I rolled my tongue around her Areola & gave light bites in between on her nipples, while simultaneously I was rubbing her vertical lips down below ove...r her panties. I used to slip my fingers from the side of the panties at times, her panties were drenched in precum, the flood gates were already open & her echoing moans were making me more mad. She pleaded me to fuck her, as she might have reached her limits by now, as it was almost 15-20 minutes of rubbing. I took a break left her starving for. The abandoned Amber had gravitated across to Riley, and she kissed her in welcome. With a look of unspoken request from the Prof she pulled off Amber's lacy panties and manoeuvred her over his lap, her super slim legs either side of the bulk of his muscular thighs, his cock tall and vertical in anticipation of her tightness.Riley took his cock by the root, and, with her other hand on Amber's small buttock, guided them together, parting her thick, dark pussy lips with his glans, stroking it on. It still sent shock waves up her body, and it took some courage finally to immerse herself totally. After a few seconds the pain subsided and she began to almost enjoy the experience - to her surprise!They swam together and paused between lengths to exchange the odd word."Why is this pool not drained for the winter" asked Harriet.One more length."Her father's a lunatic, that's why!"Another length."Swims every day all year round. Complete and utter nutcase!"They completed twenty lengths and saw. Sirinna nodded, then waited quietly, knowing that there was still more to that thought on Amanda's mind.Amanda sensed this and lowered her voice further. "He's... he's a little rough with me, Mistress."Sirinna's face took on a note of concern. "Amanda, is he hurting you?"Amanda shook her head quickly. "No, Mistress, he's not." Please, don't be afraid to tell me if he is. Master Roquan does not care for people abusing his slaves. And... I don't want to see you hurt, either." No, no, really, it's.
