Much larger in thickness than any of the other Motorbunny attachments, the Larger Attachment Cover is just that - a thick, realistic "tip" that can be slid on top of the Medium TPE Attachment. This turns the Medium TPE Attachment into a thicker, realistic dildo to play with. It does exactly as advertised. Getting onto the Medium TPE Attachment can take a bit of muscle, but it really helps if you attach the Medium TPE Attachment to the Motorbunny first - then the attachment slides on much easier. Even with lots of up and down riding, we've never had any issue with this Larger Attachment Cover sliding off. It really gets a good suction onto the TPE Attachment that requires a bit of muscle to pull the two apart again. Make sure you pay attention to the measurements for this thick, realistic cover! It's definitely not for those who like small toys!
