One of the reasons you exercise, as well as being healthy, is releasing endorphins. Anyway, its perfectly normal if sometimes you dont feel completely happy after your jogging routine. If you come home and, by chance, your girlfriend, Czech Jennifer Jane, is in the shower releasing endorphins with her wet vagina, then the best thing to do is taking this chance and going to the bedroom to continue the exercise fucking in cowgirl and missionary positions until you are emotionally satisfied.
