Walked in on one of my friends getting pounded doggie-style by his bf. Two unwashed greasy hairy nerds just going at it, and lube dripping all over the carpet from the "point of entry." As soon as I walked in they started screaming incoherently and the one guy pulled out and ran into my buddy's closet. My friend just yelled "SURPRISE" like the autist he is and at that point I ran out. Now he gets really embarrassed whenever we mention it WHICH HE SHOULD BE. He never made any indication beforehand of what they were doing.
