hehe yep it will be over quick, trust me
i remeber my first time, the chick wanted to be on top so she could take it in slowley, it was her first time too and had some trouble getting it in her, it was so tight, and so wet and so hot inside, i almost cummed immediatley, thats how it goes lol.. shed sit down on it and just sit totally still with it stretching her and the minute shed move down furhter or move back up to get off, id cum, that h appned quite a few times untill she got a little looser
