A Clinical Cleanup and a not so Clinical Proposal

Your semen fills up the cup easily. Evelyn shows such a dexterity in recollecting it that you barely even notice the process in your post-orgasmic stupor, your face still buried in your sister's flesh. You see the doctor lifting the cup, looking at it closely under the light. "The texture and color seems correct. The amount is... satisfying."

"Would it be enough?" Asks your sister. Her voice manages to startle you, but it is obvious that, unlike you, she has being paying attention.

"More than enough. I'll send you the results as soon as I have them."

Right them, you decide to ask: "Wouldn't the lotion mix with the sample?"

The two women look at you with surprise and curiosity, the kind of expression that any woman has when she hears a man making a halfway intelligent remark: like she has been a witness to some remarkable curiosity. "Oh, that's no problem sweetie," says the doctor in a maternalistic tone "Our instruments are very advanced, they can easily separate the two."

"Mark," Says your sister behind you, still hugging you. "Why don't you accompany the doctor to the bathroom so that she cleans you properly? I have ...matters to attend now, before dinner... Will I see you here tomorrow, my big bro?"

"Of course!" you say. That makes the lady Lily smile, and that seems to be all that matters. She kisses your forehead as she sings her farewell.

A few minutes later you are in an adjacent bathroom with doctor Evelyn. A pristine place that still smell like the products used to keep it this clean. She kneels carefully before your deflated cock and with slow and methodical movements, she cleans it of all lubricity with an aromatic wet wipe. Once again, her fingers are so precise and soft. A part of you cannot help but to desire another round, even if you know that you shouldn't. "Your sister cares a lot about you, you know?" Says her, and to your surprise you sense a strange uneasiness in her. Is she so uncomfortable being alone with you? Your insecurities about being a low class male make a quick appearance.

"I know..." You say. "She has done a lot for me."

Your cock is clean already, but her hands still linger over it. You see two red marks appear in her cheeks to disrupt her perfect face. "Hey Mark... I know this might not be the best moment but... would you like to have dinner with me? ...Someday?" You heart begins to pound so hard that bloods starts to flow back to your cock. An attractive, elegant and well-positioned lady is asking you out, a doctor no less!, and she seems... shy. "I know this very nice place near the national museum... we could go there too if you want... We..."

"I would love to..." You say.

"G-good!" She says. She looks so beautiful smiling next to your cock. She gets up, looking into your eyes. "Next Saturday?"

"That would be... I..."

She cannot resist, her eyes bore into yours with sudden hunger as you speak, an inescapable delirium hidden in the depths of her iris. She doesn't let you finish, she almost jump into you, her lips seek yours, suddenly wet, her image of control and professionalism being broken in an instant. Her mouth is wet and warm, her tongue invades your throat with sudden possessiveness, finding the barrier of your teeth. Her hand never leaves your member, ever so carefully moving.

"I'm sorry... I couldn't..." She needs to breathe for a moment to get herself back to normality. "You are such a nice boy. I hope I didn't scare you..."

"No... of course not..."

"Good..." She strokes your cock again. "I'm not like other women... I know how to satisfy a man, I like to... I hope I have proven this to you..."

"Yes..."

"Saturday, then." Her lips find your again, but this time they are soft and brief. "You won't regret it."
