Yes - a quick release and gets off the bus

Emma was torn by competing needs, as she worked her hand underneath the skirt to grasp her naked cock. She knew this was wrong, to jerk off right next to this sexy girl, but the lust pounding through her body told her it couldn't wait until later for it's release. The fear of discovery sent adrenaline through her, forming a heady cocktail with arousal which drove her onwards.

She had jerked guys' cocks occasionally, so she had a starting point, but being in the receiving end she was quickly able to refine her technique. Trying to keep her arms as still as possible, she worked the impressive length, fingers dipping occasionally between her thighs for her wet slit so she could smear those hot juices over her new meat.

All the while, she stared at the tight little ass and long legs, just occasionally glancing up to sneak a peak at the gentle outer curve of the girl's tits. Her mind was filled with disturbing yet erotic images - of forcing the girl to her knees and stuffing the cock down her throat, of yanking those jeans down right in front of eveyone and filling the girl's pussy right there. In an effort to resist the temptation to actually do anything, Emma focussed instead in cumming, visualising her impending eruption.

This worked better than planned, as Emma suddenly realised her cock head was only inches away from the girl's shapely ass. Unless she wanted to soak her own skirt, she was going to have to blow her load across the svelte, jean wrapped curves. The idea of doing that to this wholesome looking young woman pushed Emma over the edge. She bit her lip to keep quiet as the most intense release she had ever experienced overwhelmed her. It was as if a tidal wave had been building inside her and was now gone, released from her in a fountain of hot, sticky white goo that arched through the air and splashed across the denim in front. As she subsided, Emma glanced up, relieved that her target seemed not to have noticed, and then down to the pearlescent streaks which covered both of the tight globes.

Guiltily, Emma adjusted herself and got off the bus. As she manoeuvred through the crush, she recieved a polite smile from the young woman who now unknowingly carried Emma's cum across her ass. Her cock twitched despite it's recent orgasm and Emma hurried to leave the cramped space. Making it off the bus, she glanced around.
