Oopsie

Fortunately for Adrien, his urges were about to be solved, as the clumsy Marinette fell back again, accidentally pressing her half naked butt to his bulge.

Blindly trying to grab onto anything behind her, the girl's right hand accidentally slipped behind the elastic waistband of her crush's boxer briefs. The seamstress' delicate fingers stroked the boy's manhood, much to his unexpected pleasure, as he caught her by her bottom.

He gasped as he felt the throbbing sensation in his pants reach it's climax, leaving the palm of Marinette's hand warm and sticky. He tried his hardest not to make a sound, almost **** due to the immense pleasure he was feeling.

He felt guilty for groping the poor girl's juicy, round, panty-clad ass, because he was enjoying it's firmness through the soft, smooth, cotton material of her panties.

His fingers were so far down that she could feel them by the crotch of her undies, as they slide up her ass to move to a more appropriate position around her hips. The blissful feeling of his touch leaves her gasping in pleasure, as blood flows down to her lower abdomen. If his fingers were still down there, he would have felt the crotch of her panties dampen as the cotton absorbed her feminine juices.

As Marinette turned around to see his now blushing red face, which matched her own, she pulled her hand out of his pants. She was so ashamed of what just happened, that she hid her face into her hands, accidentally smearing Adrien's cum on her face.
