Ann did join them in the water eventually, and Shego went back and forth between redheads, kissing her several times in her post-coital buzz. After some actual swimming, they all went in for a lunch of cold roast beef sandwiches and fruit juice before, oceanic orgasms aside, they repeated the whole process for the afternoon.
For dinner they decided on chicken with rice and fried onions, and Kim watched as the other two spent an hour cooking it all up, wearing aprons just in case. They took their meal outside, along with a plate of watermelon slices, and enjoyed the view as they ate everything. When Kim's mouth overflowed with the juice of the chilled fruit, Shego was quick to lick her chin clean. Licking progressed to kissing. Ann briefly considered having a similiar 'accident' but instead suggested they go shower before they got too distracted.
Ann cleaned the kitchen up a bit while the girls shared the shower. After she watched them stumble into their bedroom, Shego carrying Kim who was wrapped tightly around her, she took her turn washing the sand and salt off her body and out of her hair. She found herself wondering what it would be like to share a shower with Shego, hands roaming across wet skin, mouths sucking, teeth nipping, tongues tasting. Perhaps, in the shower back home... perhaps with James watching?
Of course, thinking and doing were two different things. But it was definitely something to think about.
Things were surprisingly quiet when Ann went to her bedroom, but it didn't last for long. At first, she continued to read her book, since the soundtrack coming through the wall was appropriate for the material. As the volume increased, she began to tell whose voice was whose. Whatever Kim was doing, Shego was certainly enjoying it.
It took Ann a while to remember that she could probably go and look, and they wouldn't mind in the least. It made her smile; the fact that it hadn't immediately occured to her meant the villainess hadn't completely corrupted her yet. Nevertheless, she put the book down, settled more comfortably into bed and started teasing her bare skin with her fingertips. As she did, Shego's voice growled words Ann couldn't quite hear between her less composed exclamations, but it was clear she was encouraging Kim's current efforts.
The elder Possible's mind began to wander, imagining what she could do to provoke such a response. Her hands began to focus on her breasts, the nipples already hardened by what she was listening to. When the green girl's voice clearly declared, "Eat that pussy! Eat that fuckin' pussy!" Ann wondered what it tasted like, how it would feel to have those thighs pressing against her ears, a hand in her hair, forcing her face harder against Shego's bare crotch.
Pinching her nipples hard as Shego climaxed noisily, Ann's breath hitched in delight. Oh yes, she could expand her horizons. That question had been answered definitively. She didn't have to do it to know it... but she wanted to. That's what she'd tell James. It would be safer for his feelings than actually going through with the experiment; the option would still be on the table, and being one step closer to the real thing might help him decide how he felt about it.
Kim's voice was picking up now. They were taking turns. Ann wondered why as she imagined herself in her daughter's position. Was Shego going down on her? Did they ever do that to each other at the same time? What might there be for two girls to do to each other that she didn't know about?
Hearing Kim come made Ann smile, but Shego's next turn had the neurosurgeon send a hand down between her legs to stroke at the increasingly wet lips there. As the girls repeated their cycle of gratification, Ann worked herself up a little more than the last time.
The next thing she knew, a couple of hours had passed; and she only noticed because the pause before Kim's next turn was long enough for her to glance at her watch on the bedside table. Had they tired themselves out or were they gearing up for a big finish?
The big finish theory proved correct when the girls' bed started banging against the wall. Their voices followed, Kim's inarticulate noises resolving into repeated use of the words "Fuck!" and "Don't stop!" while Shego's growls became...
Ann couldn't believe what she was hearing, let alone how Kimmie was responding to it. Her daughter was practically screaming when she lost the ability to form words entirely. Ann waited until the climax was well and truly over, then stated in a loud voice that was sure to penetrate the wall, "My daughter is not a dirty little slut!"
"Not a slut," Shego yelled back breathlessly, "My slut!"
This prompted some near-hysterical giggling from Kim. "Don't worry mom, we already worked this out. I'm her slut, she's my whore!" She then yelped in response to a smack that was almost certainly applied to her ass.
"The hell I am, princess!"
In the short silence that followed, Ann could imagine Kim giving Shego her 'oh really' face; then she blinked in surprise when she heard her daughter say, "So if I offerred you money to fuck my mom's brains out, you wouldn't take it?"
Another brief silence. What was Shego's 'oh really' face, the non-plussed expression with the single raised eyebrow? "How much?" The green girl asked.
Ann heard the wicked grin in Kim's voice as she perfectly imitated her mother: "I'll give you five dollars."
If her voice hadn't caught in her throat, Ann would have voiced a complaint at Kimmie's cheek. As it was, all she could do was croak... and then Shego appeared in her doorway. The villainess was sweaty, her hair a complete mess, the strap-on she was wearing was still wet and the emerald eyes that took in the sight of the elder Possible were hungry.
"I am such a whore," Shego drawled as she sauntered over to the bed. Ann could only stare as the young woman drank in the sight of her. "Hmm, looks like you've been doing some of my work for me. Perhaps I should skip the foreplay..." To her surprise, Ann all but launched herself upright, grabbing her and and pulling her down into a frantic kiss.
"Don't you dare," Ann gasped when she broke for breath.
Shego barely had time to adjust her rubber accessory as the older woman pulled her down on top of her. Then they were making out as if they'd never get another chance. Tongues played, hands groped, bodies rubbed, and voices groaned.
Ann grabbed Shego's ass with both hands and pulled upward, forcing the other pair of pale green mounds into view. The hands quickly slid up and around to grasp them and squeeze, then around her back to bring them into range of her mouth. Shego gasped and cursed as the doctor caught each nipple in turn between lip and teeth before twirling her tongue around the sore nub, and finally sucking as much of the surrounding flesh into her mouth as she could.
It didn't take long for the green girl to reciprocate, but when she started going lower, Ann remembered something. "What about Kimmie?"
Shego paused, her chin in Ann's bellybutton as she smirked up at her. "Don't worry, she'll be along..." the smirk went up a notch, "As soon as she can walk again. I'll just keep you as wet as you can be, until she shows up." She didn't specify whether she meant for Kim to watch or join in. It was a tease, and Ann knew it.
"You villain," she rebuked with a smile, then pulled Shego's chuckling face back to her stomach. The licks and noisy kisses continued all the way down to her thighs, and the further inward they went, the more Ann's legs spread to reveal what lay between. Shego bit gently at the tendons on either side before running her tongue up the entire length of Ann's labia, then gave the clit a sucking kiss with an appreciative groan on top.
Apparently it was Ann's response that made Kim find her legs again, for not long after, she was watching from the doorway. Ann glanced toward the movement, then looked again in amazement.
Kim was in no less disheveled a state as Shego when she had first appeared, except she was wearing a midnight blue dress with bare shoulders and a slit so far up the right side it seemed to reach her waist. She only had her right shoe on, and it made her leg peek out of the slit in a very sexy way.
"I know, right?" came a voice from the vicinity of Ann's crotch.
Ann was momentarily distracted by Kim's skin. At first glance it looked like a mild sunburn, but a more attentive stare proved otherwise. My goodness... is her entire body flushed? The realisation was immediately followed by a sudden urge to lick the revealed thigh from the knee up, as far as the dress would allow. She blinked several times as her super-ego caught up to her id, then asked the most unexpected question of the night.
"You're not wearing that to the prom, are you?"
Shego choked and burst out laughing, while Kim had the decency to look sheepish as she responded. "No, mom. This is an undercover dress, not a school dress. I'll get something from Club Banana for the prom." She paused. "But you like it, right? Sexy?"
"Very," Ann admitted.
"You should see it move when she spins and flips," Shego added.
"Talky mouth is not a sucky mouth, Shego," Kim shot back.
"Yeth, mithdrith," the green girl replied as she curled her tongue around Ann's pronounced clit and resumed licking.
Ann wasn't sure for how long Shego went down on her, only that it was nearly torture, the way she kept bringing her to the brink only to slow down again. The experience left her in something of a haze that was only broken when the villainess started kissing her way back up her body. The older woman tasted herself in the kiss that followed.
"Well," Shego said huskily, "I don't think you could possibly get any wetter, do you?" Before Ann could answer, she yanked the neurosurgeon down the bed and pulled her legs into the air before teasing the focus of her attention with the length and tip of the rubber cock she was wearing. Again, she acted before Ann could form a response, sliding the strap-on's entire length into the woman, eyes sparkling as she watched her new lover's reaction.
Shego didn't fuck Ann as hard as she had Kim; whether it was an act of consideration or a lack of energy, only the green girl knew. It was obvious how much she loved the look on Ann's face as she looked up at her, because she couldn't tear her eyes away. It caused Ann to glance over at Kim again, but her daughter still seemed content to watch... which was all she was doing.
"Kimmie," Ann gasped, "I told you..."
"I don't need to," the teenager assured her. "Shego totally wiped me out. I'll probably be sore in the morning," she added with a giggle, "But I still want to see this."
Afterwards, Ann would always remember it as the statement that allowed her to let herself go.
She pulled Shego down against her, flesh to flesh. Rocked her hips to meet every thrust. Lost her hands in Shego's hair, slid them down her back and ass, feeling the muscles of that hot, hard, sweaty body at work. When her climax began, she felt teeth in her neck and cried out all the louder. She was still gasping for breath when Shego's tongue invaded her mouth, and she couldn't imagine a better way to lose consciousness... which she believed she almost did.
"Satisfied?" Shego asked with an exhausted smile. Ann could only nod in response, prompting a (slightly) more sedate kiss. "Then my work here is done," she declared with a small final thrust that made Ann quiver. The villainess looked to Kim and cheekily demanded, "Pay up, princess."
Once again, Kim's expression became bashful. "Uh, mom... can I borrow five dollars?"
