I am f****** my gf's mom. I am 35 and my gf is 33. Her mom is 55. I flirted with her one day about 4 months ago and she went for it. We f*** probably 4 times a week. We even got in a quickie while the gf was making dinner. Mom was wearing a skirt and no panties. She pulled her skirt up and got in my lap. She had to bury her head in my chest to stifle her o******. I busted my nut just 30 seconds before she walked in with dinner. One time the three of us were in the hot tub together. The gf took off all her clothes and asked if we were going to as well. We all did. Mom said her shoulders hurt so I offered a massage. She got behind me and I slid my d*** in her p****. Her moaning was o****** but the gf thought she was just enjoying the massage.
