Just wondering if this shit my ex-g/f and I used to do would be what some may consider "freaky." She love for me to bite her when we were fucking, sometimes I'd bite her pretty fucking hard when she was cumming and she loved it. She loved to be bit. Also I'd finger her ass sometimes when I was ramming her missionary, and sometimes I'd pull her hair and smack her ass when fucking her from behind. Also, she loved to play with my balls during doggy. This stuff freaky or do most couples do this?
