I love to oil up my gf and rub her all over while admiring her shiny sexy body. And then when I rub my oiled up body against hers and fuck her, wow, so primal, it feels amazing!
I should have mentioned that as well. I do the same to my wife and damn does it look and feel incredible. Makes even Missionary way more fun! I'll usually start with a full body massage (including oil of course). Due to my raging foot fetish there's usually a little foreplay with her feet. If I can manage not to blow a load on her sexy shiny slippery feet we move on to intercourse.
Because I like the look and feel of pre-cum so much I love sitting on our screened porch oiling up and stroking away.
