Francine

My sister's friend, Francine, was in the doorway. Her eyes were wide and her mouth was open in shock.
I always thought she was cute; curly black hair, brown eyes, soft curves. But right now...she scared me. We were caught!
"It's not what you think, Fran!" Jane said, standing up.
Francine blinked, "Then...WHAT were you doing?"
"I thought John could use a crash course on Sex Ed...and we are siblings, yes, but he was VERY professional."
Francine looked at me, then Jane and after a few silent minutes she said, " 'Sex Ed', huh?"
I nod. It wasn't a total lie...I WAS taking a health class. "By the way, what are you doing up here?"
She came into the playhouse, hands on hips. "Chris and Janet passed out from those sleeping pills I put in their water bottles...well Chris anyways. Janet fell onto her bed from eating all that sugar."
"Why'd you do that?" Jane asked.
Her friend shrugged. "Chris was starting to annoy me...with her horror movie talk." She paused. "Ok, I won't tell the others...on one condition."
I closed my eyes, of course...
"Yeah?" Jane asked.
"John examines me next."
Jane and I look at each other, then we both nod.
As my sister gets dressed and Francine undresses...I pray to God that this was the last time. Jane plays the nurse as I have Francine sit on the bed.
"What brings you in, today?" Jane asks.
"Just a routine check up." Came her answer.
I start by listening to her heart and lungs; then feeling her breast like I did with Jane. After feeling no lumps, I feel her neck and have Francine open her mouth while I shine the light to see into her oral cavity. "Say 'ahh'."
"Ahh~"
I watch her uvula move as she said it.
Once I saw her mouth I looked at her eyes and ears then had Francine open her legs. Taking up the 'bird-beak' again, I inserted it before opening her up. It was pink like Jane's.
"How do I look?" She asked, coyly.
"Healthy." I say, while touching her womb.
"Uh, Fran?"
"Yeah, Jane?"
My sister blushed before asking, "You don't have your hymen?"
"Nope." Francine replied. "My ex-boyfriend and I...got into it...before we broke up last year."
I blinked, confused. "What are you talking about?"
"When your hymen's broken...it means you're no longer a virgin."
My face went scarlet. "Oh."
Jane removed the 'bird-beak' and I felt inside with one finger. Francine moaned and moved her hips so my finger went deeper inside of her. There were no lumps.
As I removed my finger from her inner folds, Francine looked at me with clouded eyes. "Please..."
"'Please' what?" I asked.
"Please...stick it in me..."
Jane shook her head. "No Fran, he's not sticking his member in you."
I nearly fainted at that.
"But I'm so close, Jan!" She moaned. "Please!"
She looked at me, and I sighed. "We can't leave her like this."
"I know but...fine. But..." she looks at her friend. "Only a Blowjob, got it?"
"Deal."
Jane left to get one from Francine's purse, while I began to clean up the tools. Francine sat up and whimpered, begging me to take her now. Just when I felt like I was gonna break...Jane came back. I unzipped my jeans and pulled out my member before slipping on the condom. Francine then took me in her mouth.
Jane said to go slow, Francine obeyed. Moving her head up and down my member; I could felt it hit the back of her throat and her tongue coil around my member as if it was a Lollipop. I heard her moan as I soon made her cum...me as well.
We both clean up, me myself and Jane cleaned her friend.
"Next time, we'll use her dilio...I saw it in her suitcase." Jane said, while helping her friend up.
"That was...weird." I confessed. "I...I don't want to do it again."

I really didn't.

"I'm sorry, John." Francine said. "When I get...lustful...I can't control myself."

I waved it off and, once Francine was dressed, we went down stairs. Just as the family car pulled up to the house.
