Keiran Lee's new stepsister, Eliza Ibarra, is home from college and enjoying the sun in the pool. She doesn't know it's shark attack week, however, and Keiran has a surprise in store for her as he sneaks into the pool and flips over her inflatable mattress, causing her to lose her bikini top! Eliza, fed up with Keiran's pranks, thinks it's only fair that if he gets to see her tits, she should see his dick! Keiran dares her to try, and she manages to strip off his shorts. As soon as Eliza's eyes get a good look at Keiran's big cock, she dives in for an underwater blowjob before they head inside for a good dicking!
