After a busy evening most of the crew were in the back galley taking care and securing the galley and counting the bar money. In the front galley me and the senior FA were left on our own to secure the front galley. The senior was blonde and very fit, she had her breasts as I always liked them full and beautiful. We closed the curtain so not to let the pax be disturbed with us cleaning. Without noticing I got hard and this was noticed by the senior and with out warning she teased me grabbing a good hold of my cock. As if nothing happened we continued our work. As a revenge while she was cleaning the ovens I lifted her skirt from behind and then she looked at me and said these exact words ” so are you going to continue or what”? In seconds, we were in a different position. She was holding on the bussel (where the slide is stored) and I was ramming her from behind. It didn’t take long because I always fancied her and quickly came. Thank God for that because seconds afterwards, the bar person came up to give us the Cabin secure signal.
