While he was doing that I was sucking hard on his tongue, lips, neck, I wanted his length in my mouth now! But he wouldn't let me off his lap. Suddenly he quickly pulled my bikini completely off, whipped out his huge, hard length and settled me in on top of it. Oh man he was big and filled me up! I started to ride him quickly I was so horny while he was holding my hips and trying desperately to slow me down. It just felt so good I had to go fast! I don't know what made me look up but just then I looked over his shoulder and saw a very attractive couple standing there staring at us! I kept riding him, I didn't care that they were there watching us, in fact it turned me on even more! Then without saying anything they got in the tub with us, sitting very close to us still watching...
