They did not know their mother would suck them off and ride their boners, but that’s not it. After a session of raunchy sex the mom puts a harness over her crotch and attaches a mean-looking dildo. And it goes up the shitter before the son can even say anything! A couple of thrusts, and he is enjoying his mom’s full control over his dearest hole.
Incest sex has never brought deeper feelings – in its literal sense, too. This is the new level of unty between mothers and sons, something very erotic and forbidden that they share between each other. Every encounter of this kind remains in the memories of both forever – and makes them yearn for another session of steamy love with a thick rubber toy filling the dear behind.
