The male (purple skin, white hair, horns, fangs) stands behind the female and presses her whole body against the tree trunk with his strong body.
The man's left hand roughly grabs the woman's left thigh/buttocks, while his right hand grabs the woman's right leg and lifts it high to form an extremely open posture, allowing the to penetrate deeper and more fiercely.
The woman's upper body is completely bent, her back is tightly pressed against the man's chest, and the chest (very full) is deformed due to the posture, hanging forward and downward and shaking violently, covered with sweat and body fluids.
Women are wearing clothes that have been pulled apart (white blue-edged uniforms, green bows still on), with their lower bodies completely exposed
The blue-haired female (who appears to be a character from Azur Lane or similar style, possibly a corporate or similar ship girl) is violently inserted from behind by a purple-skinned demon/orc male.
The woman's upper body is strongly tilted back, with her head almost touching the man's chest/shoulders, her face facing up, and her expression extremely high and absent-minded (eyes rolled up, saliva flowing out, tongue sticking out).
Her legs were forcibly lifted and separated by men, especially her right leg was greatly raised, almost at an extreme angle like a "straight horse", and her feet were grabbed or fixed on tree trunks/rocks by men.
