Of course not!

John pulled his hand off his cock and groaned "mmmmmmmmph fuck! Your gonna make me cum" his cock kicking and spurting little jets of pre onto the plastic of the box. "Fuck!" John shouts realizing what he's done. The box was ruined now. Jessica was definitely gonna notice that...maybe if he wipes it off fast enough?

He reaches out and grabs the box, rubbing the pre cum off with his sisters panties. No use, dark splotches had formed at the bottom where it had dropped down. "Fuck it" he said to himself as he tore the lid off the box and grabbed the tiny graduate from inside. The dark gown soaking up his juices, soiling his sisters prize possession.

"Yay! I'm so happy you decided to play with me. Like I said my name's Gwendy what's yours?"

"Shut up" he said through gritted teeth as he knocked the cap off the dolls head and started pulling the gown off the doll.

"Well that's not very friendly mister! I just want to make you happy." The doll said in a pouty voice.

John pulled the clothes off the doll leaving her nude. Between her legs was the vague impression of pussy, a small crease between her thighs, but nothing graphic. Her soft champagne flute breasts bounced as he ran his thumb over them. She was soft...not hard plastic like the older models. "Fuck..." He felt his knees buckle for a second as his cock rose up and spit a little glob of pre onto the floor. He put the doll down on the desk and held her there with his thumb pressing into her belly, which gave slightly.

"You sure do curse a lot...and it wasn't very hospitable to take all my clothes off but if it makes you happy I don't mind" she said smiling up at the boy from under the tip of his cock. He had moved closer to the desk, jerking off over the doll. She studied his face, the processors in her mind running through thousands of images a second comparing them to him. Eyes closed, head back, mouth slightly open, penis erect, leaking seminal fluid...match, pleasure, erotic. Then videos and images, porn, porn, porn.

"Do you like beating off to me?" The doll asked in a bright valley girl voice. "You know I wasn't made for that...my, my creator? That's why I had to say all those rules. Do you like breaking rules?"

John groans and pushes his hand to the base of his cock and squeezes tight to stop himself from cumming "ooooh, oh fuck" he says leaning forward and propping himself up on the desk. His cock resting on the dolls torso, his head dribbling pre on her breasts. She pulls her hands back and her eyes go wide in surprise "Oh wow! Um mister do you...um. How can I help?"

"Wrap your arms and legs around it."

"Okay" the doll responds cheerily and does as he says. Her soft supple limbs wrapping around his considerable girth. The doll was maybe at most an inch or two taller then he was long so it was an easy fit.

"Squeeze it" he said nearly panting.

The doll did as it was commanded. John moaned as he felt the pressure increases around his shaft. She was pressing his underside against her soft little torso. He slowly rocked his hips back and forth fucking the doll.

"Fuck, Jessica."

"I'm not Jessica I'm gwendy silly!" The doll said as John's tip bumped off her nose, his head gliding past her body, his balls tickled by her feet.

"Yes you are...mmmm fuck tell me how big it is." Long strands of pre leaking from him and hanging between his tip in doll, getting in her hair, dripping off her body.

"It's huge mister...as big as I am and so wet." She said emphasizing the last word and giggling.

"Yes, god! Take it Jessica. Take your brother's cock. Fuck say my name Jessica."he groaned speeding up, his thighs slamming the desk as he fucked the doll.

"What is it?" The doll asked

"Fuck!" He said stopping for a second and gritting his teeth, feeling the edge slip away, the fantasy. "John" he said starting back up. His cock gliding up and down her body faster and faster. Her slit, thighs, soft breasts, and adorable face adding texture to the tight squeeze.

"Mmm okay John. Your thing is so hard! It's um, it's leaking like a lot" she said sounding a little concerned.

"Yes, fuck...say it again" he groaned and sped up.

"John" the doll said happily

"Yes, Jessica. Keep saying it"

"John" she said again giggling. The way he was rubbing on her was tickling and something funny was happening in her head...everything was so wet!

He slammed his hips forward hard. John shouted out in pleasure. His cock arched up shooting cum all over the desk. Big thick globs landing on the doll's head. She started to shake and twitch her voice box glitching and letting out a long jittering wail.

John stood there, unable to move, head back eyes closed in ecstasy...but when he felt the doll twitching he looked down. "Shit! Shit! Shit!" He quickly grabbed the panties again and wrapped her head in them trying desperately to remove the cum. Electronics and liquids, why didn't he think of that!

When he was done the doll laid there motionless.
