I think if there is no problem with getting pregnant or getting sexual transmitted disease then can be very sexy when a man cum inside me without condom...
Is a sensitive subject. Of course, not all women would like to be in this situation and we need respect this but I have this experience before (full bus) and at the time I liked! I think if you want this to happen more times then is kink, no??
My car is in the garage being fixed so I needed to use crowded but to work and one older man,smaller than me, was pressing himself against my chest when the bus moved (but not all the time)!! I liked!!
