My wife has really gotten into groups and I love seeing her on her hands & knees being spit-roasted, it's great watching her getting pounded from both ends and seeing those beautiful tits swaying around just begging for some attention which they most always get!
Another of my favorites is her laying on her back along the edge of the foot of a bed with one man pounding her pussy & another filling her mouth while leaving full access to her titties for the other men present to massage & suck on. She is not into any kind of ass play but loves having her pussy & mouth filled with cock while multiple hands & mouths are working over the rest of her body and I love watching her going wild while a group of men are working her over really good & giving her multiple orgasms!
Come to think of it, if she's having multiple orgasms while getting other men off I love whatever position she is in!
