First time poster, long time lurker. Apologies in advance for typos as I'm typing on my phone at work. Apologies if this is long.
Anyway, a little background. I've been with my gf for almost 4 years now and we have a great sex life. She's about 5'2" with a gymnast build, has amazing D cups and an ass you could stare at for days. I'm a 5'9" with a muscular build, 6.5 inches cut with good girth. We have done anal a few times before and she loves to be fingered while I go down on her but this is the kinkiest anal experience we've had to date.
