Connie
They were lying on Connie’s bed killing time, the afternoon slow and unhurried around them, when Serena rolled onto her side and propped her head on her hand with the expression she wore when something had been sitting in her mind for a while.
“How old were you when you first kissed a boy?” she said.
“Fourteen,” Connie said.
“Fourteen!” Serena stared at her. “Who?”
“Vincent Song. He pulled me into the broom closet at church.”
“My God, he’s such a hunk.”
“He’s a looker,” Connie agreed. “But he about choked me to death ramming his tongue down my throat. Mom asked later why I was talking funny. I told her I choked on a chicken nugget at the noon meal.” She paused. “Good looking. Terrible kisser.”
Serena was grinning.
“I didn’t get to kiss another boy until university,” Connie said. “You know Mom — it’s a wonder she didn’t have us both in chastity belts on a dog leash.” She looked at her sister. “Mom told me you’ve never been kissed. How come? You’re a really pretty girl. You’ve got a cute figure.”
Serena looked at the ceiling. “Too scared. Class bookworm. Too boring.”
“You are not boring.”
Serena shrugged in the particular way that meant she’d been telling herself something long enough that arguing with it felt like too much work.
Connie let it sit for a moment. Then she said, “Hey. After dinner tonight — we need to talk about some serious stuff.”
“Like what?”
“Like you getting into my panties.”
Serena’s head came off the pillow. “Me? I thought you were in the driver’s seat.”
“That’s what we need to talk about,” Connie said.
Just then Margaret’s voice came through the intercom from the kitchen, even and unhurried, calling them down to dinner.
Margaret commented at dinner that Serena had a lot more color lately. She said it looking at her younger daughter’s face with the careful measuring look she’d had since the diagnosis, but this time there was something lighter underneath it. Something almost like relief.
Bill was nearly finished with his meal when he set his chopsticks on the corner of his plate and looked across the table.
“Have you two done anything together yet?” he said.
The table went quiet.
Connie turned to look at her father. “Done what, Dad?”
“You know.” He kept his eyes on his plate. “Bedroom stuff.”
Connie looked at him for a moment. Then she said, “Yeah Dad, we have. I’m trying like hell to get her pregnant but I think my sperm count is too low.”
Bill’s face arranged itself into something smug and closed. He set his napkin on the table, pushed back his chair, and left the room without another word.
Margaret covered her face with both hands and shook her head slowly.
Serena pressed both hands over her mouth. Her shoulders were shaking.
Connie looked at her mother. “Need help with the dishes?”
“No thank you, Sweetie,” Margaret said into her hands. “I think you’ve helped enough.”
The sisters smiled at each other and took their plates to the sink and headed upstairs.
Serena’s room was quiet and lamp-lit, the house settling into its evening sounds around them. Connie got on the bed and scooted to make room. Serena lay down on her back beside her and immediately dissolved into laughter.
“I cannot believe you said that to Dad.”
“He was rude and insensitive,” Connie said. “It was completely uncalled for.” She turned onto her side, propped her head on her elbow and looked down at her sister. “Enough about Dad.”
Serena’s laughter settled. She looked up at Connie and waited.
“I want to talk about where I am and what I’m feeling,” Connie said. “I want to talk about where you are and what you’re feeling. And I want to talk about what’s next. Because once we start deep kissing our relationship is going to start changing from girlfriends to lovers. Quickly.”
Serena nodded slowly.
“We’re both heterosexual,” Connie said. “We’re sisters. We are in foreign territory mentally and emotionally and I think we should both be honest about that rather than pretend otherwise.” She paused, finding the words she’d been turning over for days. “You told Mom you wanted to experience an intimate relationship with someone who loves and cares deeply for you. If you’d simply said you wanted sex we wouldn’t be having this conversation. What you were asking for was a mate. A significant other. A spouse.” She looked at Serena steadily. “I’m not attracted to girls. But I love you enough to be attracted to you for the right reasons. In order to tell you I would be your lover I had to, in my own mind, marry you. Mentally and emotionally. I needed to become that person for you before I could offer to be that person for you.”
Serena was very still, listening with her whole body the way she did when something mattered.
“Relationships progress in a natural order,” Connie continued. “Holding hands. An arm around a shoulder. Kissing. Petting. The actual act. And I want to be clear about something — some people tell themselves that bringing someone to orgasm digitally or orally isn’t sex. It is. Plain and simple. I won’t lie to either of us about what we’re doing.”
“I know,” Serena said quietly.
“We’ve naturally gravitated to me being the more aggressive one and you in the more receptive one. Which means right now I feel like a teenage boy who doesn’t know when to move to the next step.” She smiled slightly. “Which is honestly a little funny.”
Serena smiled back. A real one.
“So here’s what I propose,” Connie said. “A quid pro quo approach. I have already married you in my mind. Which means my body belongs to you. If you want to touch my breast — hold it, squeeze it — do it. I belong to you.” She held Serena’s gaze. “But if you touch my breast you’re telling me I can touch yours. If you put your hand between my legs I’m going to reciprocate. No ambiguity. No guessing. Is that clear and agreeable?”
“Yes,” Serena said. “I agree.”
“Good.” Connie settled back slightly. “Now let’s talk about experience. I started masturbating at fourteen. I’ve had oral and vaginal sex twice, same man both times. I’ve given and received oral sex.”
Serena listened without expression, just taking it in.
“I know you’re a virgin,” Connie said. “But have you had any contact at all? Kissing? Petting?”
“No. None. I’ve never been kissed by a boy or a girl.”
“Are you attracted to girls at all?”
Serena thought about it honestly. “Yes and no. There have been a couple of girls I wondered what it would be like to kiss. But I never went further than the thought.” She paused. “I tried masturbating a couple of times. I think I might have broken my hymen because I felt a twinge of pain and there was a little blood on my finger. I stopped and I haven’t tried since. I’ve never had an orgasm.” She looked at Connie. “I don’t know how to French kiss. But I know the basic mechanics of sex.”
“Have you ever caressed your breasts? Touched your nipples?”
“No.”
Connie looked at her sister. Eighteen years old. The novels on the nightstand. The whole architecture of romantic knowledge built entirely from other people’s stories.
“So you’re a complete virgin,” she said. “Sexually, entirely. I have to tell you, Sis — in this day and age it seems almost surreal. Like a fluke of nature.”
“I know,” Serena said, without self-pity.
Connie was quiet for a moment. Then she said, “Before we go any further I’d like to check you. See if your hymen is actually broken or just torn. I’d hate to assume it’s gone and cause you a lot of pain when the time comes.”
Serena considered this for a moment and then nodded. “Okay. I might as well get ready for bed anyway.”
She undressed and slipped on a thin sleep shirt, leaving her underwear off, and got on the bed on her back, pulling her ankles up toward her body and letting her legs fall open. She pulled her labia apart without ceremony, looking at the ceiling.
Connie turned her phone flashlight on and examined her carefully.
“You have a nearly intact fimbriated hymen,” she said.
“What does fimbriated mean?”
