Walks are never just walks

My first girlfriend and I (both totally 18) would go on walks to be alone. We'd walk down to this old barn and have fun. My favorite time was picking her up in the barn an pressing her to the wall. Thrusting into into her tll her legs tightened around me and I came in her. Just as that happened two people showed up and got hay out of the barn. We hid till they were gone then fucked again bending her over some farm equipment
