I just stared and she pushed me back down on the bed, getting on the bed and stradling me. “Lets have some fun,” she said before leaning over and ...issing me, unbuttoning my shirt. I get hard very easily (even just writing this account) and soon I was naked, my wife of 25 years sitting on top of me. Marina stood up, turned around and removed her panties, giving me a great view of her pert sexy ass. My cock was already twitching, and then she turned around to face me. Her pussy was completely. Peter smiled as I began to tongue her pussy while he fucked her, occasionally letting my tongue lick the length of his shaft as he removed it and reentered Sara. Not one to miss out on the action, Amy began to make out with Sara once again. I removed my mouth from Sara and Peter long enough to ask him, How you doin, Pete? Breathlessly, he answered, It wont be long! Tell us when youre about to blow! Amy said. Peter somewhat nodded his head in acknowledgement. He continued fucking Sara, then sped. After a few minutes of her sucking on me, I decided I wanted to return the favour and also see this pussy that had so eagerly been rubbing against me. As I stood Erica up, she must have read my mind, as she reached down herself and pulled the knots on either side of her thong, and it just fell away. Right before me was now the shaved bare pussy of this 15 yr old teenage girl. I grinned and told her I needed to lick her. She smiled and jumped on the couch and spread her legs for me. I knelt. The blood building up in my dick had it really pulsating. We made brief eye contact again as she looked up at me again and quickly back down at her book. Then she spread her legs wide apart and slid down into her chair more so I could see her pussy as much as possible. Now my heart was really pounding and I could barely breathe.By now my throbbing erection was squeezing tight inside my khaki shorts pitching a rather big tent. I caught another glimpse of eye contact and then she looked around.
