Family Ties/Go to the back of the RV.
You stop your sister and take her to the back of the RV. When you walk through the door you see that your mother has not done anything with Timmy yet, due to the fact that he is asleep. He is laying on the bed and your mother is laying beside him in just a bikini, one breast exposed and rolling a hard nipple in her fingers and she stares at your little brother. She notices that you are leading your sister by her hand
"Don't worry I'll leave if you need your privacy." She says in a whisper.
Before she can move from her position on the bed you stop her, "Mom you don't have to leave." Heather seems very confused.
With your little brother still snoozing on the bed you walk heather to the foot of the bed and pull her into a powerful lip while slowly fondle her breasts through her bikini top. Her nipples are already hard and you only just locked lips with her. You help her take off her top, when you feel that someone is taking off your sweats. You look down to see that your mother has taken off your sweats and has now moved to taking off Heather's tight jean shorts. You love how this has unfolded. With the help of your mother you and Heather are completely naked.
You decide that your mother should be relieved of her clothing as well, so you pull the strings of her bikini top while Heather takes off her bottoms.With out any prompting from you your sister starts eating your mom out while you suck on her luscious nipples. Your mother's breath starts becoming labored as she approaches an orgasm. So you decide to help out Heather, eating your mom out. With both your tongues licking your mother's cunny she can't hold it anymore and orgasms loudly, but is stopped when Heather locks lips with her to stop her. You then decide you should taste your sister and compare the taste between your mom.
It doesn't take you long to find Heather's G-spot and you get her to orgasm faster than your mom. The two ladies decide that you did a good enough job so they stand you up and they get on their knees. Your mom goes first and starts bobbing her head up and down while Heather sucks on your balls. Heather wanting a turn to moves your mom over and takes your entire length into her mouth. Your mom pushes her head back and forth making sure shes deep throating you. Your mom pulls Heather off and she does the same thing, it seems to be a competition between the two and you really don't mind.
