Now take that dildo...it should be nice and lube up from your mouth. If not, suck it for a few more minutes.
Place the head up against your ass...or, for now, you boy pussy. Slowly put some pressure on it until it slides in. Leave just the head of the cock in there for few seconds. Then, pull it out.
Feel how good that is, and then put it back in, just the head. Do this 20 times and then click...
