Couple has anal sex the first time

Jim and Joan are delighted to be together, but it's a bit awkward to make love. It's like they have to pretend they're not horny all the time, so when they finally get into the bedroom, they start kissing. They decide to get naked so they can get comfortable, and when Jim starts sucking on Joan's tits, she gets so turned on that she wants to fuck him right then and there. She climbs on top of him and starts riding his cock, but she doesn't have much experience, so she keeps getting nervous. She needs a man who knows what he's doing, so Jim helps her out by pulling out his dick and letting her suck on it until he is hard enough to fuck her.
Jim takes off her panties and starts pounding her tight little pussy while she moans with pleasure. It doesn't take long before Joan screams in orgasm, and she can't stop cumming. After they finish, Jim lays down next to her and kisses her tenderly as she cuddles up with him.
