Sucking on breasts

My boyfriend and I were having sex. I love breast sucking/stimulation as does he. He was sucking on my breasts pretty vigorously (I’m 25 weeks and have already started producing colostrum) and he informed me after that he was getting good amounts of colostrum. So now I’m worried that this could induce labor 😭 I’m hoping all is fine. And we’ve agreed to stop. But I can’t help but worry now. Do you think I should be fine? How common is it to really induce labor from that? Would it only take 5 or so mins of breast sucking?
