. He was sitting at the hand-me-down kitchen table we had in our adjacent apartment dining area. David and Mark were there too.
I could already sense what they wanted to talk about, but I played dumb and asked, “What is this about?”
“C’mon, Ben,” laughed Mark. “You know it’s about Mia.”
“You know we like her,” David continued. “She’s great and all, and we all feel really bad about what happened to her apartment but it’s been almost a month. What is going on?”
I had dreaded this conversation.
Mia was my girlfriend. Her flat had burned down 25 days ago, and since then she had been living in our small four-room apartment in a not-so-great neighborhood. Apartment number 23, to be precise.
“I’m sorry guys, she just needs a little while longer to figure out what to do next,” I said, trying to keep my voice from betraying any hint of reticence.
“Wait wait wait ... last week you told me she was waiting until the insurance money came in,” said David.
This was why I was dreading this conversation. I swallowed hard. “Yeah, um ... I guess there was no insurance. Her roommate forgot to pay for it.”
“WHAT!?!” shouted Alex. “Are you fucking KIDDING me!?!’
“Shhh, man, keep your voice down she’ll hear you.”
Our apartment building was over 80 years old, was cramped as hell, and had comically thin walls. Anything over normal volume was audible almost everywhere throughout the flat. Mia was in my bedroom at the moment, probably playing games on her switch. There was no doubt she would hear if this volume kept up.
“Her hearing us is part of the fuckin’ problem man,” said Alex, his voice softer but just as stern. “She’s always here! Doesn’t she have a summer job?”
“She hasn’t been able to find one. I don’t know, man.”
My roommates shared a knowing look, rolling their eyes.
“What the fuck do you guys want me to do, throw her on the street?!” I said tersely, while trying not to shout.
I was at my wit’s end and didn’t see a way out of this. To be fair, I understood why my roommates were upset, but I didn’t want her to feel any worse than she already did.
“She’s got to do something around here, Frank,” said Mark. “It’s not fair to have her here all the time without giving back.”
“Yeah, I get that, but she doesn’t have any money. What do you want her to do? Cook? Clean? Do chores?”
“Naw, man,” answered Alex. “We handle all that stuff ourselves. We want something else.”
“Okay. What is it?”
Nothing could have prepared me for what Alex said next.
“We want her to let us jerk off on her once a day.”
“WHAT!?” I was stunned. Incredulous. Horrified. “Hell no, and fuck all of you.”
“Come on dude! We know she likes it, we can hear you guys fucking twice a day and she’s always begging you to blow it all over her.”
“I ... I don’t know what you’re talking about,” I said.
That was a lie. I knew exactly what they were talking about, because it was true. Mia was a shy, bookish, nerdy girl, but in bed she was insatiable, perverted, and most of all LOUD. Once she got going the only way to quiet her down was to shove a cock in her mouth and even then she’d moan and beg me to use her like a slut, or a whore, or a dirty little hole for me to use. And, as Alex pointed out, she loved imploring me to cum on her. Tits, ass, face, pussy, she loved my jizz anywhere and everywhere and she was not shy about asking for it. It was her favorite way to get me off, and it worked. And everyone in the apartment knew it, because they had to have heard it echoing through the apartment.
David spoke up next. He was usually the calm and reasonable one, but he was resolute with the other roommates. “Look, man, we can’t watch porn with her here because the walls are so thin, and she’s always walking around in those tiny little shorts and with her massive tits in a t-shirt with no bra. That plus all the fucking you guys do ... it’s just too much! I’m going fucking crazy here. Either she helps us out or she’s got to go.”
“I’m not going to pimp my girlfriend out to you assholes. No way.”
“Dude, we’re not going to fuck her,” said Alex. “She’ll just come to each of our rooms once a day and we’ll whack off on her. No big deal. Seems like a fair trade for a free place to live.”
“You’re all out of your fucking mi...”
Mia’s voice interrupted me mid-protest. “I’ll do it.”
I spun around to see my beloved girlfriend. Her blonde hair cascaded down past her shoulders, framing her oval face, while her piercing blue eyes scrutinized expressionlessly thru a pair of black-framed glasses. As David had predicted, she was wearing a pair of shorts and a t-shirt without a bra. Despite this, her firm D-cup breasts were high on her chest, nipples erect and pushing against the fabric.
“Mia, honey, you can’t be serious...”
“They’re right, Frank. I need to give back. I don’t have money or a place to live. So I have to do something, and this is fair.”
“Hell YES!” exclaimed Mark.
“Shut the fuck up!” I shouted. “Babe, no, let’s talk about this. I am not going to let this happen while I’m here.”
“No problem,” said Mia. “We’ll do it while you’re at work.”
My mouth dropped open. Mia leaned up and kissed me on the cheek. “It’ll be fine,” she whispered in my ear, reassuringly. She then turned to my roommates and said “OK here are the ground rules. I’ll be topless only. You can shoot your load on me anywhere above my waist, but below my neck. I’m not going to touch you or blow you or whatever. You will not touch me anywhere without my permission. You’ll get 15 minutes once a day, and if you can’t get off in that time it’s your problem. Deal?”
“Deal,” said Alex.
“Deal,” said Mark.
“Absolute deal,” said David.
“Babe, no!” I said to deaf ears.
“Frank and I are going to go into our room to talk now. And have sex.,” said Mia, taking my hand and pulling me away from the kitchen. “See you boys tomorrow.”
When we got to our room I was so furious my hands were shaking. When she saw my expression she told me softly to calm down and we could discuss things. The conversation was kind but firm. We sat on the bed and she held my hand gently. She calmly explained that my roommates were right, that she had no money and nowhere else to go, and that she didn’t have any real prospects of changing either of those things. She mentioned that she knew that it would be months before I had saved up enough to get a place of our own, and the best thing to do would be to figure out a way to make this work in the short term.
“Finding a way to make it work is one thing,” I said, my eyes burning daggers into my bedroom’s ratty green throw rug. “But why this? Let me go back there and see if there’s another thing you could do. I don’t want those guys ... you know ... doing that.”
Mia reached out and tilted my chin upward with her hand so that I was looking at her. Her eyes were filled with mischief and lust. “You don’t want your friends to blow rope ... after rope after delicious rope of their hot white cum all over my big, fat titties? Are you sure, Frank?”
“Yes of course I’m sure,” I said, but deep down I wasn’t quite so certain.
“See that’s a little surprising given how much you love it when I tell you stories of me being a whore. Like ... how many times have you asked me to tell you about the times I fucked other dudes before I met you?”
I did, in fact, ask her about those stories a lot. Sometimes when I was plowing into her impossibly tight pussy I asked her to tell me about the time she blew two different guys at a party ... or when she gave her ass to a guy for the first time ... or when she flashed her tits to her cousin. But I couldn’t admit that. Not now. I stayed silent.
She continued. “And how many times have you asked me whether anyone else has cum on my face right before you blow your load on me? It’s been quite a few if memory serves. The funny thing is that when I say no they haven’t you always seem a little ... disappointed.”
She was right on all counts. I did ask. More than once. And I was disappointed. It would have turned me on a lot if she had said yes. In fact the story of the two guys at the party involved one of them being too drunk to get it up and another being interrupted before he could finish, but in my mind I often fantasized about both of random dudes unloading all over her at the same time. I was caught, and nodded to her meekly.
“But honey, that’s different,” I responded, mustering up the last bits of my resolve. “Those are fantasies, and those other things you did happened before we were together. It’s just not the same.”
“You’re right,” Mia conceded, her big blue eyes sparkling with excitement. “This would be very different. But it might also be ... pretty fun?” She stripped off her shirt and laid down on the bed, holding her massive jugs in each hand. “Come on over here and titty fuck me while you think of how sticky with other boys’ cum these are going to be tomorrow.”
I was powerless to resist. As I pumped my thick seven inches between her tits she regaled me with bawdy pornographic stories of other dudes who had enjoyed them too. “They all loved fucking my tits until they came,” she purred “and I know you do too. Do you think that your roommates will like it? Of course they aren’t allowed to touch me ... let alone pound my chest meat like you are now. But you know they’ll want to. They’re going to want to use every bit of my slutty body like you do. But instead all they’re going to do is blow their hot loads on these. Do you want me to take pictures? Of their pearly white jizz all over these huge ... fat ... tits?”
That did it. I thrust hard upwards between her chest and began to cum, the first volley spurting high and hard across the length of her face. “Yeah shoot it all over me!” she exhorted. I complied, rutting wildly into her cleavage and loosing every ounce of semen I could into the warm caverns of her ample chest, as well as her delicate collarbone, and neck. She smiled up at me. “Ohhh sweetie, you’re going to like this arrangement a whole lot, I think.”
The next day at work was agony.
I had gotten up early and left before any of the guys would wake up so I didn’t have to face them. A big part of me was still pissed that they had forced us into this situation. Another big part of me was upset that Mia had said yes. A third big part of me was furious with myself for letting it happen. Still, there was a part of me, perhaps a bigger part than I was willing to admit, that was a teensy bit excited ... even aroused. I didn’t know what that meant, so I shoved those feelings down as far as I could and headed to the office.
I worked in a small office with only seven other people and got there well before anyone else for once. My cubicle was mostly private but someone could (and often did) walk up behind me without me noticing. Because of this I told Mia to text me about what happened when it happened (I claimed it was to make sure she was safe and I think she might have even believed that a little) but to wait to share any pictures she took until after I got home.
Suffice it to say that my productivity on this day was poor. Every spreadsheet I looked at, every piece of code I tried to write, every form I filled out turned into alphabet soup after mere minutes. My brain was a mixture of anxiety and dread and horniness and uncertainty and excitement. Felt like I checked my phone for a text every five minutes but got none. At lunch I could barely eat. The time ticked by ever so slowly.
Then, at about 1:30, the thought occurred to me that maybe it wasn’t going to happen after all. Maybe the guys would chicken out or Mia would change her mind. After all, they could have done it at any time until now surely one of them would have tried if they were actually going to go through with this insanity. In fact, I thought, all of this was probably just a prank that David thought up to fuck with me, like the time he paid a stripper to invite me back to her place only to pop up and laugh when I asked her what time her shift ended. Fucking David! Hahahah. This was all a joke and I was never going to hear the e...
My phone buzzed. I looked. My home screen said SMS FROM MIA
My hand trembled as I reached to open it. I took a deep breath, steeled myself for the worst, and put in my passcode. The text was short, nevertheless I was so keyed up that it took me a few tries to make sense of it.
I have Mark’s cum on my tits
My head spun. It wasn’t a joke. It was real. One of my roommates had used my girlfriend as a cum target. His semen was still on her at this very moment. I could feel my heart beating wildly in my chest. I could also feel my cock start to swell.
“Okay.” I managed to respond. I didn’t know what else to say. “Are you alright?” I added.
Yes! It was all within the rules. He came in, I took off my top, and he never touched me. I got on my knees and he just jerked off on my boobs. Then I texted like u asked.
The mental picture of my sweet girlfriend on her knees waiting to accept the semen of another man was overwhelming. My cock was so rock hard and throbbing that I worried I might blast off in my slacks.
“Thank you for telling me. Did you do anything else?”
No. Well, I like talked dirty and played with them to get him in the mood but I didn’t touch him if that’s what u are asking.
My heart was pounding. I wanted to know so much more and also didn’t want to know and I didn’t know what to ask or think or say. I did a quick scan of the office and saw that no one would be walking into my cubicle. I took a deep breath and asked what I wanted to know: “Is it a lot of cum?” A few seconds later I got a response.
YES. I am COVERED
This was torture.
Do you want to see?
This was beyond torture.
“Yes but give me a minute.”
I desperately wanted to see but not at my cubicle. Scanning the office quickly again I saw that people were mostly focused on their work at their desks. The office had a single stall bathroom which looked to be unoccupied, but I had to pass by the desk of the secretary Britney to get to it. I tried to shift my diamond-hard cock in my slacks so that the tent would not be too noticeable, and made a beeline for the bathroom hoping against hope that Britney, herself a stone cold fox, would not look up at my obvious erection as I passed her desk, though I was in such a hurry that I made no effort to confirm it.
Locking myself in the single stall and turning the fan on to hide whatever sounds I could, I put my earbuds in, undid my belt to unleash my uncomfortable erection, and texted my girlfriend back. “Show me.”
A picture popped up on my screen. She was right. Her massive E-cups were indeed covered in streaks and globs of pearly white jizz. It was not the first time I had seen that glorious sight, but it was the first time the cum wasn’t my own. My right hand started pumping my own drooling cock.
“Oh my god that’s hot.” I responded.
Where are you?
“The bathroom”
Are you jerking off at work to me all covered in spunk?
“Yes”
Good then you’re going to love this
A video popped up. I hit play. Her phone was recording her from her desk, and she cupped both of her fat cum splattered tits in her hand as if she was offering them to the camera, jiggling them ever so slightly so the white translucent joy juice slid this way and that over her massive globes. One long tendril of cum dripped down the slope of her left breast to her light pink areola and hung tantalizingly on the eraser-sized nipple. Then, to my great delight and slight horror (or great horror and slight delight I couldn’t tell which), she moved her right hand to her left nipple, scooped the wayward glob of genetic material in her finger, and and with a wicked smile brought it to her smirking lips. She opened her mouth. A sound escaped my mouth that was both a gasp and a groan. We had not talked about her eating any of my roommates’ cum! This was an escalation and I knew I should be furious!
But still, the minute I saw the hot white spunk of another man touched my girlfriend’s tongue a torrent of my own orgasmic emission began spewing forth from my cock with wild abandon. I painted the far wall of my office bathroom stall with streak after streak of evidence that I enjoyed the lewd display of my girlfriend tasting a friend’s jizz.
“Fuck” I texted her.
Did you cum?? Can I see??
I didn’t respond because I didn’t know what to say. I had already started wiping my semen off the wall. When it was reasonably clean, I started texting her back. I had gotten as far as typing out “Yes but I can’t show you and I’m not sure you should be tasting it because we hadn’t talked” when another text from Mia popped up.
I hope you came hard baby but Alex is here so I’ll tell u when he’s done.
I deleted the text I had typed out and just said “OK”
Despite my extremely recent ejaculation, my cock surged again to a full erection. At this very moment my sweet girl was almost certainly on her knees with her tits out waiting to be painted with a second load of the day. I was always jealous of Alex, he was tall and dark and handsome in ways that I was not. He always got plenty of girls, and now he was getting my own. Or, well, sort of. While the fires of envy were growing in my belly, I could not deny that the fires of desire were growing in my loins.
I began jerking off, imagining what was taking place. I looked at the picture again. I watched the video again. I wondered if she had cleaned Mark’s cum off before letting Alex in or whether she left it on so he could add to the copious volume? I wondered if David was waiting his turn. Maybe he was watching. Mia had said that she had played with her tits a bit for Mark. Did that mean she was holding them? Did it mean she was licking them like she did when she wanted to get me off? Was she loudly begging for this other man to cum on her like she did with me? Did she...
