When i was a wee little crusty teenager i was in detention and my phone got taken away but thankfully i had an old samsung which had like android 2 originally installed with some goofy ass rom that ported 7 onto it which was im pretty sure the newest at that point and i used it to wank. It had like a 2 inch screen but all i needed is something suggesting that there was something slightly suggestive on the screen. If i hadnt done this i would have probably burst with cum or something cause i was one crusty ass teenager.
