Man really is very hard presses lady, and not only in the anus, and in all the orifices on the body! Sometimes in the mood and want to fuck my girlfriend so hard when it blows her mind! It is interesting that after this kind of riding she just becomes silky! Just purrs like a kitten!
Well, half-brothers and half-sisters are not related at all, so it can't be considered something bad or immoral. It's no surprise that an adult guy and girl, with no regular sexual partners and almost daily being around each other, suddenly felt attracted on a sexual level to each other. Considering that the girl liked it (the guy then no question), I think they will continue to practice this kind of thing from time to time.
