Lydia gives a sly grin and wraps her arm around her cocksleeve's back, picks her up, and carries her to the bedroom while still on her dick. She drops her on the bed and lifts one of her legs to use as leverage, fucker her harder. "I... AAAHHH... mmph, love it rough like this," Em moans up at her new dom. Lyd is getting close, and Em's moans get her going harder and faster than before. She doesn't know how much her little friend can hold, but it's not like she can hold back now. "Who knew you were such a dirty little slut?"
Em climaxes, fireworks going off in her head as she screams in pleasure. "Give it to me! All of it!" Her contracting pussy drives Lydia over the edge as well, and she spills the first wave of hot semen into Em's womb. The force of the first shot visibly jolts Em, causing her tits to bounce violently. Her eyes widen and she moans up at Lyd, begging her not to stop. Lydia strengthens her grip on Em's thigh and continues pumping jizz into her now slightly bloated belly.
"Take it all you little slut," she asserts. Em clenches again, causing several larger shots to blast out. Her belly bloats further, looking around mid pregnancy. Lydia rubs Em's poor, bloated gut as she fills it even more. Em orgasms again, her quivering pussy adding to her partner's once more. "C-cum," she manages between moans. Her stomach tightens, and her belly button finally pops out, inviting Lydia to play with it.
"P-please turn me over... smash me from behind like a whore," Em begs between moans, her eyes watering. "Fine," Lydia replies, helping her friend turn over on all fours, "like a fucking animal." She grips above Em's hip with one hand and rubs her taut belly with the other while she pulls her in and fucks her relentlessly. Em's wet pussy quickly forms a river of girlcum running down the underside of her belly and dripping onto the sheets. She starts slamming her ass backwards into Lydia, adding loud slaps to her constant moans.
Em's belly finally reaches the bed, and the pressure on top of her impossibly tight pussy launches Lydia into overdrive. She fucks her harder than ever, dumping more and more cum into her little whore, her shots making an audible *squelch* inside Em as they pound her womb. Em screams into the bedsheets until she's pulled away from them, lifted by her massive gut. "M-make me your fucking cumdump," she begs, clenching on Lydia's cock as she cums again and again. "Nngh... only if you're gonna take it all," she responds, griping Em's ass tightly and slamming into her harder.
Lydia grips Em under her arms and lifts her up vertically, holding her up with only her massive, tight yoga ball sized belly on the bed. "Such a little slut, full of all this cum," She lets out a few more massive, final loads, grunting with each, and her orgasm finally subsides. Pulling out and helping Em roll back onto the bed, Lydia digs a dildo out of the nightstand to seal the cum inside, and towels off to join her. They both rub Em's huge, gurgling, cum dump of a tummy. Lydia makes sure to massage it well, and Em moans with each rub and prod, especially enjoying the sensations around her pert belly button.
She can't help but play with her tits and become absorbed in the overwhelming pleasure and warmth as her yoga ball gut weighs her down. Lydia can feel herself getting hard again, wanting to make her partner even bigger...
