Grandpa-in-law walks in on you changing and instead of turning and walking away he just lingers there. This plisses you off and you call him a pervert and shutting your door. You can't help but notice that the old man had such a big bulge. You can't get it out of your head ask him to come to your room where you tell him you want his veteran cock. You give him a blowjob and then you guys have sex in doggy and then you ride him until you have a good orgasm, and you help him to have one after 10 years of being without. Your pleased to always help a veteran. You thank him and remind him you will be back to visit. Old geezer had a nice cock.
