Hopefully you've read my post 22613. My mother in law tagged along on a cruise with my wife and I....separate cabins. After a day at sea my MIL pulls me aside and tells me she needs to get laid and she's got a plan for us to be alone just follow her lead at dinner that night. At dinner she explained how she had started walking in the morning and it was great etc...then she asked us to join her and we'd walk around the ship...she knew my wife liked to sleep in and I am an early riser...my wife says shes out and suggests I go with her mom and let her sleep in!!! It played out just like my MIL planned..lol. My "walk" was to my MIL cabin at 7 am. I fucked her for over an hour. We met each morning of the cruise for a good fuck. The big adventure was an evening the 3 of us were in the ships casino. We were all separated playing slots...My MIL tapped me on the shoulder and says....give me a 1 minute head start and meet me in the family bathroom across the isle...I nodded....I went in locked the door...I opened the stall door, she had her pants off bent over the toilet ass facing me and says "fuck me baby" I unloaded in her pretty quickly,she kinda sighed in disappointment. she turned and sat on the toilet and said "eat me" I was a little grossed out but a little turned on..I got on my knees and went for it eating her pussy full of my cum....turns out I enjoyed it and so did she cumming on my tongue. It was a great trip!!
