A surprise that left its mark

I'm Gianni, a 27-year-old young man, and I've been eagerly awaiting my encounters with my lover Angela, a busty 45-year-old widow. It was always satisfying to fuck a bitch like that, and that's why I didn't feel the need to get engaged, much less get married; I felt great. I must say, I'm not particularly gifted, but I think I know how to use it well, and she liked that. The last time I went to her with the usual excitement you feel when moments of pleasure await you, she rang, she opened my mouth, and she was already in her lingerie, waiting for me. She was incredibly horny, and I threw myself at her like a madman, but she stopped me: "Oh no, today I want something different, I want a lesbian relationship." I didn't understand, I was confused, but I soon realized her intentions. On the dresser in the bedroom was a set of lingerie that she ordered me to put on without question, telling me that we would make love like two women, a sensation she wanted to experience with me. Well... I try to please her, it's too exciting, I didn't want to risk losing her, what does it matter... that was the goal. So I put on stockings, a garter belt, a bra, and high heels, but it's not over: she starts putting on my makeup: blush, foundation, eyeshadow, mascara, lipstick, lip liner, and, to top it all off, a short black wig in a woman's style. She takes me in front of the mirror... incredible! I barely recognized myself!!! I saw a woman, and a very beautiful one at that, but never mind, now the fun begins! We start kissing on the bed, I lick her pussy, I give it to her mouth, she was horny like never before, I put it in missionary, then doggy style, then again.....but here the absurd happens.....while I was going at it, I feel something creeping up behind me, instinctively I push my pelvis forward to escape, Angela had already slipped out of my cock, I am grabbed by the ankles and the thrust of my movement makes me end up lying on my stomach, I immediately feel my legs spread and my wrists grabbed by an immense force.....I am immobilized with no possibility of reacting.....“Who is it? What's happening?”. “What's wrong? What's wrong?” - Angela asks me in an arrogant tone. I see her disappear from my sight and feel her touching my behind, I feel something smearing, meanwhile the beast that had me pinned down, firmly planted on top of me, didn't loosen his grip in the slightest and grunted like an animal. Angela comes back in front of me and still with that arrogant tone: "Now you're going to experience something you've never felt before!" At that point I was scared, I had understood what was about to happen to me, at a sign from Angela the pig aims at my little hole, a decisive push and the muscle gives, my scream of pain is devastating, it made me arch my head back, Angela caresses me as if trying to ease the excruciating pain of the ass fucking:“What's wrong? What's wrong?” he kept repeating. “Don't you like it? You'll see, the pain will soon go away and Arturo will make you enjoy it like a whore.” He was tearing my whole little hole apart, it felt like he had a tree trunk instead of a cock, then I realized that Angela couldn't settle for a little dick like mine and she was also getting fucked by that beast who stuck his pole in without regard for anyone. After an interminable time of him pounding me belly down, he made a rotating movement making me end up impaled on him on my back, I couldn't see his face, but he grabbed me by the hips and slammed me violently, he was tearing my whole little hole apart, I felt it in pieces, he was giving me terrible thrusts, with every thrust I thought he would tear it apart, he went at it for an interminable time accompanying the thrusts with explicit phrases: “You made me find a real slut!” or: "I would spend my life in bed with this whore", the fact is that he turns me over once again and, once again on my stomach, bangs me with an obsessive frenzy, heedless of my screams and my pleas, while Angela, seeing me in difficulty, caressed my face and hair almost tenderly. Time passed and I thought that the ass fucking would never end, at a certain point he started to gasp and screaming like a wounded beast, he unloaded an enormous quantity of boiling cum inside me, shouting at me: "Yesssss, take it all, I'll impregnate you, I'll make you pregnant!"
He stays inside me for quite some time, and when he pulls out, I hear a wet squirt. My hole is on fire, and Angela is the one applying cold compresses, perhaps knowing at her own expense what that tree trunk does to her. I finally see the face and body of that brute, a mountain of fat, incredibly hairy like a bear, and above all, that tree trunk, dangling almost to his knees. Scary, truly monstrous!
But despite the compresses, for several days I walked with my legs apart and had trouble sitting down. The burning sensation was an indelible sign of the trepanation. Now the question is whether to continue going to Angela: they've told me clearly that I can find him, but the price to pay is high, or maybe not?
