Nila wants to with you a VERY Happy Valentine's Day

(Special alts available to my Patrons!)
Night Elf Nila lays suggestively on her back. Her entire body, save for her head, is encased in skin-tight black latex. With one hand, she plays with her null bulge, labeled with a pink lock symbol. With her other hand, she brings a finger to her parted lips and looks coquettishly at the view. The shattered moon symbol that usually adorns her head is replaced with a pink heart. The word "HOLE" is written in pink behind her.

Looks like Senat made the team, but maybe not in the way he expected.

(High quality versions, textless versions, and a cock-out alt available to my Patrons! www.patreon.com/c/PrototypeS...)
Senat lays on his back on a locker room bench, tied down with a jump rope. He wears his soccer uniform, but the jersy is tied at the bottom to expose his tummy. The fat coach straddles the bench and is sitting down so that his cock, covered in a stained jock strap, is pressed over Senat's face. Senat struggles, but can't escape as the coach demans he start licking, otherwise he'll just sit on the Anubian until he passes out.

Senat might not be the most athletically-inclined boy out there, but I'm sure Coach can find a place for him on the team.

(High quality versions, textless versions, and full cock-out alts available to my Patrons! www.patreon.com/c/PrototypeS...)
Senat, wearing dolphin shorts, a soccer jersey, and soccer cleats, kneels on the floor of a locker room. He's making twin peace signs, posing for a camera. He looks a bit confused and annoyed, as Coach (a large-bellied man with a cigarette) pulls his head in clsoe to the large bulge in his gym shorts. Senat says "Coach, I dunno...This feels like a weird pose for a yearbook photo...Are you SURE this is part of the varsity tryouts?"

Looks like Senat has finally started to fit in. Good for him.

#ZZZ #NSFWart
Senat lays back on a large, wooden desk. He wears a blindfold and a ring gag. His tongue is pulled out by a piercing that is connected to his nipple rings. He wears a skimpy maid outfit. His hands are tied behind his back and his legs are tied back and apart, exposing his ass. He wears a metal chastity cage. His asshole is gaping and splattered with a ton of cum. Von Lycaon has his back turned towards Senat and he is pulling his pants up, his big cock dripping with cum.

That attitude adjsutment seems to be workign quite well. Only 4995 hours of community maid service left for Senat. #vonlycaon #ZZZNSFW
Senat, dressed in a skimpy maid outfit, is shibari-hogtied face down in the foreground. A used jockstrap, with a tag reading "HOT SWEAT" on it, is half-draped over his face. Overwhelmed by the sweaty musk, Senat licks at the inside of the jockstrap. In the background, Von Lycoan stands naked next to a punching bag. He is wiping his armpit with a sweat rag. His cock, complete with Jacob's Ladder and Prince Albert piercings, hang half-flaccid. Dailogue balloons from Von Lycaon read: "A proper maid will always accomplish their duties, no matter how incapacitated they may be. If they can't use their hands, they will use their legs. If they can't use their legs, they'll use their mouths. Now, if my dirty clothes aren't properly tongue-cleaned by the time I'm finished showering, you'll spend the night in the sweat rag hamper with your mouth stuffed full of jockstraps. Have I made myself crystal clear?"

I don't play ZZZ, but Von Lycaon could spit on me and then turn me inside out like a gym sock and I'd thank him for the experience.
Von Lycaon, from the game Zenless Zone Zero, stands behind Senat, looking down at the Anubian boy with disdain as he checks his pocketwatch. He says "Your sentence of "Community Service" begins now. Consider yourself fortunate it is only for 5000 hours." Von Lycaon has a very noticeable bulge in his pants. Senat stands in front of him in an EXTREMELY skimpy 'maid' outfit, including a tiny skirt, thigh-high stockings and garters, stiletto heels, and a top that exposes his chest. He wears heart-shaped pasties over his nipples and a pair of handcuffs dangle from one of his wrists. He says "Seriously? What kind of sick freak came up with this "uniform", anyway? The least you could do is finish taking the cuffs off, you mangy perv. There are two, smaller panels. The top one is an upskirt shot of Senat, revealing that his skimpy thong is actually held in place by a buttplug. The lower panel shows a see-thru of the front of his thong, revealing he is locked in a tiny, metal chastity cage.

I am currently hyperfixated on my gay little jackal twink, so I’m sorry if you don’t like drawings of boys with waists that just beg to be gripped until you leave marks. It will happen again. Apologies. 🥺

Looks like Zara got on the boss's bad side somehow. And just because she's heavily augmented with biotek doesn't mean she's gonna be able to bust through some good ol' heavy metal bondage. Follow-up pics available to patrons

#bondage #nsfwart #NightsGarden
Zara lies on a low table. Her body is bolted and chained down to the table by several, thick, heavy chains and padlocks, as well as manacles held in place by large bolts. A box is bolted in place around her head and she looks up nervously at a woman. The woman holds a cigarette in her fingers, while a man stands just off-screen. Beside the table Zara is chained to are small trays. A whip, a stun gun, a Wartenburg wheel, and a half-filled ashtray sit on the trays, as if waiting to be used.

It always seems like something is missing. And this time it was fixed.
Сold metal touched and pierced most sensitive parts of the body to become as reminder...

Malakai seems to have ended up on the wrong side of some sci-fi villain and gotten himself 'contained'. At least they were kind enough to give him some 'stimulation'.

#breathplay #vacbed #bondage
Malakai, a draconian, hangs upside down in a sci-fi looking laboratory. He is naked and tightly vacuum-sealed in a translucent, latex sack. Tentacles snake down into the sack and slither around his body, groping his nipple and wrapping aroudn his face. He glares angrily at the viewer, a thick, airtight muzzle pulled over his face. The muzzle is connected to a rubber rebreather bag, forcing him to take shallow, careful breaths. His penis protrudes out of the vac-sack and is being milked by a vubrating sleeve and he is cumming hard despite the situation.
