Final Fantasy VII, Aeris/Zack/Cloud/Sephiroth, pregnancy!sex (or fetishization of a pregnant body)
It was hard to resist her.
Wasn't like any of them tried very hard.
One of the first thing Sephiroth did every morning when he woke up was to touch her, his fingers running over her cheeks, her throat, the line of her shoulders. Carefully over her breasts, especially after the one time she scowled at him for poking too hard.
Along the still growing curve of her stomach. That part got the most attention. Fingertips first, then his palm, resting there, feeling the life in her belly growing.
If she had woken up by that time, his fingers would continue to pet her belly and he would shift to use his mouth even lower, a strange apology for disturbing her. She couldn't get him to stop, not that she really minded, and she'd end up laying on the bed, panting and very, very relaxed, and he'd ghost out of the room to attend to whatever had him up so early.
Cloud was next. He was always up just after Seph was, and he always gave her a small smile, offering up a kiss and asking what she wanted for breakfast. His fingers would also rest on her belly, and she knew he was in special awe of the situation. Zack and Seph couldn't have kids, it turned out, not with the changes in their genetics. So Cloud, who was the type to be obsessively protective anyway, was in high gear all the time.
No wonder Aeris always felt the needs to pounce him.
After Cloud would wobble off, eyes slightly dazed and the smile larger on his face as he went to fix Aeris her breakfast, she'd always find herself pulled back against Zack.
"Do you know how sexy that is?" he purred into her ear every morning, one arm curled around just under her breasts, her back against his chest.
"You always looked good, but now when you are on him, you curl back, and this makes such an interesting addition to the view." His free hand slid down over her stomach, fingers tracing almost the exact same path that Seph had earlier.
"I keep waiting for you to tell us to back off, or to stop obsessing, but you never do."
The words were whispered along the side of her neck, Zack's lips barely touching her skin and sending shivers down her spine. "You smell so good, fresh and bright. Like your flowers. I just want to lick your skin, taste all that scent." A lap up the nape of her neck, and he rubbed against her.
His fingers continued to pet, to tease, running up and down her belly, along the underside, where it was surprisingly sensitive, and up where what had been her belly button stuck out.
"None of us can get enough of you. You're even more beautiful than you were before."
His fingers slid further down, and she'd sigh out a noise at the touch, eyes shutting as she did. He'd keep it up, rubbing against her, lips brushing over the back of her neck and her shoulders, breathing words of praise as he kept up his actions.
After both of them had shivered to completion, he'd collect her for a quick shower, the timing perfect for them to come back to a clean bed and Cloud there with breakfast.
