Brushed Erection Against Mom or Sis?

[Mrmojo49]

Wondering if there are others out there who've accidentally brushed their erection against mom or sis?

My sis and I were on a crowded subway once. There were no open seats and we needed to stand, and all those standing were packed in like sardines. The front of my body was pressed against sis' back side (actually my genital area was pressed against her cute tight butt, and she was wearing thin nylon shorts). Anyway, to my shock, I got a very hard erection. With all the stop and starts and curving of the subway, her butt ended up gyrating and grinding against my cock (which at that point was rock hard, pretty big, and sticking up straight north). When we finally got off the subway, I could see that she was flush ... but smiling

Hmm, maybe something you should explore further.

I had a similar on a crowed bus and was behind a mother and teenage daughter. The stop and starts the bus would make would push the mother against my crotch .After several stops the bus cleared out but mom stayed close by and would give a very a very sexy smile. The whole bus ride had a pleasant end as we both got off at the same bus stop and we both lived at the same apartment complex. What followed is another story.
