A vibrating horn would add to the fun for sure. I don't know how you could consider that a bad thing.
For some reason, I read this as "air horn." That would really add to the fun! I'm kind of sadistic, though.
More like it would be fun for someone in the next room (or on the toher side of a wall) who wanted to screw up the mood.
I used to find it the height of amusement when a couple decide to leave you in a room and wander off hand in hand down the hall for some loud nookie, to start adding your own brand of flavour to their sex life by yelling out suggestions, doing commentary, and cheering.
I was pissed at the time and putout that they kinda left in the midst of conversation with me to have a root. The male (a mate of mine) came out to have a go at me and gotall aggressive. I laughed my arse off at him and then he walked up the hall and whispered "C'mon mate just give us a break hey....we'll keep it down"
I let his keep his pride and apologise to his girl later in an ashamed "Sam told me I had to say......" :lol: Brownie points to him and a favour in the favour bank for me.
