Sex education starts in the bedroom! You're lounging in mom and dad's bed when your two sisters, Sydney and Nikko walk in. They want you to drive them to lunch but you have no desire to take them. Your sisters notice some condoms & lube sitting next to the bed and the conversation turns to sex and how to use the condoms. Both girls are virgins and are curious about what it's like. They want you to teach them some more about how it all works. Uncomfortable at first but very eager to learn, the girls take control of your cock and start playing with it. From gentle licking, the girls want to take it all the way. One of them licking your balls, the other with your cock in her mouth. Next up is trying to put the condom on. It's a lot different using a real cock as opposed to a banana. Nikko finally figures it out and wants to ride your cock first. For being a virgin, she sure knows how to ride a cock. You never imagined how hot it would be to have your sisters take turns fucking you. First Nikko rides you cowgirl then reverse cowgirl. She's a true natural at this. Then Sydney wants to take a turn. She slides a new condom on you and adds some lube before starting to ride your cock. She even takes in your whole big cock - Nikko is wondering where it all goes. Sydney also gets to take a turn riding reverse cowgirl. Looks like your sisters found a new hobby!
