She has the big one

"OH... OH... AH..." You hear Jane's voice rising sharply. You feel her whole body shudder and jerk. Outside, you can hear her fingers desperately rubbing her clit. "OH FUCK, I'm-- AH!" she's cut off as a huge throb rocks her vagina. Before she can recover, an entire train of throbs squeezes you in lightning succession, each stronger and longer than the last. With each hard squeeze, you hear Jane grunt, steadily moving from a low sultry groan to a squeak as she became more and more overwhelmed. When her vagina finally relaxes, you hear her, distantly, panting. You try to move, but when you do, you hear her groan and say "if you don't stop moving, we're going to be late." Then, there's two loud thuds as she pats her pussy, followed by a shift in gravity as she sits, and then stands up. She's still very wet, but you don't feel like you're in danger of falling out. That actually wasn't normally a thing with most women at your size, you'd found. "Ready to get back to work? Should I stop and get us some breakfast?" You hear her ask. You give a big stretch as an answer and you hear her say "okay, that's a yes".
