Mary found herself hesitating as she watched Julie and Adriana embrace and kiss. God, it was so arousing, seeing them enjoying each other like that. She dragged herself away, knowing that she shouldn't stay, knowing that she'd only end up doing something she shouldn't.
Adriana and Julie continued to entwine and dance their tongues about each other.
"Damn, I thought she was going to stay for a second there," Julie said, as they broke apart.
"Me too. Of course, we don't have to go to bed yet," Adriana said to her, a glint in her eye.
"Of course not, feel like a skinny dip?"
"I feel like a lot more than that!" Adriana said.
"Well, let's just start there, it will clean me up for when you get to lick my pussy," Julie said, pulling her clothing off and then leaping into the pool.
Mary had only made it as far as the kitchen, figuring that she needed water before she went to bed in the state that she was in. When she heard the splash, she was drawn back to look, justifying to herself that she needed to be sure that it was a deliberate splash and not an accident.
As she stood in the doorway that led outside, she saw Adriana slowly peel her clothes off, standing on the side of the pool, swaying seductively, obviously for the audience of one, Julie who was in the water. She continued to watch as Adriana dove into the pool, over the top of Julie.
She knew that she should have left then, but when Adriana surfaced, the two girls kissed again and she found it too seductive, too arousing, to simply turn around and leave. Her fingers found their way between her legs and she was fingering her pussy as she watched her daughter and niece kissing. She found herself hesitating further, even when the girls stopped kissing and began swimming around. She realised what she was really waiting for was the chance to see Julie naked. She remembered what her sister Olivia had looked like when they were younger and wanted to see how Julie compared. Given the way she filled out her swimsuit, it was bound to be lovely.
She found herself thinking back to the very first time that she'd touched Oliva's breasts. They'd developed quicker than her own and in a curious bit of exploration had asked her what the felt like. Soon she'd had them in her hands, then her mouth. It had all rolled from there.
Her fingers continued to work on her clitoris and she was about to give it up and go find somewhere quiet to masturbate when Julie climbed out of the pool.
Mary's knees went weak as the goddess-like body of her niece emerged from the water. Droplets ran down her perfect skin, cascaded from her erect nipples. Nipples that capped what could quite possibly be the most beautiful breasts she'd seen. Her eyes couldn't' stop though. There was more to see, the curve of her hips that were fuller than her own daughter's. Her legs were beautiful, less muscular than Adriana, but gorgeously proportioned. And between her legs, she was bald. All Mary could tell from this distance was that there was no hair. She now really wanted to go out there and get a closer look.
Julie took a drink and then returned to the edge of the pool, sitting down with her legs dangling in the water. Adriana moved over to her and Julie spread her legs, pulling her feet from the water and splaying them either side of her to give Adriana clear access to her pleasure centre.
Adriana pulled on Julie's breasts and then ran her fingers over her wet nakedness before moving with her tongue to begin feasting upon her pussy.
Dave stood at the windowsill, looking down at what was occurring in the pool. He'd heard splashing and had awoken. He moved quietly to the window, not wanting to wake Olivia. He looked to see what was happening and saw Julie and Adriana swimming in the pool. He was about to get back into bed when he realised that the two girls weren't just swimming, but were kissing! He stood, mesmerised by the scene below him and then, as he watched, took his cock from the boxers he was wearing and started to stroke his rapidly hardening erection. When Julie sat on the edge and Adriana started to lick her, he started to daydream about going down and joining in.
He'd fucked Julie and Adriana had the sort of body that any red-blooded male would want a piece of. He'd watched her grow up into a stunning athlete and now was seeing her in a light he'd not even thought to dream about. He'd let John fuck Julie; he wondered whether Adriana would be willing to repay the family debt.
Mary thought back to Julie's goodnight kiss. She'd slipped her tongue in. And she'd seemed intent on Mary staying. Mary had had sex with Adriana and she too had slipped her tongue into her mother's mouth whilst saying goodnight. Did they really want her to join in?
Mary was so horny now that she was prepared to take the chance. She stepped quietly outside, pausing after a couple of paces, her fingers still stimulating herself. She got about half way before Julie heard her and turned her head.
Julie glanced at her aunt, pleased to see her standing there. Even more pleased to note the lust that was clearly scrawled across her face.
"Hi Aunt Mary, have you changed your mind about staying?" Prompting Adriana to stop what she was doing and glance past her cousin's body to where her mother had stopped, frozen.
"I ... I ..." Mary started, not knowing what to say, even though she had now acknowledged what she wanted.
Julie stood from the side of the pool and walked over to her aunt. Mary's eyes danced over Julie as she approached, marvelling in the perfection. Julie took her Aunt in her arms and slid her tongue across her lips, which parted, allowing her tongue in turn to dance within Julie's mouth.
As they stood kissing, Adriana climbed from the pool and Julie started to remove her Aunt's clothing. Adriana moved in behind her mother and helped Julie to discard her clothing.
Mary half turned between the two young girls and kissed one and then the other as they wrapped their arms around her, their naked bodies fused in a tight embrace. She felt the girls' hands on her back, caressing her buttocks, welcoming her to their illicit union.
"I want to eat you Aunt Mary, and I want you to eat me too," Julie announced while she was sharing a kiss with her daughter.
"I want that too," Mary admitted, her breath husky with desire. Julie broke apart from the three-way embrace and led her Aunt to a sun-lounge, now lit with a searing splash of light from the full moon that hung overhead, presiding over proceedings.
