to DesertDad54 :It is hard to understand the dynamics of the couple... it may be that the act was initiated by the older guy and the younger one was reluctant at first... if you haven't experienced an older guy getting into your bed and quickly mounting you...then the reluctance might seem odd... I had an older family friend who stayed with us now and then...from early on he liked to get into bed with me and cuddle and fondle me... it soon developed into much more serious love making where he took me as often as he could... sometimes when I was tired and not feeling in the mood... I have to confess that once he began to fuck me I would start to get excited and though submissive would enjoy his lovemaking....
to DesertDad54 :Everyone experiences sex differently depending on the partner and what emotions are experienced. I remember some encounters with much older guys in my youth where the way they made me feel at that moment was very feminine and I was hesitant to let that feminine side through. I did a couple times and I felt shy in expressing myself. I've always been a versatile Bisexual, but those moments where I was trying out total femininity were odd journeys.
