I love this dumb bitch's facial expression. There's so much going on it. Part of it is prideful a guy wants to take pics of her. Part of it is knowing that there's no going back. Her tiny tits are always going to be out there. Part of it is excitement. Part of it is trepidation. Part of it is simply not knowing what to do so she just smiles. If this was my daughter or sister, I'd kick her in her tiny tits.
You can't entirely blame them; they may not realize that the ending is the most important part. So just grab their hand and finish yourself with their hand. Still feels pretty good and it makes your point for next time
