The store she led me to was one that had always sparked my curiosity, but one from which I had been forbidden from, due to my age. The store was called Leather 'n' Spice and had a bold sign at the door . "Now be a good boy," Marty said, "stay here and watch the bikes while I shop." She then entered the store. I noticed that the store was located next to a fast-food place, so I chained the bikes together, then went and ordered a malt, and sat at a picnic table, musing as to what Marty may be shopping for. About twenty minutes later, I saw Marty come out, holding a package, and see the bikes sitting by the door. I stood and walked across a parking lot to join her. Finally she spotted me and gave me a condescending look. Hands on her hips, lips pouted, she glared at me. "I thought I told you to watch the bikes!" "I did...from the restaurant..." "I said 'stay HERE and watch the bikes!" "I could see them just fine!" I said, defensively, as I unchained them. Marty said nothing. She just mounted her bicycle and rode off. I followed her back home.

As soon as we arrived, Marty headed for her room. As I opened the garage to stow the bicycles, I heard her calling to me. "Kyle!" she called out. "What are you doing?" "I'm putting the bikes away." "Okay." she said, "As soon as you're done, get ready for an enema session." My shaft immediately came to attention when I heard those words, and, logically, I hurried to complete the task.

Then I went to my room and as I took my sweaty clothes off, I heard Marty call out again. "In the big bathroom...NOW!" Stripped naked, I rushed downstairs and entered my folks' suite. As I walked, my hard-on swung from side to side. I found Marty in the bathroom, naked, as she filled her enema bag.

"I want you to do me first." she said, tersely. I was somewhat taken aback by her brusque manner, but a twinkle in her eye made me suspect that she was playing some sort of game. She spread a bath towel on the floor after hanging the bag on a towel bar. Then she got down on her hands and knees. "Okay..." she murmured, "I'm ready." Remembering what I had learned, I donned a rubber glove and smeared a bit of lubricant on my middle finger. Marty's pink rosebud peered up at me as I did so, and the sight did nothing but further excite me. I found myself wishing that I was the one to be getting the finger. My time would come soon enough. Parting Marty's cheeks further with my left hand, I teased her anus with my slick finger. I felt her back door relax, and I inserted my digit slowly, feeling her muscles twitch lightly, as Marty let out a mild moan. Soon I was in as far as I could go. I slowly rubbed her rectum, twisting as I did. She moaned and sighed quietly. Enough was enough, I thought, so I retracted my finger and removed the glove. Next came the nozzle. I lubricated it, and then gently approached Marty's rear entrance with it. She was sighing regularly (or would you call it 'breathing hard'?) by now, so I knew she was ready for it. The nozzle went in easily, as though sucked in by Marty's rectum. "You ready for the water?" I asked. Marty nodded, eyes closed, a look of rapture and concentration on her face. I opened the control about half way, as I had done before. A second or two later, Marty let out a mild gasp as the warm soapy water invaded her colon. Time passed and, slowly, the bag collapsed. I was amazed that Marty didn't flinch or complain once during this administration; on the contrary, she almost seemed disappointed when I told her that she had all the water. I gently pulled the nozzle out, and helped her get up when she asked. She was in no hurry to evacuate, but instead began making preparations for my enema.

"Aren't you uncomfortable?" I asked. "No; as you recall, we had a nice enema session last night, and we didn't eat much this morning. She reached for a glove and snapped it on. "OK..." she said, "Your turn." I knelt down on the floor and lay my head on the towel cushion which lay there for that purpose. I next felt Marty’s hand parting my own cheeks as I had done hers not long before. I pushed on my innards in order to relax my anal muscles, and the slick coolness of Marty's lubricated finger immediately invaded me. What had only a couple days before seemed like a discomfort was now giving me a warm, lustful feeling. My already hard dick reached a greater degree of firmness, twitching in anticipation, as a state of urgency began manifesting itself in my loins. Marty's finger moved slowly in and out, twisting as it moved. She had expertly located my special button and began a steady massage. I heard myself moan as I gasped in ecstasy, only to be disappointed by the rapid retreat of Marty's finger. A few seconds later, I felt the hard end of the enema nozzle nudging my anus. Once again, I caused my muscles to relax, and the nozzle slipped in easily. Without warning, I heard the ratcheting noise of the flow control, and I was soon feeling the warm invasion of soapy fluid into my bowel. As I knelt there, ass up and head down, I realized that Marty had finally decided to release the water she held. I heard the torrent hitting the bottom of the toilet bowl, and what may have been for some the embarrassing noises of gas being released. In the mean time, the water continued flowing into my bowel inexorably. At one point I felt the beginning of a cramp as it came, but I immediately began deep breaths, and the cramp went away before it became too painful. More water. Marty stood from the commode and wiped herself. Then she flushed.

"Your bag's about empty." she remarked. "Really?" I was amazed, but then remembered that I hadn't had too much to eat that day either, and thus had much more room in my colon for a first full bag. I felt the nozzle being pulled out and saw that it only dripped a bit as Marty let it hang over the bathtub. "How long..." I started. "As long as you feel like it." Marty interrupted, knowing what my question was leading to. I guess I held the bellyful for a minute or so, and then I went ahead and let it go. As I sat and expelled, Marty came close in front of me and rubbed my neck and shoulders. Her breasts were at an ideal height for me to use my mouth on them... I used my tongue and lips to tease first one nipple, then the other, to full erection, educing a lusty moan from Marty. Finally, she pushed away from me.

"You almost done?" she asked, "Time for a shower!"
