Girls, Why does her body shakes and pussy twitches over my cock while she rides my cock? Am I big?

[timfreddo]

I often feel her pussy contracts and her body shakes... While she's on top of me... riding me

It doesn't have much to do with the size of your dick.
It's normal for any girl's vagina to switch/shake during sex. That's just one thing that happens in response to pleasure, or her getting closer to climax.
