Lance groaned in pleasure as his cock was sucked, then gasped as he felt something else, a shifting inside of him, movement. "O-oh god!" Lance clenched his fists tightly, closing his eyes as he felt a wave of new pleasure wash over him, no pain whatsoever. The boy raised his hips, pushing his cock up further into Devon's mouth as the egg began to emerge, along with what was left of the beasts cum. "A-ah! F-fuck! So.....good!!" Slowly but surely the egg was emerging from Lance's ass. After a full minute, with one final buck of Lance's hips the egg slipped out completely, the sensation causing him to once again cum directly into Devon's mouth, though being his third orgasm in an hour there wasn't a great deal of cum from the still typical human boy.
Once it was over, Lance collapsed back to the floor, panting heavily, glancing down to try and see between his legs where the egg and a small puddle of beast cum were. The egg itself was quite noticeably larger than was normal for the species of beast that had deposited it. And larger eggs meant stronger, healthier offspring, which of course were much more valuable when it came to selling.
It seemed that not only had Lance's body carried and developed the egg in barely a quarter of the usual time, it had also produced what might have been the healthiest specimen of the species that had been seen in years.
