Have not encounter this kind of case before but.. yesterday.. having half hour of fun with a 18 yrs old girl.. start up.. everything okie.. and she was okie with everything.. but near the end of the half hour.. she start to cry.. and.. my hand on her legs.. can feel that she is shaking.. omg.. and then the phone start to ring.. sign of time up.. lol.. and i have to tell her to take it easy.. maybe.. because.. i take too long to finish.. x her completely half an hour non stop.. in different position..
