Jerking off for Stepmom

My new stepmom, Lila Lovely, has a HUGE rack!  It drives me wild, and I have been jerking off all over our house and leaving my cum everywhere!  Every time she comes around, dressed in her short skirts and revealing tops, I get hard.  My stepmom is cleaning up my load off the living room coffee table when I come in, and she decides to have a little chat with me.  She tells me it will be best if she helps me jerk off since she's been watching me cumming all over and I don't seem to know what I'm doing.  So, my stepmom sits down with me and tells me to take out my cock.  She has me start stroking slowly, and takes her massive tits out of her tight tube top so I can watch her rub them as I rub one out.  My stepmom even licks her pretty nipples for me as I stroke, getting closer and closer to cumming.  Stepmom counts me down from ten when she is ready for me to cum, watching my load spurt into my hand on one, and tells me to go clean up so I don't leave any mess.
