[M4F] SIZEable - Dating App for the Very Well Endowed

NSFW RP - Ongoing

“SIZEable” is a hot new mobile adults-only dating app which has gained a particular reputation as rather discerning about membership, spread by word of mouth and social media. Those in the know quickly get the name’s meaning - a service that caters to the well endowed, and has a profile sharing setup to help their primary clientele control how their more intimate details are shared.

The public profile shows for everyone and doesn’t look especially different from other dating services. If anything, it’s more sanitized because there is a second part of the profiles that is only shared between mutual likes that provides more of the juicy details. If your character has gotten approved with the service and has a taste for the greatest offerings of endowment, then the one subtle detail to the profile below which will stand out to her in her swiping is the platinum status indicator appearing with his avatar picture. This something rarely seen on male accounts, and something that specifically can’t be bought. (Note: the profile text areas in brackets are either described visuals or RP notes.)

From the ‘SIZEable’ app Public Profile:

Name: Blake Johansson
Sex: Male
Age: 24
Height: 6’1”
Weight: 174 lbs.
Education: Bachelor’s or equivalent
Location: [Negotiable, default is Los Angeles area]

[There are a few photos on this part of the profile. The head shot shows a decently handsome face, strong nose and noticeable jawline, clean-shaven with a loose head of ruddy hair left slightly unkempt. His light blue eyes are piercing, and his smile is soft but rests on a firmly masculine countenance. The others are fairly casual in nature, his upper body lean but firm under old concert t-shirts or silk button-up shirts stretched on his broad shoulders, the man’s swimmer’s build easily discerned. A few of the shots are full-body, always showing a camera slung over his neck or shoulder resting over the base of his chest. Below that, Blake wears loose-fitting jeans or khakis, but the discerning eye can easily make out the telltale signs of bulging in his crotch, a rather round and prominent arc at the apex of inner thighs, and a pressed slab against his right thigh, notably thick and reaching about halfway between his crotch and knee.]

Section “Describe Yourself”:

Who knew adulting could be so hard? Adjusting to the post-college life, your friendly neighborhood photographer is looking for some friendly fun. I am living a very sizeable life, and hope anyone I can meet here is prepared for that. The only D&D I’ve got is the RPG; that’s not a requirement, but it will be worth bonus inspiration. Work schedule is flexible but weekends can be busy with weddings and the like, but that leaves evenings free for whatever.

[This is all that is visible at first most of the time. However, Blake has been somewhat active on the app for a while, and if you’ve had your profile on for a bit, you might just be lucky enough for the following to appear. Details for what I and Blake would be responsive to provided after.]

Section “Describe Yourself Personally”:

Before, getting into my wants, let me first cover some common questions/complaints. The listed sizes are real, and yes, they normally can’t be typed into the form because they’re too large. I was specially verified by the company and have to contact them for any growth updates. I don’t list ‘hookups’ because, frankly, one time is never enough with a partner to be satisfied, and I am hoping for more than a simple fuck at this point. That said, I can’t say it’s entirely off the table, but I reserve a right to be picky.

I’ve set up a profile here specifically because people should know what they’re getting themselves into, so please don’t take this as bragging. I have one of the largest cocks around, and anyone who hopes to get close with me ought to be aware of that. If you saw my bulge and thought that was me showing off, that is not an erection - it’s actually the smallest I am these days. My ideal partner is a woman with a curvy figure and eager to partake of my endowment as much as she can. I know I am too thick for oral and must take care for vaginal, but I am a patient and practiced lover, so I assure you if you’ve ever wondered if you can take more, I can help you find your limit.

I have been diagnosed with macrogenitosomia and hyperspermia, so I hope you enjoy massive amounts of cum along with my extreme size. Cannot use condoms safely, so please have other forms of birth control in use. I can provide STD screening results on demand. My libido matches the rest of me there, so please let me know if you are insatiable for other partners in case I try to hold back by default.

Personal Pictures:

[Unlike his front-facing photos, these are very to the point. The first shows him in a pair of boxer shorts, his firm thighs and thigh abdomen almost lost to the edges of the shot to show his soft cock and balls’ bulges in them, the shaft in line with most porn performers, just curved to fit into the fabric. The next is even more blatant, a large four-panel collation of his bare, aroused prick on display in what appears to be an office. His cock was massive and turgid, a redder shade than the rest of his skin as its veins riddled the surface with their bendy protrusions. The fist-sized tip was peeled out. The first shot was with it laid on a table in profile, a ruler held over it as it jutted perpendicularly from his crotch, tufts of dark pubic hair at the base. The ruler rested right over his length and didn’t reach to the tip when aligned loosely to his groin. A second appeared to be the same position from above instead of the side, this time the ruler laid on his huge cock and two soda cans on their side alongside him, that monstrous organ thicker than either can and longer than them both together. The third had it off the table, his top lifted and a woman’s hand helping to hold his shaft up against his well-muscled abdomen, the tip nearly at the base of his rib cage with a thick stream of precum visibly running from the tip to the middle of his ball sack, those nearly-tennis-ball-sized behemoth lust orbs weighing down his skin. The final corner had his cock tip resting over a glass, cum dribbling from the shockingly wide slit into the base of the glass, filled nearly half way with thick, white-ish jizz.]

Out of Character:

Welcome back. The premise for the RP here is pretty straight forward. If you are feeling ambitious, you can post back with a profile of your character directly. Either that way or through a more direct OOC initial conversation, we can make any adjustments to the characters’ looks or whatnot to make something work. In particular, the specifics of Blake’s size are negotiable - he should have a nearly too huge cock or otherwise be noteworthy for how hung he is, but that can run a rather far gamut.

As in the profile, Blake can be set up for a one-time encounter for a wild romp with a size queen, or potentially something more romantic and substantial with a woman well aware of what intimacy with him will involve. As he suggests, Blake responds very positively to exceptional curves, a bit more of a tit fiend but appreciative of round rears as well, but that is not strictly necessary. The general idea here would be either to have some “in-app” chatting after the profile match, then moving that into a “real world” encounter, whether a date, casual meetup, or more directly sexual rendezvous.

I have some thoughts on Blake being either before the RP or, perhaps, after thanks to your character’s efforts, well known for his anatomical excess, being either a record setter or just a clear overly hung freak of nature with some notoriety (but not generally anything of a major star). Inquire within!

Posts can vary from a few sentences to a few paragraphs, typically matching my partner’s style, though I default to third-person and past or present tense. Chat or DM works for me - ideally we can take this to Discord if it goes longer-term, but that’s not required.
