My husband looooves watching me do this!! We have a small group of 'friends' who we can call on if we feel the need. Sometimes hubby watches and video tapes, other times he joins in. The most ive done is 6 at once but ive done it quite a few times. The attention is great and the feeling of different cocks inside me is a real turn on. If you havent done it, try it!
One time my hubby tied me up and blindfolded me (consentual) and had some people over. I was the 'entertainment' and the guys were encouraged to 'help themselves'. The highlight was when my hubby and another guy were holding my legs open while 4 other guys took turns at me and came inside me one after the other. We still watch the video for a turn on sometimes.
