Last summer we visited family in guam.We stayed at my sister-in-laws home.One of the days we were going to go out while Christy ,my s-i-l went to work,with her husband,my wife Rose & our 3 kids.Rose felt sick in the morning and wanted to stay home.We went to prospect park for a few hours and were going to go out on my brother-in-laws pedal boat with the kids.When we got back to his house we went around the back to the small dock/deck.He said he wanted to bring some sunscreen & a towel or two,and he asked me to run up & get them.I figured I’d go check on Rose,see if she was feeling alright.The sliding glass door was locked so I went around the front and went in.When I entered their home I heard the loudest moaning I had ever heard in my life from upstairs.I went up the stairs and it got even louder.I quietly went up & peered into the guest room.John,their 21 yo son,was standing up with his hands holding a womans legs.Each hand was on the back side of her knee area and he had her legs spread very wide.John-John was facing me,looking down,and she had a few pillows under her head.She shouted out “Oh God,that feels so good John-John!!!” and I realized that it was my 43 yo wife Rose.John was banging on her p**** so hard and Rose had her hands on his abs caressing them softly.She starting moaning loudly,as he thrust,and I could’nt help but notice that John was quite massively endowed.his c*** must have been about 10″ long & thick.About twice the size of mine.Rose started shaking her head side to side,moaning “oh my God!” about 10 times.Suddenly John chuckled and I realized that he’d noticed me there.”Does it feel good Auntie Rose?Do you like it?Do you want more?” as he began slowly working it.”Oh yes!Yes!” Rose groaned very loudly,squeezing his arms.”I want you to f*** me like this all day John-John” she moaned to him and he gave me a s***-eating grin.he was torturing me.”I don’t like to be away from you now!” my wife confessed to him ,and I just stood there in shock.John practices mma.I know he could probably kick my a** pretty bad.”I like when you s*** it”he said,casually to her,and Rose replied “just come in me and I will again John-John,please!” I knew his dad always bragged about the girls that chased after her but I had no idea my bold but dreary filippina wife would f*** her sisters son!I have to admit,I was aroused watching him f*** Rose.It was the most vocal and aroused I’ve ever seen her during s**.
