Jess had known Katie since she was a baby. 5 years her senior, Jess had many fond memories of play dates with the Taylor family growing up.
Now 18 years old, Katie was not the girl that she had grown up with. After Mrs Taylor had died unexpectedly, Mr Taylor had become very protective of her. She was pulled out of school and taught at home, and her Dad strictly regulated the movies and TV she was allowed to watch. Relationships were completely out of the question.
That was how Jess found herself ""babysitting"" Katie when Mr Taylor went away on business trips.
"Help yourself to anything in the fridge. And remember, only the kids movies on Netflix and lights out by 10pm." Mr Taylor said, fussing over his last few bits of packing.
"Got it." Jess said, adding "We're going to have a great time. Aren't we Kay?"
Katie nodded excitedly. Jess knew she was Katie's only real friend, a result of Mr Taylor's overwhelming parenting style. She enjoyed their evenings together, watching movies and dancing to music; giving Katie the chance to experience something of a normal friendship.
"I should be back by midday tomorrow. Please let me know if you have any issues."
"You have nothing to worry about Mr T."

Later that evening, the girls' stomachs were full, and they were cuddled up on the sofa, a blanket pulled over them.
Jess enjoyed the easy affection they had always shared, but as they had become older things had become...complicated. Katie was gorgeous - all soft curves and plump lips - and Jess' body made her attraction to the girl known. Her pussy would get wet when they were cuddling, and she often had to excuse herself to the bathroom to sort herself out.
Tonight was no exception, and Jess moved away from Katie's embrace, trying to repress the heat that was fast building in her lower abdomen.
"We have a few hours before bed. What would you like to do? We could watch a movie?" Jess suggested.
"I've watched all of the movies on my Netflix 100 times." Katie groaned. There were very few movies Mr Taylor had deemed as 'suitable', and they had indeed watched them many times.
"Okay. What would you like to do?" Jess asked.
"Hmmm." Katie mused. "Ooh, I know! I can show you the new clothes that I got!" She jumped up from the sofa.
"I would love that!" Jess enthused.
A mini fashion show started, with Katie bounding down the stairs in an array of different outfits. Jess laughed as Katie pulled cheesy supermodel poses.
"Last one." Katie said, and Jess couldn't help but notice a blush spreading over her cheeks as she went upstairs to change into the last outfit.
The reason for this became clear when a few minutes later, Katie came downstairs wearing only a lace bra and panties.
Jess' jaw dropped. "Where did you get those from, Kay?" Jess asked, knowing Mr Taylor would certainly not approve of this particular ensemble.
"The lady got me to try them on when she was fitting me for a bra. Aren't they really pretty?" Katie said, twirling to show them off.
Jess might have been her pseudo-babysitter, but she was still a warm-blooded woman. The lace two-piece perfectly highlighted her soft curves. Her cleavage plunged down between her pert breasts. The lace of the panties barely covered her ass cheeks. As Katie sat down on the sofa beside her, she could make out the shape of her lips through the thin fabric of the panties. Jess gulped.
"Do you not like them?" Katie asked, sensing her tension. She moved closer to her on the sofa, her bare leg resting against Jess' clothed one.
"No, no, I love them. Um. They're really pretty." Jess said.
"I knew you'd like them." Katie grinned, climbing onto her lap to hug her closely. And oh god, she could feel the warmth of her pussy resting against her thigh.
Then, before Jess could think of an excuse to get out of this particular predicament, Katie started giggling.
"What's funny?" Jess asked.
"It's just this thing that sometimes happens when I'm around you." Katie said. "My kitty gets all wet."
Jess gasped, and Katie looked scared by her expression. "Oh no, is there something wrong with me?" Jess shook her head, but she must have looked extremely frazzled, as Katie turned bright red, climbing off her lap and turning away from her. "Oh god, I shouldn't have said anything."
"No, no! There's nothing wrong with you." Jess reassured, grabbing her wrist. "Hey, look at me. It's completely natural."
"Really?"
Jess knew she was completely overstepping the boundaries set by Mr Taylor now, but Katie couldn't keep thinking something was wrong with her every time she got turned on. She had to know that it was all normal.
"When your...your kitty gets wet it's because it wants to be touched." Jess explained. "Because you're attracted to someone. Sexually attracted."
"Oh." Katie's eyes were wide, but with excitement not fear. She looked exhilarated by this new information. "Sex. It's like kissing but more, right?"
"Yeah, kind of like that." Jess replied. "People do it to show that they love each other."
"I love you." Katie said, earnestly.
"I love you too." Jess said, linking their fingers together. And it was true. She and Katie had always had a special connection growing up. And seeing her blossom in front of her eyes into a beautiful woman had been incredible.
"Jess. What - what is kissing like?" Katie asked, blushing furiously.
"Do you want me to show you?"
"Please."
Jess leaned forward and pressed her lips to Katie's in a soft peck.
"Mmmm I like that." Katie said, smiling giddily.
"I like it too." Jess said.
They sat there smiling at each other for a moment, playing with each other's fingers where they were linked between them.
"I want - " She seemed to be unable to finish her sentence, lacking words for what she wanted. Jess knew it was inappropriate and completely overstepping the boundaries, but she also knew that Katie had no idea how to make herself feel good. Katie didn't have the words for it, but she wanted to be touched.
Jess leaned in and pressed her lips to the other girl's more firmly now, experimentally opening her mouth to deepen the kiss. Katie gasped, kissing back eagerly. Jess nipped her bottom lip, brushing their tongues together. When she pulled back, a flush had spread across the younger girl's cheeks and neck.
"Do you want more?" Jess asked, checking in. Katie nodded in reply.
Jess brushed her lips over Katie's, before mouthing along her jaw and down her neck. Katie gasped as Jess licked and sucked the sensitive spot under her ear. Continuing her journey, she mouthed along her collarbone, sucking hard and leaning back to admire the mark she left.
"Can I take this off?" Jess asked, hands reaching around to the strap of her bra.
