"Yes, help her take it all"

Quinn kisses you hard then puts her face right next to Robin's, watching her repeated attempts to push your cock down her throat. "Mmm, there's your problem," Quinn shares as she grabs Robin's throat. "You're not relaxing your muscles here.". Quinn's voice is calm but authoritative. Robin gives a muffled, somewhat concerned squeal into my cock at the feeling of having a hand on her throat. Robin looks up at you even more concerned as Quinn grabs Robin's hair in a fist at the back of her neck. You give her an assuring look. Quinn wouldn't do anything to hurt her. Would she? You didn't think so, then again you had no idea she was eager for your cock until a few minutes ago.

"Relax your jaw," Quinn instructs Robin. Her hand is still on Robin's throat, so she knows when she's relaxed. "Good, now..." Quinn pushes down on the back of Robin's head and down she goes on your cock. For the first time, you feel your cock slide into Robin's throat. Your flash of concern for how she will feel about her cousin forcing her down is quickly overtaken by your pleasure.

Quinn shoves Robin's head up and down several times before pulling her all the way up. "That's it you dirty little slut, take your brother's fat cock deep." Robin is gasping for breath, tears from gagging starting to come from her eyes. Quinn gives her a messy kiss. Robin looks like she's struggling to come to terms with everything, the mix of dominance and affection confusing her. "Mmm, Michael your cock tastes amazing on Robin's tongue. But first, Robin needs to finish what she started."

With that Quinn forces Robin back down in your cock. You moan again, and since Quinn is taking care of holding Robin's head, you find that you're hands are free. You look at Quinn's sexy body so close and decide to finally feel it. You reach out and grab her tits through her tank top. She moans gently and turns to make them more accessible to you. She smiles at you, and after you continue to play with them, she pulls her tank top over her head. Her demi bra shows plenty of her amazing tits. You moan, thankful that Robin probably doesn't realize it's more for Quinn than her. You grab Quinn's tits again and this time pull her closer to your face.

You kiss the bare skin between Quinn's tits and reach around behind her, unclasping her bra and pulling the straps off the shoulders. You admire how her tits are large, probably DD, but held up so well even without a bra. You lick and suck her tits like a kid in a candy shop. Quinn moans more now and forces Robin up and down more rapidly on your cock. "Fuck yes, play with my tits Michael. I want you to cum in Robin's mouth while my tits are in yours."

It's so fucking naughty, but you find that you love it. You can feel your orgasm coming on fast after Quinn eggs you on. You bite down slightly on one of her hard nipples and she throws her head back moaning louder. She feels for moan into her breasts getting louder and knows you're going to cum. You feel her **** Robin's head down on your cock and hold it there as you start to empty your load down her throat.

The combination of both ladies feels so good and you cum hard. Before you're done, Robin jerks back up, needing to breathe. Quinn holds her head close. What didn't go down Robin's throat is now all over her face. When you're orgasm is over, Quinn pulls back and turns to face Robin. Robin at first looks a little scared, but still very aroused with her nipples as hard as you've seen them. Quinn surprises both of you as she takes Robin's head in her hands gently this time. Quinn starts licking your cum up, cleaning Robin's face shot by shot of your sticky cum. It's so hot that it keeps you hard watching.

When Quinn is gone she gives Robin a long passionate kiss and her hands caress Robin's sexy body. Robin reciprocates and quickly it's an amazingly sexy topless makeout session. Quinn breaks the kiss, smiles and Robin and gets up from the couch, pulling Robin with her. Quinn lies on her back on the bed, her pussy right at the edge of the bed, legs hanging off. "And now my pet," Quinn says seductively between kisses, "I think it's time for you to share Michael's beautiful cock with me. Be a good girl and get my shorts off."

Quinn said it was if it was the hottest thing for Robin. You almost didn't catch what she was saying, and wondered if Robin would continue to play along. Letting you play with Quinn's tits was one thing, but would she allow, let alone assist in, you fucking your sexy cousin?
