My aunty apparently knew that I was in her closet watching her squirt, and she came 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 aunty 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 aunty uses plenty of lube and spits 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.
