I like doing it anywhere! The face is a big fantsy for me, I don't know why, but I would never do it unless someone asked me. I've been squirted in the eyes with alcohol hand rub accidentally, and that stung for ages, so I can see why no-one likes the face very much.
My wife was giving me a handjob one time, and she was up the top of the bed kissing me. Unfortunately, my load didn't go where she was aiming; she had me shooting a massive load which went over hr stomach, breasts and on her face before hitting the headboard! It took her a while before she believed I didn't do it on purpose :( |
