Grandma's Friend An Enjoyable Older Woman Slut My First Experience

My grandma and her lady friend Sue hang around a lot together. Sue turns out not to be a lady but an aged slut. Grandma invited me to tag along to tag along with them and see the fall foliage. It was getting dark and we was some distance from home. We ate dinner at a place next to a motel where we got a room for the night. While we was eating I couldn't help notice Sue's cleavage. Sue's cleavage end up giving me me a boner.
In the motel room while grandma was showering Sue played around with her bra trying to get it to hold the tits she has. Her tits wanted to fall out causing me to get a bulge in my pants which I couldn't hide from Sue. I noticed Sue smiling and she opened a bit more on the top while looking in the mirror.
Grandma took a two bed room. One for me and the other for grandma and Sue. I didn't bring any sleepwear. I had to sleep in my boxer. I watched the TV very late and shut it off. I must of fallen asleep and started dreaming getting hard thinking of Sue. I didn't know my shaft poked out of my boxer until I felt a mouth on it. At first I thought I was just dreaming but when I opened my eyes I was pressing and holding Sue's head on my shaft . She smiled and edged herself on me jiggling shaking her tits with her hands over my shaft. Then she lowered herself on my shaft playing with her clit. " Oh , you feel so good in me ! This old gal can give you the greatest head you ever had, " While she was busy giving me head I groped her hot aging tits, which felt fantastic that I exploded hard in her mouth causing her to show my load that I gave her.
" You need to stop by my place and pleasure me , letting my granddaughter see the size of your dick ! " Sue whispered to me not wanting grandma to hear her being an aged slut.
