Taylor missjudges Gavin, by A LOT

Taylor was relieved to see Zack vision of the scene was obstructed, feeling how Gavin's cock in her hand twitches, as the boy begun to violently shake his hips in unison to her hand movements, she was expecting to see him unload all over Heather's face and moment now.

But she waited...

... and waited...

... and waited... but besides serious amounts of pre-cum nothing have shoot out from his thick veiny dick.

She looked concerned at the boy she used to know since he was a kid playing with her brother, seeing growing frustration showing on his face, as his hips were moving more and more wildly, stokes of her hand no longer providing enough stimulation to him it seemed like.

Taylor gasped when she saw one of the more powerful swings making his dick push into Heather's huge breasts, Heather herself speechless about it, feeling **** hotness in the spot where his dick touched her chest, she looked bewildered both at Gavin, and then at Zack.

She only just now realized her boyfriends new position, with his head buried deep in between Hannah's enormous tits, and to her own surprised, she didn't feel any jealousy because of that, instead she found herself relieved that Zack couldn't see what Gavin just did to her.

But it wasn't the end of it. Feeling a marshmallow like softness envelop the tip of his dick for a second drove the shy and reserved teen boy's excitement beyond his limit.

Since Taylor no longer could make out with Hannah, she could turn her whole attention to Gavin for the moment, and she could not believe what she saw and felt.

Pushed beyond his limit Gavin roared, feeling more aroused than ever before in his life. Taylor was shocked seeing how the boys violently throbbing cock that she thought was rock hard before, begun expanding in her palm growing bigger and thicker, huge strained veins popping up down entire of its length, as if an extra liter of blood was suddenly pumped into it and Taylor could almost feel how his engorged cock begun pulsating in her hands, with every beat of his heart expanding and contracting slightly like a living creature.

It almost looked supernatural, but Taylor was a gynecologist's daughter, herself studying in medical degree. She immediately understood what transpired in front of her eyes, even though the results were much more spectacular than any of her studies prepared her for, but it all made sense. Gavin was a virgin, and his cock until just now had a case of partial phimosis, where his skin was too tight to allow his dick head to uncover completely. With how gigantic he turned out to be, boy must have always suffered, his cock never being able to achieve full erection, the pain of his too small foreskin chafing preventing him from reaching full size. Because of the incredible circumstances, the orgy happening in the room, he was able to push beyond his limit, and his foreskin gave way to the pressure of extra blood surging into his monstrous penis, for the first time allowing his genitals to take their full form.

And it was absolutely MASSIVE.

Taylor was speechless about it, but Heather ... ? Heather was totally mesmerized. She was looking with wide open eyes at monstrous veiny cock still moving back and forth frantically in front of her, the shadow it cast covering her entire face. Zack penis was huge, and one of the biggest she ever seen, but Gavin's engorged meatbat dwarfed him in comparison, his length easily as long as Heather's forearm, but almost as thick as her calf.

Taylor hand could no longer hold him steady, Gavin thrashing about his brain struggling to understand the new found sensation, the wide helmet of his cock head first time exposed to the outside world, driving the boy insane. The older girl tried to hold him back, but her small hand wasn't even able to hold onto his girth properly, and when her hand slipped, his hips suddenly lunged forwards startling Taylor, but almost killing Heather ...

... with a heart attack.

Although it would not be too hard to imagine the huge slab of meat knocking her **** if it hit her in the face.

Luckily for Heather however, Gavin's legs buckled slightly, when he launched forwards and instead of piecing her skull through her eyeball or something, his enormous appendage buried itself in between her equally impressive bust, the soft padding preventing both of them from suffering any injury. Heather thanked the god for the gift she received at birth, as it might as well have saved her life this day.

But it was too soon to think it was all over. Heather looked up into Gavin's face - but the Gavin she knew wasn't there at all, replaced by a savage beast with only one intend on his mind ...
