My girlfriend doesn't want to try a*** but I think it's kinda hot. So when she's sleeping I'll rub her p**** until she's wet and then use that to lube up my finger and slide it right up her tight ass. I have only done 1 finger so far, but I'm going to gradually stretch her until I can fit my c*** in there. Either she'll try it willingly, or I'm going to slide it in when she's sleeping and have my way. It's ok though, because I'm not f****** related to her.
