It's been a gorgeous couple of days. There hasn't been a cloud in the sky and both Mike and Monika look fabulous and have treated me royally, although I only got to enjoy Monika's body for the first time today. We have all been mucking about in the pool, stroking and groping each other, but I have always had to watch Mike fucking Monika. Today he threw me a cock ring and told me to put it on - 5 cm in diameter, thin steel ring. I had never worn one before and struggled to get it on. Over your balls first, he said, then get your shaft in. A tight fit, but it was on. He gave me a kiss, on the lips and on my cock and then said to enjoy Monika. She was on a sun bed, legs splayed, playing with herself. I went down on her and savoured her tasty juices. I love licking out girls, but she was one hot lady, positively dripping. I took my time, licking deep and playing with her clit. All the while my cock was growing larger and larger. Eventually I crawled up her body and slipped my cock into her pussy. It felt so good. I cried out and told them both. Mike got up and came over to wank over us. I rocked backwards and forwards, sending waves rippling over Monika's ample body. She sucked my cock into her and gasped and moaned. The ring felt so tight around the base of my cock. Her juices were spilling out and I tried to hold my cum as long as I could. She brought her legs up onto my shoulders and invited Mike to rub her clitty. My cock pulsed as I shot deep inside her. Sweat was dripping off us and she pushed my head down to her slick pussy. I licked and sucked her messy pussy, our juices freely mixed. My face was slick. I was in heaven and my stay has only just begun!
