Probably the last one. My girlfriend, who I just kissed, Loves it when I use my fist. I put it in up to my wrist, Then give it just a little twist. Late last night we had a trist, She yelled at me "Shove in your fist. Do it now I must insist." I tried my hardest to resist, Which seemed to make her rather pissed. "I insist you use your fist," she hissed. "It is a feeling not to be missed." Why does she like it when I fist her? Don't know. Go ask her. She's your sister.
