I felt a chill run up my spine after hearing a noise - footsteps, and I moaned as a way of communicating my concern to John, but he quietly chuckled and continued to lick and suck my cock. Finally I was able to see whose footsteps I heard when he was beside the bed and John's thigh no longer blocked my view. The guy had medium length blonde hair, was above average in height, fairly defined muscles, but still pretty slim, and a nine inch cock that was already wet with lube. He tossed a black cloth bag toward the head of the bed and when it landed it made a quiet metallic clinking noise, which I assumed were his keys along with his clothes in the bag.
He then got on the bed, kneeling behind John and slowly pulled John's butt plug out - never breaking eye contact with me as he did so. He tossed the butt plug aside and then slowly started feeding his long dick into John's ass right before my eyes. I felt John tense up a bit and then relax as the newcomer started with shallow pumping and worked up to giving John the full length. Despite the show of his massive balls swinging back and forth in front of my eyes, I was starting to feel left out - that is until I felt someone lift my legs up off the floor to rest them on their shoulders. There was a second stranger in the room! My mind was swimming with fears and questions, but with John's dick in my mouth I had no way of letting them out. Then my butt plug stopped vibrating and it was slowly being pulled out of my anus. I was feeling nervous and uncertain, but it appeared as though I was going to get my wish of being fucked in the ass whether I liked it or not! I felt him press his knob against my well-lubed, but inexperienced asshole and he just held it there for a while. My mind rushing, I remembered to try to relax my ass and push just like when you are taking a shit. He must have picked up on what I was doing because as soon as I started pushing, I felt him slowly pushing into me. It hurt a little when his knob popped in, but he held it there for a minute as my body got used to his girth. He then slowly started shallow pumping in and out, gradually working up to full length thrusts into my thirsty asshole.
The sights, sounds, and sensations were making my head spin. "What must this look like?" I wondered. I imagined the sight of me and John in a sixty-nine, each of us having our asses fucked at the same time! I was beyond horny, but I was getting jealous feelings - it was my birthday after all - I wanted all of the cum. I pushed up gently on John's hips to pull his dick out of my throat so I could give his knob my full attention. I tightened my lips and bobbed up and down while flicking my tongue quickly over his prepuce. I felt John tense up as he started to ejaculate into my mouth. I felt John's mouth leave my cock and he said "Well aren't you greedy? I'll let it slide since it's your birthday. I'm going to get a drink - have fun with him Nathan and Steve." After he said that, the blonde guy pulled his cock slowly out of John's ass and I looked up and licked my lips.
"I'm Nathan by the way." he said as he slid his cock into my mouth. John climbed off of me and left the room. I was left with Nathan's knob in my mouth while a man called Steve who I realized I hadn't seen yet was busy fucking me in the ass.
"Looks like you can suck a mean dick," Nathan said, "let's see if you can take all of me down your throat."
I nodded and relaxed my throat, pushing my tongue out as far as I could along his shaft to try to accommodate his long dick. I was pleasantly surprised that I was able to take it all right away. His cock was nine inches long, but it was about the same thickness as John's - besides - I had a few years' practice deep-throating sausages when I was still in the closet and fantasizing about sucking cock.
"Steve, we've got quite the cocksucker on our hands here, mate!" Nathan exclaimed as he withdrew his cock from my mouth. A moment later, I felt Steve slowly pull out from my ass and Nathan gently lifted under my shoulders. I took the hint, got up on all fours, and crawled toward Steve at the foot of the bed. Steve was about 5'9", had short brown hair, a bit of a dad bod going on, and a seriously thick eight inch cock. He stood at the foot of the bed as I crawled toward him, staring at his penis. I licked my lips as I got closer and Steve chuckled as he said "Patience my friend, I have unfinished business with that tight pussy of yours." I felt myself blushing as he said it.. not because of his emasculating comment, but because I was flattered that he was enjoying my ass... as far as I was concerned he could call it my pussy any time he wanted. After he said that he walked around the bed and stood up behind me while Nathan took his place at the foot of the bed with that tasty long dick. My hands were gripping the bedding on the end of the mattress, my knees were together, and my ass was in the air, waiting for Steve to fill it again.
It happened so fast. I heard that clinking metallic sound again and suddenly felt cold steel on my wrists! My arms were pulled back from under me and I felt that cold steel on my ankles immediately after. Steve had put 2 pairs of handcuffs on me before I knew what was happening - one binding my left wrist to my left ankle, the other my right wrist to my right ankle, and my neck was resting on the edge of the mattress with my knees together under my chest.
