Test Subjects that you can sex without having machines holding them, the players can fuck them in a few different positions (ex: bent over, standing, agaisnt wall, etc.) and the Test Subjects can also fuck the player as well if they have a penis.

Wether it's the player fucking the Test Subject or the Test Subject fucking the player, both ways could count with the same positions.

So at this point, all we have are happy subjects, and there's nothing wrong with that but what about chicks that show that everybody's got a little canine in 'em when they cum? (All links are NSFW, BTW)

<--Either howling or panting

Or what about the guys that clench their teeth? https://e621.net/post/show/1008467/anthro-armpits-balls-canine-clenched_teeth-coyote That's hot. Just sayin; there's room for tons more facial expressions above and beyond just pleasure and grimacing.

ever wanted to try out something different from the traditional body-holding rack, but that still works to keep the subject restrained or in an adecquate place for having fun?

well, here's my few ideas for different rack models:

-Padded ErgoRack: a Rack that's designed with soft silicone pads in order to give the subjects more comfort, and slightly increasing the effectiveness of sexual interactions in a %12...while decreasing the effectiveness of vibrating toys on a %10

-HoveRack: a very sophisticated type of Rack that uses state of the art Gravitational Technologies for holding the subject in the air without causing any bodily discomforts to it, and increasing the effectiveness of all types of stimulation by %30 thanks to the nullification of any discomfort interfering with the brain's pleasure signals...however, Feline or Nerveous Subjects may find this kind of rack EXTREMELY discomfortable (all sexual stats go to negative until being placed into a different type of rack)

-BC Rack: (BC stands for Body Controlling) is a type of rack that removes any possible irritations to the body, by using special electrodes that instead direct the subject's poses as desired by the controller. this types of Racks have an extraordinary effect on submissive or masochist characters by increasing all stimulation types by %80........however, fearful or dominant characters may LOATHE this Rack, and instead...this could cause either an inmediate loss of the mission, or a potential sue to the operator.

-Tentaculoid Rack: Straight from a Japanese Manufacturer, Designed with the best hydraulics, and smoothest synthetic skins for the tentacles...this Rack, can hold subjects in various positions, or even provide some stimulation by controlling the tentacles to rather hold into...other parts. this type of rack can easily trigger orgasms no matter the sexual orientation or dislikes the subject may have, thanks to the extremely efficient A.I. Controlling the Tentaculoid, thus making each tentacle perfectly capable of finding out sensitive spots and knowing how to stimulate them to the maximum %30 / %120 depending on the subject's acceptance of the Tentaculoid.

-Hired Rack-man/Rack-woman: ...this is what happens, when the subject would rather like having someone holding it. this type of rack, is LITERALLY...a subject or assistant holding the body of the one subject intended for sexual purposes. depending on the affinity the subject may feel for the holder, or the way the holder is holding the subject, the effectiveness of the methods may vary from between %250+, to %50-.

-Reflective Rack: This type of Rack has been designed with the most efficient technologies for deflecting vibrations back to their source or to even reduce roughness of things pushing anything tied to this Rack. Vibratory Stimulations's effectiveness increases to %200+...while sexual stimulation may either be completely nullified (soft mating)...or granted the ability to trully stimulate its target (rough mating may be softened enought for a delicate subject to enjoy this)

-Thermo Rack: This type of Rack has an incorporated Thermal Regulation mechanism, for an easy control to increase temperatures (effective for relaxing newcoming subjects)...or to cool down heavily aroused/overstimulated characters (effective for increasing the subject's tolerance of stimulations or orgasm denials).

-Controrgasm Mk1: a type of rack, that's not so easy to come by...but it's certainly worthy of buying, as it's got an incorporated orgasm-stopper mechanism, which can prevent any subjects from being accidentally orgasmed while being edged by the operator. the way this Rack works, is by shutting down any toys which are being used if the subject is dangerously close to orgasm, or using a gravitational hold to keep genitals or fingers from moving and causing additional stimulation to the subject if said stimulation can trigger an orgasm. this Rack does not prevent the operator from still stimulating the subject, but does prevent "sloppy errors" by holding the operator or its toys until the subject has an acceptable margin of stimulable levels.

-Controrgasm Mk2: Only available when you're in good terms with a CEO of the company producing the Mk1. this type of Rack, unlike the previous one which limited you to basic edging without slipping....allows you to actually overstimulate the subject beyond what would logically be the Orgasm-Triggering Point.....HOWEVER, no orgasms can be archieved at all regardless of how extreme the stimulation may be, because this Rack counts with specialized electro-chemical control over the womb/prostate of the subject to prevent any orgasms from being triggered, while allowing for extreme stimulation levels to be applied to the subject. this Rack is extraordinarily effective at aiding in the production of sterile lube (heavy precum harvest in males...heavily dripping fluids in females) or keeping edge-loving subjects on a total ecstasy.

...even with contacts, this Rack is not the slightest cheap...thought it is certainly much easier to purchase than the DeuSubliMaximus...as you can get it mid-game if you play your cards right.

-DeuSubliMaximus: the ULTIMATE Type of Rack. one that's capable of controlling every single aspect of the subject, from things as simple as producing tickling stimulation without a single touch being applied to the subject, and up to keeping a perpetual state of climax on the subject...all under control of sliders and without a single flawl......except...perhaps.....for the fact that this rack is so ridiculously expensive that you'd need to complete a ton of tasks and become quite frugal about your money in order to get a chance to buy one (and THAT, with the aid of some contacts which may help to negociate an acceptable price for you). the other potential flawl, would be, that for anyone working with these......the job can become quite boring after using it for some time....so it is only advised for workers to use it every once in a while....perhaps with difficult clients...or when you just want to experiment a little.

Given the Inventory UI, you are already likely to include more clothes options. I just wanted to formally suggest various types of underwear, maybe with the option to have sex with them opened/pulled down instead of removing them (as pants currently are)

Alternative vagina styles, beyond labia length and clit size. Could include cloaca, labia type, anthro looks (equine, canine) and vaginas hidden under plates that swell out when aroused for the scalies.

Vaginas are a lot more varied than a lot of porn games show so it'd be nice to see options.

This suggestion is for both male and female characters to have anal contractions while having an orgasm. Anal contractions could result from other stimuli too, though I don't have any ideas on that front. That I found "visual documentation" (porn) didn't surprise me. Much to my surprise looking up the topic I found medical documentation on anal contractions. For science... literally!

On males:
www.ncbi.nlm.nih.gov

Pelvic muscle contractions during sexual response can be monitored conveniently by the anal probe method described. Eleven young adult male subjects were each recorded for three sessions of masturbation to orgasm. Electrical signals from an anal pressure probe were automatically digitized by computer. Orgasmic contractions were easily distinguished from voluntary contractions by the steadily increasing intervals and complete muscle relaxation between orgasmic contractions. At orgasm each subject produced a characteristic series of contractions starting abruptly at an intercontraction interval of about 0.6 seconds, and continued for 10 to 15 contractions at an increasing increment of about 0.1 second per contraction. Pressure amplitude, representing the force of contractions, increased from the beginning of the regular series to a maximum at the seventh or eighth contraction. Area under the pressure curve, reflecting muscular exertion during contraction, generally increased throughout the regular series. Each man's pattern of contractions was very similar from one session to the next and distinguished his records from others'. Individuals' patterns could be grouped into three types, based chiefly on the location of the regular contraction series within the subjective span of orgasm. The most common type was a simple series of regular contractions. It had the shortest duration and fewest contractions. The next most common pattern began with the regular series, followed by a number of irregular contractions. This type was longest in duration. One man with a third type of intermediate duration, had a number of preliminary contractions before the series of regular contractions began in midorgasm.

On females:

http://link.springer.com/article/10.1007%2FBF01541

Eleven nulliparous women manually self-stimulated to orgasm, each on three separate occasions. Pelvic contraction pressure was measured by an anal probe and a vaginal probe simultaneously. Near the perceived start of orgasm, a series of regular contractions began in nine of the women. Anal and vaginal contraction waveforms were synchronized with each other, and the same number of orgasmic contractions occurred in each lumen. Anal pressure had a higher resting baseline and greater amplitude contractions than vaginal pressure. The perceived start of orgasm did not correspond precisely with the onset of regular contractions. Mean intercontraction intervals increased linearly at an increment of about 0.1 second through the series of regular contractions. Amplitudes of contraction pressure waveforms, representing pelvic muscular force, were initially low, increased through the first half of the regular series, and then decreased. Area and net area of the pressure waveforms, reflecting pelvic muscular exertion (force × time), increased during the regular orgasmic contractions. Three of the women's orgasms consistently included only a series of regular contractions (orgasm type I). For six other women, orgasms consistently continued beyond the regular series with additional irregular contractions (orgasm type II). Types I and II had been identified previously in men. Two women had no regular contractions during reported orgasms. This pattern, type IV, had not been recorded in men. Women of different types showed marked differences in orgasm duration and number of contractions. Identification of these types in subjects is important for meaningful comparison of contraction parameters in different studies.

It can be difficult to see the action up close with that great big fuzzy thing obscuring the view. Either it should move out of the way, relative to the species, or become transparent.

Have a room where you set up a subject with your favorite stuff happening to them ... for days. I would suggest keeping it from being too terribly dark; they can leave whenever, but they are incentivized to stay with a bonus for each day they remain. In gameplay terms, it'd just be a place where you can easily just go see your favorite porn, live, basically.

So, I find it very wierd that fek has not implemented voice-acted characters in the game yet. I hope Fek adds voice-acted subjects in the game soon to increase the immersion, especially in VR
