Help his father with an involuntary erection

The man does not understand very well why but he has an involuntary erection and there is no one to lower that. WTF! Maybe he accidentally took a Viagra? Who knows how to fuck, but that which is between his legs has been like this for several hours and it starts to hurt. OMG !. Total that it will have to be his tender and beautiful daughter who helps him stop that erection, first he undresses and rubs his pussy with his father's cock, to see if it is enough and the man comes, but no! you will have to do something else: hit play and enjoy father and daughter incest ...
