Jen found herself returning the kiss partially against her will. The thought of two girls making out on a bus was really turning her on even though she had been straight less than an hour ago. Megan continued rubbing her thigh as their tongues entwined and Jen could feel something tugging on her panties. She didn't think too much about it as she kept kissing. A random thought about if she had a condom in her purse startled her though. If she was kissing a girl why would she need a condom? Another tug on her panties and she came up for air long enough to see that her skirt had bulged outward well above where Megan's hand was fondling her. The realization that she was getting a woody like she had joked about earlier made her blood run cold. She would have gone flaccid if Megan hadn't noticed her predicament. Fingers gently stroking up her shaft made her rock hard again and she nearly yelped in surprise. "It looks like Little John has come out to play." Megan giggled, giving Jen another stroke.
