Insatiable
In the end, you are a bit disappointed your sister is on the bed recovering, but you could still go a few more rounds. It’s not about the skill. It doesn’t up your stamina or anything. You hear your phone ringing and go collect it in the kitchen. It’s Merry.
“Mom, it’s lunchtime,” she says.
“I’m with your aunt. You should practice making your own lunch,” you explain.
There is a quiet pause. “alright,” Comes through the phone.
You think for a second and tell your daughter, “Tell Tiffany too.”
“I can cook!” she harumphs.
“It’s not that, honey. You might not be together in the future. You both need practice,” you soothe.
“I guess your right. Bye,” she quickly says. Before you can say bye back, Merry’s already hung up.
You return to your sister’s room with a sigh. As you enter, Olivia is struggling to sit up.
“You ready for another round?” you ask with a leering smile.
Olivia looks at you with her mouth agape. “Seriously? I just had two massive orgasms.”
You look at her, not understanding. You both stare at each other for what seems like minutes. She swallows hard and tentatively asks, “You’re serious?”
You nod. “Of course, I’m ready for more,” you say, flopping onto your sister.
“I’ll die,” Olivia complains.
“You’re exaggerating,” you say, and you give Olivia a peck on her forehead.
“It’s too painful. If it was a normal orgasm, I might be fine. But those two orgasms destroyed me. My muscles are still spasming.”
“When I masturbate, I have three big orgasms in the morning and three after lunch. How can you only handle this?” You argue with consternation.
“No way!” Olivia shouts with her hands covering her mouth. “That’s crazy. You are a beast. We’ll need the whole family to satisfy you.”
You are completely confused. Is your sex drive not normal? You never watched porn or checked the web. You did have basic sex ed, but it didn’t touch on how often people can orgasm.
Olivia looks up at you. Your faces are still close as she says, “Perhaps that’s a prerequisite to get the KDK app? Porn stars would be jealous of your natural talent.”
“Maybe, but I’m not satisfied,” you say as you flop your face into the bed.
You feel a hand reach between your legs and massage your wet lips. “I might be tapped out, but I can help still help you,” Olivia says.
Well, that’s what she said, but after an hour, she fell asleep from exhaustion while you still have energy. “Well, it scratched the itch, I guess,” you mumble as you lie beside your sister.
In the end, you cover Olivia up with a blanket. You kiss her cheek and head home.
Author (Sorry for the short chapter after returning. Things got a bit out of hand and I was bouncing between not releasing or just putting out what I have. It's late so I'll be going to bed. Standard release for tuesday.)
