Boner Expansion Pack includes two stackable TPR rings that restrict blood flow for harder erections and intensified orgasms. Compatible with existing Boner Kit components, these square donuts adapt perfectly to your anatomy while allowing endless customization possibilities for enhanced stamina and sensitivity.
Key Features:
Two stackable TPR cock rings enhance erection firmness and stamina through targeted pressure around the penis base for prolonged sexual performance and increased sensitivity during masturbation or penetration.
Square donut design with 1.3 inch exterior and 0.9 inch interior dimensions provides unique pressure distribution that maintains blood flow restriction for stronger erections and delayed orgasm.
Super stretchable thermoplastic rubber construction adapts to different penis sizes while delivering comfortable compression that enhances arousal without pinching or restricting circulation during extended wear.
Stackable functionality allows customization of intensity by using single rings for mild enhancement or combining both for increased constriction and enhanced sexual stamina during intercourse.
Compatible with existing Boner Kit components for expanded configuration options that target different erogenous zones and provide varied stimulation patterns during solo or partner sexual activities.

Sport Fucker's expansion rings work by applying targeted pressure around the base of your cock, trapping blood inside the shaft for thicker erections and heightened sensitivity. These two stackable squares can be worn individually or combined with your existing Boner Kit for completely customizable intensity levels.
Once you slide these rings on, they grip snugly without cutting off circulation completely. Blood gets trapped in your cock, making it noticeably thicker and more sensitive to every touch. Your erection stays harder for longer periods, and when you finally cum, the restricted blood flow intensifies every contraction. The square shape distributes pressure differently than round rings, hitting specific nerve clusters that add unexpected sensations.
Stack both rings together and the pressure doubles, creating almost overwhelming sensitivity. Your cock becomes hypersensitive to friction, temperature changes, and the slightest movement. Partners notice the difference immediately – you're visibly larger and stay rock-hard throughout longer sessions. The TPR material warms to body temperature quickly, so there's no cold shock during application.
Apply when semi-erect for easiest fitting. Stretch the ring open and slide it down to the base of your cock, positioning it snugly against your body. The TPR material stretches easily but recovers its shape immediately. If using both rings, space them slightly apart or stack them directly together depending on your comfort level.
Start with shorter wearing sessions – 20 to 30 minutes maximum until you understand how your body responds. Remove immediately if you experience numbness, discoloration, or pain. A small amount of water-based lube on the inside edge makes application smoother and removal easier after extended wear.
Perfect for guys who want more control over their erection quality without committing to complex devices. If you sometimes lose hardness during longer sessions or want your cock to feel thicker and more sensitive, these rings solve both problems elegantly. The stackable feature appeals to users who like experimenting with different intensity levels.
Avoid if you have circulation issues, diabetes, or take blood-thinning medications. The 0.9-inch interior opening works for most men but may be too tight for significantly above-average girth. Complete beginners should start with just one ring before attempting the stacked configuration.

While primarily a cock ring, this expansion pack complements prostate exploration by helping maintain stronger erections during anal play. The blood restriction keeps you hard even when focused on internal stimulation, making it easier to enjoy dual sensations simultaneously.

These rings work excellently underneath penis sleeves, helping maintain the erection needed to keep sleeves positioned properly. The extra girth from blood restriction fills out sleeves more completely, preventing slippage during vigorous activity while maintaining sensitivity.

The Boner Expansion Pack immediately impressed me with its versatility. Starting with one ring, I noticed my cock stayed harder throughout a 25-minute session without any loss of sensitivity. Adding the second ring doubled the intensity – almost too much at first. The square shape hits different pressure points than my round rings, creating sensations I wasn't expecting. Blood restriction was noticeable within 60 seconds, and my partner commented on the visible size difference. Removal was easy even after extended wear, and the TPR material never caused irritation. The compatibility with other Boner Kit pieces means endless experimentation possibilities. These have become my go-to choice for longer sessions.
