It would be such a thrill to rub each others cocks in the panties as we chat about wives, partners, girlfriends etc. After sampling a lot of lovely stiff cock in panties I would like us all to pair up for some mutual masturbation and deep kissing as we all wank and gasp, pulling on the others penis. Then the sex would get serious, as men in turn asked for another to use their mouth or fuck their anus. It would be an awesome sight to see all these lovely cocks in panties being sucked off, or sodomising spread assholes, until the room was filled with the sound of mind-blowing orgasms as we all ejaculate in each others holes.
To end the event, it would be lovely to see men exchanging panties to sniff and lick, before kissing goodbye and promising to spunk in their donated panties as much as possible.
