Ive broke in a few like that, no O girls. It takes some work but most of the time once they realize they are NOT going to wet the bed and actually let it happen they love it or course. A vibrator/back massage works wonders also.
Dont just whip out a 12 in black vibrating dildo with nubbies and the optional anu$ pleasure and expect her to say Ohhh aren't you sweet. hahahahaha

It's like with a true virgin it's best to have sex the first time with the light off so she cant see the monster coming at her to violate her. hehehehehe

OK now get on with the back massage, work your way down and give it some good attention. Learn so good oral skills, NO 2 minutes does NOT cut it, how would you like it if she gave up on you in 2 minutes. OK you might not last that long but......

personally I try to make sure my woman/women/girls/??? have a least a couple O before I do. I guess that's why even after my divorce my ex kept coming back for more. Dont tell her BF tough.
