The Mistress had the shower hose. "Now relax, and this won't hurt" she laughed. I'd never had anything inserted into my arse before, and I held my che...ks clenched shut as she tried to insert the enema. "Ok". She reached over and added some lubricant to the tip. The nozzle slid easily into my arsehole, and there was nothing I could do about it. "Open the door rex" she called to the pet "if he's going to be a little bitch let the everyone watch. The door was opened, and a small crowd started to. "He groans again, his kneading building in pressure. The tingles between my legs get stronger and I feel a wetness down there. I haven't felt like this in years."Peter, stop," I gasp.He stops immediately. "Did I do something wrong?" he asks, his hands still on my breasts."No," I say. "I just think we might be going too far." I just want to make you happy, Ms Gardner." His hands leave my breasts."I know, Sweetheart, but you're not James. You're my son's friend and I..."I gasp at a sudden. I just continue on non chalantly like I didn't notice. The three finish up about the same time, and began toweling off, finally dressing and leaving the bath house. I did detect one of them taking a quick glance back as he walked through the entrance. Giving a few seconds, I quickly rinse off, and walk to the entrance to catch a glimpse of what they were driving, and which direction they went, for future references :)Back into the shower to spend a few more minutes of the powerful jets blasting. Looking at the tube I could see a thick blob that looked like more than pre-cum travel the short distance to my mouth before I lost focus on it. I choked on cum as I struggled to breath. Looking up at Anna, she was smiling now. Gradually, more and more cum travelled down the tube and into my mouth. I had no choice but to swallow my own cum as I needed to keep breathing. I didn’t orgasm, but sperm kept flowing anyway. I must have choked on my cum for about 20 minutes until Anna started.
