Seduced at school

I was 17 when a girl from school touched me in the showers. At first a thought she had bumped into me by accident, but then she pressed me against the wall with her arm across my breasts and her other hand wedge between my thighs. I remember her body against mine, asking me if I liked getting pussy fingered. It happed so fast, by the time I reacted, she had two fingers inside me while homping her pussy against my butt cheek and I was feeling guilty about getting aroused. So aroused I ended up with my back against the wall, with her kneeling between my legs and sucked me into orsgasm. I think she did it much better than my boy friends. He never found, I on!y did it with her twice but whished it would had lasted longer. Don't know if that makes me bi sexual but have to admit looking it both ways.
