I chose oral with vaginal being #2. For me, there is nothing better than being pleasured orally. I can relax and let my wife work her tongue, lips, mouth, together with her hands on my cock. The feeling, the build-up, the tension of my rock hard cock in her mouth is thrilling for me. I love to leak precum in her mouth and then make her kiss me. She rarely lets me ejaculate into her mouth but when she does - OMG. I find that so intimate.
I also enjoy licking my wife's pussy and clit. I enjoy 69 sex with me on top or with us both laying on our sides. God, the look, feel, and fragrance of her pussy drives me wild.
