I'm only 15 but I remember at my cousins cottage on a lake we watched a really old TV with like 4 channels that were all like fuzzy, when I was like 4 and there would be like glimpses of BJs and tits in the fuzz on one channel, yet I didn't realize what it was until years later when i learned about sex, hahaha.
This thread is pretty fucking weird though and I didn't get it at first. OP is slightly creepy
