I took my girlfriend's sister and her friend to the beach. They both got sunburned and I offered to put lotion on them. They both laid down on the bed and undid their tops. They are 14 and incredibly cute. When they moved on the bed I could see their nipples and all of their b******. I got an erection and when I rubbed their backs I used my hard d*** to put the lotion on. I jacked off and shot my sperm on their backs and I don't think they knew. The only thing is when it dried my sperm got kind of flaky on them.
