I lowered the duvet and Norma turned to see my rock hard fully erect penis staring at her,Norma told me that in all her years she had only ever had one man and that was her husband,she had enjoyed their love making and that her husbands penis was nowhere near as big as mine.I assured Norma that i cared for her a great deal and that i'd never do anything that she was unhappy with ,then i took her small soft hand and placed it on my throbbing cock.I layed back and relaxed as i allowed her to come to terms with it by allowing her to wank it slowly up and down,i wanted to see her small delicate mouth stretched wide with it's girth but i contented myself for the moment with putting my hand under her nightie and caressing her lovely plump backside and her wet quim.Norma had sucked her husbands cock before and it was suprisingly easier than i thought to get her to put her hot mouth around mine."That's it Norma...suck my big hard penis" i said in a state of lust,i thought that my dirty talk might upset her,but it seemed to encourage her.
