Michael had watched Keiko's resistance crumble from his bound position, the girl had been brave in her persuit of resisting, far braver than him or David who had given in too easily to their male urges. However it made little difference if she had fought or not, as she was now back where she had started, on the floor between his leg, his penis standing up before her.<br/><br/>The twine around his manhood had started to feel tight and a little painful long before they had arrived here in this room, let alone after Keiko had been sat before him, the attractice girl causing another rush of blood to his already engorged penis. Ms Bell however raised the pressure in his groin another level when she leaned in close to Michael, her hand touching around him made him try to stiffen further, and combined with the twine made his penis feel like it was ready to burst, and the less said about the pain in his balls the better.<br/><br/>As his teacher explained what would happen next Michael knew it was going to be a mix of heaven and hell, he would get his penis sucked by the lovely Keiko, a dream in itself, yet on the other hand he had to try and hold back his orgasm. A part of him just wanted to give in and cum now in the hope of getting this twine off of his penis, but at the same time, would he even be able to cum with the twine wrapped around his cock and balls like this? He'd soon find out.<br/><br/>Michel's eyes met Keiko's as she moved in closer to his penis, it was an awkward meeting of eyes, Michael nodded his head, almost trying to comfort her and say 'we're in this together', and he hoped it didn't look like he was just urging her on to suck his cock. Despite this a muffled groan escaped him as he felt her lips slide over the tip of his cock.
