--Viper and Sectoid--
With the vast number of xenos composing ADVENT, it's no surprise that there are occasional cases of aggression or infighting between different species. Since the majority of the Sectoid population's genes were mixed with human DNA, this aggressive nature has had a notable impact in these feuds between aliens. It is not uncommon to see these tensions released on the battlefield in the form of sexual assault, with the female Vipers and female human ADVENT troops as the sectoid's victims. This footage from an apartment raid under suspicion of XCOM activity shows such aggression.
Using their psionic powers, the sectoids control their squad Viper, leaving her grasping to life after a near fatal charge towards the XCOM soldiers. With the rebels dealt with and the clean up crew hours away, the sectoids enjoy their fallen squadmate's soon to be corpse. The youngest sectoid pureblood jumps the body first, slamming it's cock down the fatal gunshot in the base of her neck. The reptilian xeno gasped for air, blood filling her lungs and an alien dick penetrating her esophagus.
The sectoid hybrid alpha was next to pounce. Removing the plating covering the base of her tail, her divided muscles resembled that of a human female's rear and hips. The sectoid made no hesitation thrusting into her ovaries as his limbs wrapped around her twitching tail. The other pureblood removed her breast armor plating. Through human DNA testing, most female vipers developed breasts, the fat and shape combined with her lung sacs. The scaly creature's skin was soft around this region, feeling identical to a human breast; firmer, but more prone to damage. Without any effort the pureblood pierced her breast, and in doing so, her lungs as well. The sectoid's pelvis pressed the breast against her, the alien holding her weakened arm down easily with his foot.
The viper opened it's maw in an attempt to scream in pain, only a sharp whistling escaping her lungs as the purebloods' cocks fucked her airway. Tired from the blood loss and lack of oxygen, the second hybrid sectoid spread open her normally powerful jaws. She gagged weakly as the cock pierced her throat, her saliva and blood gushing up from her lungs drenched his penis in warmth. Gripping the sides of her jaws, he yanked her dying head back and forth, small final gasps for air escaping before her eyes rolled upwards. The powerful muscles in her throat tightened as she finally succumbed to the suffocation.

Blood was sadly the best particles I have. Lighting never works properly with it.

It's a different idea, definitely under consideration.

Skinning would be REALLY hard to animate, plus I don't have any skinless/muscle girl models.
