"I automatically bend over the foot of the bed after removing my clothes and placing them neatly on the chair as Mistress expects. In a stern yet soft voice I hear her say "Spread. It's asshole…and balls day.", "Yes Mistress" I say, as my cock instantly becomes rock hard as I reach back to spread my asscheeks for Mitress. "Well, your cock seems to happy about this, maybe I'll show it a little attention when I'm done; if you manage not to cum during our session that is." Then I feel a stinging across my asshole, and my cock starts to leak."
"My boss told me that she got me a yoga ball chair because they are more ergonomic. From the smirk on her face, I think she just likes walking by to see how hard my cock has stayed all morning with this dildo up my ass. She just came in to let me know that she has invited a few of her business partners over for lunch and that I'll be the entertainment, she wants me to show them how long I can keep stroking my cock while bouncing hard on my new yoga balls dildo without cumming."
