First threesome not expected by me after too much partying

My wife got a lil' too much partying in one night and my hottest friend stopped by for a beer, next thing i know she asks me to play with her tits with him sitting across from us. i sent him for a few more beers and this is what he came back to. i never thought she would ever do this, part two is about hr later after i break out cam corder.
