As the Ty clones walked with the blob of Ty, the clones got so excited that they decided to.... have group sex on the street.
The clones divide into small groups, cuddling each other and they start to grind on each other's dicks. They moaned and gasped in unison while doing so.
As the clones start cumming, some of the cum landed on pedestrians, turning them into Ty's clones too. The small groups of Ty's clones form into separate blobs of Ty. With more Ty's clones, there's more group sex, more blobs of Ty.
While the original blob continues to walk, the original blob of Ty's start to grow slowly, almost as high as 25 metres.
