This has happenned twice already with two different girls, I am having sex but they don't want to suck my dick or any other position than missionnary and kept pulling my head towards their faces. Where they insecure? Both were a bit chubby but a solid 6-7 (above average thanks to a nice face or big boobs). Honestly it trew me off both times and in the end I feel like the sex could have been a lot better... After that I didn't see the girls again.
