I am in a public bathroom stall. I am so very horny and cannot help myself. I reach between my legs and start to masturbate. I try my best to be as quiet and unobtrusive as I can be. But as I cum a low moan escapes my lips and I accidentally kick the stall door open a little bit for just a sec. A woman accidentally opens the door thinking the stall is empty and embarrassed immediately closes it. I too am embarrassed, not sure what she saw. I finally pull myself together and get up to leave. As I'm making a final check in the mirror someone comes up behind me, quickly places something over my nose and mouth, and I lose consciousness.
I wake up to find my self bound and gagged and not alone. My head is somehow immobilized. There is a cock shaped dildo gag in my mouth. My arms are tightly tied behind my back, forcing my tits to stick out more than usual. My legs are bound up and back at knees and ankles, opening me as wide as I can be. I finally notice a small, petite, flat-chested woman -you know a woman that might be all of a size 3 β standing before me. She has dark hair to her shoulders and big black eyes. She says, "Ah I see you're awake. I hope you don't mind too much... I saw and heard you... Sometimes the need to get off is so great that you just can't deny yourself no matter where you are. I know the feeling. I thought maybe I could help you with that little problem." She laughs softly.
She unbuttons my shirtdress, revealing my ample 38C breasts wrapped in a purple satin, front hook bra. As she continues to unbutton my dress she uncovers a matching purple satin thong. She moans appreciatively. Her attention immediately goes back to my breasts. She cups them and squeezes and massages them thru the bra. Saying "Mmm such big titties. As you see that's something I don't have. But I do love yours."
