I noted the depth and pulled back out. Eva reached in behind me and wrapped her fingers around my cock as I pulled out. It was slippery with Beverly’s lubrication. I pushed right back down to the same depth and Eva’s hand slid off my cock and cradled my balls. I watched Beverly’s face, which plainly relayed the pressure in her vagina and after a couple of strokes I could read the depth right between pleasure and pain in her eyes. I fucked her hard after that as my cock slid through Eva’s hand to quickly cup my balls before I pulled out again.
Beverly was moaning non-stop through a chant of, “OOOHHH…OHHHH… OHHH’s” that was in synch with my down strokes. Her chant rate increased with my pace and when I began piston fucking her with just the glans, she screamed out, “FUUUUUCCCCCKKKKK,” as she lifted her hips and held them there. Eva’s hand was still there gripping most of my shaft as I tip-fucked her sister as fast as my hips could go.
Without warning I drove my cock deep into her pussy and she screamed again, “OH MY GOD.” I took two full depth plunges and then went back to tip-fucking her. She was delirious as she rocked her head from side to side and grabbed her own tits to hold them down. They had been flying everywhere and that erotic sight raised the hardness of my cock and she screamed again. Eva kept her hand on my cock but she moved her body so she could watch her sister thrash around on the bed under me.
Beverly’s face and neck contorted into a mask of tight muscles and tendons. She was holding her breath as her muscles tightened even more and then she released the tension and burst out, “UNNGGAAAHHHH”. Her hips launched upward onto my cock as she drove her head and back into the bed. Then they reversed as her back arched raising her chest and driving her hips back into the bed. She screamed the loudest yet, “YES. YES. OH MY GAAWWDD. I’MMM CUMMINNNGGGG AGGAIINN.” She drove her hips back up as I cautiously pushed down. It was hard to gauge my depth with her driving her hips up like she was so I was conservative so I wouldn’t hurt her. She wanted nothing of that conservatism and she screamed again, “OH GAAWWDD. GIVE IT TO ME JACK. GIVE IT ALL TO MEEEEE.” I did as directed. She never flinched as my cock drove all the way to my bottom.
