She wants to try a titjob

Rachel scoots herself down the bed and takes my cockhead in her mouth. She licks all around it, letting her tongue play over my mushroom, then says in some surprise, “You taste good—salty and sweet.” After a moment she adds shyly, “If you want to cum in my mouth—I’ll try it.” I moan at the thought, which gives her confidence. She wraps her lips around my cockhead again and sucks hard, flicking it with her tongue. She bobs her head up and down my shaft several times, and I can feel the pressure building in my balls. Suddenly, she stops and says, “I want to try something.”

Rachel rolls over on her back and grabs one of her huge melons in each hand. “Want to fuck them?” she asks.

I scramble up with alacrity and straddle her slender torso as she pushes her twin peaks together. She’s left my rod absolutely dripping wet, so it slides easily as I hump her boobs. Their pillowy warmth wrapped around my cock is incredibly arousing, and every time I finish a thrust, Rachel sucks my cockhead into her mouth and licks it. She keeps sucking as I pull back, making an audible “pop” as I withdraw.

As I pick up speed, I lean forward and grab Rachel’s lush mounds. I squeeze them hard, pinch her nipples, and rub them against each other, increasing the motion. It’s wonderful to feel her huge, supple tits both in my hands and on my cock. Some combination of my arousal and my hands on her breasts has her quite turned on as well; I can feel her heart pounding through her chest. She slips a hand into her snatch and starts diddling her clit, and her heart goes faster. She continues to suck my cockhead with intense focus every time it appears, however.

It isn’t all that long before I’m ready to blow. Do I want to take her offer to cum in her mouth, or blow my load all over her incredible tits?
