I was confused as well but chalked it up to a very large, kinda late explosion of pre cum. I’ve seen some boys shoot precum before. Just not this much. Or, he had a second ejac later in his orgasm. Either way very hottt
In this vid (which has previously been posted on GBT I think many times) I've always been intrigued by the boy's "double-cum". He had a nice big single squirt of clearish boy-cum at 8:53. I thought that was it for him, but then after a long 10 seconds later he starts releasing several squirts of nice thick white "adult" cum 9:03. I've never experiences anything like that, or seen it an any other vids.
