My sister softly whispered, “Yes.”
When we got out of the hot tub my sister and my wife dried each other off with towels. Then they both dried me. We walked into our marital bedroom. My sister lay on our bed, spreading her legs. My wife’s tongue licked against my sister’s clitoris. My sister responded by tightly grasping the blanket on our bed.
My wife separated my sister’s labia and said to me, “Look, your sister is still a virgin.”
“Of course I am,” my sister said.
When my wife began to blow gently on my sister’s hymen my sister’s face wore an expression of ecstasy. Finally, she looked at my erect penis and said, “Get inside of me.”
My wife got a towel, and said, “You will bleed a little. This will catch your virginal blood.”
I said, “I will put a condom on.”
My sister said, “You don’t need to. Before I came here Mom got me a prescription for birth control pills. She told me she did not want me to have sex, but that if I did she did not want me to get pregnant. She saw how we looked at each other last Christmas. She knew that when I came here for the summer we would probably be doing this.”
“Does Dad suspect anything?” I asked.
“There are things he does not want to know about. I think Mom and Dad understand that because we did not grow up together we do not feel the way about each other most brothers and sisters feel.”
“Before you guys begin, may I take some photos?” my wife asked.
“Yes,” my sister answered.
My wife produced a camera. “First I want a full frontal of you.” My sister stood facing my wife, and smiling. “That’s excellent,” my wife said as she took a photograph. “Now turn around.” When my sister did, my wife said, “You look good from behind too.”
“Thank you.”
“Put your hands on your waist, turn your head around, and smile at me.” My sister did. “Beautiful. Not it’s time to begin.”
My sister lay flatly on the bed, with her legs straight. “That makes his entry more difficult,” my wife said. “Wrap your legs around his body.”
When she did, I began my assault on the fortress of my sister’s virginity. Although my sister was thoroughly aroused, her hymen was a formidable sentry. I was hurting my sister, and asked, “Are you sure you want me to do this?”
“I have wanted this since Easter. Keep pushing.”
I did. When I broke my sisters’ hymen she gave a soft expression of pain that my wife captured with the camera. I pushed my stout explorer deeply into virgin territory where no man or boy had gone before. My wife put aside the camera, and lay next to us. She kissed both of us on the lips, held my sister’s hand gently, kissing it, and offering us words of encouragement. “You are doing beautifully,” she told my sister. Your brother is an expert instructor.”
When my wife could tell that my sister was about to have her first vaginal orgasm, she took a photograph of my sister’s rapturous face.
My sister’s vagina was even tighter than my wife’s was on our wedding night, so my coital movements were slow and gentle. Finally, my wife captured a photograph of my face’s triumphant expression as I filled my sister’s vagina with my life’s fluid.
My sister held me tightly with her arms and legs saying, “Please don’t leave yet. This moment is precious to me. Thank you. Thank you so much. I always wanted my first time to be perfect. This is. This is the best birthday I have ever had.”
When I finally withdrew from my sister my wife told her, “Keep your thighs spread. Sit up on the bed, bracing your back with your arms.” When my sister did, my wife took a photo of her vagina leaking her blood and my semen. My sister’s face wore an expression of pride and sexual fulfillment.
My wife left the room, quickly returning with a bottle of champagne and three champagne glasses. She opened the bottle, filled the glasses, and gave them to us.
“What is this for?” my sister asked.
“We are celebrating your seduction. We planned this last Christmas lying in bed together.”
“My seduction?” my sister asked. “I thought I was the seductress. I wanted to have sex with each of you, but I was afraid it would damage your marriage.”
“Since you have come into our lives our marriage has become more exciting,” my wife said. “Your brother can make love to one of us. Then we can pleasure each other. When he becomes hard again he can enjoy the other of us. The most he has done with me is four times in a single night. Let’s see if we can inspire him to do more.”
“My sister laughed pleasantly, and said, “Other girls can fumble in the back seats of cars with boys who don’t love them. I am having an affair with my married brother and his wife. I feel loved, desired, terribly sophisticated, and delightfully naughty.”
