Me, my wife and our bull have a marriage in a "menage a troi" for 20 years now and I've seen hundreds of times how our bull is pumping his seed deep into my wife and I enjoy it every time.
I love to feel pussy lips banging on my dick and balls. The problem is I am 20cm and that is rough for my lady. My ex had no problems fitting it in so I could slam it hard as I released my cum in her.
