Congrats....but you're missing out big by not busting. I didn't bust my first couple times because I didn't know what the hell I was doing and didn't even know what cum was. But I was 13. You've had plenty of time to know the ins and outs (no pun intended) of the porn world and how shit works.

Maybe try putting her legs over your shoulders. It's one of the best ways to ensure I get mine.
But keep the condom on, or bust on her stomach, because it's a very well known way to make a baby in one shot.

But hey, good luck, and stay safe.
