"Okay, now smaller," Emma said. "Really small. Not little cones, but broad, flat, low to your chest. Yes, like that. Beautiful." She was running her palms over Jessica's breasts, and the breasts were changing shape as she spoke. "Beautiful, just beautiful," she whispered, smiling delightedly. "These are wonderful." She grabbed a nipple between her thumb and knuckle, pulling hard and letting the flesh snap back. "Oh, yum." She dipped her head and closed her mouth around the nipple.

Jessica laughed, first hugging Emma's head to her chest, then nudging her away. "C'mon, back up and look at me. Watch what I can do with this thing. Tell me what you want. Wider hips? Narrower? More muscle? More fat? I can even change my height five centimeters either way. Whatever you want, baby, just ask." She was naked, standing against the bedroom wall. She held her arms out to her sides, displaying herself.

Emma grinned, putting her knuckle to her mouth. "More hip," she said, and then giggled as she watched the change. "Wow. It's amazing. I've never seen a modder body up close before. I was afraid you wouldn't look...real, but you do. You look and feel just as real as ever." She stroked her hand down Jessica's hip.

"Oh, I'm still real baby, believe me." Jessica reached up and pulled hard on her own left nipple, mimicking what Emma had done a moment ago. "I'm still real skin and blood and muscle and bone and fat, only now there are a bunch of busy little nanobots in there, moving things around, switching cells in and out of collapsed nascent states, following orders from my cortical implants, and blah, blah, blah."

"What's it feel like?"

"It's an amazing turn-on, every time I change something. I'm practically dripping here. They said that would happen, but it's purely a psychological effect. Modding just makes you ultra-aware of your body, and that makes you horny."

"And everything still works? All the little nerve endings and everything?"

"Oooh, yeah," Jessica said, her voice low and almost singing the words. "They make you come as part of the post-insertion examination. Twice -- once as female and once male."

"Fuck," Emma said reverentially, and then she looked disappointed. "So you've already come with a cock? I was kind of hoping it would be me that gave you your first boy-orgasm."

"You'll be my first fuck, sweetheart. My boy-cherry is all yours. And just wait 'til you see my cock. As big as you want -- well, within reason," she added giggling. "Thick or thin, long or short. Whatever my sweetie wants, I can give it to her." She thrust her pelvis forward with the word "give," laughing again. Then she pulled Emma to her and they kissed, moaning and clutching at each other.

Emma pulled back enough to look at Jessica's face. "You changed your face a bit, didn't you? You have a little more cheekbone."

"Just a bit. I can change it back if you want."

"No, it's fine." They kissed again.

"Take your clothes off," Jessica said.

Naked, Emma knelt at Jessica's feet. She leaned her face close to her lover's sex and reached her hand up to touch it. "Ah, here's a part of you I recognize." She ran her fingers down the triangle of curly brown hair, then slid the tip of her forefinger between the outer lips, nudging them apart slightly. "Looks the same, feels the same, even smells the same." She pushed her finger in as deep as it would go. "You are dripping, you horny slut," She chuckled. She pulled her finger out and sucked on it. "Mmm, yeah, that's my Jessie." She leaned in, pressing her mouth against Jessica's cunt and extending her tongue to lick the wet folds and push up between them. Jessica closed her hand in Emma's hair and moved her feet apart, spreading her legs. "You want to see my cock now?"

At first Emma seemed not to hear. Then she jerked her head back and cupped her hand over Jessica's sex. "No! Um...no, not yet, sweetie. Let's play around with you like this for a while first." She took Jessica's arm and pulled her toward the bed. "I love your tits like this."

They lay on the bed, embracing, fondling, stroking, sucking. Emma pushed two fingers into Jessica, then three. Jessica grabbed Emma's wrist with both hands and held it in place as she raised herself to her knees. "Emma," she gasped, "I need to come. I can't wait. I need it. Fuck me. Fuck my new cunt." Reaching between her legs she fumbled at Emma's hand, trying to force the remaining finger into herself while pulling up on Emma's wrist. "Fuck me. Fuck me with your hand. Put more inside me. I can take it. I can take a lot more into my cunt now."

Emma straightened her little finger, pushing it up between Jessica's cunt lips along with its three mates. Still Jessica pulled at Emma's wrist, gripping hard, her hand slipping on wet skin. She arched her head back, her eyes closed to slits. "More," she hissed. "Fuck me. Fuck your hand into me!" Emma's hand was buried in a clenching wetness up to the root of her thumb. She felt Jessica trying to fold her thumb against her palm, but she resisted, instead pressing her thumb against the outside of Jessica's cunt, sliding it side to side over the slippery clitoris.

Jessica suddenly groaned and hunched forward, making a long series of low grunts while rhythmically pulling up hard on Emma's wrist. Her eyes were open but focused on nothing as the cadence of her gasping cries gave way to one long, shivering moan. Finally her spasms subsided and she became still, sitting back on her haunches and smiling down at Emma. "You should have fisted me," she said. She patted a hand against the thatch of her pubic hair. "I can take it now. I could take a bigger fist in there than your dainty little paw, no problem."

Emma eased her hand out of her lover's cunt. "I was afraid I'd hurt you."

Jessica dropped to her side on the bed, then rolled onto her back. "Don't worry, baby. This body is amazing; practically nothing hurts it." She sighed, smiling up at the ceiling. "God, I love this! I feel like I could do anything. I could fuck anyone; make any man or woman frantic to have me, just by modding myself into whatever their favorite dream-fuck looks like."

Jessica rolled over on top of Emma, taking a breast into her mouth and reaching up to caress her lover's face. She worked methodically, sucking on each breast, teasing each nipple with her tongue, sliding herself down until her mouth was at Emma's pussy, dipping down to lick, very lightly at first, then deeper, then closing her lips around the swollen clit, sucking on it and pressing her flicking tongue against it. Eventually she raised her head, smiling and wiping her wet face in the crook of her arm. "Can I fuck you now, baby? I want to fuck you with my new cock."

"Okay."

Jessica sat back on her heels, looking down at her own belly and crotch. "All right Emma baby, watch this!"

Emma watched, holding herself up on her elbows. "Wow," she whispered. Her eyes were wide, her lips trembling slightly. She looked up at Jessica's face. "Wait, Jessie," she said when Jessica started to shift herself forward. "Sweetheart... can you make the rest of your body like a man's?"

"Yeah, good idea! Wait 'til you see this -- just give me a minute."

Jessica's face went blank with concentration. Her breasts shrank, her hips narrowed. Hair curled out of the skin over her chest and stomach, and more sparsely, her arms and legs. Her skin looked coarser, and rippled over lean muscle as subcutaneous fat disappeared. She grinned down at Emma and rubbed her hand over her own face. The stubble of a beard made a faint scratching sound. "How do you like boy-Jessica?" she asked, her voice deep and masculine.

"W-wow." Emma reached her hand to Jessica's hard-muscled chest, brushing the hairs with her fingertips as she slid across to a thick upper arm and its bulging bicep. "Holy crap, Jessie..." Her hand went back to Jessica's torso, tracing a line down her stomach, then lower. She closed her hand around the hard cock that jutted out of Jessica's now-coarser pubic hair. "Amazing," she whispered, working her hand back and forward over the length of cock.

Jessica closed her eyes and tipped her head back. "Jesus, your hand feels good there," she said.

The two of them stayed in this position for a while, Emma stroking Jessica's cock as Jessica sat with her hands on her thighs, breathing heavily. Finally Jessica put her hand over Emma's, stopping her. "Daddy needs some pussy now, baby," she said. "What do you say we stick this thing someplace nice and warm and wet?" She started to lean forward over Emma.

"Wait, honey..." Emma said. "I just thought of something. What if..." she hesitated. "What if you're fucking me and...you start making it bigger while it's inside me? Without really meaning to... just because you're caught up in the feeling and you keep wanting to go deeper?"

Jessica held her hand up in a shushing gesture. "Don't worry, sweetie. They told me that's controlled against. The nanobots won't change any part of me while it's in contact with another body. Clever, eh? They think of everything."

"Okay...but, that's already a pretty big piece you're packing there, girl." Emma pointed a finger at the phallus whose head was aimed between her legs. "I'm not sure I can take all that. Could you make it a little smaller, a little less...fat?"

"Baby, in the first place, I've watched you fuck men a lot bigger than this. And secondly, this is the exact size of your favorite toy. Girth and length, down to the millimeter."

"Really? Okay...but go easy, huh?"

Jessica tilted her head back and laughed. "Did you just say 'be gentle with me, Jessica?' Is that what you just said?" She laughed some more, and then leaned forward suddenly, grabbing Emma's wrists and pinning them back to the bed. "Maybe I don't want to go easy on you, Em," she growled in her heavy, male voice. "Maybe I want to ram your cunt like a piledriver. Maybe I want to pound you like a piece of meat." She laughed again. "Or maybe I don't want to fuck you at all. Maybe I'll just get up from this bed and..." As she was saying these words, the head of her cock slipped between Emma's wet pussy lips.

Jessica raised her eyebrows in an exaggerated expression of surprise as she looked down at the place where her crotch was easing toward Emma's. "Oops! Look at that! I guess I am going to fuck you!" She lowered her head to kiss Emma's lips as she flexed her pelvis to drive her cock in. Emma whimpered into Jessica's mouth. Jessica lifted her head again, holding her torso up on straightened arms, arching her back and neck and looking up toward the ceiling, away from Emma's face. "Oh god!" she gasped. "Oh god, girl, I'm fucking you! I'm finally really fucking you! Fucking your sweet cunt, your sweet cunt." She raised and dropped her hips, her hands still holding Emma's wrists to the bed. She let her head fall forward, her eyes half-closed, her mouth lolling open. She looked down at her cock, watching it drive in and out of Emma, watching the slick wet flesh slapping together and sliding apart. "Your cunt feels so good...it feels so good on my cock. I can feel it holding me, gripping me..."

Her eyes drifted to her own thick, bulging arms, her hard, flat chest, the muscles of her stomach that flexed to drive her cock into the cunt she was fucking. "I'm gonna come, baby. I can feel it...I can feel my balls...gonna shoot my come into you...it's so...fucking...amaz--" Her words choked off then, as she made a strangled, animalistic grunt and drove herself into Emma with a final, convulsive thrust. Her arms buckled and she dropped her weight onto Emma's body. With shuddering moans she rode the pulsing waves of her orgasm, her body twitching as it pumped out its rhythmic jets of semen.

Minutes later, Jessica rolled off of Emma, settling on her back with a throaty sigh. "There you go, sweetie," she chuckled. "You got my boy-cherry." She twisted onto her side and put her hand to Emma's pussy. She pushed two fingers in and took them out, slick with come. Then she reached up to Emma's face and drew the two fingers down the length of her nose, painting a lumpy stripe of fluid there. "See that?" she laughed. "I fucked you. I shot my load into you, I fucked your cunt. I fucked my little Emma's cunt." Lying on her back again, she threw her arms up above her head. "Wooo-weeee!" she cheered. "I love this! I love this body!"

Emma wiped the come off her face with a corner of the bed sheet, rubbing hard at her nose, then taking a clean part of the sheet and wiping her whole face. She swung her legs over the side of the bed and sat up, facing away from Jessica.

Jessica reached out a hand and touched Emma's back. "How're you doing baby?"

"I'm fine."

"You want me to change back to girl-Jessica now?"

Emma stood up. Her body wavered for a moment as if she was dizzy. She took a few steps and put her hand to the wall. Her back was still to Jessica and the bed. "No," she said, not turning around. "I think you should stay like that. It suits you."
