Her one piece suit came off easy and she was standing there naked. Her boobs sagged slightly, her dark untrimmed bush did not match her blonde hair. I...had not had sex in three months so my dick started to stand at attention making a tent in my swim trunks. I wanted to throw her in bed and get back to my room and twist one off before everyone came back from the casino. My girlfriends mom, her name is Mary, took note of the swelling in my trunks and asked if I liked what I saw? Yes Mary, you are. Yes"She let out a loud sultry laugh"Good, like kinky, little wimpy muscle freaks. Like to see them tremble. Loveseeing the cock pop every time I flex a muscle. Trying pulling my arm down"She saysI tried as hard as I can but can't seem to pull her arm down.I can't evenbudge it."This all part natural and part years of working out my body to perfection"She says"I s..shows miss lee" Flattery will get you everywhere" She saysShe slides my hand down her ass and has me squeeze. Her ass is nice and. Still she had to admit she looked good in the iconic outfit of nerd lust. She and her friends had saved for months to go to Dragon-con. Unable to afford a hotel room in any of the 6 hotels hosting the convention in the 2 square blocks of downtown Atlanta taken over by 50,000 nerds every year. They had to resort to getting a cheap motel room within walking distance of a Marta station, and a weekend subway pass. The major advantage being avoiding the several hundred dollar a night inflated cost. I can only imagine she was in there getting off, thinking about her son-in-laws cock. I had a huge case of blue balls and when she got out I woke up and headed to the bathroom. I jerk-off thinking about my mother-in-laws ass. I exploded all over the wall and had to clean up the mess.My father-in-law asked if I could take over and I drove for the next three hours before pulling over and we all slept in for the night.The next day we got into the same routine I drove for a while and then he took.
