Right in the pussy!

They looked at her, "Hey so uh... if we do it we won't get pregnant right?" Asked Eliza.

Pebbelz shrugged, "If you don't wanna no you won't," she admitted.

Amelia turned to her daughters, "What? You really want to lose your virginity like this?" she asked.

Jessica looked at her mom, "Thing is mom I've already lost it. My boyfriend and I we did it like a couple months ago. Not that he's bad or anything but..." she looked at Pebbelz's huge prick, "I want to get fucked by a real cock." she said and pulled her clothes while her mother looked outraged at the revelation.

Eliza blushed, "Well I'm not dating anybody but I've always wanted to have sex... though honestly I was planning on having it be someone I actually loved but if I'm not gonna get pregnant I don't mind doing it." she said also pulling off her clothes.

Pebbelz smiled, "Well how about you and me start dating?" she asked reaching for Eliza and putting a hand under her chin, "I promise I'll be a good lover, though you'd have to share if that's ok with you?" she asked.

Eliza blushed even redder, "I'll... think about it." she said shyly.

Pebbelz just nodded, "Alright but so you two know I'm gonna fill you two like a balloon!" she said, that made them both stop as Pebbelz grabbed Jessica and held her up, her powerful hidden muscles allowing to hold her up like a doll.

Jessica squirmed, "Whoa hold on you aren't gonna make your dick smaller!?" she asked in panic.

Pebbelz giggled, "No it'll fit juuuust fine." she said.

Jessica looked at her, "No it won't! That's gonna split me in half!" she said panic rising.

Pebbelz raised an eyebrow, "How about a bet, if my dick fits in you, you dump your boyfriend and make me your main squeeze from now on. If it doesn't well I'll compensate your family forever I got deep pockets." she said. Little did they know it was a bet they would never win.

Amelia however was more than willing to take it mostly out of anger at learning her daughter had sex without her knowledge. "Deal!" she said.

Jessica looked at her mother, "Mom you can't be-Oooph!" she couldn't finish as Pebbelz brought her down onto her mighty cock. Jessica felt her labia widening as the cock went in, it spread her pussy wide but she felt no pain only the pleasure of being filled. Eliza and Amelia watched wide-eyed as the dick bulged out from Jessica's stomach a huge pillar pushing her skin up... and yet she wasn't screaming in pain, or her skin was ripping apart. It was as if her body suddenly became rubber she looked at the huge dick that was poking her skin out! "What the-? How are you doing this?" She asked.

Pebbelz smirked, "That's my secret honey now let's get to the pounding! I may not knock you up but I am gonna pump you full all the same!" she said and tightening her grip she began to raise and lower Jessica smoothly moving her hips back and forth thrusting in time with the raising and lowering. Eliza and Amelia watched Jessica be handled like a giant living fleshlight seeing the huge dick bulging out of the skin only to retract and bulge out again awakened something in them... a desire to be stretched and filled like that if not even more! Pebbelz did this for several minutes when the gurgling sounded signaling she was going to cum. "Here it comes! I'd step aside you two cause this is gonna be a big one!" she warned.

Both did so stepping aside as Pebbelz slammed Jessica down and orgasmed, the first shot of jizz was ejaculated with such **** that it stretched skin so much that it almost touched the ceiling! The second shot was less strong as the cum from the first shot absorbed it. Then the third, fourth, fifth, sixth and finally seventh shot, each one bloating her bigger and bigger, the fifth shot completely covering the side of the apartment she was facing and the sixth and seventh began to press against the window cum began to leak out from what little openings between pussy and cock. Pebbelz smiled as she looked at Jessica her face was pulled into a gaping open mouthed look her eyes rolled back and her tongue hanging out. She twitched unconsciously her body rigid from mental overload. Pebbelz still had her hands on Jessica's body and she began to change it. Her cum inflated belly began to shrink rapidly, as she made Jessica's body absorb the cum enough that she looked like she was 9 months pregnant with triplets. As that happened Jessica's butt began to expand rapidly, as did her breasts but much slower. When it was all over Jessica's butt was ginormous so much butt flesh that it seemed impossible to believe. A stark contrast to her bust for sure.

Pebbelz pulled her cock out of the canyon of a butt and went to Jessica's room and setting her on her bed. She then went to the mother and daughter who could only gape at her. "Nice huh? Your turn!" she said.

Eliza though held up her hand slightly as if she was a student in class, "Um can you give me some big tits? Like HUUUUUGE ones?" she said.

Amelia looked at her daughter, "Want to be bigger than mommy huh?" she asked.

Eliza looked at her chest, "No just... if I could I wanted to get implants in particular the PP string implants." she said.

Pebbelz heard of those implants that could allow for, theoretically, infinite growth. She had to admit the idea was arousing she had to do it. "Ok now then for this I wanna do it doggystyle lean on the couch." she said Eliza smiled and did as told leaning forward and placing her hands on the cushion. Pebbelz walked up her dick already lined up with Eliza's pussy, she then shrank her dick so that she could grab the ass and guide her dick in. Once the head was close enough she rammed it in, "God you're tight." Pebbelz hissed as her dick penetrated the girl. She felt something briefly stop her, and the loud shriek of pain told her she had broken the girls virginity. "Ah that's right you're a virgin aren't you a good little girl?" Pebbelz teased. Eliza was gripping the bed sheet so hard that her knuckles were white.

While Pebbelz waited for her to recover Amelia walked up, "At least one of my daughter's has a head on her shoulders." she said.

Pebbelz shook her head, "No she just has a different personality than you and that's not a bad thing, it'd be boring if our kids were completely like us every single generation there's no diversity." she said, Amelia didn't have anything to say to that.

After a few seconds Eliza said, "Ok I think I'm good." Pebbelz began to move slowly letting Eliza get used to it. After a few thrusts she upped the pace a bit her balls swinging back and forth like pendulums. Amelia couldn't help but crouch to watch those giant baby makers swing. It was... strangely alluring, she then felt it a lurch in her womb... as if it was wanting to be filled with the sperm that would soon be filling Eliza. After a few more seconds Pebbelz began to up her thrusting now thrusting hard and fast enough that her body slapped against Eliza's slight butt. Eliza was panting and moaning with pleasure, she could see why Jessica had sex it felt good, beyond good! It felt amazing and exhilarating she wanted it always... but she also wondered what it would be like to be on the other end, to be the one fucking instead of being fucked. Within a few minutes she felt the dick enlarge and knew it was coming. "Here you go honey your first creampie!" Pebbelz crowed and slammed it in hard.

Similar to Jessica her stomach bulged out immensely as he first shot filled her womb and shot with such **** her belly lurched up. Then the second and third shot filled it up bigger and bigger, as did the fourth, fifth and finally sixth shot. When it was all over Eliza was bloated much bigger than Jessica had been. But that would soon vanish as Pebbelz used her powers to convert all the sperm into growth... but as she did she looked at Amelia who was still staring at her huge balls. She then looked at Eliza and an idea sprouted in her mind. It was clear that Eliza was somewhat jealous of her mother and sister... and what better way to satisfy that jealousy than turn her into a futanari herself and let her fuck her mother and sister all she wanted? But Pebbelz wouldn't deny she wanted to fuck and impregnate Amelia herself but perhaps Jessica was more deserving of that?
