Marcy waited until Erika's mom had left the house.
She wore no bra, her last one had snapped during her last growth spurt. Her nipples ached too much anyway.
Her engorged tits pressed their weight into the green knitting of her sweater. Buttons ran up the length of the material that she had to unbutton to allow her 'girls' to breath. The growing gap in her cleavage was visible for all who might be looking. Her darkened nipples pushed into the fabric, she needs band-aids to stop them itchy and chaffing. Her paunch was starting to push its way into the loose fabric around her waist.
Her black hair was down loose, knotted and she looked like she had just woken up or she needed a good night's sleep. Marcy's face looked puffy and swollen, just like her tits and belly. Hollow eyed she looked on from behind the bushes of a foreclosed house. The bushes and lawn were dying but she knew what had caused Nathan to fuck her was inside that house. He was still at college and as gay as ever, the thing that had fucked her was inside the house. Erika's mom Lily had left the throbbing in her clit was still there. So it must somehow be Erika.
Erika had stolen Marcy's panties. It was all she needed. She now sat in those used panties looking at Marcy's body. Her perky, symmetrical B cup tits pointed in the same direction. Erika had these panties before fucking the real thing as Nathan. She had wanted to figure out how to please and seduce Marcy by using an exact copy of her body. She had an ass that wouldn't quit, it wasn't a big butt but more like a bubble butt. Long legs shaped by swimming. Her olive skin showed she was of Italian descent.
She mad various poses using this body, she was lithe and graceful like a sexy panther. Erika knew she owned a couple of cats somewhere. She bent her spin thrust these glorious tits nude and proud into the air. She didn't have any tattoos or scars which was interesting to Erika, who didn't like tattoos? As she was looking at the body she had had sex in and then fucked the real thing she heard a knock at the door. Erika considered changing back into her normal shape or maybe Nathan but she wasn't that dumb.
Marcy looked as the door swung open and she sees an empty house.
She walks in looking at the furniture as a pair of hands, her hands, grab her by the tits. She stumbles back as she feels these hands touching her, she goes moist. Marcy leans in against the body, her body, feeling what she wants a lover's touch. She whips around and sees her own face staring back at her. She doesn't care she kisses her clone as her clone rips open the studs on her sweater exposing her swollen tits and belly.
Erika unleashes a flurry of kisses to Marcy's tits and belly, she is already showing she's knocked up. Marcy's head is thrown back as she moans with pleasure. Her clone pushed her until she stumbled on to the floor. She was topless now that her sweater had been taken off. Erika unbuttoned her jeans and started to lick her pussy.
Marcy jerked the first time she was kissed, then the second. Erika, she presumed, was doing her just right. A grin slowly spread across her face as she closed her eyes in pleasure as she felt a pinch her left breast. Marcy started to lose herself in her climaxing orgasm. She started writhing with pleasure and she lost connection to reality and why she was here as her pleasure built. Her heart started beating faster, her breathing became shallow as she started to feel it. She started licking her lips as she twisted her head to the side in pleasure.
"Oh" she gasped as she came.
Erika, still a clone of Marcy's body, pulled herself up the length of Marcy's body. They kissed for a bit as Marcy's breathing got heavier. Marcy felt the weight of her clone lift as the hand hovered near her vagina. Her eyes were wide. This was a true clone of her body right down to the mole on her right breast.
"OH!" she moaned.
Erika had just stuck her long middle finger into Marcy's wet pussy lips. She knew how to fuck this girl as she has masturbated this body herself. Marcy moaned as she gripped her lover around the chest. As she looked down she saw her own, prepregnancy, tits that she knew so well encased in a white crop top that she had found was missing when Nathan (operated by Erika had) had fucked her so properly. She was exhausted and just fell asleep on the sexy mess of the floor.
