I think he did because his wife want everybody know that he is cuckold with small useless dick... I know for sure that two couples that they are friends knows everything about them...but for more people I don't know for sure...
Funny coincidence, thats exactly how I got my dick sucked too yesterday night, same same position. I love opening my legs like that too, so she can have all access to all my erected member and my bouncy balls. Best way to unload them on my whore's face, jacking off while she sucks my balls. N
