As he crawled on the bed on all fours to his naked sister-in-law, she sandwiched his face with her hands and planted a kiss on his lips. Her skillfull... soft lips made his heart catch and his erect penis waggle like a metronome gone wild. Leaning into the kiss he opened his mouth and accepted her searching tongue.Pleased that he’d accepted her brazen overture Beth grasped his rigid penis and wrapped her fingers fully around it. It wasn’t Josh’s bulk but was still pulsing and purposeful. The size. I parked about three car spaces down and as usual. I waited for a signal that they were ready for fun.After waiting for around five minutes, in which time I could only see the Hubby through the dim light of his mobile phone, the woman appeared at his side and I could just tell in the darkness and from the light off of the cars dashboard that she was taking her top off. This was good enough for me to have a casual walk over to hopefully see some action.Upon arrival I noticed that the driver’s. I nervously asked if her husband would be ok with that and she said if I was happy to do it, she’d run it past him to check first.I replied yes I’d do it and she gave me a quick kiss on the lips, poured me a drink and continued tidying.It had been on my mind a few weeks but I didn’t message either of them and then out of the blue on day at work I received a message from her asking if I could come to dinner tonight.I said sure, that would be great, and she replied it was the least they could do. I moved closer to him, my lips warm and fiery on his chest as I bit him hard… He tensed up shuddering… just the way I love it on him. Kissing continued as well as his moaning and shivering to my cruel touch of fingernails… I pulled him back slowly to the bathtub… Stepping inside. He followed stumbling his way there as a result of being dragged by me. After a while of intense kissing in bathtub I forced him down… he resistively complied. I made him lay back on the floor of tub with me on top,.
