After that first cock-sucking session with Harry there was no stopping my hunger for his cock!
The thing is, I was not at all attracted to men in any way, not their bodies, their faces, their mannerisms, nothing. I loved women in all shapes and colours and dated and played around with them as much as was possible in those days, but the very thought of cock, actually of Harry's thick, hot ten-inch, cut, cock was enough for me to get a hard on.
But yes, I had to admit I had started to loved cocks!
Harry and I kept meeting for heated sessions as often as possible.
Once about four or five of us went to a holiday beach camp nearby for a couple of days. We had rented a bungalow where we would all sleep in the 3 bedrooms, each with two single beds. It was a great first day. Beach, swimming, barbeque and beer and lolling around taking in the sun and the view of bikini-ed girls who would also join us.
On this particular evening we had more or less paired off. I was with a slim blonde called Natasha, lying back on the still-warm sand as the bonfire we had lit died down, letting the night darkness hide our surreptitious fondling and heavy kissing.
Natasha and I were going at it and I had managed to slip my hand under her bra top, holding a firm young tit adorned with a stiff pink nipple that stood to attention when my tongue licked it.
"Bite it a bit." she breathed.
I did, gently, making her squirm with pleasure.
"Your cock is so hard." she said as she felt me press it against her body.
She pressed against me and despite her bikini bottom and my Speedos, I could feel her heat and she, mine.
"Touch it. Touch how hard I am for you." I urged her.
Her hand slipped inside and she held it, squeezed it and pumped it as best she could. It was a great feeling and I wanted to share it with her even more. My hand went to her mound. It was damp from her juices, soaking the material of her bikini. I wanted to slip my fingers inside, I wanted to slide them into her young, trimmed cunt and get her hot enough that we could have a discrete fuck in the open on this dark night on the beach.
Around us were other couples doing the same thing. I could hear whispered conversations and the occasional grunts and sighs announcing the pleasures each was enjoying.
Just then I felt a hand on my bum!
I could not turn around as Natasha and I were too engrossed in kissing and playing with each other. But I knew Harry was there, behind me, with a big-busted, older woman, a waitress he had snagged. Apparently, they had played with each other as much as they could and had both cum and were relaxing and hugging just next to Natasha and me.
Harry continued to touch my bum discretely.
The waitress must have dozed off and Natasha was too engrossed feeing my finger enter her very wet cunt.
I could not turn around. I did not want to spoil the surreptitious session I was having, and Harry realised it. So he took advantage and slipped the side of the Speedo from my bum, leaving half my bum exposed to his seeking fingers. Natasha was humping my hand; I was humping hers where my cock was being wanked by hers.
Behind me, Harry's hands parted my bum cheeks and he slipped a long middle finger, apparently lubed by the waitress's pussy juices, into my own hole.
"Ah!" I breathed, as his finger entered me deeper than ever before.
Natasha asked in a hoarse whisper: "Sorry, did I hurt you?"
"No, no. Keep wanking me, don't stop." I replied.
