Unexpected Changes

Lily climbed up her dad's chest, pulling herself up his body until the tip of his cock pointed right at her.

"You don't have to do this," Cloverleaf said, reaching up to caress her chest. "You can lie back and let me take care of everything."

Lily shook her head. "I want to do it this way. I barely exercise anymore. It's making me stiff, not moving around."

"Okay..." he took a deep breath. "Just go slow, okay. And if it starts to hurt too much, stop."

Lily said nothing. She loved her dad, and wanted to do as he said, but she knew better. Looking him right in the eye, she slipped down more than half of his length. While the big toy was supposed to prepare her for him, it was actually a little bit larger than he was, and having already crammed its entire length into her pussy, he was little issue. She swallowed his whole cock inside of her in two breaths, now sitting on his balls.

Cloverleaf placed a hoof on her hip. "Really?"

"Yup."

He took a deep breath. "It seems you're more practised than I gave you credit for," he smirked. "Okay, then. Go at your leisure."

Lily lowered her head. "I... I can't."

"Sure you can. You're a big girl now. I trust you."

"No, I... I mean I'm stuck. My legs don't want to push me back up."

Cloverleaf looked down at her hooves. They were convulsing. He could even feel her knees twitching on his hips. She could take his whole length, but it drained her ability to control her legs. If, as she had demonstrated to him, she was taking it while on her back, she'd not been practicing keeping her legs stable. She still had a way to go in her training.

Cloverleaf chuckled. "Alright, sweetie. Let's start slow."

Hooking his hooves under her hips, he lifted her a few centimetres and then gently lowered her back down. Then back up, and back down. With every slippery pump, she took a breath. As he pulled out, she inhaled, and as he pushed back in, she let it out.

He only went slow for a little bit. Once he could see that she was doing well, he picked up speed. Not a lot of speed; he wasn't hammering into her. Just a little bit more speed, and a few more centimetres of depth to go with it. He was certain she wouldn't break from this.

Something did click into place, though. Her exhales were deep, quavering moans, now. As she bounced up and down, she leaned forward, rubbing her body against his and just enjoying the ride.

"I'm going to go a little deeper," he breathed, his voice a gentle hum in her ear. "Just relax a little more, okay?"

He didn't do anything for several seconds, just continuing as he had been. It wasn't until her cheek rubbed up against him, signalling that she was nodding, that he began to change gears. He was waiting for her to give her consent.

With her ready, he lifted his hips and began to thrust. He wasn't moving her as much anymore, taking charge and going at his own pace. He listened, of course, for any objection, but the only semi-coherent word out of Lily's mouth was "yesch." She was into it.

He could feel her clenching up. She was tight around him already, but she wasn't relaxing. It wasn't to keep him out, but rather, to keep him in. As he pressed in, he was met with little to no resistance, and as he pulled away, she clamped down, trying to suck him back in. As much as she was loving it, it was all for him.

He slowed to a stop and then pulled her up off of him. "Wh-- What are you... Hah... I wasn't..."

"I know," he answered, setting her back down on the bed. "We're not stopping, I'm just starting to feel a bit sore, moving like that. So I'm switching us to a new position; that's all."

He moved her onto the bed, placing her face-down on the mattress. Once she was in position, with her chin on the pillow and her back legs spread with her tail up in the air, he stepped over top of her. With little warning other than lining himself up, he pushed into her once more, all the way down in a single stroke. He went slow, of course, watching her face for any discomfort, but she was in little pain, if any. In any case, she did not indicate any discomfort. Her big, goofy smile said the exact opposite, in fact.

Slowly at first, but then picking up speed, he began to thrust his hips forward and back, his balls slapping against her clitoris. She could do little more than pant and moan at him as his mighty rod impaled her tight snatch over and over. He was watching her expression the entire time, and it was pure sexual bliss.

It wasn't long before he was drilling into her at full speed. She was a melted, squealing mess by then, little more than a hot, tight wet hole for his cock. He'd lost all pretense of trying to keep his daughter safe. She was safe. Safe enough, anyway. She was in the hooves of somepony that loved her, and she was feeling great. She'd even cum a few minutes in.

More important than that, though, she was about ready to cum again. She was close; he could feel it. He had the capacity to keep going, as he could slow it down and still drive her over the edge, but he opted out. Picking up speed one more time to finish himself off, he yanked her hips back into his, spraying his load right into her, just as he had several months prior. His head was clearer this time, but now there was less danger. She was his little girl, and he'd do anything to make her happy.

And make her happy, he did. Filling her up caused her to cum a second time, and as she slowly recovered from that, he wrapped his hooves around her. It took an embarrassingly long time for her to realise that she'd been rolled over, as the only thing registering in her mind was the numbness of being on a cloud and being weightless. She wasn't a pegasus, but that was how she imagined that it felt.

When she regained her senses, she reached down and cradled her father's balls in her hoof. He was still inside of her, just like their first night together. Some of his cum was starting to drip out of her, but she didn't care enough to wipe it up. She'd have to leave the bed, find a towel and mop it up, and unless he carried her, that meant pulling him out, and she wasn't about to do that.

Instead, she nestled into his chest. It was warm, and he was hugging her. It was comfortable, and in less than a minute, she was out.
