Me 33(m) and my ex gf(27) took a trip to the beach to spend a few days! Both of us are exhibitionist so we liked to have fun! One night we went down the hot tub and my gf was riding me reverse cowgirl when i group of 18yr guys came to the hot tub. Instead of stopping my gf just rode a little more discreet. After about 5 minutes the guys realized what we were doing and asked if they should leave, we told them no if they dont mind! The decided to stay so I started to tease them by pulling out her tits and showing her off! My gf gets bold and ask if they are liking the few and that she wishes she could see their cocks. All 4 guys pull out their dicks and my ex being the slut she is started jerking them off. I can tell me gf is really getting worked up we invited them to the room. I fucked my gf doggystyle while one by one she sucked them off!
