Ultimate shoulder rides

Being carried is obviously the  point of  sitting on  someone's shoulders  and I agree with Trigger  that the rider should be in control regardless of whether the  person  he/she is sitting on  is moving or  stationary. I don't see  the  service of the  carrier to be any different  than that of  a  horse or donkey  except of course that  normally  the carrier  chose his position  beneath  his master.

Sitting on  another  person is  fun regardless of  how your sitting on  him  and  it  implies a position of  dominance and  control  regardless of  the basis of the relationship.   When  I was  being  carried  by  my friend's  submissive friend, his distain for  being beneath  me  brought about a resentment of  him   but also  a feeling of control  and  dominance even though it was  my  friend's  control of him  that  put him  beneath  me and he  could have made me  get off and ended  the ride if he really wanted to.
But when  we  rested  our respective  carriers , I  dismounted on the  first rest period  while  my  friend remained sitting on his hunched over  carrier, basically  using  him as an inanimate seat . I knew  my friend enjoyed  sitting on  people ,  which I  assumed involved  the  sensations as well  as  his dominant  control of the  person beneath  him.
Because of  my carrier's  clear resentment of  me,  which he  demonstrated  previously , I treated  him  similarly during the second rest period and though  I  dismounted rather than  sitting on  his  neck  while he knelt  as  my  friend did  astride  his  carrier,  I  made it a  point to sit on  his  hunched over  back  rather than  standing  as I had  previously. Because of the  position,  I didn't have my full  weight  sitting on  him,  but  enough to burden him and  make  him  less  comfortable and demonstrate  my disregard  for  him.
Please  understand  that normally I  would have  been kinder  to  my  carrier,  but this  man's behavior  annoyed  me.

It's interesting what Audreyb says. I presume that Audreyb is female? If so her experience is similar to the experience of a young female and her boyfriend, both of whom I worked alongside many years ago while doing a summer job.

Her boyfriend was a guy in his late teens who, while on the part-time summer job at a yachting centre, had a friendship/relationship with a gay guy in his early 20s with whom he also worked.

Not unnaturally, the teen guy's girlfriend resented his friendship/relationship with the slightly older gay guy. But the gay guy did things for the teen guy that his girlfriend didn't like doing or didn't want to do. So to keep her happy, the teen guy told the gay guy to do things for his girlfriend one of which was to give her shoulder rides and let her sit on his shoulders. The girlfriend particularly liked doing the latter.

Unlike the submissive guy that Audreyb rode and who resented Audreyb riding his shoulders, the gay guy actually liked the teen girl sitting on his shoulders and occasionally riding on his shoulders. She always wore tight blue denim jeans so it was easy and comfortable for her to sit astride a guy's shoulders.

At the time, I thought that the teen guy's girlfriend (and she was a teen herself) liked sitting astride the gay guy's shoulders (indoor while watching the television) partly or even mostly because he had to let her do that and she knew that and she also knew that she had control over him and because of that she'd regularly sit on his shoulders watching television for half an hour or longer even when being sat on for that length of time became uncomfortable for him.

There again, the gay guy may have enjoyed the experience of being dominated in that way by a girl in her mid-teens. Presumably, not many gay guys of any age would ever normally have that kind of experience with a female. Happily, a few months later she started having horse riding lessons and switched to riding real horses!
