my girlfriend is extremely attracted to female muscle. she even loves it when we compare my biceps to biceps of other girls like i.e. kati rubos or johanna dejager who have awesome peaks and some serious size. when we have sex she likes when i flex my biceps, but when she looks on a picture of johanna and sees the difference in size, she really gets turned on and the reason for her orgasm is, that the female muscle is so much bigger. awesome, isn´t it?
