She looked at Marcelina, who was lying down across the three seats opposite, her head nearest the door and one leg down the side of the seats with her foot on the floor. The sun was shining in on her bare legs and up to her breasts. Ölga could see the nipples protruding from under Marcelina’s black silk top, and as she looked down at the very short yellow shorts, she could see the white panties beneath. Ölga was sitting up with her head against the window side of the compartment and her legs stretched out on the three seats before her. From this position could see in the open gap between Marcelina’s left thigh and the bottom of the yellow shorts. She could also make out the slight bulge in the panties. As the train jolted from side to side, Marcelina’s left leg swayed from side to side, and it was this movement and the warming effect of the sun on her legs and groin that made the blood start to flow and for the swelling to begin.
