Ok so I have been with my gf for about 4 years now and we do anal very occasionally but she only really does it because I enjoy it. I made her be a fuck slut for me the other day and I used and abused her, I inserted some anal beads up her bum while I was licking her to orgasm, I asked if she wanted more beads pushing in and she said no, so I pushed an extra one into her, she seemed pissed but took it like a good girl. The I bent her over and slid my cock deep up her bum but came straight away. I can't seem to hold it in when I am doing anal and nearly always cum straight away, I think its mainly cos I get to excited when doing it.
Anyone any tips on A) how to last longer? and B) How to get her to enjoy anal?
