Is This Normal?

I'm a 29 year old, recently divorced woman. I'm currently living with my sister and her family. Without going into all the details, I've been secretly spending time with my nephews friend from College. This kid has the biggest cock I've ever seen and without a doubt, cums more than what I've ever seen, too. It's like a geyser. He, literally fills me up with the stuff! Even several hours afterward, it's still leaking out and soaking through my panties onto whatever I'm wearing. The sex is great because he can last a long time, it's just getting to a point of me ending up at work, or wherever, with cum leaking to the point of soaking my clothes. Even the next day sometimes. I've fucked more than a couple of guys that came a lot, but never like this. I just wonder if anyone else knows of, or has encountered this before? And is it normal?
