Sorry I have only just noticed the response. Yes they did, under duress though. I have felt humiliated by the act, but enjoyed it much more than I thought I would. Since that I have had a few encounters with other bulls while with my exwife and with my exgf. Both said they enjoyed watching a cock enter me. My exgf wanted me to kiss one of her bulls and fuck him, but I could not bring myself to do either (still cant).
After the initial encounter, I was sore for a week after, but my exwife used her dildos on me after that and my exgf too in between meets, but I didn't do any more groups again, just in case
