The sick feeling in my stomach returned."Doesn't he have a magnificent cock Brian ?" cooed my wife."Yes" I mumbled grudgingly."Tell him then" she snap...ed."You have a magnificent cock, Sir" I told him feeling totally humiliated."Thank you" he replied mockingly, "and later on it is going to be sliding into your wife's cunt right up to the balls, while you stand by watching helplessly". This caused them both to roar with laughter.After the meal, Jason said "I think it's showtime, let's all go. Sara and Matty stayed with their drinks and Caz wandered off back under the pier. As she did, Sara says "Go talk to her and tell her shes hot, cos I am sure you think so!" I hopped down, went to find her and when I did, I mentioned that I'd been sent along. Caz said she was okay and very sorry about her friend being so forward. But I said "well you're very nice, quite a catch and it's a pity you have a date already"Within a moment, she said "Hey, I have no objection to an older man, but don't. She moaned, I moaned LOUDER….and Greg simply watched.I rocked back and forth a bit, and within a couple minutes I probably had about 5 inches in her and began a gentle lovemaking motion of this 13 year old princess as her brother’s face was mere inches away. My nut sack was actually brushing his head and forehead as I entered her…I loved this. Greg did not know what to do…so I thought I would push the envelope. “lick her like you were Greg…she will like this more and suck you even better”. . Oh yeah! Robin just stayed there on top of her sheet and I fell asleep. Waking up the next morning she asked me if I wanted to do it again. Hell Yes! So we made love again, then we both showered together. We went out for the evening to a lovely restaurant and had clams and champagne. I wooed her with small talk and held her hand and kissed her. Playing with her feet under the table I hinted that I wanted to head back to our dorm for a fuck. Robin stripped down to just a sexy pair of panties for.
