I finally just held my cock and gave a big shove and the tip of my dick went in. Nothing more, just the tip.So, I kept pushing forward and slowly, slo...ly, my cock began to go in. Once I got about halfway inside, I pulled back a bit, then pressed hard and I went in further.I looked over at Beth's mom. She was sitting in a chair, naked as we were, fingering her pussy in and out, rubbing her clit with her other hand. She did look very sexy there with her legs sprawled masturbating as I fucked her. Two probing fingers slipping deeper and deeper inside her as she imagined his hard cock doing the same.“Mmmphhhmmm!” she said, her mouth crammed full of titflesh, making it an effective gag.She sat there in the toilet stall with her tits bared, her dress hiked up around her waist and her panties around her ankles, exposing her wet pussy.
