Guiding was probably a good idea. Anthony wasn't really sure he wouldn't have been able to do much of anything without the help. His vision was still a bit wonky and really, he probably would have made several jabs and attempts before finally deciding to give up and tell Justin to do it on his own anyway.
The feel of himself slipping into Justin threw his head back into the pillows under him and a moan to escape his lips. God, this could drive a bloke crazy.
