Ignore my Dad!

(I play Dad and Son)
MC (son) and YC have been an item for over six months now. The sex is good, we get each other and both of us are happier than we probably thought we'd be when this whole thing first started out. Oddly enough I've been reluctant to introduce you to my Dad: in the past, girlfriends have always had the hots for him and even though you've promised that won't be the case- you haven't met him yet. It's his 42nd birthday this weekend though and that's all about to change. Will you be able to resist this prolific DILF? (I dunno, maybe?)
