“Um... yeah...” Linda mumbled still groggy. She was going to climb out of bed until she realized she had no panties on. As her head cleared she remembered she had left them next to Jeff, who was across the room. Linda couldn't just get up and go get them without Tess asking a bunch of questions. “I'll be down in a while.”

“OK. Jeff is still sleeping. Should I wake him up?” replied Tess.

“No, let him sleep,” Linda whispered. In reality she didn't want Tess to see her panties next to Jeff's mattress.

Tess left the room, closing the door behind her. She wasn't too quiet about it which irritated Linda. With Tess now gone, Linda got out of bed. Instinctively she tugged on her nightgown trying to cover what she could even though there was no way it was going to cover anything. She quietly crept over to Jeff's mattress to retrieve her panties. As she bent down to take them, he said “Hi!” It made Linda jump and she stood back up, pulling her nightgown down in front. “Last night was fun,” Jeff grinned.

“Yeah,” blushed Linda. She was now embarrassed even though last night he had seen, and touched, all of her and, although dark and she was covered, had watched her masturbate.

Seeing his cousin blush and trying to hide made Jeff wonder if she was OK with everything. “I already saw you so you don't have to be so shy.”

Realizing how silly she must look, Linda released her nightgown. “I wasn't blushing about that. I was blushing because Tess was going to wake you up and I knew you didn't have anything on. I was afraid she would embarrass you,” she lied.

Jeff, taking it as a challenge, pulled the blanket off him exposing himself. “Why would I care?” he countered. “So what if she sees me. Maybe she'd like to be seen too.”

“You'd like to see her?” Linda questioned.

“Sure! I like seeing girls,” boasted Jeff.

“Hmmm... maybe we can come up with a plan for you to see her...” For the next few minuted the two talked about how they could make it happen. Linda momentarily forgot about him seeing her again because she was engrossed in looking at his erection. They came up with an idea they thought might work. Linda finally looked at Jeff's face and saw he too was staring at her pussy. “Can I have my panties? We should go downstairs before someone comes looking for us and sees us like this.” Jeff handed her the panties. As she put them on she added, “Give me a few minutes head start and then you come down.

The morning was uneventful. Linda's and Jeff's fathers had gone out and the remaining two adults announced they were going shopping after lunch and would then pick up the men. With the usual warnings and instructions – stay at home, no visitors, etc., they said they would leave after lunch and should return in about two hours. Tess wanted to go, but in a small car it was felt there would not be enough room. Things were working out well for Linda and Jeff.

The morning seemed to drag for Linda, but soon it was lunchtime. After lunch Tess drew the short straw so she had to clean up. Linda and Jeff went to the bedroom and started playing a game on his laptop. About a half hour later Tess came in. “I'm bored... What are you guys doing?”

Linda answered. “I'm helping Jeff study. He's going to be a doctor.”

“Yeah... right! He's too young for that. I'm not stupid!” snapped Tess.

“Oh? He's from the USA, remember? They do things different over there. Maybe you are stupid,” Linda retorted.

“Oh... Then can I help too?” Tess then asked, believing her sister.

“You're too young,” Linda bated.

“No I'm not! You keep treating me like a baby, but I'm not a baby!” Tess argued.

“You wouldn't want to do what we need. You're too much of a baby,” countered Linda.

“No I'm not! You tell me what I have to do and I'll do it!” Tess yelled back.

“Fine! You get on the bed and Jeff will examine you... unless you don't want to. It wouldn't surprise me if you chickened out,” Linda snickered. As she was speaking, Jeff shut down his computer and watched to see what would happen.

Tess sat down on the bed and sneered, “I will not!”

It was now Jeff's turn saying, “Thanks, Tess. You will help a lot!” That made Tess smile. “Lie down on your back and I'll start. If you would, pull up your tee for me, please,” instructed Jeff, trying to sound as professional as he could.

Tess pulled her tee up to the bottom her ribs and Jeff started to feel her belly. Linda breathed hard through her nose. “Just pull it up – ALL the way up. You don't have anything to see anyway and he NEEDS to be able to examine you, baby!”

Tess glared at her sister as she yanked the tee up to her neck. “Happy now?”

“Just ignore her,” Jeff comforted. “You're fine and no one but us is here so everything is good.” Tess settled some even though her boy chest was now bare. She giggled and blushed as Jeff ran his hand over her little nipples, but she liked the feeling too. “Now I need to examine the bottom, so push your shorts down as low as you want,” Jeff smiled. After a long pause, Tess pushed her shorts down about half way to her crotch, but left her panties as they were. “Um... those too,” Jeff instructed pointing to her panties.

“Oh...” Tess giggled as she pushed her panties down to her shorts, exposing her belly almost to her slit.

Jeff added, “You need to move your hands” Tess moved her hands and, as would be expected, the shorts snapped back up to her belly button.

“It would be easier if you just took them off, you know,” Linda suggested in a kinder voice.

“I can't just take my pants off! He'll see everything!” gasped Tess.

“So? He IS going to be a doctor, so it's OK,” Linda explained.

“No! I don't want to!” Tess protested.

“See? You're being a baby again! Look,” Linda countered as she pushed her shorts and panties to her knees. “It's no big deal! He's seen it all anyway!”

As reluctant as she was, Tess now had something to prove to Linda. She pushed her shorts and panties down as she lifted, sat up, and pushed them off her feet. She then grabbed the bottom of her tee, which had naturally fallen back into place, and pulled it over her head. She then settled back down now completely naked. “Stop calling me a baby!” She blurted.

For a moment Jeff just stared. He was seeing his second naked in girl of his life in as many days. Linda nudged him and whispered, “Go ahead... have fun.” Jeff reached out and resumed examining his patient.

Tess didn't move nor say anything; she was too mad at her sister to care about Jeff seeing her. After a few minutes of Jeff's gentle touching, she began to cool off and the realization she was naked began to settle into her mind. It was too late to do anything about it now though except keep her legs tightly clamped together. He was just looking and poking around though, which settled her a bit until he said, “Tess, could you open your legs a bit?”

She panicked a little and then began to blush. He was being nice to her, unlike her sister. She was already naked too, so how much more could he see. Slowly she parted her legs a few inches and then he thanked her. “Welcome” she muttered instinctively. As embarrassed as she was, it felt good when he slid his finger down her slit. He did it again and hit something strange making her jump.

“Did that hurt?” Linda asked.

“No, just felt funny,” blushed Tess.

“Uh oh...” Linda sighed as she frowned. “Jeff, you better look closer. Open your legs wider, Tess.”

Not sure what was going on she did as she was asked. As he had done to Linda the night before, Jeff used two fingers to open Tess's pussy and studied its inside. Tess turned bright red with embarrassment, but didn't protest. “I see what you mean...” he muttered.

“What's wrong?” Tess questioned.

“Do you remember when I went into the hospital two years ago?” Tess nodded. “I had that same problem,” Linda told her.

“I thought you had your appendix out? I didn't hear about anything else,” questioned Tess.

“Do you think I wanted people to know, stupid? We better take your temperature.” Linda suggested as she left the room, returning shortly with a thermometer. “Roll over,” she commanded.

“Huh?” gasped Tess.

“How do you think they do it in the hospital, stupid.” snapped Linda.

“I'm not letting you take it that way!” refused Tess.

“No problem. When mom gets home we'll just tell her you have the same thing I did. You can go to the hospital. They put you in a room – with NO DOOR and even a big window – take all your clothes off, have a bunch of people walking in and out, and they can take your temperature 'that way',” challenged Linda.

Tess pondered for a moment and then asked, “Will it hurt?” Linda shook her head. “If I let you, do you promise not to tell mom?” Linda nodded. “OK then, but Jeff has to do it, not you. You'll make it hurt!”

“Deal,” Linda agreed as she handed the thermometer to a surprised Jeff. Tess hesitated until Linda reminded her of the agreement and then slowly rolled over burying her face in the pillow. Linda pulled her sister's ass cheeks apart exposing her quivering rosebud. “Just slide it in.” she whispered. Jeff had no clue how so he looked questionably at Linda. “Just push it in so about an inch is sticking out and then just hold it,” she again whispered.

Jeff had no idea three days ago he would get to see and do so much. He tentatively put the tip in the center of the pucker and gently pushed. To his surprise it slipped in easily. Tess didn't move at all. He watched in amazement as the little glass rod went into Tess. Linda mouthed OK and he stopped pushing. His hand rested on Tess's ass, she stayed motionless, and his cock strained against his pants.

Tess wanted to die of embarrassment. Her sister was holding her apart and something was being stuck inside “there” while they looked at her. At least it didn't hurt but that didn't help much if at all; she could still feel it. Her only hope was they could fix whatever was wrong. It would be far worse to have this happening in front of a bunch of strange people with others walking by and looking at her. Tess breathed a sigh of relief as she felt the thermometer being pulled out.

“OK, all done there. Now roll back over and open your legs. This was the part I liked,” Linda grinned.

“What are you going to do now?” Tess shuddered.

“It just needs to be rubbed. You'll like it,” answered Linda. She turned to Jeff and whispered, “Ever rub a girl? Now is your chance. Make it good, She'll love it!” Jeff smiled.

“All the bad parts are over,” Jeff announced as Tess rolled onto her back and opened her legs a few inches again. Jeff reached his hand between her legs and pushed on the inside of her thigh with the other hand trying to get more room. “Open up more... like you did before.” Reluctantly she spread a little more, thankful they weren't looking like they were before and his hand did cover her she rationalized. Tess pulled the pillow over her face in an attempt to hide as Jeff slowly began rubbing her pussy. Surprisingly it did feel good. She might have enjoyed the rubbing if she wasn't so embarrassed. Jeff continued to rub for a while causing some strange, but pleasurable feelings for Tess. Suddenly he stopped.

“You're all set now. You can get dressed,” Jeff told her.

“...but you'll need another treatment tomorrow, right Jeff?” Linda added and Jeff nodded.

Tess was glad her treatment was over, but sort of liked the last part even if she was naked. “OK.” she sighed as she put her clothes back on. She looked at Linda. “You're not going to tell mom what's wrong, right?”

“Nope, as long as you follow doctor's orders.”
