A few close friends got together, alcohol and illicit substances were enough responsibly when everyone decided to take a spa. Some had swim wear, I stripped down to my underwear, shear mesh boxer briefs that I knew when they got wet became nearly see through & barely concealed anything, my cock clearly visible when dry. The girls giggled and loudly said they thought I’d jumped in naked then realised my underwear was almost my skin tone. The jets in the spa fire a slightly stronger burst every now and then not only stimulates my anus, it forces its way into my arsehole add even more thrill aswell as another jet that blasting a swirling jet at the underside of the head of my cock, over one of the most arousing spots on my cock & the combination of both water jets easily and very quickly brings me so close to jizzing where I sit, only bubbles disrupt the view of me using the jets to get myself off erotically. I let the water jets make me extremely horny. So much so that I become extremely hard & erect & I subtly start stroking my now fat veiny cock under the spa bubbles allowing the pleasure I’m giving myself wash over me. My eyes shut for a moment & I gasp, ‘oh fk me that feels so fkn good’, softly. I’m sure it’s obvious that I’m masturbating, which thrills me but no one has said anything to me so I carefully continue, only making myself more sexual aroused & for some reason, braver as I slip my underwear down to my knees. The jets now have uninterrupted access & I use both hands to hold my raging hard-on , in the perfect position , using the jets to edge myself. I almost make myself jizz several times within meat minutes, causing my throbbing cock to ozz pre-cum, I’m so fkn horny now I let my underwear slip off my legs, catching them in my hand, now I can fully spread my legs to let the water jet access to my arsehole & cock. I lift one leg up on the top of the spa letting the jet penetrate my arsehole, I can feel the water inside me as I edge myself ever so close again to climax over & over again for 30min. I casually reach outside the spa for my smokes exposing my nudity with my bare arse president to my friends. Both girls have a clear side view of my hard cock & I can feel their gaze on my shaved cock & balls, fk I love them sneaking looks at my package so I linger, taking my time lighting my smoke then turn around while sinking back under the water allowing my hard cock to be fully seen ever so briefly before finding my water jets again , I throw my undies out onto the deck, there is no wondering now, everyone saw my throw them from the spa & smoke my cigarette with 1 hand & casually stroking my hard cock hidden by bubbles as we all chat & between bubbles cycles I don’t stop stroking myself everyone jumps out after about a hour but I stay because I’ve been so close to nutting several times I need to bust a nut now. Now I have the strongest jets and within 5min im once again on the verge of cumin. The blasting jet push me over my pleasure edge , I’m openly moaning as start climaxing, my cock & balls tighten & rhythmically throb & I pump ropey semen into the spa, I managed to stand to see the last few pumps of seed spill from my fat throbbing cock, falling into the water. I’m sitting on the top of the spa now stroking any semen left from my cock in the satisfying glow of a orgasm. I know there are multiple security cameras around this home and I wonder if footage will be gone through and watched. I hope they do. Wonder were things may go from here..?
