This spandex one piece thong couldnt stay in place at all! My boobs are always out... Im dominating entropy all the way in that first part....headlocks, grapevine, facesiting, reverse headscissors.... ok, yeah, he is weak...and Im not helping by touching his dick all the time to make sure he will stay hard so he cant concentrate.. Im touching my boobs because I know how to get him weaker!!!! he tried to do a wedgie to me with this small thong, but Im still stronger and in control! :-))))
