Commander Shepard sits on the edge of a plush sofa in a club, scantily dressed in black lingerie with a collar and leather harness. He's muscular, with a tiny waist, thigh thighs, and huge breasts barely contained by a black bra while he reaches both hands up to rest them on his head. His muscular legs are spread wide, exposing his bare pussy and pierced clit to the viewer.

Still barely dressed, Shepard sits on a stool, turned almost to the side to show off just how narrow his waist is in comparison to the width of his shapely hips and big tits.

Shepard stands on his knees, flanked by a standing human man and an asari, both who have their large dicks out and draped over his bare tits, obviously eager for him to blow them.

The asari holds Shepard up effortlessly in what is almost a full nelson, their hands locked behind his knees instead of his head. Shepards big, heavy tits are squished together obscenely in this position, his pussy fully exposed as the asari plows it roughly with their massive cock.

In the interest of inter-species cooperation, Commander Shepard has been assigned a new sort of mission to help diplomatic efforts between the Alliance and the Asari along.
After being resurrected by Cerberus, the Commander is now able to change his body's physiology at will-

Same as before but the orc adventurer is now heavily pregnant with large breasts gushing milk as he is filled with another load of his captor's seed.

Request from a supporter who wanted an orc adventurer getting captured bred by an even larger, more dominant orc! You know he's gonna be putting some absolutely enormous babies in him 😮‍💨

A gorgeous, femboy incubus with a slim build but wide, child bearing hips stands offering you a pomegranate. His skin is pearlescent white and scaled while he has large, dark wings and a slender tail wearing a great deal of gold jewelry and sheer black silk.

The incubus stands imperiously before a pair of larger, but subservient demons that bow to him. He is mostly naked with his enormous pink cock on display, body illuminated by candles and moonlight.

One of the large demons looms behind the fully nude incubus now with a leer on its face, it's monstrous cock jutting out from between the inucubus' thighs. The incubus appears delighted by this turn of events, his own cock replaced by a glistening pussy ready to be bred.

Malachi the incubus serves in his master Caerophon's bed faithfully, but when the demon lord is gone too long on campaign the incubus must sate his hungers elsewhere. They always need more -

A large orc is strung up by his neck and ass, ready to be fucked by the heavily scaled basilisk man behind him. The orc's arms and legs are missing and his upper half is petrified, as are the stumps of his legs, leaving him totally at the basilisk's mercy while it pumps his increasingly swollen gut full of eggs.

Zach's transformation continues and he seems aroused rather than afraid now as he leans back on the pedestal, legs spread to expose a new pussy set below his balls. His cock has darkened significantly and is shaped like a horse's rather than a human's, now. His four breasts have increased in number again to six, all with large, stiff nipples aching to be sucked.

A scantily clad king struggles, impaled on Eros's impossibly massive cock while the god grips him tight by the neck and arm. The god's cock is so big it forces the king's entire abdomen to bulge obscenely outwards and yet he still hasn't taken it fully to the base.

A king with a barren wife prayed too hard for an heir and Eros arrived to grant the man's wish in person. Rather than wasting time making the Queen fertile, however, the god worked his magic on the King instead and planted a demi-god princeling in his belly for his devotion.
