My lover is straight

My lover is a real straight guy, a pure macho... And yet, he likes to fuck me so much that he dumped his girl for my ass! Since then, when he comes over in the evening, in his tracksuit and Costla cap, he orders me to get down on my knees to suck him like a slut. He shoves his dick down my throat, holds my head firmly to fuck my mouth. I feel his big cock harden on my tongue... Once he is well och', he tells me "get naked", he puts me on all fours and eats my ass like he would lick a pussy, before filing my little whore hole!
