Kinky fidelity test : Full programme fucked by a stranger

My best girlfriend's husband is supposedly always faithful to her, at least that's what he says... but my girlfriend isn't so sure anymore - so she asked me to put him to the test because she knows that he likes horny blondes with big tits and she chose me ;-) But she insistently asked me not to take the game too far! No idea what she meant by that g can only say so much: He has full programme fremdgefickt! and ... aehh we didn't even use rubbers ;-)
