Play a bit with Layla

You think about all the stuff they did and since you are Derek now you could do all that with Layla now. As you three head into the water you wait a bit till Mia leaves coz she has to go to the toilet. You swim to Layla and grab her from the behind. The water was so deep that the water was at your necks. You whisper in her ear "We are alone now!" You pull her close so she could feel your boner on her ass through your swim pants. Seeing that she grins you go over her stomach with your hand and let your hand sink into her bikini bottom. You feel that she was wet, but it wasn't water. She was horny as hell! "Oh, you naughty girl!" You whisper. You begin to rub her clitoris a bit as you hear her moan a little bit. She suddenly turns around and says "Derek, not here! Let's do it somewhere else!"
