pounding my wife long and hard

Well a few weeks ago my wife and I went on a short getaway to upper NY state.

. We planned this with my parents also. ( they were two room away)
Well one night we went and watched a rodeo and she commented on how big the bull were and she said she needs a hard dick tonight. well that got my attention right away, Well a few long hours later we are in bed and she starts to suck my hard cock like crazy but you see Iam on some meds that prevents a man from cumming , well i said i want to fuck you from behind so i get behind her and start to ram my cock into wet juicy pussy and she came about three time then i slow down just barly moving in her and i slip out a few times this drive her nuts, by this time i still have not cum and Iam getting sore for you see i also have a very bad back. she said she wants to make me cum and starts to suck me again well in my mind it was my cashier at work who has the biggest nipple i have ever seen throuh her tops only, so she keeps sucking and then all at once i get very hard harder than ever before and i blow my load deep into her thoat, after 45 min of sex, but it was the thought of my cashier that brought me off.
