Rubby Belle couldn’t have guessed the first day moving into her new place with her boyfriend would end in a naughty threesome with step-mother joining in. Shalina showed up to encourage the young couple, but went off to have a moment alone with an erotic book she found sitting one on of the boxes. Just her luck that Matt turned the corner and found his mother-in-law masturbating in a bathroom. Shalina seized the moment to put her mouth on Matt’s cock, and when Rubby caught them in the act, she showed the young lady how to suck a cock like she does. Matt got to enjoy two lovers at once, as Shaline put Rubby through her paces and taught her all kinds of new tricks in bed, from how to grip the shaft, to how to best ride the cock to a powerful orgasm.
