A long road trip to your aunt's wedding means keeping to a strict driving schedule. Your girlfriend Holly knows this but as usual, she tests your limits. After stopping for coffee you noticed she slipped into a nearby sex shop and bought a new vibrator claiming you two can always use it when you get there. It's not long before you finally agree to take a little detour as she promises you won't regret it. Slipping into the backseat of the car at a busy truck stop she pulls out her new vibrator, leans back, and toys her clit and nipples until she has a hard pulsing orgasm. It's too much to handle as you pull her on top of you to ride until you cum hard, filling her up. (POV role play, solo masterbation, pulsing orgasm)
