When you finish she joins you in the tub again, this time she sits between your legs with her back to you, leaning back into you. You put your arms around her and the two of you just relax in the warm water. You start massaging her breasts and nipples, and kissing her neck. You can feel she is totally relaxed and absorbing the pleasure you provide. One of your hands wanders between her legs, gently massaging her inner thighs, never touching her pussy.
Her back is against your chest, and you can feel her sharp intakes of breath as you have her aroused. Her breasts lifting and falling with each deep breath. Your hand wanders to her pussy, just brushing against the labia, never penetrating at all. One finger pushes in, just slightly, working the slit, up and down. You press your palm against her clit at the same time, slowing rubbing it in a circle. She is yours now, completely engulfed in pleasure. You continue to work your finger, then two, then three, into her pussy, teasing her. Your cock is completely hardened now, pressing against her back.
You remove your hand from her pussy now, and just sit while she recovers, holding her in your arms. Finally she leans forward and lifts herself up out of the tub a bit. You feel her hand around your cock, startling you a bit. She chuckles and strokes it a few times. She sits back down now, this time you can feel your cock against her pussy, she rests on your hips as she lowers herself onto you. Your cock fills her slit, she moans softly, cooing to you, and you join her with a moan as well. She just sits, having completely taken you into her. Her tight pussy massaging your pulsating cock. You put your arms around her again and hold her tight. She loves sitting like this, and you are starting to love it too. She adjusts herself on your cock, somehow getting one last bit of it inside.
Slowly, very very slowly, she starts to raise up off your cock, then lower back down, up, down...over and over. You can't stand how slow she goes, but you love it at the same time. She is so sexy, so erotic, so in control. Her pace never picks up surprisingly, as she rides you through her first orgasm. You start to buck your hips against her, trying to go faster, but she whispers for you to be still. She keeps her pace, and you start to feel an orgasm building in your testicles. Slow...she keeps riding...so slow. Your cock starts to tense up, swelling even more with the coming orgasm, and she feels it. She stops, waiting for you to calm down.
Then she starts again, this time a bit faster, until you are near cumming. Then again she stops. Once you calm again, she starts again, this time much faster. Water splashes out onto the floor of the bathroom, but your lustful fury of hip grinding continues, growing in momentum with each thrust. Your hips bucking like crazy, hers doing the same. You feel her tighten up on your cock, another orgasm washing over her. Your own orgasm flashes over you, and you ejaculate into her, moaning as it hits. She is moaning too, cumming with you.
You both sit there, you holding her again, breathing hard. She kisses your cheek and you do the same to her, whispering into her ear that you love her. She smiles and says the same back. As you both calm down you notice the water is cooling off. Time to wash up. Time to get on with things until another bath begins.
