The bedroom was cool; the blinds were closed, keeping the room in the shade. It was a hot summer day, and the sun was high in the sky outside, without a cloud in sight. She was standing in front of me: she had put on a purple swimsuit to go to the local beach, which was only a few metres away. In the relative darkness of the room, the freckles on her skin were appearing clearly, like constellations in the night sky. I could not turn my eyes off her heavy breasts outlined by the thin material of her new swimsuit. And then, the thought of my girlfriend, lying down on the beach, with older men staring at her, at her legs, at her arse, at her big breasts, hit me, and turned me on like crazy. All those pervs would look at her drooling, wishing they could have her tight arse. Amused, she could see I was getting really aroused, and she gave me a cheeky smile. She turned around, to show off that one-piece swimsuit she had just bought.
I could no longer resist, I grabbed her arms, and started kissing her like a mad man. I drew her against me, and started to strip her out of the swimsuit. I then turned her around and pushed her against the wall. She let out a gasp, surprised by the intensity of my actions.
I grabbed her left hand, and pushed it against her pussy. “Touch yourself,” I whispered. Slowly, she started caressing herself, as I took her other hand, and, after sucking her fingers, I pushed it between us, against her anus. “Play with your hole” She whimpered, and I could feel her hand getting busy against my cock, still prisoner of my clothes. I stepped back to look at her, and satisfied with the scene of my girlfriend being so dirty, I opened my fly to let my dick out.
She was now wriggling against the wall, one hand turning on her clitoris, the other one with two fingers firmly inserted into her arsehole. I grabbed my cock, approached her, and as I pushed her arm aside, I whispered to her ear: “I am going to take your virgin arsehole, like those old men on the beach will want to.”
She moaned as I started to enter her, slowly, while she was still furiously masturbating. How tight she was! In one firm push I was fully inside her, and I knew I would not hold long…
