It's enormous, it's sexy and it has the biggest tits the world has ever seen. Guess.

Aaron felt exhausted. Drained. Breathing heavily, he lay on James' belly like on a warm, comfortable mattress, his head resting just under the giantess' ribs where it was gently raised and lowered by her deep breaths. James laid his hands on Aaron's back, her warmth seeping into his skin as they covered a good part of Aaron's body, and the hyper-dicked young man could not keep his eyes open any longer, falling into a deep slumber. Exhausted as he was, it was unplagued by dreams.

When Aaron awoke who knew how much later, he found himself cradled like a baby, resting against a bosom the size of beanbag chairs, Aaron's cock and balls resting on an equally huge thigh. Blearily opening his eyes, he looked up and was greeted by the warm, almost motherly smile of the woman that had been James. There was no resemblance to her old face, a wild mane of auburn hair framing a face that could launch a thousand ships - then again, James probably could push them into the water herself now.

"Juh-James?" Aaron's mouth was incredibly dry, making it hard for him to form words.

"M-mh," the giantess shook her head gently, still smiling. "It's Jill now. Lily came up with it, and I really like it."

"Yeah, it's--ungh, my head!"

"Oh dear, are you alright?" Jill sounded genuinely concerned, her eyebrows rising with compassion.

"Y-yes, just... really thirsty and... oh god, this headache!"

"Oh, I have something to drink!" The giantess let go with one arm, leaned forwards and Aaron felt himself smothered by an avalanche of boobflesh, the soft orbs covering his whole body. It felt incredible, warmth enveloping him, but it also meant that he couldn't breathe. Aaron began to struggle, but his arms were still to weak to move the enormous breasts smothering him - in fact, he doubted he'd ever be strong enough to lift even one of them. But before Aaron could suffocate, Jill leaned backwards again, freeing him from his boob prison. She brought a glass bottle with a reddish liquid to his mouth, encouraging him to drink. A first sip revealed it to be juice of some kind, and Aaron began gulping it down greedily, emptying the bottle in no time.

"Where is Lily?" Aaron croaked after Jill had taken away the bottle. A low 'clink' let Aaron know she had set it down on the floor.

"Downstairs, she's cleaning up the mess you guys made. You were out a while," the giantess answered, pulling the comparatively small Aaron tighter into her bosom. It was so soft and warm... Aaron felt all his worries slip away, his eyes falling closed again. Jill began humming and rocking him gently, Aaron's thoroughly drained balls sliding over her voluminous thighs. He felt safe in Jill's arms, and her...

"Hey guys, I'm done down--" Lily threw open the door, her first sentence interrupted when she saw her sister hug Aaron to her chest. "What the fuck, Jill?! You wanted to watch him, not smother him with your tits! Let go of my boyfriend!"

Aaron's eyes had snapped open when Lily had waltzed into the room, his mouth automatically opening to stammer an excuse, but all words left Aaron when he heard Lily refer to him as 'boyfriend'. Jill's reaction was the opposite.

"Your boyfriend? Did you decide that all on your own?" She pulled Aaron even tighter into her bosom, his upper body resting between her massive tits. They wrapped around his body tightly as Jill pressed them together with her arms. "Besides, I'm a much better fit. Downstairs, I mean."

"WHAT?!" Lily took an angry step forwards, fists tightly clenched at her sides. Aaron only now realized that drops of his cum were clinging to her legs, slowly being absorbed by her skin. "I was first, and this is not just about fucking, you know?!"

"So that's how you do that? First come, first serve? And fucking is a rather big part, or so I hear. How are you planning on keeping him satisfied?" It seemed Jill was just as shrewd and perverted as Aaron remembered his old lab partner to be. At least now, said partner's attention was focused on Aaron, albeit in a rather lewd way. And it certainly didn't hurt that Jill was smoking hot.

"I know a thing or two. How about you, sister?" Lily fixed a cold stare on the giantess. "As far as I know, you'd still be a virgin if not for my stud here!"

"Don't think I don't notice that little 'my' there," Jill replied with an icy voice. "And what are you gonna do? Ride his dick until he spurts his jizz all over the wall? At least with me, Aaron can cum into a pussy that can take him!"

"Why is it always about sex with you? Is that all you can give him?!"

"No, I can also carry him and his magnificent cock no problem. Don't act as if you could do that with anything less than a wheelbarrow."

"Wooow, so you'd baby him. As if he'd want that."
