Naive Stepmom gives a Dick Rating

I come in to see my lovely stepson and he surprises me by asking if i will rate his dick for him. i think he must be feeling insecure, so i agree. it's my job as stepmom to build his confidence after all. so i take his penis out and begin to examine it, telling him how wonderful it is, much bigger than all the other penises i've seen. of course he begins to get a little aroused. he would like to see what i think of his dick when it's hard. i help him out, tugging away, starting to fell aroused myself. of course for any dick rating to be complete i need to see it cum, and so i take out my tits and encourage him to cum to climax...
