You can improve next time. Right now, keep it simple.

You put up with the minor dissatisfaction of not being able to get your entire length inside her in favor of making the present experience as good as you can for Jinx. If things work out, you'll likely be seeing her naked a lot more often. You can work on stretching her pussy out to accomodate your dick when the experience is not so new for her.

As it was, it had been a challenge getting as far as you have.

So you keep up with the pace, and Jinx doesn't seem to be complaining. Her insides flutter semi frequently, making her even tighter. If she wasn't as wet, you wouldn't be able to keep thrusting in and out of her. Still, it only takes a few minutes before the both of you are nearing the finish line, although you might be crossing it first: a fact that seems to encourage her to move her hips harder in order to set you off. However, you have access to one of her most sensitive areas. And once you feel yourself moments away from releasing your seed insider her, you gently pinch her clit between your fingers. The effect is immediate.

Her cry is almost loud enough to wake the dead. Your cum floods past the seal between your cock and her pussy, though it is quite watered down from her own fluids rushing out. When her climax dies down, she collapses beneath you and breaths heavily. You move to her side and join her in lying down.

Within minutes, you both fall asleep exhausted.
