Sibling Sex; Doctor Approved

You and Andrea looked at each other in a panic. You were going to have sex with each other for the first time. On top of it being sex between a biological brother and sister, your mom and a complete stranger would apparently be watching as well.

"Now I understand this is unorthodox" Dr. Farmer says, "but I need to see the act so I can diagnose the problem." "Andrea" Dr. Farmer continued, "I would like you to stand up and remove your clothes."

Andrea took a deep sigh and with no resistance at all stood up and began undressing. Soon she was completely nude in the therapist's office. She looked ever hotter than she did in the shower; with her hair and make-up done she was the hottest human being you'd ever seen.

As soon as Andrea finished, Dr. Farmer continued with her instructions. "John, I would like you to remove your pants and underwear. I understand you may be self-conscious about your weight since Andrea made her comment earlier. You may keep your shirt on if you wish." You stood up, shaking, and began pulling down your pants. Soon you were nude from the waist down. You took a moment to survey the room. You were standing there, penis fully erect, with a look of fear and excitement in your eyes. Your mom and the doctor each looked like nothing unusual was happening. Your sister looked bored.

"Alright John, please sit on the couch. Andrea, please straddle his lap and begin intercourse." You didn't sit on the couch as much as you fell backwards out of sheer shock. As soon as you hit the couch cushion, your sister came over and climbed onto your lap. She put both her hands behind your neck. Her large breasts were now just inches from your face. In one quick movement her pussy engulfed your rock hard cock. You were now fucking your sister.

The feeling was sublime. Her pussy felt warm and moist; it grasped your dick like a glove. This wasn't just the first time you fucked your sister, this is the first time you'd gone farther with a woman then some making out. You now understood why people go crazy over sex. It felt incredible. Your sister started bouncing up and down on your cock. You couldn't wipe the smile from your face. Your sister still looked bored. No moans of pleasure or comments from her. She looked like she was doing her homework.

After only 30 seconds or so you shot your load deep into your sister's pussy. Without any fanfare she got off your lap, took a seat next to you on the couch, grabbed some tissues from a nearby table, and began wiping your cum from her pussy. You looked up at your mom to see her smiling. The doctor was taking notes.

"Alright Andrea, tell me about that experience" the doctor asked. Andrea replied while laughing, "what experience? Shit lasted like, 30 seconds!" The doctor's eyes got wide. "Andrea, would you say you're experienced sexually?" Andrea, still laughing, responds, "yeah, you could say that." The doctor asks you the same question. You respond that what just happened was your first sexual experience.

"Alright, I see the issue here" the Doctor says. "Andrea is used to having a more experienced sexual partner. That being the case she looks down at the idea of having sex with her brother. John, having no sexual experience, is afraid to be the dominant partner that Andrea wants. Andrea, I need you to be the initiator of sex for the time being. Once John gets comfortable he will be able to perform at an acceptable level. Is that clear?"

You both nod your head. "Alright everyone, this ends our first session. Please put your clothes back on. I will see everyone again next Saturday." As you got dressed, your body still shaking from what just happened, you heard your mom say something odd to the doctor. "Thanks for your help Dr. Farmer, I appreciate that you did this for free too" your mom said. "No worries" Dr. Farmer responded, "I just want to see these two in a happy, healthy relationship." It appeared that even strangers who hadn't ever met you or your sister felt compelled to keep you two together.
