The aphrodisiac (or Dac as we called it) had both good points and bad points. It turned women into willing sluts, that was for sure, but it only worked on women who had been previously pregnant. Neither Timmy or I knew many of these - at least intimately enough where we could administer the Dac and control the situation so we didn't get caught.
Right now, Dad was the big problem. I'd promised Timmy I'd set things up so he could fuck my mother since I had already fucked his. He said I owe him, and I hate owing people. But with Dad hanging around there just wasn't a safe time to get Mom alone. So we waited. I knew sooner or later Dad was going to take a business trip. He was usually gone at least for one night if not two when he went on travel.
That doesn't mean I didn't stay busy refining the Ohlone derived aphrodisiac Timmy and I had come up with. My only "test subject" was Mrs. Cleaver, though. She'd lost her husband to a car accident, so there was no worries about running into adverse conditions - like Dad in my house.
While we waited and I tested out varying dosages of the Dac on Mrs. Cleaver, Timmy was thinking up strategies for maybe getting in bed with one of his mom's friends - or my mom's. Actually most of mine and Timmy's mom's friends were mostly the same. We live in a small town. At least we were now clear about who our "target market" for the drug needed to be for the drug to prove "useful". They didn't need to be married or anything, but they did have to have born at least one child. The Dac only worked on women who had gone through the physiological change brought on by childbirth. Or, at least, that's the only group we ever found that was susceptible to the effects of it.
Since Dad was home every night, we spent most of our time at Timmy's. I had an open invitation to experiment on her. Timmy's kinda weird. He doesn't want to touch his mom, but he was fine with my experiments with her. He said it made him feel like a total heel inside just thinking about fucking her, but he was OK with others. After all, his mom was only 39 and did go out on dates occasionally. Timmy assumed she was getting laid.
I will admit that Mrs. Cleaver appeared particularly tuned in to the Dac experience. Even though I kept reducing the dosage I gave her, she responded to each administration with the energy of a female cat in heat. The other thing I began to notice is that she had started to become more collaborative with our fucking. The last time we were together, I was fucking her doggy style with my finger up her ass (she really likes that), when she turned her head up to me and demanded that I fuck her ass. "Just get your finger out of there and stick your big prick where the finger was. PLEASE!!" She even spread her ass cheeks so I could use both my hands to line up on her pucker hole just right.
The feelings were wonderful, but what I really liked was that she had demanded for me to stick my dick there. She was participated in our fucking rather than just laying there and complying. Anyway, I was pleased to find a potential new advantage to long term Dac use. I had yet to find any negative consequences, although my database only contained one entry.
The other advantage of Dac appeared to be that memories of the sexual activities were hazy at best. They were more like dreams than true memories. Once she fell asleep after sex (which was usually pretty quick - the Dac did demand a price), the entire experience transformed into some kind of dream sequence. When she woke up, she was awake, alive, and raring to go, but there was no sexuality in any of her actions. Nor any mention of prior events.
OK. Back to Dad. It took forever, but finally Dad came home one night and announced a work trip. He would be gone for 3 days, but only 2 nights. That was OK, I was only hoping for 1. So I helped him pack and even drove him to the airport. I got back home around noon, and I found my mom in the kitchen making lunch. I asked if I could join her. While I was pulling out sandwich fixins, I noticed mom hadn't poured her drink yet, so I said I was getting some milk for me and did she want anything. She said milk was good for her, too. So, while I was reaching for a glass with one hand, my other hand was reaching into my pocket to retrieve the packet of Dac I had there in preparation. I filled mom's glass and left it on the table where she usually sat. Then, I went and poured mine, but kept it near me on the kitchen counter. The last thing I wanted was to confuse who got the Dac and who didn't.
After lunch my mother began to look fidgety. We'd just finished cleaning up after lunch and were sitting on the couch trying to find something interesting on T.V. The next thing I knew, she jumped up off the couch and started removing her clothes.
"Mom!" I cried, "what are you doing?" She looked at me with that glazed look in her eyes and said only one word.
"Hot", she said.
"OK mom. Let me help you. Let's get you to the shower first though. You can take off your clothes there and go take a cool shower. That should help." I said, knowing full well it wouldn't. I needed to get her to the shower and then call Timmy quickly. I led my mom to the bathroom in her room. Shit, mom already had her blouse unbuttoned and the tail pulled out of her pants. I could see her boobs, though they were still somewhat concealed by her lacy bra. I could see half her areola, though. They were huge, clearly larger than even a silver dollar. I wondered what her nipples would look like surrounded by those areola. Talk about a bulls eye...
I got my mom to the shower, but she wanted me to join her. It didn't matter to her that both she and I had clothes on. She just wanted both of us in that shower together. This was going to make a bigger mess that what I wanted to clean up later.
"Hold on, mom", I said "let me help you get out of your clothes first. I kneeled down and pulled her pants off and then her underwear. I was staring face to face with my mother's bush, It was big and black, but so were hey pussy lips. They made her mons more pronounced and her slit well defined. Meanwhile, my mom was pulling my shirt off over my head. I got the rest of her clothes off and aimed her towards the shower. She refused to go in without me. She kept pulling on my arm, so I acquiesced.
"OK mom", I'll come in with you but first let me get my pants off." I turned my back to her and slid my pants off. I had a raging boner and didn't want to incite my mom further with it. I knew the power of Dac. I pulled off my underwear and hid my dick behind my hands as I quickly stepped into the shower. This wasn't the plan. I agreed with Timmy that fucking my own mother really felt icky to my insides. And, I owed Timmy. So how to get him over here - and quick.
"Now, now dear. There's no need to hide your magnificent manhood from me." my mother said. She grabbed my hands and pulled them away exposing my full 7 inches of rigid boner. "Oh my", she exclaimed.
