funny you ask that...
my EX EX girlfriend of 3 years one day said to me "i was watching this sex show on TV and someone called in and said that it feels good for a guy to get a finger up his ass while you give him a blowjob...can I try it on you?"...
Needless to say I was shocked...this was coming from the girl that wouldn't let me stick it in her butt...so I used it as a bargaining chip...I said if I could anal fuck her she could do it.
She did it for a few seconds...then I was FINALLY able to fuck her in the ass by making her feel guilty...However, I only was able to bang her in the butt butt 2 times...no more after that
Ohhhhh well...
