Nervous, surprisingly totally satisfied after a healthy orgasm, happy my husband was pleased, a little confused on what I was feeling about having another species in me, then more relaxed as hubby told me how fantastic I was and he gave me a relaxing massage and penetration whispering if I was wanting to enjoy the dog later... I did feel some guilt of having such a wonderful orgasm from our dog, but hubby kept up a steady pace and when he felt me getting close, dove down to lick me to an equally satisfying result.
The rest of the journey has been a learning process, aided by chat friends and another couple we share with.
