Emily felt more pressure on her diaper and the front was ripped roughly until it flopped open between her legs. Some of the tapes were still attached to the front, others to the back. It was such an animalistic display of strength that Emily couldn’t help but feel even more submissive to this woman’s whims.

Davina’s mouth explored Emily’s upper body. Aside from more kisses she licked, sucked and even lightly bit Emily in places that made her moan. As she did that one of Davina’s arms was laying over Emily’s dick, her hand curling down and a finger probing her butt. Emily wriggled whenever the finger got particularly close to the centre and when she opened her legs a little more, she could feel Davina giggle despite her mouth being full of one of Emily’s breasts at the time.

“Amelia was right.” Davina said as she pulled her mouth away a few seconds later, “You are adorable when you moan.”

Emily didn’t know why anyone who was intimate with her seemed to want to embarrass her. Was there just something about her that made people feel that they needed to make her blush? Emily turned her head away; she was smiling even as her face reddened. She didn’t look back until she heard a bottle being opened and looked back to see the same lube Amelia had used before, it was being put on Davina’s fingers.

When Davina’s hand returned between Emily’s legs it was to insert a finger into her. Emily gasped and raised her hips as the babysitter teased her opening and then slowly pushed inside. As usual, it was slightly uncomfortable for Emily for a few seconds before her body grew used to the invasion, then the pleasure came on strong. Still, it was a little disappointing. Her straining tool wanted more direct stimulation, or at least something a little more than a finger on her prostate. Despite this, as soon as Emily’s pleasure button was found and circled Emily was bucking and clutching at the sheets.

“Wow, Amelia said you were sensitive but I didn’t expect it to be quite this much.” Davina seemed almost impressed, “Amelia must keep you locked up a lot, hmm?”

Emily nodded. She didn’t want to tell the beautiful woman with her a finger in her ass that since the cage had been locked on it had mostly only come off for cleaning. Emily knew she already looked totally pathetic, she didn’t want to make it even worse, she was still scared Davina might change her mind about all this if she realised just how useless Emily was.

Emily was teased and loosened up. She was pressing against the fingers but at the same time keen not to be selfish. She had learned a little of how to pleasure Amelia and she wanted to do the same for Davina. However, every time Emily reached to try for Davina, she pulled away a little and smiled.

“All in good time.” Davina said. She pulled out some baby wipes and started gently cleaning Emily’s diaper area. The diaper was pulled out and roughly tossed aside.

Emily laid back as Davina slipped off the edge of the bed. She leaned over the mattress and moved her face down to the caged genitals. Emily felt the babysitter’s tongue on her pent-up balls and she let out a louder moan. It was a very peculiar feeling and as it continued Davina worked her fingers in and out of Emily’s backside.

“I can’t take all this teasing…” Emily whined.

Davina didn’t stop her tongue or her finger but as Emily was starting to feel her arousal reaching a fever pitch the touching stopped. She was breathing a little heavily as she looked down. Davina was crouched between her legs and, for the first time since they had started, she wasn’t touching Emily at all. She looked a little conflicted, a little concerned.

“Remember when I said we were more alike than you thought?” Davina said.

Emily nodded. She had an idea where this was going. She swallowed nervously and, as Davina started to stand up, her eyes grew wide. Her eyes fell to Davina’s waist where her panties were now bulging out. Davina reached down and hooked her fingers underneath the waistband of her panties and slipped down her legs. Emily’s mouth fell open. What she had were princess parts, what Davina had was a huge cock.

“Wow.” Was all Emily could manage. She couldn’t take her eyes off it.

“Is… Is it Ok?” Davina was suddenly looking very self-conscious and yet somehow it was only making her more endearing to Emily, “I know you’re a lesbian and-…”

“It’s fine.” Emily said quickly. She continued after a quick chuckle, “It would be kind of hypocritical if I said it was a problem, right?”

Emily smiled and Davina giggled. The babysitter squeezed some lube on to her dick and started getting into position. Emily felt a little nervous. She’d had fingers inside her, she’d had toys also put up there also, but this would be the first time experiencing a real cock. Emily scooted back on the bed a little and Davina slid forwards on her knees. The dick swinging between Davina’s legs looked even more intimidating up close, it seemed bigger than anything Emily had experienced before.

“Don’t worry.” Davina said, “I’ll go slow.”

Emily’s legs were rolled up as if she was getting an old diaper taken away and then a pillow was slid under her to create a better angle. She could feel her own special parts, tiny compared to what she was looking at, wanting to break free of its prison.

Emily looked down the length of her body as Davina angled herself towards Emily’s already lubed and loosened hole. Emily laid back and did her best to relax as she felt the soft smooth head of the penis touching her. Despite her apprehension she was turned on enough that she felt as if her butt was dilating itself to welcome the intruder.

“Ready?” Davina asked. Her voice was a little huskier than before.

Emily nodded her head. She took a deep breath and then let out a gasp as she felt the blunt tip of her babysitter enter her. She winced slightly and Davina stopped when just the head was in. Emily was thankful for her lover’s thoughtfulness. It gave her time to adjust to the size. Davina pulled out and pushed in again, always to the same shallow depth. When Emily looked down the length of her body to where Davina was kneeling, she could see that the babysitter was visibly holding herself back.

Emily felt so naughty and yet that just made everything feel even better. A real dick felt very different from any of the fingers or toys she had experienced up to that point. She could feel its warmth and the way it twitched. To show that she was ready for more she, very slowly, eased herself closer to Davina and impaled herself on the next few inches. She felt the ridge of the head roll over her special place and she arched her back with a moan. It was hard to believe she hadn’t even taken everything yet. Davina was so big!

Davina pressed in a little further. Emily noticed the woman was always watching her face and seemed to know exactly when she had to pause and allow Emily to adjust. A few times, Davina pulled out fully only to go back in. Slowly but surely, Davina was working her way deeper and deeper into Emily.

“You really are very vocal.” Davina said with a smile, “I love it!”

Emily blushed harder. Every time Davina started to move Emily lost her mind a little, she wasn’t able to keep quiet or stop her body from reacting. She bit her lip as Davina slipped in a little more. Finally, after minutes of teasing Davina was fully seated within Emily’s butt. Emily had never felt something so deep inside her. She felt so full, and it was glorious.

Now that Davina’s body was pressed right up to Emily, she was able to lean forwards and on top of the prostrate woman. Emily felt Davina’s tits against her own, she wrapped her arms around Davina’s back as they kissed passionately.

Emily felt Davina’s hips starting to pull back and push in. Slowly, she was fucked and she could feel every inch rubbing against her prostate sending bolts of electricity through every nerve in her body. It felt incredible.

Emily’s hands wanted to touch every inch of her lover’s skin. She ran them up and own Davina’s back and then brought them to the front to start playing with her nipples. Davina’s thrusts started to speed up and she was going harder and deeper, each push eliciting another breathy exhalation from Emily’s quivering body.

“Do you like that?” Davina asked as she shifted up another gear.

“Y-Yes…” Emily moaned. Her fists grabbed at the sheets and she thrust her chest in the air.

The cage constricting Emily’s penis had never felt tighter but she didn’t feel any pain. Instead, the electric pleasure surging through her body meant only pleasure was reaching her brain. It was an entirely different kind of excitement compared to using her dick and yet it felt glorious all the same.

“More… Faster!” Emily whined as she moved her hips in time with Davina’s thrusts.

“What a slutty baby.” Davina growled.

The words made Emily howl in yet more pleasure. Her hands went to her legs. She spread them apart in a bid to give Davina completely unrestricted access. When she looked up and saw Davina’s breasts bouncing, combined with her own hole being filled, it was enough to make her princess parts feel like they were going to explode.

Just when Emily assumed things couldn’t get any hotter Davina adjusted her position slightly. Now, instead of brushing over the prostate like a feather duster, Davina’s cock was slamming into it. Emily let out a scream of pleasure before stuffing a fist into her mouth to quieten down. For a second it looked like Davina was worried she’d hurt Emily, but as Emily continued to pant and moan as if she was in heat the babysitter quickly returned to the rhythm that had her lover thrashing her. It was getting to be like a bucking bronco.

“Oh god, when you move like that…” Davina gasped, “I think… I think…”

Emily didn’t need Davina to finish the sentence because she was feeling exactly the same way. She could feel a ball of pressure behind her caged dick growing in size and intensity, at any second it could explode. It was a more intense feeling than anything she had ever experienced with access to her dick.

Davina lowered her shimmering body until she was lying on top of Emily. The woman on bottom wrapped her arms tightly around the babysitter and felt the soft exhalations and slightly sweaty skin. She felt like she could feel the cock inside her swelling a little more as Davina gasped into her ear.

“Cum in me!” Emily whispered in a strained voice.

Emily opened her legs until they almost strained from the effort and felt Davina jackhammering into her hard and fast. She felt on the verge of an orgasm herself and having Davina lying on top of her, her body rubbing on her tits and princess parts, it was the extra stimulation she needed.

“Ah! Ah… Ugh!” Davina pushed in a few more times. It seemed like her powers of speech had been taken as she simply grunted.

Emily didn’t need words to tell her what was happening though. She felt the cock rubbing against her pleasure button swell a little more as it buried itself to the hilt. This time it didn’t pull back and Davina instead tensed up.

Deep inside her, Emily felt the cock swell for a second before it started pulsing. She gasped as she felt a warmth spurting into her. She wrapped her legs around Davina’s waist and wantonly rubbed herself against the gasping woman.

“Ah!” Emily squealed as she felt the ball of tension in her crotch cracking with pressure, “Mommy! Mommy!”

Emily was barely aware of what she was saying as she felt her princess parts seemingly explode in electric pleasure. She tensed up and screamed in pleasure as she felt herself spurting on to both herself and Davina. The orgasm stretched on for a full minute before she suddenly relaxed and fell back against the bed with Davina, still inside her, on top. They were both sweating and panting.

“That was… incredible.” Davina panted.

Slowly, Davina slid backwards. Emily let out a breath of sensitive pleasure as she felt her lover’s length sliding out of her. When the dick finally came free, she felt some of the sticky seed left behind dripping out of her.

Davina took some baby wipes and started cleaning the sticky mess that had been left on both of them. Her movements were slow and Emily, through half-lidded eyes, could see that the babysitter was still recovering as she slipped a fresh diaper underneath Emily’s ass. At least now the cum leaking out of her wouldn’t stain the bed. Once freshly taped up, Emily saw Davina lean over her and plant a kiss on her forehead.

“Amelia sends her love.” Davina said quietly, “And says “Happy Anniversary.””

Emily smiled sleepily in return. She turned so she was lying on the bed with her head on the pillows as the side of the crib was lifted up and locked into place. She was very tired now and after a few seconds spent collecting her clothes Davina headed to the door.

“Have a good rest, baby.” Davina said, “And thank you. I had a wonderful time. You’ve been a very good girl and I’ll definitely be telling Amelia that.”

Emily smiled and closed her eyes. Davina switched off the light and closed the door. It wasn’t long until Emily fell asleep. Her last thoughts turning to her wife. Despite everything she had discovered this evening about her wife keeping all her diaper interests away from her, the revelations that the life she was living was at least partly due to Amelia’s fetish, she couldn’t feel too badly about it. Not in the afterglow of such wonderful sex.

Maybe Amelia wasn’t so bad after all. She had been the person to arrange all this just for Emily after all. Unconsciousness drifted over her as she smiled. She was Mommy’s good girl and she should’ve known better than to doubt her. Mommy knew best.
