Almost immediately after knocking, the woman confirmed she was ready for Helena. The statuesque scientist opened the door and walked in, making sure to lock the door as it closed behind her. Helena had half expected Stacy to be nude when she entered, but the woman had chosen only to remove her pants and underwear. As with most of the Futanari women in the refuge, Stacy's cock was above average in size, and was erect when Helena walked in.<em><strong>God, I hope this woman checks out clean,</strong></em>Helena thought to herself as she gazed upon Stacy's endowment.<em><strong>And sterile.</strong></em>"<strong>Before we begin, I feel I need to explain a few things to you, Stacy. First, I never explicitly stated that oral extraction wasn't an option at first. That was for vaginal extraction. So, let's get that out of the way. Second, I am relying on you to let me know when you're getting close enough to orgasm that you're about to ejaculate. I'm not looking to waste your sample by having it shot into my mouth. Much as I may enjoy such a thing in my personal life, this is not that time. Third, when the time does come, you are to use...</strong>" Helena walked over to one of the cabinets in the room and pulled out a fairly good sized glass beaker. The gradient lines on the side were difficult to make out from a distance. "<strong>...this beaker to collect your sample. You'll note that it's wide enough to fit your penis, should you wish to insert it to make sure nothing is wasted. It'll fit a liter of ejaculate, which I've yet to see. Finally, and most importantly...</strong>" Helena reached into her hair and pulled out what looked to be a wooden chopstick, which was holding her jet-black hair in a bun atop her head. Her hair cascaded down below her shoulders as she stepped toward Stacy, closing the distance between them. "<strong>...this is for scientific research. As enjoyable as this may be for you, I would prefer it if you don't try to force the issue with me. Your time will come. For now, I want you to relax and try to enjoy yourself.</strong>"<br/><br/>Helena closed the distance between them until her body was practically pressed against Stacy's. She reached out her hand and gently wrapped her fingers around Stacy's erect cock. As with most of her other Futanari test subjects, the skin of Stacy's cock was smooth, another curiosity for Helena. Some Futanari grew a lot of hair, some didn't. Whether Stacy shaved down below, or whether it was genetic, Helena didn't much care at the moment. She allowed herself to enjoy the feel of the woman's endowment in her hand as she began to stroke it gently, her fingers moving slowly up and down along the shaft. She lingered for a moment at the bulbous head, letting her fingers trace a line around the edge and seeing Stacy's response to that. Like most Futanari, and most men, the woman seemed to enjoy the sensations Helena's touch elicited. "<strong>If you feel the need, please be gentle with my hair. I've spent a lot of time growing it out like this, and I'd prefer to keep it long for the foreseeable future.</strong>"<br/><br/>Helena then slowly knelt before Stacy, her hand continuing to gently stroke the woman's erect cock. Up close, she could see the signs of razor burn and some very light stubble, indicating that the woman had shaved herself bare. Helena made a mental note of that, as it was something else she wanted to test for in the woman's genetics. Secondary sexual characteristics were a part of the dimorphism Helena was studying. However, she put that aside for the moment, marveling in the feel and appearance of Stacy's cock. Visually, it wasn't much different from any of the others Helena had seen. However, the novelty of Futanari hadn't worn off yet, and Helena saw them as the best of both worlds. Slowly and somewhat teasingly, Helena moved her mouth close, letting her fingers continue to dance around the perimeter of the head of Stacy's cock. When she felt that the woman was becoming a bit frustrated by her hesitation, Helena began wrapping her lips around the head of Stacy's cock. Her tongue softly sweeping around the edge, mimicking the movement of her fingers. She did this for a moment or two, reveling in the taste of the woman's skin before letting her lips slide down the length of Stacy's cock, her tongue cradling the woman's endowment as it moved deeper into her mouth. Helena then pulled her head back, her lips reversing direction as her tongue teased the shaft. Helena let the head part her lips, and gently kissed the tip. "<strong>Gods, I always forget just how wonderful a Futanari's cock tastes.</strong>"
