All prenegotiated, but being unexpectedly pinned down by some people while my fiancee directed, beaten until I'm a puddle of gay horny goo, and then having them use their new strap on me. Having my face shoved into the grass as they got rougher with me, cumming infront of strangers around my fiancee's strap, barely any clit stimulation... mmmmm memories. And the bruises afterward were to die for.
