She seems to want to take a closer look

She pushes her glasses up on her nose again and stares at at your drooling cock. She thinks for a second and then places her hands on your thighs and seems to be leaning in for a closer look at your dick. But instead of observing she engulfs and rams herself halfway down your length. You moan out in happy surprise as she has forgone any container to get her samples and gets it straight from the source.

You feel yourself hit the back of her throat and stop there. You savor the feeling of being yet again in her mouth and then you notice something that surprises you.

She’s actually gagging! Her face is turning red and her eye’s are watering, so you get worried and try to place a hand on her head to try to move your dick out of her throat. But she actually slaps it away and she looks up at you with water shot eyes and seems super annoyed.

Giga brained Jane doesn’t seem to have your girlfriends deep skill in deep throating.

You get a mischievous idea now that Jane has a form that doesn’t seem to have her default sex goddess skills. It would be a waste to not find it’s true limits.

You gently grab her head again and before her teary eye’s can shoot you another “fuck off” look, you ram your hips forward. You feel your dick easily slide forward deep into her throat. You feel her gasps around your length as she gags and her face gets redder. Her teary red shoot eye’s look up at you and you can’t help to give her an amused grin.

Despite her gagging, red face, and being a general mess, she locks eye’s with you. You notice her glint and get a bit spooked, but cant do anything but moan as she starts working your dick over.

She clumsily clamps her lips around your length as her tongue starts wrapping itself around your pulsing length.

You instantly erupt into her throat which causes her to gag some more. In a fucked up way her gagging is causing her throat to clamp hard around your length which in turn makes you cum more which in turn is making her gag even more.

You pump more and more down her throat. The pleasure is different as your girlfriend gag-milks you, but as the “examination” goes on she seems to be gagging less and less.
