My girlfriend and I attended a party that her son-in-law and her daughter was hosting. Her mother-in -law, Rose, was helping out. Rose is about the same age as my girlfriend but has a shapeless looking body. She and I would chat somewhat when were together at someones house. She always hugged and kiss me when my girlfriend and I left the social gathering. I started to get sexually interested in Rose after being together with my girlfriend and wanted a change in my sex life.
Rose and I decided to take a walk in the federal park across my girlfriend's place. Before I knew it we held hands as we walked. Rose squeezed my hand hard and pulled me into her kissing me hard and feeling my crotch. Her nipples was erect and I couldn't resist not touching them. We was near the rest area and went into the ladies side. There she exposed her small saggy breasts letting me suck on her nipples while she pulled out my cock and jerked my cock. We went inside the toilet stall and closed the door. I sat on the toilet when she started going up and down on my shaft with her mouth. She pulled down her bottoms exposing her hairy big long and used butterfly pussy and we switched places on the toilet. She spread her legs and held her loose pussy lips open and said, "Eat me! " I ran my tongue up and down and in that huge cunt. I was so turned on that I had to shove my rigid shaft in her cunt. While I was pumping her she played with her clit as I slapped her nipples.
That's when she confessed to me she wanted me to do a threesome with her and her son. She can't never have enough get enough sex.
