Nearly made it inside

I’m 53 and a premature ejaculator , normal sex for me lasts roughly 30 seconds or sometimes 3 pumps, I’ve been like this all my life since my first sexual encounter at 17 but I’ve always managed to actually enter a woman well that is until last night. My parter of 15 years was feeling extremely horny and teasing me all night by sitting there in her dressing gown with no panties on flashing her pussy at me. After an hour of this and sitting there rock hard I went down on her. A couple of minutes in she says sit down I need that big cock inside, I sat on the couch while she straddled me about to take me inside, as she grabbed my cock and started to guide me inside I couldn’t hold back. The tip had only gone in as I felt my cock start to pulse and my ball’s getting wet as my load had already gone. She stood up and looked down at me sitting there in a sticky mess and laughing said damn you didn’t even get it in
