Ultimate shoulder rides

My son and my mom.
Since i was a boy,i liked lifting up and carried bigger girls(women),and was lucky enough to have mom who enjoyed been lifted or carried,she said that makes her feel light,young and beautiful.Now i have a wife and 12.y.o.son,who likes to prove his strength this way too,but my wife,unfortunately not likes it so much,she just lets him to lift and carry her sometime only for his pleasure.So,this summer,when we're visited my mom we're spend a lot of time at  the pool in our backyard,once Martin looks at his mom and asks me ''dad,how do you think, can i get my mom on my shoulders?'',i said ''i think yes,but i have better idea",-''what?" -''let's play a trick on granny,can you secretly swim to her and lift her on your shoulders?".I was just curious about her reaction.''Are you shure she wouldn't grumble at me?''-he asks,-''do you remember when she grumbled on you anytime"-i repleyed.So he swam to her,dived and gets her on his shoulders, at first she was a scared a bit as she don't expect it,but when she realized what's up she giggled,kissed him on forehead,and he carried her for about 10 minutes.Just some words about my mom,she was very young when she gives birth to me,and i was same age when i had a  son,so she's just 48 and looks like five years older Selma Hayek,so he likes to carry her(we all know that boys likes beautiful girls,no matter who it is).Lately,when i asked Martin what it's feels like he said''you know i like to lift and carry mom,but i think she's not enjoy this,but Amber-she's so different,i think it's makes her really joyful and happy(they thinks it's cool to call each other only by name).So,since that day and till we're back home,everyday when we're were in the pool he carried her for some minutes
