Jeff opened his door to look at the sex doll lying in the hallway. Yep, it still looked like his sister. That
was Chelsea's face, and her mouth was open. Usually she was yelling at him, but this time she was waiting
passively to receive a cock. And that was definitely her figure. Though he hadn't seen her naked since they
were both small and she had a washboard chest, he'd seen her dolled up (no pun intended) for her dates, or in a
bathing suit out catching some rays in the back yard. That was his sister's shape.
"Well, Chelsea," Jeff said, picking her up. "I keep seeing you dressed up as some college boy's fuck toy. Now
you've become the real thing."
He carried his doll sister into his room, careful to close the door behind him, and sat down on the edge of his
bed, setting the Chelsea doll on his lap. He locked his hands behind her waist and held her gently. Though this
was the latex blow-up version of his sister, she still had a great figure. He felt himself getting hard in his
jeans.
"I know you can hear me, Chelsea. I know your mind still exists in this inanimate toy. I'll give you just enough
freedom of movement to nod or shake your head when I ask you a yes-or-know question. Okay?"
The Chelsea doll nodded.
"Good. So. Do you know you're an attractive young lady? I mean it. Do you know you have a great face and
killer figure?"
She nodded again.
"And do you deliberately wear those form-fitting tank tops and sheath dresses so men will notice your body?"
She nodded.
"Do you wear them around the house so I'll notice?"
The Chelsea doll paused for several seconds before shaking her head no.
"Why the long pause? You're lying to me, aren't you? You're embarrassed to admit you want to make your brother
horny."
Again with the long pause. Then she nodded.
Jeff laughed. "Do you want to have sex with me?"
No pause this time: she shook her head no, quite emphatically.
"You want me to notice your body, but you don't want to have sex with me. So you're just playing a game. Is
that right? You're just teasing your brother so he gets horny and frustrated and you refuse to do anything
about it. Is that what you're doing?"
The doll nodded, but slowly and feebly, like she was ashamed. Well, Jeff thought, she should be.
"Well, you know what, Chelsea? Your brother has noticed your body. I think all brothers notice their sisters'
bodies, and they just learn to ignore the feelings they feel. But I have a unique situation here. Not only
are you completely helpless in your brother's arms, but your physical form now exists as a sperm receptacle.
Have you ever let one of your boyfriends cum into you unprotected?"
Chelsea shook her head no, again emphatically. Almost angrily.
"Well, I'm going to..." Jeff paused. "Have you had sex with all those college men I see you dating?"
Slower this time, she shook her head no.
"Are you... Chelsea, are you a virgin?"
Pause. Then she nodded.
Jeff smiled. "What luck. So am I. Well then, I guess we'll find out what it's like together. Because I'm going
to get myself up in that body you didn't want me to touch. Do you like that idea?"
Chelsea shook her head.
"Too bad, sister. Because you're going to take me all the way to heaven."
Jeff laid his doll sister gently on his bed, then stripped down to his boxer shorts and lay down next to her.
When he reached up to gently cup and stroke Chelsea's cheek, she began to shake her head no. But Jeff ignored
her. He traced his hand down her neck, caressed his sister's shoulder, then cupped his hand over his sister's
latex breast.
"Can you feel what I'm doing to you now, Chelsea?"
His sister nodded.
"I wonder if rubber sex dolls have a cherry. It's too bad your nipples can't get hard in my hand. You're so
pretty, Chelsea. You're so slim and sexy, and you have a great body. I wonder if Mom and Dad had a son and
daughter so we could share each other's bodies. Well, whatever. I want you to be my first."
Jeff kicked off his boxers, and straddled his doll sister. "Are you ready to lose your virginity, Chelsea?"
She shook her head no, but Jeff leaned down and kissed her cheek. "I'll be gentle," he said, as he lined his
cock up with his sister's opening.
Chelsea shook her head harder as Jeff rubbed his cock along his sister's slit, and harder still when he
pushed the head up inside her.
"Oh, Chelsea," he moaned. "You feel so tight."
Chelsea shook her head no, but that was the only movement she could make as her brother pushed all the way up
inside her. He paused for a moment, then began moving in and out, in and out. He started slow, but picked up
the pace. Chelsea finally gave up her useless mute protest and lay beneath Jeff as brother and sister lost
their virginity at the same time.
Jeff wasn't mean or rough. He kissed his sister's cheeks, her eyes, her shoulders. He took his time, making
love to his helpless, unwilling sister. Even he was surprised, since it was his first time, how long he
lasted. But after four minutes, he couldn't pace himself any longer.
"Chelsea," he breathed. "Oh. Chelsea. I'm coming. Ah. I'm coming inside you. Oh. I love you. Ah. I'm coming
in my sister. Oh. Oh. I love you. Ah. Chelsea. Oh."
And all at once, it felt like quarts and quarts of sperm jetted out of Jeff's body and into his helpless latex
sister. He arched his back as he filled Chelsea's womb with his lustful incestuous seed. His orgasm went on
and on. It felt like it would never stop. And he never wanted it to stop.
But finally it did. He collapsed onto his sister, his cock still pressed up into her latex womb, keeping his
seed trapped inside her. He kissed her cheeks and petted her breasts. "You were worth it, Chelsea," he
whispered.
After several long minutes, Jeff rolled off his latex sister and lay beside her. He continued stroking her
body—her breasts, her belly, hips and thighs. Brother and sister, naked in his bed, side by side.
"Do you love me, Chelsea?"
She shook her head.
"Do you hate me?"
She nodded.
"I'm sorry you feel that way, Chelsea. I am. Because I love you so much right now. You're the most important
woman in the world to me. I want to make love to you five times every day, because I love you, and I'm
attracted to you. You're my sister-lover, Chelsea, and I love you. Do you think you could ever love me?"
Chelsea shook her head.
"Well, I won't force you to fall in love with me, Chelsea, even though I could. I love you too much to take
away your free will. But I want to show you how much your brother loves you. And to do that, I'm going to use
my transforming powers to make you..."
