For my two cents. Yes she did tell him she didn't want to have sex and then when the heavy petting continued she didn't say no. But facts are facts so he should have stopped.
But here is the reality. Remember when you were teens making out in the car or basement etc. When the heavy kissing and groping begins and it continues, a male's testosterone has no boundaries. Many a times I would be "Necking" with a girl I just met or a girlfriend. She would say to me this is as far as we are going to go. Then you have her hands on her breasts, legs pussy and her moans makes you think. Hey she likes it and maybe it might happen.
But at the very last second she says "NO". Dammit, I didn't have much of a choice but to stop.
So picture this scenario. Both are into heavy breathing and all that stuff, as a teen you only think with your dick and the dude did. The question that I would love to find out is why she didn't say no.
A good way of analyzing it Tiny. I also have been through a few close calls and did hit the home run. Always thought because I was a good talker and licker. Realized through my old age that I was wrong. The young ladies just had as much peer pressure from their female friends as we did from our friends.
Hope that makes sense.
