Human fartbox centipede

Multiple boys line up in a line with their buttocks exposed and spread the cheeks. Each boy tongue punches the boys in-fronts butthole and rims gently whilst reaching round and cupping the balls to work the shaft . This then symbolises the look of a centipede. (Usually results in cumquake of 7.8 on Richter scale).

For example Cameron, scott and Rhys make the perfect human fartbox centipede.
