On 31 SF March me and my gf had dry humping I was naked and she was in her panty and shorts I was rubbing my naked penis on her covers vagina covers by panty and shorts might be there was precum on her shorts but before ejuculate I sepreate myself from here. I am sure my naked penis never touch her naked vagina..and she never uncovered her vagina..it was alwys covered by two layers of clothes..is it possible to get pregnant..and her last period was 21 march
