Why so shy and embarrassed?  You can relax, there are no strangers here, we have all rammed our cocks into you and dumped loads in your tight little ass. You don’t need to be ashamed of your small dick, none of us care about that. 

In fact, if it is bothering you so much, you can go put on a jockstrap. That way your little dick is tucked away out of sight, while your hairy ass is framed properly and fully accessible for us to use. After all, we used to be friends, we want you to be comfortable while we run a train on you.
