It wouldn't have been embarrassing if you hadn't already shared something with him.
If the donkey came to meet you with a hardon, he must have liked what he got the day before, and I'd say he gets his dick between your legs again.
when he was putting the dick to you, were you pretending to be a mare in heat, or another male donkey having gay sex?
Can you please giveus the back story on how the donkey fucked you in the first place?
to #4, it started out one day when I was over there mowing the lot he's kept in. The mower quit, and I had taken off the air breather to adjust the carb, and dropped the breather bolt in the grass. I was down of all fours looking for it when he mounted me. It supprised me that he did that, but at the same time it did something to me, and I just let him dry hump me. I knew he was dominating me, but I liked it, I ended up pulling down my jeans and shorts, but he never got a hard on. This went on evertime I went over there for the next two weeks, then one day I was at the local horse sale, and I fingered a mare that was in heat. I left there and went to the neighbors, dropped my jeans and got down on all fours, he came right over and I held my fingers between my legs. I guess the scent was still strong enough, cause in a few seconds he mounted, and that time I felt his dick as he was trying to penetrate me. As he was trying he pumped out some precum, and the next thing I knew he was in, the head of his dick flaired, and he was taking me just like a stud would a mare.
