I have fun playing with my stepdad's big cock and I don't let him cum

I'm in love with my stepdad's huge cock, it's very long and when he sees me it gets very hard, I've played with it for a while and I've given him a delicious blowjob, it feels as rich as it beats inside my mouth but I haven't let it cum to leave him wanting and motivate him to put it hard in my pussy when we are alone again at home
