We pulled over to the far corner spaces and Joe pulled up next to the passenger side of the truck. "My turn to watch" Joe said to me. I looked at him,..."I'll ask" I said and got out and went over to the cab. I pulled open the door and this man looked a whole lot better. "My hubby wants to watch" I said to him, "That okay with you?" I added. Looking down at my exposed tits, "Only if I can fuck you" he answered back and I readily agreed and motioned for Joe to come along. His cab was really. “I want you to put that big cock into my cunt, right now,” she said in a soft sexy tone of voice.I obeyed my sister’s command, and immediately, my dick made way into her pussy. She moaned again. I grabbed her gigantic tits and began to thrust slowly. I kissed her neck, I sucked her skin, and made sure she felt pleased.“Fuck me harder, little bro,” whispered Valentina.I liked how she called me “little bro”, even though I was one year older than her. I began to fuck her harder, but without. " I know. But it's a little different. I love you the way that wants to kiss you and touch you, like I was doing this morning. You don't like that kind of thing. You don't ever have to feel you should do something that you don't like. Just because you are my girlfriend doesn't mean I don't have to follow the rules. In fact, it means I do have to follow them. I loved sleeping with you last night. And with Sam. But if we ever do that again, you can't let me do something that you don't want, too.. I was afraid to drive fast because we didn't know what had happened. Then, we met you."It all came out in a rush. Both of them were crying remembering what had happened. We rode in silence for a while.Lunchtime came and we entered a moderate sized town. We had lunch in a Wal-Mart parking lot and went inside for linens and anything else we thought we might need. I had shown the sisters what the beds were like. We came out with our items. We loaded the RV, stopped to top off the tank while there.
