Black men having sex with freshman definitely happens. My GF for instance, before we were together. Same guy she was having sex w/then is the same guy who has sex with her now.
Before I was with her, I used to have a black roommate who had sex w/white girls, too. Loved to see/hear him getting plenty of sex/head while I was getting absolutely zero pussy. Lots of cutie freshman having sex w/him for sure.
Sometimes it was girls from bars or that he knew from college or wherever, but the best was when it was girls from work. Especially if it was a girl I had a bit of a crush on. Nothing's better than thinking you might have a chance with that cute girl from work, then later that night she shows up unexpectedly at your apartment with a real man.
At first it was embarrassing to see it happen. But after seeing it happen the first few times it just felt natural. I started to get happy/excited when it happened to the point that I started encouraging it.
One of the most humiliating times was when I told him I had a crush on a cute & petite brunette freshman that I was super into. I asked him if he thought she was cute and he said that she "looked like fun." tl;dr, he ended up having sex with her in addition to the other girls he was already getting sex/head from. All I could do was jack off in my room while listening to it. He absolutely deserved it.
It was embarrassing at first, but after him having her too became normal, I was really happy about it. I still had a huge crush on her but wasn't going to disrespect him by trying to do anything now that he was having sex with her. He definitely deserved her more.
I stayed pussyfree the whole time I lived with him. It got to the point where when I met a white girl I stopped thinking about wanting to be with her and would much rather get to hear him fucking her or her sucking his dick instead.
