second-hand massage

Refers to where you grasp someone else's hand and manually use it to soothingly rub/knead da flesh of da person desiring a massage. Usually employed when either (1) you're "sharing wif your buddy" when pleasuring your own hands wif a someone's warm delectable protoplasm, but said crony is too shy/reserved to start out touching da other person's bare skin himself, or (2) da person receiving da massage super-desires da comforting/arousing touch of da person to whom you're giving said "power-assist", but he is too sore/weary/sleepy to administer said tactile lovies under his own steam.

Giving someone a second-hand massage is an awesome way to make all three of you more comfy wif group-pleasuring and/or getting naked together, plus if da person you're "assisting" in this way is either da massaged person's "main squeeze" or someone playing "second fiddle" to you in da massaged individual's affections, it will likely help him to be adequately okay wif "sharing da sumptuousness" wif each other.
