"Um... sure? I guess, but you want pet dog sized rats instead of like, actual dogs?" Eric asked in slight disbelief.
"Nope, just those two rats specifically" clarified Leah.
"Anyways, can you please let my finger go now?"
"Fine, go clean yourself up in the bathroom, and then meet me in my room in 5 minutes."
Eric goes to use bathroom and wash your hands as instructed before heading towards Leah's room. When he enters unto it, he is met with the sight of Leah waiting for him in her bed with her ass raised up and facing the doorway. "Well, don't just stand their staring. Come over here and start fucking this adorable asshole I have" demanded Leah, which Eric could only nod and comply with eagerly. He could see that she had already packed a good bit of lube around her hole, so he didn't waste a second and pushed into her until he felt his balls rub up and get lodged in between her two amazing ass cheeks. His cock was fully extended out of his sheath too, so Leah was getting the full 2 and a half feet of horse dick burried deep inside of her. Eric could feel every twitch and quiver her ass made, which only continued to suck him in, as if she could use her ass like her mouth.
What it really was is that his cock was so thick that it had created a perfect seal when it entered her ass and now was vaccuum pumping her ass. It was an interesting thing to witness as Leah would burp everytime he thrusted into her since it pushed the trapped air inside of her digestive system up and out of her mouth.
Now that Leah had a fullly grown and developed body, she was able to experience way more of the fun than she use to. Since she was taller as well, she wondered if she now could actually fit his cock inside of her. Either way, she wanted to try it. The other thing that she was liking, was her boobs. Having gone from flat to having a nice and large pair of breasts initially had annoyed her greatly due to the sudden weight she now had to carry around. But currently, those weights were feeling really good as their nipples rubbed against her bed sheets with each thrust of Eric's cock. Having them swing freely below her now was completely rewriting her opinion of them.
Several minutes later Leah felt the telltale sign of Eric reaching his limit and clenched down hard with her asshole, tightening it around his shaft which caused him to instantly start filling her ass with his hot and thick cum. Due to his balls growing in size as of late, the quantity of cum he released into her had gone way up as well. She could feel the pleasantly hot cum begin spreading out around her intestines as they slowly filled up. It was a unique sensation as she for the first time could track her intestines layout. Finally, to her surprise, her stomach began heating up and she felt his hot cum flow in and up her throat before finally trickling out her own mouth and onto her pillow. It was just a few drips, but it was more than enough to give her a taste of his cum, reigniting her desire to consume some of it. So she eagerly began swallowing it all, even attempting to collect the bit that had spilled out.
Eric on the other hand, was shocked as to just how long his orgasm lasted. He felt like a fire hose as he just kept releasing more and more cum inside of his girlfriend's ass. "Woah! That is so much more than usual. Are you ok Leah?" He asked, concerned for his girlfriend.
"Fuck Yes! That was amazing. I have never felt anything like that before. Damn I wish I had a cock to fuck you with now so that you could feel what I just did too!" Joked Leah. Although she was being completely serious about wishing she could share the feeling, she was happy with her current situation. "Hey, since I am bigger now, maybe you will fit it in my pussy better too?"
"Worth a shot" agreed Eric, who slipped on a condom, which he had bought in the largest size possible, and slowly worked his dick inside of her. And he fit a lot easier, and deeper too. Soon enough he was pushing up against her cervix when she herself slammed herself back onto his cock, forcing it into her womb. Where it finally got stuck. His gland was flared which prevented his cock from sliding back out of her without causing her a lot of harm.
"Oh fuck! Why did you do that! I think I am now stuck inside of you Leah!" Panicked Eric.
"It... feel... so... goooooood!" Panted Leah, as she was currently being vastly overwhelmed by the insane pleasure she was currently feeling. Every slight movement sent her to the brink of orgasm. Even just having Eric talk was causing his dick to twitch a bit, which was all he had to do. Both of them came at the same time, and watched as Leah's belly visibly begin to descend as she filled up her womb with a mixture of their cum. It didn't hurt her at all either. She looked 9 months pregnant when it was finally over, and Eric could safely slip his cock out of her. She kept the condom inside of her and tied off the end, trapping the semen inside her womb, while ensuring that she would not become pregnant. She even used your cock to help pack the condom balloon full of cum into her womb.
"Haha fuck. I have never felt so full in my entire life" said Leah as she laid down on her back, stretching herself over her bed as Eric took the open spot beside her. They both could see the mound that had become of Leah's stomach poking into the bottom of their views as they staired at the ceiling, which was entertaining to say the least.
"One day this may in fact be our real child inside me, you know" said Leah as she gently patted her belly mound. Eric pictured that scene and desired it immediately. But he had a horse cock... so would they even be able to get a baby through sex? Or worse, would she end up giving birth to a foal? That thought somehow didn't seem too bad either, which brought him a lot more concern for himself. He had to find the Chronivac and fix this, or he may infact become the father to a literal race horse.
