Ann comes over

Tracy opened the door with a pleasant smile. “Glad you could make it!” She said, welcoming her friend inside.

Ann walked in, eyeing her friend with some interest as she did so. She wasn’t sure, but Tracy looked a little as though she had gained weight since last she saw her. Not only that, but she was dressed in loose-fitting cotton shorts and a low-cut shirt, through which she could make out the woman’s nipples clearly poking. This was a little unusual for Tracy, who usually took the occasion to dress a bit more fancily. For her part, she was wearing a modest red and white sundress that ended at her knees. But the most unusual thing was the look in Tracy’s eyes; the usual frustrated glare had been replaced by a confident, downright excited brightness that made Ann uneasy.

After standing near the kitchen table and pouring themselves some glasses of pinot noir, Tracy invited Ann to take their seats and start the movie. The usual pleasantries turned to more in-depth conversation as Tracy pressed play.

“So, what’s this thing about anyway? Invasion of the Body Snatchers?” Ann asked, swirling her glass of wine.

“Pretty self-explanatory.” Tracy said, maintaining her almost predatory stare. “Aliens invade, assume human forms to infiltrate society.”

“Sounds kinda weird.” Ann responded.

Out of the corner of her eye, Tracy spotted what she’d been waiting for. Minutes before Ann walked up to her front door, she had assisted her gooey alien clone in hiding itself in a nearby closet, positioned behind the couch. She had carefully seated herself on the couch in a place where she could keep an eye on the door, and Ann could not. Now she could make out a bright green liquid slowly and silently oozing itself underneath the crack in the door. The possessed woman suppressed a giddy smile, and pretended she’d seen nothing.

“Are you and Jacob doing alright?” Tracy decided to ask, to buy time.

“Oh yeah, pretty good.” Ann said. “He’s had some time off recently. How about you and Ethan?”

“Wonderful, actually.” Tracy answered, seeing the green blob now out in the open. It was making its way to the couch with surprising speed. “He’s actually started fucking me again. I rode the shit out of him on this couch last night.” She gently pressed her hand to the cushion.

“That’s, uh… Good for you.” Ann shifted uncomfortably, crossing and recrossing her legs. Tracy was never one to be so blunt about her sex life. Ann had practically have to pry it out of her that she and Ethan were having ‘problems in the bedroom’. The brunette’s newfound explicit nature made her all the more surprised. She took a long gulp of her wine. Behind her, the slime made its way under her seat.

“That’s actually why I called.” Tracy grinned perversely, scooting just a little closer to Ann. “See, I need your help. I was going to keep things low-key, but Ethan’s cum sorta changed my plans a little. I—well, we—need to borrow you for a little bit.”

“W-we?” Ann stammered confusedly. With all of Tracy’s strangeness she had entirely stopped paying attention to the movie in front of her. That, and the green blob that was now rising up right in front of her legs.

“That’s right.” Tracy nodded. “Ann, could you maybe uh… move just a little?” She asked, pointing to the redhead’s thighs.

Ann made the mistake of moving her legs ever so slightly before she even looked at where Tracy was pointing. The very second she uncrossed her legs, exposing a spot between her thighs, the slime seized its chance. It surged forward between her smooth calves, smacking her pelvis with its first tendrils.

Ann’s eyes went wide in shock, seeing the gooey thing that was shooting to her lower section. “What the fuuuuUUUUUUUU!!!” She screamed as within a split-second the slime found its way around her panties. She wanted to close her legs almost immediately, but she soon found Tracy’s strong hands spreading them further apart.

The brunette looked on in delight. “This is so… hot!” She realized that Tracy’s body was immensely aroused by the sight of another human being possessed, her pussy wet with excitement. She wanted to help her clone seize this new body, but the temptation to start pleasing herself proved too great.

“Tra-tra-“ Ann half-moaned, half-stammered, her brain malfunctioning as the slime continued to flood into her cunt and somehow further into her body. Her supposed friend, who she had been attempting to call for help, removed her grip from Ann’s legs and instead sat back, thrusting one hand down into her own shorts to masturbate at the sight. The redhead tried to close her legs again now that she was free, but she found her legs no longer responded. They instead spread wider, defying her own desires.

Tracy fingered herself as she watched Ann begin to convulse slightly, losing all control of her own body. The slime in her was amazed at how sensitive this human body was, and how watching a possession in action filled it with pure arousal. The possessed girl buried her fingers in herself over and over again, feeling the juices coat the insides of her shorts. As the last of the clone disappeared under the hem of Ann’s dress, Tracy came hard. Both women’s eyes rolled back in their sockets, though Ann’s quickly began to flutter as the rest of her body shook ever so slightly.

The sound of heavy breathing echoed in the room for a few moments. Tracy came down from the high of her orgasm, withdrawing her fingers from her cunt coated in green. As she sucked on her slick digits, Ann stirred again.

“This body feels interesting.” The redhead said, running her hands through her hair and down to her breasts. She looked over to Tracy. “Taking her over was… fun.”

“I’ll say.” Tracy grinned, happy with the fruits of her labor. “I think this mission is gonna be a great time no matter who we take.”

Ann gave a sly smirk, as though she had a devious idea. “Say Tracy,” She began, leaning over and crawling her way towards her friend. “I saw you flicking the bean when that thing was sliding inside me.” She got close to Tracy, close enough so that they could feel one another’s breath on their faces. “Now that it’s taken over my sexy body, what do you say we make the Empire wait another couple hours?”
