Slut sister enjoys threesome with sister and her boyfriend

«Instead of competing with each other for a dude's penis, the girls agree that they will work together to bring its owner to ejaculation. They are well aware that competition between them will not lead to anything good, so they do not even want to quarrel. However, the girls manage to caress the dick with their mouths together, and then they still have to take turns getting it into their vaginas. Some of them will get more slotting, and some less, but this always happens in any group sex, so mistresses should not worry about this!»
