>>53224052Titfucks can actually feel great, but of course they need to be big enough. An american D cup is frankly bare minimum, it should be E or bigger, you really need it to be overkill.
The other issue is most women have no idea how to do it right. If they're dexterous they can put a man's torso on her lap and stimulate by plapping up and down, but most get tired or simply have a poor grip, this is an expert position.
The best/realistic way to do it is the woman drapes them over you, so that she (or you, or both!) can grip the breasts while the man simply fucks the breasts, this gives you maximum coverage, uses gravity to your advantage, and usually ensures a nice solid grip on both sides to give the dick proper stimulation.
That shit you see where the woman is on her back is terrible, porn-only. It may be erotic to look at but it's very hard for the breasts to maintain pressure on the dick
