Without so much as finishing her sentence, Emma's hand shot to Jen's dick, which slumped limply over her feminine hip. She reached down and pressed it between her tits, and almost had it back in her mouth before a much more interesting idea entertained her.
"You're on the pill, right?" A nod of desperation from Jen was all she needed. She licked her lips, seeing Jen's hair spread on the floor, her cum-covered hands curled away from her body in pure bliss. "Good, because this is not the time to get pregnant. Besides, I don't think condoms really would work for us, anyway."
Emma flipped Jen's still-hardening dick around 180 degrees and shoved it without warning into Jen's pussy. At first, it was too much - the combination of feeling stretched more than ever before (she had the biggest dick she had ever seen) and squeezed more than ever before (everyone at school agreed that she was the tightest girl by far) actually shot her dick back out, spraying Emma's front like a garden hose. Emma jumped and laughed. "Holy fuck, Jen, you're such a pussy! At least you like your own!" She shoved it back in before Jen's cum subsided.
After stretching Jen out for a while, she felt that she was missing out. She gave Jen a break (which Jen used to drain her balls) and stood up, her now-pendulous cock swinging at her knees. She propped Jen up against the ottoman, ass-up with pillows against her back. Kneeling down, her cock in Jen's receptive mouth, she got back to work. Fucking, while it had its rewards, was hard work. If she wanted to see Jen really cum, the was by far the best way to do it, and she still got a bit of pleasure herself in the process.
Streams of jizz and cream were now free to run down Jen's body and over her mounds. The warmth of the liquid felt insanely good on her tits, and she felt them swell a little farther. She would have to buy DD bras, or at least some good nipple tape - they seemed to defy gravity in their firmness. Her hands milked Emma's cock, which rewarded her every now and then with a cumshot big enough for a pro porn star. It goes without saying that these volumes were nothing compared to the loads of tonight.
For all her talk, Emma proved to be little better than Jen at fending off her massive orgasm. "Fuuck," she yelled, dipping her head back so that her long hair grazed her ass cheeks. After a few spurts, Jen pulled the dick out of her mouth and somehow managed to herk the rest of the load right onto her tits, completely covering them with stream after stream of thick cum. It was a difficult task for her, because her hands were completely numb from the sensation of her own thick monster cock filling her pussy. "Don't you even think about cumming, Jen!" She said, and pushed as much of Jen's penis into her as she could, pushing the huge balls to both sides. "I'm longer than you now."
It was true. Emma's dick had stretched out to about 20 inches, and its shaft snaked over Jen's face to where the head lay leaking just past her armpit. Glancing up from below, Jen saw the underside of Emma's balls dripping with her own pussy juices. That was enough for her.
She came so hard that she could feel it against her walls, blast after blast flooding her insides. Emma, oblivious at first, felt the tube in her hands squeezing out its cum and played at being upset. "Stop it, Jen! I told you not to cum!"
Jen felt a desire to please Emma, and after failing enitrely to control her orgasm, and spraying herself out of her pussy again, her quivering dick drooped down between her full breasts, throbbing and in need of release. Her balls were slowly growing bigger.
"Oh wow, you really need to. Well, fine, but I expect better next time. Are you gonna jerk it? Shoot more on me? Stuff it back in?"
Jen couldn't hold on any longer after hearing Emma's approval. Cum shot over her nipples, blasting off of her chin and over her shoulder as her cock fired mercilessly. Emma simply watched, her own cock in her hands, rubbing herself slowly, as Jen passed out again.
