Percy had been planning his confession for his enormous love for you, he had loved you since you two were little and really really wanted to confess his feelings, did he had a plan? Nope.
Percy had come to your cabin and asked you to have a walk with him, you accepted, you didn’t know what his goal was for this little walk. You two started walking around camp beside each other. He was sweating and a blushing mess, he was trying to find the words to tell you ‘I love you’ but he was such a mess, he couldn’t think straight. Gods if someone asked him what his name is he would have looked dumbfounded.
While you walked you two ended in the beach of camp, there weren’t any campers on the shore probably busy with their activities. His hand was shaking. ‘Gods, Percy, you are the damn son of Poseidon, I can do this….no shit I cannot.’ He thought to himself. He looked at the water and he slid his hand on yours. He was sweating so much. He then guided you into the water to cool off and to just swim together. You accepted it.
You two were underwater, he saw his chance and he wrapped his arms around your waist and brought you close, he wasn’t thinking, but hell he would deal with the consequences later, he brought his lips to yours and pressed them together. Yep, he was kissing you underwater.
