It's fun to let a man with a bigger dick than you use you sexually. I like submitting to black men with big dicks. It just feels good. Then when they fuck your ass you feel very in your place. A bigger dick should fuck someone with a smaller dick
Never having had an experience like this, it puzzles me why a 'whiteboi' would want to be used like this. If it's a 'head' thing, it's notable that he's limp throughout, so not sexually excited, or is that the point? Maybe he can't get a hard-on and this is the only form of sex that he's suited to? That'd be quite an adjustment to make, though he seems to have adapted very well to this role! The comments below suggest that there are compensations to giving up your masculinity to a more assertive male, but I guess I'd have to experience it to understand!
