"So I've always wondered..." Mandy's voice petered out. She thought of herself as a liberated woman and was surprised at how awkward it was to ask this question.
Joseph looked attentive and waited patiently.
"How does, uh, you know, Cialis work?"
Joseph grinned. So that was it. He had noticed Mandy fretting about something for most of the evening. He had wondered if it was something serious, like she was late or something. This was a relief, and easy. "When a man is sexually stimulated, the nervous system in the erectile tissue of a guy's penis releases nitric oxide. The nitric oxide stimulates an enzyme that produces a cyclic guanosine monophosphate (cGMP). The cGMP relaxes the smooth muscle cells in the penis. One result of this is that the arteries in the penis dilate and the blood can flow into the penis more easily. Another result is that the erectile tissue itself fills with blood. Both of these processes result in an erection. Cialis works by maintaining the level of cGMP in the smooth muscle cells." Joseph sat back, pleased with himself that he remembered all the biochemical crap and was able to explain it in a non-shaming way to his babe.
Mandy smacked him in the shoulder, interrupting his self-congratulatory reverie. "Well done, Stud! You said that with only one breath and with a straight face. Kudos. But how does it work in plain English?"
"Oh," Joseph's ego deflated, "why didn't you say so?"
"I did, you pompous ass. Now if you ever want to have sex again, you'll answer my question instead of lecturing me."
Hearing the word "sex" inflated Joseph again, so he took another run at an answer. "Well, Cialis doesn't make me horny but if something turns me on, it makes me harder quicker and it helps me stay hard longer. I don't lose my erection like I used to, so we can screw until you fall off and then some."
Mandy laughed. "Oh so that's your secret! No wonder we like those pills so much."
Joseph grinned, feeling that tell-tale tightness growing in his shorts.
"So let me get this straight," Mandy continued. "You didn't say anything about how long it has been since you last came. You just said 'whenever something hot happens to you,' or something like that."
"Yup, that's pretty much it," Joseph agreed.
Mandy grinned evilly. "So something hot happens to you and your flag pole stands at attention. Cool! How long does it last?"
"They say up to 36 hours. That's why we have been able to get two hot nights of fun out of a dose."
"Double cool!! Go get me one of your pills. I have an idea."
Joseph did as he was told, bringing her a Cialis pill and a boatload of curiosity. He cautioned Mandy, "I take half a pill at a time."
"Jeez. Then go cut it in half, you goof ball."
Joseph did as he was told. Women sure were confusing. Do what they ask and they scold you. Answer their questions and they scold you. He came back with half a pill, muttering under his breathe.
Mandy held up the pill and eyed it carefully. "It doesn't look so magic. Let's try something." She disappeared into the kitchen, delicately bearing her 10 milligrams of joy between her fingertips. Mandy carefully pulverized the dose in the mortar. She poured Joseph a scotch, She sprinkled the powder into his drink. She stirred it thoroughly, dissolving all of the powder. She held the glass up to the light; there was nary a trace of adulteration. She added a couple of ice cubes. She poured herself a scotch, too, and carried the glasses back to the living room.
"Drink up! I've always wondered what it would be like to drug my date." They toasted and drank. Joseph wondered if she had put anything in his drink beside his Cialis.
"How long does it take to work?" Mandy asked.
"It said about an hour but, for me, it's barely kicking in then. I give it a couple of hours."
Mandy looked at her watch. "OK. So I've always wanted to be a researcher. I just never found a subject worth studying. We're going to find out just what gets you hard and how long one pill lasts and how well you can keep me interested in this little project."
"Oh? Dare I ask how this is going to go?"
"You can ask but I won't tell you. I don't want to bias the experiment, you know. But I'll tell you this much, we are going to start by watching a movie. I think something 'stimulating' like
Basic Instinct
would be good."
What could Joseph say except, "OK"?
So they watched, with Mandy curled up on the couch next to Joseph, playing in his lap through every sexy scene. By the end of the movie, Joseph was so hot he would have ripped Mandy's clothes off of her, had she not attacked him first.
They had hot loud wet raucous sex and when it was all over but the cuddling, they both agreed that it was great to live in a house without kids and without shared walls. Then Joseph dozed off and Mandy slipped out of bed to finish setting up her experiment.
* * *
Joseph woke to find Mandy back in bed next to him. He afterglowed next to her for a bit but they soon agreed that no one would bring food to them so they should get out of bed. He was surprised to discover that his jockey shorts had been replaced with a pair of boxers. "What's this about?"
"My experiment depends on seeing how 'interested' your member is. It won't do if the little guy is held down by your briefs. We'll try the boxers but if those interfere with my observations too much, they will have to go, too," Mandy explained. "Now get dressed and we'll see how your 'outfit' works."
Joseph sighed. He had always shied away from boxer shorts for just this reason; he didn't want an embarrassing bulge. Clearly that was none of Mandy's concern. Or maybe that was precisely her concern. She left the bedroom and busied herself fixing a late night snack in the kitchen while Joseph dressed.
She hugged him intimately when he came into the kitchen, kissed him deeply, and ran her hand from his chin, across the front of his neck, down his check, over his stomach, past his crotch, and down to his penis, which she found oh-so-obviously pushing outward inside his pants.
"Nice! Cialis at work?" she asked.
