I've never had a gf whose mom did this, and I seriously doubt that any of us have, but it's a great fantasy if both mom and daughter are hot. I've dated some girls whose moms were pretty hot, some looking like an older sister instead of mom. I've messed around with a few moms like that, but not with the daughter present. I've fucked a lot of girls, but the moms never helped. But one of my gf's aunts helped me fuck her neice because she wanted to be fucked too.
