When Joel and Julia Roca started fooling around by the outdoor pool at their Costa Rican resort, they had a sneaking suspicion Julia's step-mother was spying on them. Bianca Resa watched it all go down from her spot on the balcony, from Julia's dip in the pool, to the moment Joel pulled her panties aside to lick her clit. As she watched the young lovers fooling around, all Bianca could see was Julia's inexperience at fucking, and how she could teach her a thing or two about pleasing a man. Bianca Resa gave Julia the push she needed to learn, sucking Joel's cock in a double blowjob, and then grabbed Julia's hips and backed her up on Joel's every deep thrust. Watch this erotic Milf threesome that made this an afternoon they'd never forget!
