Návštěva mé nevlastní tety, část 2

My step-aunt apparently knew that I was in her closet watching her squirt, and she comes into the living room to give me a little talk.  She is actually really cool about it and tells me she'll help drain my balls so I'm not so horny all the time.  My step-aunt takes off her robe to show off her big MILF boobs in a sexy white bra, then crawls between my legs to start jerking me until I get hard for her.  My step-aunt uses plenty of lube and spit to get me right to the edge, then she ruins my orgasm and removes her hand so I shoot cum onto my stomach.  Again, she jerks me until I am almost cumming, and again she ruins my orgasm and I spurt cum but get no  real orgasm.  She repeats this a third time, then, when I am so on edge I can't stand it, she jerks me and keeps jerking as I cum, although she has already drained me dry.  This'll be a secret between us, she tells me, and she promises she won't tell my stepmom.
