The main context to take from part 1 (link in comments) is this bit,
*I was teasing her and I said something about making sure she cums before I do. To which she says that no guy has ever made her cum before. I didn’t believe this at all to begin with, she explained how it takes a lot for her to cum anyway and she usually gets close but has to take over to actually reach an orgasm.*
Emma and I agreed to meet up a few days later, but this time I was going straight to her place and we were getting food delivered. We had sex soon after I arrived and I won’t lie, it was like a rein-action of our first time (part 1) except this time I lasted a little over 5 minutes inside her death grip pussy. However, 3rd time lucky, I managed to last as long as I usually do. Thank fuck.
