Cowgirl style

Trixie was on top of Josie now, one hand grasping Josie's huge, rock-hard cock and guiding it inside her.

"Oh! Oh, that's big."

Trixie reached out for the wall to steady herself, then clasped Josie's hand when she raised it, their fingers interlocking.

"Really big. Oh wow."

She lost her lighthearted manner for a moment, a nervous look fluttering across her face.

"You're gonna have to let me drive, okay? I mean, I've taken big ones before, but it takes a bit of adjustment and, well, with you being so inexperienced..."

Josie felt her face flush as she nodded. The desire to grab Trixie's hips and just push as deep as she could had been there, but she had held it back. As much as her lust wanted her to just fuck, fuck, fuck she was still in control. Somewhat, at least.

She lost a little bit of that when Trixie started to move. Up and down, slowly rotating her hips in tiny circles to work Josie into herself, drawing slow, shuddering breaths.

"Oh yes. So good."

Josie dug the fingers of her free hand into the mattress to keep herself under control. She had never felt anything like this. Jerking off was nice, but this? This was on a different level.

Trixie was moving faster now, pausing sometimes to go just a little bit deeper, inch by slow inch taking more and more of Josie's cock inside her. Time after time Josie thought she was a second from a massive orgasm, but somehow Trixie kept her right on the edge. She couldn't tell if it was the way she adjusted her pace just right or if it was something she did with the muscles in her vagina, but something she did let Josie come to the precipice again and again without falling over. It was agony and frustration and pure pleasure all mixed up and she loved every second of it.

When Trixie finally lowered herself fully down on Josie's cock they were both shining with sweat, their bodies trembling. That's when Trixie really started moving.

Josie could hardly believe it when she looked down from Trixie's face to watch herself go in and out of the other girl's tight, wet pussy. It looked like her legs should have been dislocated; she half expected to see her stomach bulge when she plunged herself down, making them both gasp.

Whatever Trixie had been doing before, she wasn't doing it now. Josie felt herself rushing towards the edge, a wave building inside her that nothing could hold back.

"Are... are you... ready?"

Trixie was breathless, her eyes shining as she fixed her gaze in Josie's.

"Yes! Oh god, yes! I'm ready! I'm..."
