Jeff stared at amazement at his girlfriends big hard dick, making his seem even more pahetic and small.
He looked a Tricia and saw her smirking, also comparing their penises.
The idea of his girlfriend having a bigger manhood than him was too much to take, he felt his now tiny pecker shrivel up and retreat back into him.
'Aww poor Diddums' Tricia said, ' Is your ickle winkie afraid of the big bad cock?'
Tricia slapped her fat dick against Jeff's floppy little nubbin.
' Its more like a clit than a dick,' she said, ' maybe we should give you a big butt to go with that haha...'
'Oh God no,' said Jeff, 'Dont you think youve done enough damage?'
